@@DarrenMostyn How do you calibrate your reference monitor? There's so much conflicting info online
Hey Darren, great vid again :) Maybe I missed it, but I wondered at some point why you would get something more expensive than a simple Mini Monitor with an SDI output if you don't need more than a signal going into the calibrated screen. Even using hardware scopes, those always have an output so you can daisy chain it forward to the screen. I see you have the Ultra Studio with the little screen on it, which looks great in the suite and I believe it has more inputs/outputs. But if your setup is only for color grading, without any capture/recording going on externally, would you say there's a point in getting more than a Mini Monitor 4K?
Good question. We have mini monitor 4K as well as the extreme rack mount. I have SDI and HDMI coming out all the time but also XLR audio output. It also can be connected via PCI extension card and it is rack mounted which fits our studio set up. But yes, no real advantage over that - same quality of signal. Hope that helps.
Hey Darren, thanks for sharing this. I was wondering, would you ever consider creating a video showing how to calibrate monitors, including the best tools to use? Thanks
No. I get mine calibrated by professionals.
Hi Darren, great video once again! Very informative! I was wondering the new resolve update, they have moved the power window outline from the view tab, to be able to turn it off, any idea if they have moved it elsewhere please?
Great stuff Darren. Am I right in saying that enabling the Mac color profile option for viewers maintains consistency between the Resolve GUI and Mac GUI environments i.e. there will be no gamma shift between the Resolve viewer and the Mac viewer (like QuickTime)? However, am I also right in saying this would not address the gamma shift when viewing in other environments (like on the web for example, which uses a different gamma compared to the Mac GUI)? Basically, we are relying on vendors (CZcams, Vimeo etc.) to implement a tagging system that recognises/adapts the output to account for differences in Mac GUI gamma?
Two very interesting videos today. Thanks Darren.
Thanks Ray. Appreciated as ever.
Great Video! So happy I stumbled across your channel.. Subscribed!
Hi Darren, thanks for the really comprehensive video. Do you know if it also works as a sound card with macosx?
Great video, I not sure if you have made video about it. But it would be nice if you can go over monitors, best beginner to advanced calibrated monitors to purchase.
Hi Darren, keep up the fantastic work. It has helped me immensely! I’m considering the UltraStudio 4K Mini. I use a Mac Studio to edit and grade. Would you recommend running my audio through the 4K Mini and then out to speakers/headphones (there are no XLR outputs on the Mini), or would it be better to continue to run my audio through my USB mixer, and then out to my XLR speakers/headphones? Essentially the Mini would then be to get only video to my color grading monitor.
Thank you for this explanation.
One question, when I set my Nvidia driver to “Override to reference mode” and output to 10-bit. Wil it not be the same? My Dell display has an internal LUT and is calibrated with i1Display Pro.
I don’t see the benefit for these cards in my situation.
I'd love a video on calibrating your monitor!
Hi Daren, I really appreciate your channel so much. thank you! I have 2 doubts if you can help me decide my i/o. I have a PC and I could put an 8k decklink to have 4:4:4 and Rec 2020, but I would lose mobility as a DIT. do you think Hypersdeck HD Plus would be a good one or the old UltraStudio 4k (thunderbolt 2)? I'm afraid of thunderbolt compatibility with windows thunderbolt 3, I can't find information. Thanks.
You do good work and make the world a better place. Keep on keeping on and thanks.
Thank you - thats really kind message - made my easter Sunday!
Good one Darren. I think this one is going to see a lot of links from the facebook forums. I have personally tried to explain this in a comment box, and it is not that easy to do. I will again be now linking to this for the explanation.
Given Newton's Law - every action has a reaction equal in magnitude and opposite in direction.
The thinking of people that it doesn't matter if their monitor is calibrated, because most people are using uncalibrated monitors, I usually point out that if your monitor is not calibrated, and it shows with too much blue ( common problem ) that you, as a colorist will look at it to make decisions, and push yellow into it to compensate the blue.
Which is what you said about cool or warm etc.
But the part that I add, is if the end user has a monitor that is uncalibrated and is already too yellow - all the yellow that you put into the grade is going to multiply and make that person see your video as a "screen of urine".
So the closer people are to the expected target, means that any direction that their monitor is off, will be the maximum it will be off, ( if the colourist display is calibrated). And will look as good as any pro video for color rendition.
Now I have to go watch your other one. Great job on this, explaining something that is confusing for a lot of people. The gamma part of it for Mac users alone is worth the investment. It is by far the most frequent question the Davinci Resolve User Group. Pretty much everyday. To anyone reading - the I-O box fixes this problem. The mac gamma issue is the OS not knowing or displaying incorrectly.
Thanks Darren.
Thank Jim as always. Good to hear from you and yes, that was kind of my point when I mention that it leaves here as best it can before it reaches "my dad's TV" where it could look anything...but it least it had the best chance from here!
Hope you are well.
Darren
Thanks for another great video. Correct me if im wrong but IO video cards are limited to standard video resolutions - so if im working on a sequence with 1:1 aspect ratio - or just any other composition resolution in AE for example - there will be no signal comming to the monitor from the IO device. - I work a lot on after effects and this has always been an issue for me - so I swiched back to working with Adobes mecury playback engine - that can show any resoluiton and aspect ratio.
