Great way to prevent these issues is to simply stop shooting in S-Log3 in 8-bit
Then slog2?
@@rishyachanda5805 same. One can try to use external recording to counter 8 bit XAVC compression banding especially in gradient/flat areas but it is so messy heavy and help a bit but not enough.
@@rishyachanda5805 Better if you have situations with high dynamic range, but under controlled circumstances, or maybe an overcast day outside, HLG works great
@rishyachanda5805 im shooting with 4:0:0 8bit footage.
I found that HLG 3 with bt.2020 works perfect for grading. obviously you cant push it too the max. But if you expose correct and use certain tricks in resolve, i almost never get banding
@@DrummerTSherry The problem with HLG3 is their is not a direct CST transform for it. You can get it close but at the end of the day it'll be guess work.
I found that transcoding h.264 to prores reduces the blockyness(?) which shows up when picking and altering certain color. I used this technique every time I edit 8 bit footages.
I also watched your previous 8 bit editing videos in the past, because I only had cameras that shoot videos in 8 bit. They helped me a lot!! Good to see you updating 8 bit tips up to these days.
Thank you, those are great tips! I have been using the "common" selector tool to separate the sky, and applying "Color compressor" to the sky to get rid of the banding. But I'm bringing your tips into my workflow and there are cases where on tool works better than another. And you still can combine both.
Thanks Qazi. You continue to teach me new things about DaVincini Resolve and give me confidence in my videos when in 8 bit!
Happy to help bro
I’ll never stop leaning from you. You are my mentor. Thanks a lot.
LFG 🔥
As a professional editor for over 15 years, you made me fall in love (no bs) with color grading. Can't wait for this toolkit (can we beta test it?), and a LUT is always welcome obviously 🥰
Much love bro. There will be a free demo with no expiration.
Videos like this highlight just how bad CZcams compression is. I can imagine the night and day difference you're seeing but it's not that clear here on CZcams. They really need to do something about it. In comparrison Vimeo always looks great. I did consider turning this video into a drinking game. Take a shot every time Qazi says it's CZcams compression 🤣
I can see it but maybe it's a Premium issue.
Hahaha. Lots of people will get hammered.
I saw it
Great tip and also thanks for the LUT. If the rest of the Toolkit is on the same level as that LUT, sign me up! Pretty impressive what it does to the skin tones and color separation.
Glad you're enjoying the LUT but it's not even scratching the surface. You'll love QT
Great tutorial. I'm very curious about QT... Could be EXACTLY what I have been looking for.
This seems clutch. What I usually do is a very broad stroak with a qualifier, only using 1 or 2 channels max, to the portion of my video with a banding issue. Then sometimes, a tracked power window as well. It works great for banding issues with the sky and not that intensive on my system. There are definitely scenarios where this approach doesn't work, but depth mapping seems like a great alternative.
thank you for always sharing new techniques for us to get better. Please will love to sample this lut on my 8 bit footage as well, if possible.

Would love to work with the LUT. Longtime admirer of your work. I always learn much from your videos.

I am encountering issues with color accuracy during the color grading and rendering process of my project. When I color grade and render in an uncompressed format like ProRes 444, and deliver it to the client or import it into editing software such as Premiere Pro, I notice discrepancies in luminance or contrast values within the editing software. These differences persist even after rendering the final output. If there are specific settings or steps required to ensure accurate color representation post the grading process, I would greatly appreciate your guidance.
Been learning color grading from this man since day one... this is CRAZY! Thanks Bro!

Much love bro. ♥️
Could you increase contrast with an additional node towards the end of the node tree so that we can clearly see the banding vs. no banding in future videos?
Wow, thank you so much for sharing this video! I use to have huge banding issues when filming the sky on my Sony A73 8-bit 4:2:0, now I use an A74 with 10-bit 4:2:2! YOU ARE AWESOME!!!!
10 bit is a non negotiable for me and ty for the love bro.
why did you adjust the gain in LINEAR ? what is the difference between linear and 'use time-line' ?
yes bro ! you make my day, banding always annoying me I was using masking ang blurring, but this of course much better
Can you do a video on color noise/pixelling next?
If i use 10bit video and then render it to 8bit for youtube video, is the color banding not visible?
The QAZMAN's back with a bannger! It'll help a lot for GoPro as well
Also, throw the LUT if you can. I'm here to catch it😁
Always love hearing from you brother. Lfg 🔥
How to get the best quality footage from a7iii generation cameras:
Choose either the slog2 or slog3 profile. Change colour mode itu709 matrix.
This will give you good colour to grade in the post!
Happy shooting!
When given the choice always choose slog3 over slog2. Slog2 is much harder to grade. Slog3 was built off of logC.
I don't understand when you have an HDR monitor or even the Sony VR glasses you see bands, it always bothers me, because that means that there is compression somewhere and that what you see is no longer 10bits
its a good idea to have a free trail for the Qazi toolkit the same as dehancer tool
thanks for the video, I think that depth map is for paid davinci right?
your viewer from Oman sony zv e10 s-log 3 shooter
Can we get Hollywood range colours to our theatre film using benqpd2706u hdr10 wide colour gamut srgb95% 4k monitor along side lg CD hdr oled tv as secondary display pls say
It's hard to explain about differents in 4:2:2 and 10 bits when it looks the same on CZcams
There is clear banding in all your examples where banding is supposedly absent. If CZcams spoils the video anyway and returns banding, then why all these manipulations?
Me too. I saw no difference on a 4k HDR monitor (not saying that this video is in HDR format). I would think that adding thicker grain would be one of the better solutions for banding.
Because these projects are not for youtube, just the tutorial.
Unfortunately, I have this problem with the 10-bit Canon C70 C-log. As a newbie, I suffered the learning process with my first feature film. Usually, the worst was with indoor shoots. I tried to change camera settings, lights, etc, but nothing worked, so I thought my gear was faulty. As it came, some extra like chromatic aberration? and noise, I began to use noise reduction as the first node, then deband with masks as the second, after I did the CSTs. I am not a technical person, so I find it very painful to learn 😂😂 I will try this, if it works better. I put my heart and money into this film; I want it as good as possible. Thank you for sharing it with us, Have a lovely evening.
It can be very frustrating. Good luck. ♥️
@theqazman Thank you. It is, but I won't give up, so one day, I will know what I did wrong 🤣.
Bro
Can you put out the extraction look ?
Thanks for the amazing video but
Can u please explain all about nodes for beginners??there is no such good video for understanding nodes in CZcams plz..u r amazing brother❤❤
Check the description of this video he has a free webinar where he tells all about it.
Video on that drops next week.
wow, can't wait for the QT :)
Hey, Can I have the LUT by any chance? I am having real issues with banding in slog2 and slog3 both, thanks for the tutorial it's working good for me but not cleaning up the whole banding, got the footage better by 60-70%

