Enjoy guys :) and yes that IS me singing at the end of the video!
Harv Video/Audio Stuff Wonderful video Harv. I absolutely love your style.
Hiya, I can't find your song anywhere. Could I get a link please?
Hey please give me cinematic luts sony a7iii for film
Great voice!
Thanks.. i learnt a log... i mean lot 😁
😂😂
Excellent video! I have already purchased the Phantom Arri LUTs with your code and they are amazing! In post I have very little to change. It is only recently that I leant how to expose correctly in S-Log2 using histogram and zebras which makes all the difference. Shooting outdoors I also use a Hoya ND8 filter which again helps if in bright sunlight. Keep up the good work and looking forward to your low light video.
*_simple and humble explanation- 100% quality_*
So basically Logs are like Raw photos. Both retain a lot of information from the video and photos to where you can bring back most of what the original lighting and colors. That or do more with them during post.
This was also my way of thinking about it, until I found out you can also shoot video in RAW. Each frame is a RAW file, so video file sizes get HUGE. Shooting log is sort of an in-between jpeg and RAW. At least that is how it was explained to me.
This was a very understandable explanation of a term that people often use, but never explain.
Had no idea what the whole log-thing meant before, very well explained man thanks a million!
You’re very welcome 👍🏻
I read "what is log?" And my mind immediately "baby don't hurt me! Don't hurt me!" 😅......... excellent video! 😊
Using V-LOG L the first time it was an amazing experience for me I will never miss! My older cameras doesn't support LOG-mode, so it was an eye opener to me. Thanks for your channel and your calming style...👍
Just watched two of your videos and I definitely have to watch all of the others too. :D Great knowledge, great realization of the videos and very positive person. Greets from Germany.
What is log?
Baby don't hurt me, don't hurt me... no more.
Fuck to late
Thinking the sameee
hahahaha good one!!
Fuuuuck...i pressed on this video just to comment that...and i came here just to see it on top and get dissapointed...but i am glad about your humor😂
concise and to the point, very helpful, love the video!
I just learnt about Log today thank you for the great video.
really good stuff - thank you i learnt a lot
Thank you. It took me a long time to find a video defining and describing these acronyms. Please more for beginners
Many thanks! More to come 👍🏻
Such an amazing video! Learnt so much in one, can't wait to watch the colour grade vids :D!!!
Me serching for 'log math' video and end up watching this : 👁️👄👁️
Good.
It's really straightforward to understand what you were conveying. By presenting different kinds of profiles and making comparisons, you help us get a thorough understanding of slog. Beautiful job!!💯💕
Glad it was helpful!
Very early on in my film career I simply used to just adjust the contrast, and sharpness by lowering them and save the setting to use again, it gives you the same effect as an official log format which does the same thing.
I went on a search to learn more about my a7rii and discovered your channel. I'm learning so much! Thanks man!
And now you really wish you waited till a7iii S
This was soooooo helpful. Thank you 😃
Yet another awesome video by Harv the man. Thanks a lot :-)
Do you have to deal with your white balance when using luts and how about the light temperature of artificial light?
Thx. Really concise and clear info here. Much appreciated
Many thanks 🙏🏻
Best explanation and example I have seen wow!!!! I need to make these changes. I always have issues with my highlights/shadows
Side by side there is an obvious difference. I prefer the log, more detailed, more cinematic! This will change my videos and image quality! Thank you
Perfectly explained, brilliantly pictured, thanks a lot :)
Very helpful info. Thank you!
Thanks for the information specially, about luts.. Big thanks👏
Thanks for your efforts and collection of Good informations. 👍👍
Your explanation is the best that I’ve watched. Most I’ve watched have my mouth open and a confused look on my face, lol!
thank you for your clear explanation
This was awesome, thank you!
Thanks i was always wondering bout it😊
Great video mate, thanks. Also, noticed Bristol at the start. Boy do I miss that city.
My home, I love it too 👍🏻
Thanks Harv!!
A very informative video!
great job man, good video!
it can get a little confusing but glad you lay it down
clearly explaint.. thanks bro...
now everything makes sense now. thanks!
I think i can simplify this: log is useful whenever the internal camera picture profiles aren't working for you or your style. If you have the option to create a custom profile and use that, it's better. Log is a last resort suitable for people with a good amount of experience with messing with luma curves
super good explanation, than you so much!! :)
Woaw found such great video, thanks a lots.