Hi Aerial. Not true - I can display 1:1 on my external monitor via my Ultrastudio 4K Extreme 3. Im doing it right now just to be sure!
Hello,
I would like to ask you and would really appreciate it if you replied, I am a film editor and colourist and was wondering how can work I work remotely in live sessions with clients without the compromises of zoom's screen sharing since it does heavy compression on the image. I am asking you what is your solution for this because I have noticed that the quality of your streams is very good. Do you use the ultrastudio 4k for capturing or you are using something else, if so could I for example use the hdmi in port inputing the hdmi out signal of my reference monitor that is coming from davinci resolve and set it up in zoom as if it were a virtual camera so that the clients would have a better looking reference image through zoom or any other app ?
Hi Darren. Great video. Does this mean that an I/O device such as the BM UltraStudio Monitor also reduces the burden on the host machine, since it bypasses its GPU? Also, if one is monitoring in a 2K (QHD) display, does an I/O monitoring device still add a worthwhile advantage, even with the scaling problems associated? Thanks
Thanks Darren great video. Am I right in saying the clean feed is only available in the studio version?
Yes Martin. I really should have mentioned that - never thought about it!! Makes Studio worth it even more now!
Hey Darren, great content as usual! Do you have any tips on calibrating a broadcast monitor? Mine is looking great but the image on a standard rec709 monitor is too contrasted and saturated, yet everything is set up with Rec 709 Gamma 2.4 on both monitors as well as resolve. Thanks!
Appreciated Jay. I dont have any tutorials on calibration...one day!
Hello Darren, been learning tons from your videos. Thanks for always posting videos and giving pro tips. Just to confirm, you’re saying that using an IO device can help with Mac gamma shift issue as long as I have a hero monitor that is calibrated?
Been struggling with how Davinci shows one thing but then when I export the video off my Mac computer, it looks different.
if you are planning on uploading your video on youtube you need to use 709-A gamma and also do what the video says in 4:57 check the "Use Mac display color profiles for viewers"
Hi Darren! Is there a way to connect Sony A7III to this device and transfer my recorded video into PC? My goal is recording video from camera directly to my PC and then transfer this uncompressed file to the server.
Thank you!
Yes, but I dont know how. Speak to a reseller or Blackmagic please. Good luck
This is great! can you recommend some budget/mid-range and high end output monitors? (if you could recommend calibration software too that would be amazing)
Hi. I might do an episode on that soon, but without having them all here its very hard to be honest and I can only recommend what I use either here or in other facilities where I have worked. here we have Flanders DM250 OLED and Asus proArt UCG and Panasonic GZ2000. All great monitors.
@@DarrenMostyn many thanks
Hi Darren, i wanna make u a question . I use the "UltraStudioMonitor3G" for a clean signal. But my monitor does not have the ability to load 3D luts to calibrate it, it is a good Pro art 100% Rec709, but it does not have that capacity, maybe it is a slightly old model. And watching your videos, I came up with the idea of connecting a "Micro Converter BiDirectional SDI/HDMI 12G" or a "Mini Converter SDI to HDMI 6G" after the "UltraStudio3G", to use them as a LUTBOX and be able to calibrate my monitor, since these support LUTs. Because an AJA LUTBOX is very expensive and these converters are affordable. Do you think it's a good idea?, and more importantly, do you think it will work? Or if you can think of any other solution. Thank you very much Darren, excuse my bad english. My computer is an M1 just in case
Looking at the 4k ultra studio mini. If I want to have a client monitor in addition to my main monitor, can I use the IO device for two monitors at the same time (LG OLED for client, Asus PA32DC for my main). If so, can I also convert sdi to HDMI and still have HDR? Love the videos, been helping me a lot as I upgrade my office!
Thanks Darren, great video. Is your GUI monitor coming from the I/O or directly from the computer?
The gui cones direct from computer
Quick question about clean feed in Resolve! On, say, a MacBook Pro -- is the clean feed actually clean, or is it subject to ColorSync? I have the MacBook Pro 14" XDR. I can think of two scenarios:
1) External calibrated display (e.g., BenQ, ProArt, etc.) used as clean feed monitor via HDMI feed with laptop display (or another external display) being used to run the GUI. In this case, is the HDMI output getting managed by ColorSync, or is it in fact a true clean feed?
2) My current situation, which is a 27" non-calibrated monitor used to run the GUI and the clean feed being monitored on the MacBook Pro screen. The XDR Macs have "reference modes" built in (supposedly factory calibrated by Apple) including a BT.1886 preset. In this scenario, do you know if the "clean feed" going to the laptop display (set to BT.1886) is actually clean, or is the laptop display always managed by ColorSync?
I am also interested in this question
Hi Darren, how are you. I always like your videos. For my mac m1 I want to use an oled c-2 as my reference monitor. Which blackmagic io would be the ideal for 4K. I only need 2 monitors so the extreme would be an overkill.
Thanks for the explanation, Darren.
I was hoping you'd elaborate on what types of interference/inaccuracies the GPU/OS level processing introduces exactly?
