Hi, I am looking presets rendering for YouTube.
.webm VP9 YouTube Cinelerra, currently it looks bad on youtube.
Many recommend uploading it in the best possible quality.
searching i found this: https://support.google.com/youtube/answer/1722171?hl=en
is it possible to put this in Cinelerra?

I'm not sure how to do it in Cinelerra.
Unfortunately, I haven't made any progress since that thread that was mentioned. In fact, I'm even more confused. I've also tried contacting Adam Williams, but he's been known to never respond.

If anyone uses a workflow for color in CinGG, their input is welcome....
When I have time I will continue to investigate the color.
For youtube now I use yuv444p for 60FPS.

Making a profile is very confusing.
This is currently working for me.
Edit:
As far as I understand.
FFMPEG will settings default your video If you don't use parameters.
But in Cinelerra it will use the FFMPEG Defaults (presets) not your video.
< Mediainfo > it helped me understand this better.
I think you are now the expert! Thanks for sharing your final setup. Will it be OK to use this in the manual as a suggestion?
But in Cinelerra it will use the FFMPEG Defaults (presets) not your video.
This sounds true as far as rendering goes.
Adding it would be fine.
FFMPEG has many settings.
it would help people used by other video editors.
Shotcut and Kdenlive rendering work almost the same.
but in Cin GG rendering changes many things.
Well after a few hours.
I already have the colors of the compositor.
If the project is in:
YUVA-8bit color model> rendered in yuv444p
the final video will be equal to compositor.
------------------------------------------------------------------
To get colors equal to the original video. (not compositor)
RBGA-8bit color model> rendering yuv420p or yuv444p
All my tests are for OBS studio.
No hardware acceleration. (Vaapi or Nvenc)
Usage to record OBS:
Color Format: I444 (yuv444p)
Color Space: 709
Color range: Full (JPEG)
This is working for me in OBS. 😀
Never use.
Model color: YUVA-8bit
Rendering: default Pixels format yuv420p
The color will be horrible very gray.
Thank you for your testing and tips. They are very interesting and help provide clarity.
If you find out more information please don't hesitate to let us know. Eventually we may improve the manual with a section on color space management.

After testing different videos at 30 - 60 FPS
g=30 there's no need.
x264-params cabac=1:me_range=24:bframes=2:keyint=60:keyint_min=25:qpmin=0:qpmax=69:qpstep=4
it already does.