Great vid buddy
So cool! Thanks 😊
omg ty ty ty!! This was a great explanation:)
You’re welcome 👍🏻
Video is so informative
Harv, did you shoot this internally or externally? If internally, I think you should do another test using the workaround to get the true log curve in camera.
Nicely done! Even though I'm a Canon guy, you were generic enough for any shooter to grasp the inherent flexibility of log.
good education video..thanks brother
Thanks for the info - I didn’t know what the log is . But what the the difference among all types of logs mentioned.
thanks! how do other aspects affect use of Log - like 10bit vs 8bit and 4:2:0 or 4:2:2?
Great vid mate, thanks!
You’re welcome 👍🏻
thank you somuch BRO.
Thank you!
I wish I knew this video 2 years ago haha but thanks a lot for the stuff! vv easy to understand! vvv helpful!
Woow , thanks for that ❤️
Very useful, thanks. Q: what do you use for editing/processing vlog?
Great stuff! Harv, Do you recommend slog profiles when shooting in low light situations?
It’s funny you should ask, I have a video coming on this very topic
@@HarvVideoAudioStuff where?
Amazing!
Thanks!
nice video and codenames is an awesome board game man :)
Yes! Love that game 😝
I'm a little late... worked in film and retouching for a long time. Worked as a color lab printer for 15 years, printing all kinds of commercial work. The problem with that is I still dream about working in the lab with those four Chromega enlargers, and those beaten down easels that should have all been dumped. Made a short noir when the 5D Mark II came out, shot some cool Robbin Ford, Pat Martino and Dave Liebman footage, all on youtube, and no matter what you can say about tech, it's about waking up with an idea in your head. If you go back to the late 1920's early 1930's, they already had figured out how to combine film stock, lenses, filters, (those now impossible to find rare gauze filters made from french women's stockings) and lighting to make us notice what they wanted us to notice, and do it perfectly. We watched the eyes. We didn't find ourselves staring at some odd little bump or defect, wondering well, if Carol Lombard had that and got away with it....when digital first pretended to be worthy, everything was in focus. That's fine for an R.E.I. ski video, but not for telling a story. Your eye was not directed. I figured out a way to shoot a night scene using only available street light. I shot a plate of the scene, and layered that over the film, except for the actor's area. It eliminated 90% of the noise in the shadows. Here's my short noir, Bum Rap, on the imdb web site. These imdb films seem to take about 4 seconds to start. www.imdb.com/video/vi976727833
Thanks for this tip ^_^
Help! As a noobie here, I'm trying to find out if LOG is an industry standard setting across all video makers or... is it different for each company? AND... it seems LOG is basically a 'pre-set' similar to an EQ as in music production? (I have more of an audio background.). Thanks in advance!
Could you please make LUTS for premiere?
What's an external recorder? Thanks, thanks, thanks
Do log footage take up more space in the memory cards?
Nice
The best way to use log is to change your color space from log to, lets say, rec 709 o wathever is your color space. LUTs are destructive if you can't use it properly, but changing your color space directly means that you can really tweak everything without fear.
No, that is not how it works :) Also this video tell a different story
@@CSMoviePhoto i literally do it every single day, cause log has a non linear color space that need to be transformed to linear color space. You can edit log without a color space transform, but it will be way harder.
@@Danimally You can't use log with Rec709. LUT are not destructive in any way. You simply can't change color space from a low color space to a large one in post so you can't use a low color space with a log. LUT affect not only the dynamic light curve but colors too. It is not a simply way or explanation on gamma and LUT.
@@CSMoviePhoto go yo davinci and try. LUTs are destructive if you cant use them properly, if you use them right there's no problem. You can certainly use a LOG file with Rec709 if you transform the color space (that's what ACES workflow roughly do). I'm just using Rec709 as an example of color space, not of the best(tm) color space. Point is that a logarithmic curve file will look awful over a EDL with a linear output, and will need a lot of color grading work... or you can just simply transform the color space from your log file to your output color space and work from there
@@Danimally you simply don't get to right point. Here is from Sony, and is under a DaVinci Resolve pic: "Shoot in a wide colour gamut Normal video footage is shot in the REC.709 colour gamut, but material recorded in S-Log is recorded in the much wider S-Gamut colour space. Put simply, the wider the colour gamut, the more colour information can be recorded and the more vibrant and realistic your images will look.More information, more control
S-Log captures far more information than standard REC.709 footage can record, giving you more control over the finished image in post-production. Instead of exposing for highlights or shadows when shooting, you can capture all of this information and choose how you want to display it later."