And is the GPU-level signal necessarily inaccurate or just potentially? If I set things up correctly in the OS can I negate that or the IO box is absolutely the only way?
Thanks!
Hi Gleb. You can get it close enough to not worry too much, but it is simply not as accurate - thats it. Not sure how to say how much....too many GPU/OS permutations to consider but an IO box eliminates ALL those permutations.
@@DarrenMostyn Thanks for the reply! And you're right, there a whole bunch of variables, unfortunately.
Maybe an idea for some future content piece: how to set up your system correctly to avoid introducing unnecessary shifts. Maybe just the basics, to cover most common stuff.
While the advantages of the IO device are undeniable - I'm sure many still don't have one and would be happy to at least "get it close enough" until they do.
Also, I'm just curious about the science of it all :)
Anyway, thanks again.
@@DarrenMostyn Can you tell us exactly what permutations does a GPU perform? I'm a GPU Engineer and I've never encountered this. The signal you get out of the thunderbolt cable to the I/O device is a digital image that was calculated by the GPU.
@@FrancescoCarucci This is something that I've always wanted to see- to get the output signal from both an io device and a modern GPU (outputting at least a full 10bit signal) under a good set of scopes to see if there is actually deviation. Certainly years ago when signals were exclusively 8bit the case could be made against GPU video our accuracy, but the advice seems to have become de facto in colourist circles now without much hard scientific reasoning. Especially now that they are almost all capable of pushing a 12bit signal themselves if configured properly. 🤔
@@_burd I saw someone comparing both, and there is a slight difference, like the contrast etc. And for CZcams and other digital content, it is not a big difference, and totally fine to do it with GPU. Broadcast and film are different markets and need the IO output. I think calibrated monitor is more important.
wow i had no idea these existed or what they did but i like how you explained it in such away anyone can understand
Glad it helped my friend!
Great info. Thanks
Hello Darren, super useful video, as always! A quick question, what are the differences between the Deck link mini monitor and the mini 4K . The video files that i work with are, HD and UHD. Thank you in advance!
Mini monitor is HD only.
@@DarrenMostyn thank you so much for your time!
Good morning
I have the PC workstation in the same room where I have my old LG 65B6V OLED and I would like to use it as a large HDR monitor to check the preview.
For this I have been thinking of purchasing the DeckLink Mini Monitor 4K PCI card.
My question is:
Once I set "Color Managemet>Color Space & Trasnsform" the HDR rating, does the OLED display switch me to HDR?
Thank you?
Hi Darren, your video is the best information on the net about I/O devices. OI have one question about the Blackmagic Ultrastudio range; as I use an Atomos Sumo 19E for production on set, I would like to utilise it also as a reference monitor for my video editing with DVR. Since the Sumo has HDR capabilities, I wonder if the smallest Ultrastudio model, the little Monitor 3G, allows me to achieve HDR when connected with it. I understand that the 4K Mini or Extreme give more outputs and functionalities. However, as money matters, if the Monitor 3G box is sufficient for that purpose, it would be the best option for me. Thank you for helping and keep up with the great videos!!! Marco
The 3g small io does not support HDR over hdmi to the best of my knowledge. Its old hdmi spec. Pls check with bmd support.
Hey Darren, excelent work explaining this. I've been wondering for a long time if it was worth buying one IO device.
But now I wonder: if I color grade on a calibrated monitor connected to an IO to get the best color accuracy possible, when exporting with a GPU isn't it bad because the GPU might give inacurate colors? And why aren't graphic cards so color accurate as these IO devices?
I hope he elaborates on this a bit. If the GPU does throw the colors on export, what would be the point of having the IO accuracy? Maybe grading AND exporting via the gpu compounds the issue?
I dont think the gpu rendering will affect color at all. Because unlike gpu output to monitor, the rendering proress does not account for the system color management. For monitor that support hardware calibrating paired with 10bit output gpu, by disable or use an empty color profile in the os it should have the same quality as an io device.
Thank you for the great videos Darren. However I'm a bit confused.
Buying an I/O device gives you a better signal by bypassing the gpu and etc but you still need to buy a monitor that's at least pretty good at colour grading (and calibrated) to appreciate and make use of this better signal right?
Correct. No point without a calibrated monitor. But doesnt have to be expensive - i alwYs say get the best monitor you can afford for your business.
@@DarrenMostyn thank you Darren!
Hey ! Do you know where the "Window Outline" setting has been moved ? I can't find it under the "View" section. Thanks !
Thank u sir for sharing these valuable information ♥️
It's my pleasure Koushik! Thanks for watching my channel.
Hi Darren, great video as always!
I have a question related to a pipeline:
2 output devices from my deklink mini monitor 4K.
1. Eizo CG277 directly from HDMI
2.Panasonic Oled TV from SDI and a BM converter.
How can I have a calibrated pipeline?
Lut in the BMconverter and just calibrated Eizo is correct?
My problem is when I put a LUT in the output in the DR settings is automatically applied to all the output signals from the BM decklink.
I hope my question is clear enough.
Thanks in advance for your help!