8bit like another videos from this channel talk about like 8bit! the subject never dies!
GREAT.. as usual..
I'd love to know more about the QT Lut!

BlessUp bro❤
8bit is fine with a less flat format like standard. Slog requires too much pushing to make it look normal
Hey dude, Have you ever graded Z cam footage? there is no colour input space for the camera but would be good to see you have a go at z cam. I have a z cam if you want me to send you some footage. Raw pro res
I have a while back. You should look it up on my channel.
@@theqazman I cant find it dude, do you have a link?
1:40 but why the A7IV and A7III shoot different 8 bit footage. Both 4:2:0 8 bit 100mbit 4K and the A7IV has way less banding :). My theory - the 10bit camera is processing better the footage and it is smoother even if it is saving it in 8bit 4:2:0.
I saw somewhere that if you scale down 4k 4:2:0 footage to 1080p, you get 4:4:4 color. Is that true?
When you downscale a 4K video with 4:2:0 chroma subsampling to 1080p, you don't get 4:4:4 chroma subsampling. Here's why:
In chroma subsampling, the numbers represent the ratio of luminance (brightness) to chroma (color) samples. The first number refers to the number of luminance samples, while the second and third numbers refer to the chroma samples.
- **4:4:4** means each pixel has its own color information: 4 luminance samples and 4 chroma samples.
- **4:2:0** means the color information is reduced: 4 luminance samples, but only 2 chroma samples horizontally and none vertically.
When you downscale a 4K 4:2:0 video to 1080p, the resolution decreases, but the way the color data is stored (chroma subsampling) remains the same. You still have fewer color samples compared to brightness samples. To get true 4:4:4, the original video must be in 4:4:4 format, as downscaling can't create additional color information that wasn't there initially.
@@primermag Ok thanks for the explanation 👍
Quazi brother I need the lut. ❤️

That's actually a nice lut.
hi bro how to get the LUT?
for Sony slog 2 thx bro

Спасибо мужик. Это как раз то, что мне было недавно нужно. Ты вовремя!
When you said "no banding" at around the 2:00 mark, it looked horrendous. Like you said, probably just YT compression, but just wanted to ensure solid feedback.
My coach. I need the lut too

Both are log profile?
Yes
Do you know same trick in Premiere?
if you have a similar plug-in in Premier, then yes, similar rules will apply
I just change ur like number 786 to 787 superb change in clip
Thanks Brother

I just throw grain on it. Done in no time. :)
That works most of the tbh
Please send me to tool

Cool fix but I’d rather my clients just stop sending me 8bit and upgrade their cameras, they have the money. One of my clients used to send me immaculate stuff and for whatever reason they downgraded and now it’s all rubbish for the last year 😭😭
they send 8 bit footage they get 8 bit worth of grading quality as simple as that😹
@@biswajit07 haha exactly.
Watching this video at 360p 😢
if a creator is shooting 8-bit 4:2:0 or 4:2:2 and youtube's compression is going to destroy the footage anyway, why bother ever uploading to youtube? it seems like the full solution for shooting 8-bit is to take your advice AND to upload exclusively on other platforms.
I have proof that 8 bit doesn't suck if you know how to color grade
Share your knowledge!
@@MCplayer94 in this case you somehow mask banding in post, but it is anyways already there when you record 8 bit.
@@gustavevilleneuvedehoff-un5459 I didnt mask anything just graded normally
First here🙌🏾🙌🏾🔥🔥
Secound here
That ProRes footage that those clients want looks like crap because it's 4:2:2