3:15 you look like Tony Stark in the right two images... lol
thank you for the simple and short explanation!
Ha ha I'll take that :) could be much worse!
I like the "Drive"
Can you please tell me if I shoot with only 3200k tungsten in log profile will it be ok ?
Can you make a vid of how to transfer raw c log vids from your camera to your pc every time i try to download the vids it won’t let me can you help me out
Short answer: baby don't hurt me, don't hurt me, no more.
Where can I get the song :'(?
Does LOG use a lot more storage due to the amount of picture information it stores?
Nope, it’s exactly the same 👍🏻
What is a lookup table?
Sony log cine ie or 100 iso on a bright day outside???
Love from india
Can the camera autocorrect the recorded log footage? So I dont have to do any editing?
That's literally the point of using Log, editing yourself. You can use the standard camera modes to get autocorrect!
I have 4k log video shooting option with manual control on my phone 😇 obviously my phone can never compete professional cameras but still having such feature is kinda blessing.
It's log, it's log, it's better than bad, it's good!
Hey Harv ! What about the profile of your model ??? 😋
That’s Amy. Check my other videos, you’ll see I’ve done music vids for her in the past 👍🏻
@@HarvVideoAudioStuff James Harvey, I'd rather watch your music videos with Amy or on the LOG for colorists than Amy-Jayne Batt's Vlog ... What did she do with her voice ? Her voice is the product she has to sell, not beauty products 🤥Now other than that thanks for your tutos and I wish u an amy Chrismtas 😀🍷🍷
What is the difference between s-log and j-log?
0:13 What is log? Baby don't hurt me, don't hurt me no more
Are LUTS presets?
I hate when they try to sell to you luts instead learning you how to make your own
Harv, would you please look at the video from about 7:08 through 7:42. Your mouth movement in the video does not match the audio as you were talking. This, of course, does not detract from your outstanding explanation of log.
its a bug in the matrix
What is LOG?
Baby, don't hurt me.
Don't hurt me.
No more!
So.....where are the luts you spoken about ?
why does standard look so blurry at 5:36 while log is much more clear and sharp? u said log is for colors shadows/highlights, not sharpening so now i dont understand it.. i feel like while u were editing log colors u also sharpened it...
I never add sharpening to video footage, and what would be the point of doing it here 🤷🏻♂️
@@HarvVideoAudioStuff so what is it then, is left one out of focus slightly? or v-log actually makes video sharper? i mean if it does then its actually worth unlocking. shadows/highlights wasnt really good enough reason for me but that sharper video is deal maker
I wish I could tell you but it was ages ago, I wouldn’t have changed the focal point between switching modes…not intentionally anyway 😂 from my experience there’s no real difference in detail/sharpness between rec709 and log so just pick based on your dynamic range requirements and colour preferences 👍🏻
@@HarvVideoAudioStuff okay. thank you man for video and responses, ur cool
6:10 Spot the 5 differences 🤔.
🎤Baby don’t hurt me...🎤
Log is Pores are the same?
Not the same, log is a gamma (contrast) curve and prores is a ‘wrapper’ for the file, similar to xavc etc. So you could have a prores video file which was filmed in LOG. Hopefully that makes sense, I tried 😅
@@HarvVideoAudioStuff thanks ,as that l am a very New in this area 🙏
good video with not very good thumbnail
700 liker
😎😎
so blackamgic BRAW = log?
It can be LOG if you want it to be, just depends how you want to grade it 👍🏻
What is LOG? Baby don’t hurt me, don’t hurt me, no more
“After all, the majority of films are shot ins som sort of log profile”. I differ, sir. They’re 99,9% shot in RAW
...and likely edited in a log format such as red log or arri log-c. Was this comment really necessary? 😂
i am desperately trying to understand log so forgive me if i come off as a bit of a devil's advocate; but in the first example, you said you exposed log to be somewhere in between, but you never did that standard profile, so the fact that you got somewhat better results with log there couldn't it simply be because you set the exposure to midway, and you could have achieved the exact same result with standard?