Thanks Olmo. Yes, Out in BMConverter and calibrate EIZO internally on monitor is one way OR you would need a LUT in the monitor or a LUTBOX post the feed from the IO box and before your monitor. Hope that helps
@@DarrenMostyn Thank you very much Darren!
Thanks for this clear and useful video. I want to use Ipad pro m4 in Reference Mode with Resolve, either using resolve on the ipad looking at the viewer, using the ipad as an external monitor via clean feed, or feeding a calibrated display from the ipad’s thunderbolt connector is accurate enough for sdr grading to rec709? Or does the m4 gpu introduce the same issues that means it could not be regarded as being properly colour managed.
Okay, so looking into some decklink cards to put into my PC, there are a LOT of options. Since i'm not recording in my studio, I just use my workspace for editing coloring, I'm guessing I don't need a capture and playback card? Only a monitor card like Decklink Mini Monitor 4k? Is that correct? And this would still be useful if I'm transfering my recordings from my SD cards into my computer, and editing them resolve, correct? It's not for direct monitoring of a signal?
Hi Darren.... I have purchased an ultra studio 4k mini... I want to connect my Calibrated Monitor And My Projecter through ultra studio 4k Mini How to connect that.... Ple suggest me thank you
Would you not refer to your waveform & vector-scope as the main reference for proper colour balancing?
absolutely. Still helps to see it correctly too.
Finally got a ultrastudio 4K mini today! Running with a lg C3 OLED. Got the calibration coming tomorrow. (Mini grading surface). So going to get all set up with resolve studio on Mac Studio M2 Ultra. Got a 27” studio display and 27” retina iMac as dual monitor set up.
Now the question is: how do I set it all up?!!! And settings 😩
Hi Daren, thank you for the great content. I admit that I have been thinking about buying one of these devices for several days.
I can't grasp the difference. Does UltraStudio 4K Mini supports real-time H.265 encoding! So how does UltraStudio 4K Extreme 3 do?
What else does it have, apart from more ports?
I am also wondering if maybe "Teranex Mini SDI to HDMI 8K HDR" can do the same work for us like it's a converter but whether it will do the capture card work
not much difference except for the IO connections and physical form. Also 4K Extreme has PCIE connectivity aswell as thunderbolt 3. Watch this episode to see differences. czcams.com/video/5LU1x5qBS_Q/video.html
@@DarrenMostyn Many thanks, so I decided on the mini so far maybe in future will be upgraded
Thank you very much, Darren!
Q: If my clients EXCLUSIVELY deliver content to WEB, do I need an IO device?
Bonus Q: Is gamma 2.2 and sRGB ok for my timeline color setup in DR ? No broadcast or cinema delivery.
Hi. No-one NEEDS an IO but it will always give you best results. Yes gamma 2.2 or sRGB is good for delivery to web...but your monitor needs to be calibrated to that spec too. if your monitor is Gamma 2.4 then you can adjust that using colour management conversion. Hope that helps.
@@DarrenMostyn Yes, it helps. Thanks.
I had a DeckLink PCI card from BMD and the cooler from it was extremely noisy. I didn't see a difference from 10bit Nvidia DP output, so I drop the IO device. But you are right about clean video feed.
@@DarrenMostynI have an Asus ProArt PA278QV and a Mac Mini M1. The monitor can adjust gamma to 2.2 and 2.4, rec709 and srgb. I would like to ask in color management and monitor settings, what are the best settings for web delivery?
Yres those settings are correct for web delivery if your monitor is set to same. IO box still gives you the extra reassurance of colour accuracy even for 2.2/srgb
My guess is, you need to use an I/O device, to bypass the operating system's color management? Also because computers works with a color range from 0-255, while a TV works with 16-235?
So by using e.g. an Intensity Pro 4K, the signal goes directly from DR, via the PCI slot to the card, and out through the HDMI of the card.
But couldn't I just make a calibrated profile on my PC for my TV? The TV is already calibrated, and then use a software, like DisplayCAL, to calibrate the TV to the GPU and OS?
hello Darren , i hope you are doing well, my question is , can i use ultra studio monitor 4g with my mac mini?
Hi, on the last Eizo monitors it's possible to connect directly your computer via an usb c cable. Does it change something about the need to have an I/O Device for having the right color from Davinci ?
Hey Darren, is there any solution for getting vertical preview for 1080x1920 resolution in 3G SDI monitor?
Do you get any kind of performance improvement when using an I/o box like the
UltraStudio 4K Mini ? Does it take some load off the system ?
Hi Darren, the ATEM Mini Pro can work as IO device?
I’m considering picking up an UltraStudio 4k mini. I’ve used the decklink 4k and with that I could only get a signal when I’m in Resolve and have manually turned the connection on. It couldn’t be used for just Windows or other programs.
Is there a similar limitation with the Ultrastudio? I would LIKE to just use the one monitor for everything…I don’t necessarily need a clean feed monitor.
Wondering about this...do I need a BMD I/O? I am running a clean feed from my computer (Thunderbolt3 port) to an LG C1 monitor. Cheers Darren :)
If you're using Resolve, yes.
Thanks for this Video! I am already a subscriber :) I have a stupid question, i bought an (Ultrastudio Monitor 3G) but my Pc has no Thunderbolt connction! 😅 i totally forgot to check it. Can i make it works with a Displayport to Thunderbolt 3 Cable? or i have to buy a Thunderbolt 3 PCIe AIC?
Greetings from Vienna!
Not sure tbh. Check with Blackmagic Support. Sorry cant give honest advice.
Hi Darren. you did a video on the use of Oni scopes and mentioned you use a separate computer and monitor for you scopes. could you actually go in depth how you set up your scopes computer and scopes monitor .do you need a copy of davinci on your scopes computer and hooked up through your io device and how you sync DaVinci on the 2 computers etc. your help with this would be highly appreciated thanks buddy

Very interesting. Just discovered your channel. Just purchased Black Magic Resolve and from, initially Premiere. Just wondering about your pen graphics tablet. I have a Houin graphics monitor. Its only 2.5K and not 4K but would there be a way to use it like what your doing with yours? I mainly use it for anime figures for animations.
was hoping to do something in-depth on wacom but they wont get back to me despite tons of emails, calls etc and mine is over 10 years old! Will be featured in my MAY studio tour anyway!
@@DarrenMostyn Do you need them to do a segment?
Hi Darren. Love your videos. I just got Davinci Resolve Studio and UltraStudio 4k Mini. I really like UltraStudio 4k Mini but am suprised that there is no on off power switch. I found workaround by installing smart plugg and controlling the power through my iPhone. Do you ever turn yours off or you just leave it running all the time? Also if I turn it off and leave my windows PC on and I come back later and turn 4k mini on Desktop Video app will not detect it. I would need to reboot the PC in order to make it work again.
All my kit gets turned off. caring for the planet.
Hi, I am using the Ultra 4k Studio Mini with a Flanders Scientific. Everything looks greate when I am editing, but when I go to export it does not look the same. I am using a Mac computer and Red R3D footage. Can you tell me what I am doing wrong? Maybe export settings?
How can I use three monitors on Davinci. One will be clean feed. Second will be scopes and third will be color wheels. What I/0 device I need?
you dont need IO device for what you are trying to do but it will help. Clean feed needs a graphics card output NOT an IO device. Watch the video again knowing this. all the best, darren
Should I still check those two boxes, use Mac display color profile for viewers and 10 bit precision, when I have an IO box? I have an iMac Pro and for the most part it's been great for short films and for ad agency content, but I definitely want to upgrade, I'm looking at various monitors and the ultrastudio 4k mini. Just curious what the best settings in resolve would be for it if there's any small details about using it and setting it up!
No need to use it. Trust your monitor!
@@DarrenMostyn Sounds good, also another quick question, can I use multiple IO devices or can I use the same IO device for multiple monitors. In addition to the monitor I'm looking at purchasing I also have an OLED tv that I use as a client monitor for people to watch. Right now that's just via thunderbolt 3 to HDMI dongle, and video clean feed. Works great, but I need to have the Mac display color profile on. The solutions would be to either get another io device, I would just get the $130 HD version for the OLED and have the 4k version for my grading monitor. Or can I connect multiple monitors to the 4k mini, say HDMI and then sdi at the same time?
If I use the “clean feed” feature to feed a professional calibrated color grading monitor, what are the scopes in Resolve showing me? Wouldn’t they still be representing the viewer within the application interface?
scopes analysing RGB signal internally so not affected by clean feed as this is for output.
Thanks Darren - super helpful - one question: I'm going from a MacBook pro to an ultra studio 3G them from the 3G to an LG OLED TV via HDMI. I haven't found anywhere to set the Ultra studio to rec 709 - is there somewhere you need to do that or because the 3G cleans the signal that's a mute point? Thanks
yes. Use the VIDEO MONITOR section in project setitings.
@@DarrenMostyn Thanks Darren - in video monitoring it only has a REC 709 setting for SDI out.I'm HDMI out of the Ultrastudio - I went ahead and checked the 709 SDI check box in video monitoring and saw no difference so I'm guessing that when I set to REC 709 in my CST / ODT I'm in REC 709? Thanks for all your help with this!
Interesting… gunna need to look into this
no brainer!
I have recently got a Teranex mini SDI to HDMI 8K box upon recommendation.
I'm having an issue of getting a feed out via HDMI from X2 ports.
HDMI Port A works fine and I see a feed on my reference monitor.
HDMI Port B doesn't get a signal out which I have going to my Oled TV.
Can someone confirm if those HDMI ports can spit out feeds to different peripherals or does it work like SDI feeds that need to connect to a single unit? Which doesn't seem right.
Darren great video. I have one question. I'm about to buy the SW270C from Benq, and it says it has "Hardware calibration allows you to adjust the image processing chip in the monitor without changing the graphics card output data. Images remain consistent with original copies without being affected by graphic settings." does that mean that I wouldnt need this IO box? Or did I got it totally wrong? Than ks so much for your help!
IO box will still give more accuracy. Thank Bruno.
@@DarrenMostyn Thank you for the quick reply and advice! Can't wait to get grading with some proper monitoring (Im aware SW270 is the bottom line, but for sure will do an improvement over my outdated NT panel monitor!
Congratulations again for the channel, you are killing it with real data and content and as humble as a human can be. By far the best online!
So the short version would be if you want the best possible video feed for a calibrated monitor get an IO device?
absolutely!
How can you calibrate a monitor when bypassing the gpu, do I use ICC profile or what. Can I use regular computer monitor or do I need special one that is already calibrated. I'm using MacBook Pro with M1 and have the 3g ultra studio monitor.
I have external monitor BenQ PD2700. I was able to connect the monitor to the laptop through the ultra studio, but the part with calibration Im missing. On other channels poeple use DisplayCAL but there is no new version that run on Sonoma. Calman software is too expensive.
I'm very confused on this part.
Got a LG OLED C2 42‘‘ and it is not possible to calibrate it because the internal pattern generator does not work properly. Would cost a lot more to calibrate until they fix it. And a lot mir knowledge to do it correctly.
Interesting. Something to think on. Thank You.
Very welcome
Question: So the I/O device is just for monitoring? The connected monitor can not be used as a dual monitor right?
correct
@@DarrenMostyn thanks!
Hi Darren, great video!!! I know that you had mentioned in one of your post replies on CZcams that you get your pro monitor professionally calibrated. I was just wondering about the screen calibration process...would it not be important to rather calibrate the internal screen colour profile (the actual manufactures screen firmware ICC colour profile) as opposed to using a third party colorimeter for screen calibration as the ICC colourspace is saved in the OS software display driver for your graphics card. Because when when utilising a I/O device the video feed will bypass the GPU and calibrated ICC colourspace profile created by the third party calibrating software? Is this correct? Hopefully, I'm making sense in asking this question...
I wonder the same thing. If we're storing our calibration profile in the computer but the I/O tells the monitor to ignore the computer, what does calibration do?
@@HikingWithCooper calibrating the ICC profile has no effect on the IO box. If you're calibrating a reference monitor you need to calibrate it directly, not through your computer's operating system. A calibrated monitor will always be calibrated, no matter what device you plug it into.
@@christykail3314 thanks for the clarification - makes perfect sense that the I/O device would bypass the computer OS color profile altogether, otherwise it would defeat the purpose of utilizing the I/O device in the first place, and that a calibrated monitor would need to have a built-in hardware calibration setup for an accurate color display.
What are your thoughts on the connecting the Declink Card to a (newish) OLED 4K TV ?
This is a common practice. Some OLEDs (i.e. LG C1, 2, 3) apparently have built-in color bars so you can calibrate it correctly.
Hey Darren ... maybe you heard this question a mot, but is there an alternative, because i have no Thunderbolt on my PC and i want a device like UltraStudio 4K, no cards. Thanks for a short info. Blessings.
Yes they do deckling PCI cards. Same performance just on a PCI card. Enjoy!
will the io device also influence the interface video viewer ? or just the second monitor full screen video?
Other question would be if the monitor can be calibrated via a external calibration device like spyder etc. Or does the monitor need to be already calibrated out of the box?
IO is just for HERO monitor, not GUI. Monitor can be calibrated by any software and tools you choose. Hope that helps. IT IS Indepenendent of GUI with an IO which IS best.
@@DarrenMostyn But if the Hero Full screen monitor needs to be connected to the pc to run the spyder calibration software (in order to have accurate colours) How can you still connect a second hdmi to it? 😅 hope my question makes sense
You are the best at this.
Thanks Nali. Trying my best. Enjoy the rest of the channel! Darren
Can you use the deck link HD monitor or the deck link 4K monitor, it’s a simple PCIE card with two outputs, HDMI and SDI.
yes
@@DarrenMostyn Thanks!
Awesome & Thanks :)
Great Video
Coming from a retouching background I fully appreciate the importance of a hiq color pipeline
I EXCLUSIVELY deliver content to Web
So, whats your take on that?
Ill use my Eizo Cg's set to rec709 or sRGB
GUI or cleanfeed and do a reality check with a 3rd pipe to a tablet via USB feed
It works ok
Also, I never understood why you would monitor with rec709 gamma when delivery is sRGB?
Maybe a Video about grading for web;)?
Love your videos :))
Same situation for me, Michael. I use an EIZO CG248 4K monitor st to sRGB an gamma 2.2. Gamma 2.4 is too dark for web content. I hope Darren will ask our questions
Even at Gamma 2.2 the video signal from an IO will be better because the feed is more accurate. if your calibrated 2.2 and feed it true signal is going to better than looking from GUI or GPU "Clean feed" You can get very accurate if you know how to set it up well and test your workflows thoroughly. Hope that helps. And thanks for the kind words!! Appreciated.
@@DarrenMostyn I’m trying to understand for a long time if it makes sense of buying I/O box for mac. As we always deal with gamma and saturation shift when using gamma 2.4 for export because of tag 1.2.1. And when we use rec709-A export looks exactly the same as viewer (gamma tag 1.1.1). I haven’t got any clear answer from blackmagic, maybe you can help me…
Are you bypassing the GPU or the OS color management (Apple's Color Sync)? If you're bypassing the GPU you would take a significant performance hit. Even worst that all these devices only offer 1080p, 2k and 4k which are all not optimized for Mac's scaling. There is a very visible latency for example if you're working on a 4k monitor directly connected to a Mac, and I can't imagine a dongle is going to alleviate that. Usually for OSX you're better off running 2.5k or 5k to optimize responsiveness and sharpness but it doesn't seem any of those BM products support those resolutions. Would you be able to clarify on this?
Maybe this is the case - there is noticeable lag between your laptop and your displays at the end when you see the wide shot in the video demonstrating the power window.
would you now use the blackmagic media player 10g?
My big "problem" if we want to call it that is that unfortunately even top end Extreme's only have a single HDMI output. So if you want multiple monitors to go through the I/O interface, then you'd have to buy multiple interfaces.
The only "other" way is to try and find grading monitors that have SDI. Unfortunately I have found ZERO grading monitors that cost less than $5000 that even have an SDI connection. The other displays people are using in place of a "true grading monitor" like the LG C2, or ASUS ProArt series (PA32UCG-K) or LG (27EP950-B), more or less all LG display in general, Benq, etc also don't have SDI. Even $2000 Eizo monitors don't have SDI (you must spend $30,000 for that feature on the CG3146). And bottom end monitors from FSI don't make sense. (Also Apple's own monitors can't even be considered because they can't be image managed with their Thunderbolt only connections).
Is there something here I'm not seeing? What SDI monitors exist that don't cost more than my camera that I can use to grade with? Or are there SDI to DP/HDMI converters that won't mess with the signal that are also viable options?
Hello! I've been researching this same topic to no avail. Have you found any solutions? Thanks!
Blackmagic do cheap SDI to HDMI converters, or you can use little HDMI splitters.
Speaking of calibration. As an amateur/beginner I looked into calibrating my Apple Studio Display. I don't have the colour checker device that floats over your display to take measurements. After discovering that these can cost $A260 to $600 I wondered if these cheaper devices are any good? The Spectroradiometer from Photo Research Inc is $US14,000. Do people do display calibration for a fee?
Yes you can get a pro in to do it for you. they will usuallly have a more expensive probe and a good understanding of how to do it.
If the color is rendered using the GPU in the final export, wouldn't it be more accurate to grade using your GPU? That way you would see exactly what you're exporting?
The GPU is only used for math in that case, so it's just doing calculations and writing 0's and 1's without needing to output an image on a screen. When it does show an image on the UI, you add the OS layer to the signal and that's where it starts to change the look. In which case the GPU preview would only be accurate if you would be watching the video on computers with the exact same specs as yours (and even things like apps and GPU driver version might play a role here).
No. It is explained in this episode.....CS Color has got it right. The GPU feed is different to what the GPU is processing essentially. Hope that helps. Maybe watch the episode again with this information. All the best.
Thanks CS Color stepping in...overwhelmed with questions on these two videos!! Appreciated.
Hi Darren, if i calibrate the monitor whith an ICC profile whithout ultrastudio?, work similar? This ICC profile would not be compensating what the video card gives me?
Better than not claibrating for sure.
Could you clear up for me Darren how is the cable from the computer not using the GPU to send/draw out a video signal to an IO box ? Is there a way the operation system can feed out video signal without the GPU being involved ?
the feed to Io box is true signal via cable- the feed via clean feed is a cable too but via the mac. Cable is nothing to do with it.
Hi Darren, quick question. Can I still use an I/O device even if I only use 1 monitor or does it have to be at least 2?
works with one monitor - thats how I use it
Modern NVIDIA cards can output 10 bpc full RGB signals without YcbCr compression. Wouldn't this be extremely close if not similar to a video signal from the Blackmagic IO device?
yes very likely and the fact you take MAC OS out of the equation. But still not technically as accurate.
@@DarrenMostyn that's fair, but for me it will be plenty as long as I do colorgrading as an extra with editing jobs
@@mantenbrink all good until its your main business i think
Darren, I've got a PA32UCX-PK and an Ultrastudio mini 4k. I've got things set to 709 2.4, but the black levels appear to be lifed, when I view on an iPad or export, there is so much more contrast. Any guidance here would be amazing. Thanks.
it sounds like it needs calibrating and check your resolve output not set to default which is REC 709 Scene
check it with colour bars from the generator too
So it’s used to color correct properly? I just inherited a 4k extreme but idk what to use it for ! Lol
Hello Darren! 😀 I have the intention of using an LG C3 as my main and only desktop monitor. I've calibrate it in Filmmaker Mode… But now, when I connect the Mac to the IO device, and this one to the LG, I only see the Resolve image in Full Screen, and not the user interface and all the controls… And I've tried to arrange it in the Workspace Menu, but I couldn't. Any advice?
(*Thanks for all your priceless help 💕💕)
the IO is there to bypass the GUI. You wont see anything but video output, no interface. To see the interface connect a monitor to your mac and then you'll see both side by side, 1 GUI and 1 FULL video signal output. Hope that helps.
@@DarrenMostyn so if I just want to have 1 screen in my desk, having the LG previously calibrated, can I connect it directly to the Mac Studio (without any IO), and still have the colors calibrated, or the software will mess it up…? 😕
@@mitchelpou If you don't use the I/O, you're seeing what your gpu is sending out and not a clean signal.
Can you live grade in resolve using an I/O device
If you enable "Use Mac display color profiles for viewers" wouldn't that nullify the correct calibration of whatever the external monitor is calibrated to? E.g. if my viewer monitor is calibrated to Rec. 709 and I enable this option, I'll be seeing Mac's colour profile on top of this instead right? So I'd be colour correcting for the Mac's ICC instead of my intended colour space am I correct?
Getting a new monitor soon so just want to make sure I fully understand how to make the most out of it!
Still best option is via card output. Watch the video again if needed to be sure and then you’ll get good results. No shortcut, just solid advice! Watching back in QT on mac etc always an issue. There is NO real fix - dont watch bad youtube advice! IO device gives you a true view on a calibrated display.
@@DarrenMostyn Thank you for your reply! I know I really need the Ultrastudio 4k Mini to give me a true signal I want; definitely worth every penny but it'll just be a while until I can save up and get my hands on one.
Depends which type of calibration you used. If you used software calibration like Spyder or i1's calibration program, they generate an ICC profile and install it to your mac. If this is the case, by turning on the use mac display profile option, resolve will use that color profile and display correct color. If you used the monitor hardware calibration software, such as LG or Benq, they store the calibration lut inside your monitor, but they still install an empty place holder ICC profile in your mac OS, in this case you dont have to enable this option in resolve, but it also shouldn't cause any problem since the color profile in the mac os should only be a placeholder.
@DarrenMostyn I just got a used one from Ebay, can I replace my Scarlett 2i2 device with this? as I see it also has audio I/O. Thx
no idea! It will work as an audio interface - no idea what your scarlett 2i2 is doing
Hey man! I’m currently considering buying this thing.
One question tho:
How much does it actually speed up your GPU? Since the GPU doesn’t have to send the signal to the monitor. Is the difference noticeable?
Thanks!
It wont speed up your GPU at all. Not sure where you heard it would do ? You may be thinking of the e-GPU ?
@@DarrenMostyn Hmm. Somehow I have the impression that since the video signal isn't processed by the GPU, the GPU has slightly more processing power available since it doesn't have to send the signal to the monitor. Also, a Blackmagic retailer here in Finland told me that it indeed allows your GPU to run faster. Is this not the case?
@@muskettisoturi A GPU has several processing cores on the card. The big chip on there does all the heavy graphics processing work on your computer, but there are separate chips for encoding/decoding of video and input/output dividing. Especially newer/high end GPU's have this as separated chips and they will not slow each other down. If you have a low-range GPU it might be that the big chip does everything, thus slowing down because of more screens. In general, modern cards will not slow down noticeably. (Sidenote: unless you connect 3-4 8K displays or something like that. These smaller chips can handle pretty standard stuff, but everything going massively overboard will impact the performance of the whole card of course.)
Is a calibrated monitor a special type of monitor? Or just gets some adjustments?
it is a specific monitor that CAN be adjusted to a good tolerance level and measured.
Hey Darren! I’ve got some questions. I made some investments into a new FX30 camera, DJI Mini 3 Pro, PC I9-12900k and LG monitor so I can do everything in 10 bit 4k. I really want to up my game this year so I dropped some cash ha I spent hours trying to make sure I get everything that will work well, and obviously better than what I have now but that’s within my budget.
The monitor I got is an LG 32” 4K Ultrafine IPS 32UP83A-W which comes calibrated but I bought a calibrator from Spyder. The monitor has hardware calibration but I don’t know how I would go about doing that. Also to my understanding my NVidia 3060Ti can output 10 bit with an update.
SOOOO can you perhaps help out with how I could go about calibrating a monitor like this and using the clean feed feature? Would it be worth doing it through the Spyder software and GPU or should I only do a hardware calibration or do I NEED to get an IO, and what IO would I even use in my situation, budget is running thin at this point lmfao
Help? 🤷🏻♂️
This stuff has gotten a little confusing on what to do to get the best out of what I’ve built lol
Definally use the monitor hardware calibration, since Windows does not support global color management, and Resolve also does not support windows color management, so using ICC profile from the Spyder software will not affect Resolve. By doing hardware calibration, it will correct your color in every application including resolve. The LG hardware calibration softeare still install an ICC profile to windows, but that is pretty much an empty placeholder profile, the actual calibration lut is stored in the monitor.
The hardware calibration software is called LG calibration studio, you need to connect the USB cable between your monitor and PC, and you can plug the calibrator to any usb ports on the monitor or PC. For SDR video, you can just choose the rec709 with gamma 2.4. Brightness depends on your ambiant light, usually around 120nits.
Hey, if im not using an I/O card and i want to use dual displays can i set the DaVinci Resolve to send the video feed in HDR to my second display and the interface to be displayed on my laptop's display in SDR or if i want to grade in HDR i need both of my displays to be HDR capable? Thanks!
no. you need to be using dolby for HDR and sdr simultaneous
@@DarrenMostyn Dolby? What Dolby? I think you misunderstood me or im not getting something. I mean cann davinci resolve send a HDR signal to the display where the video feed is and an SDR signal to the display where the interface is? Is it possible without an IO card or i need a Decklink card?
Thank you!
