I updated AE today and in the export settings, h.264 option is lost. It was the most suitable codec for me to have films to upload on Instagram, FB and etc.
When I try the H.264 codec on Media Encoder, the colors are different, more pastel. Also, I tried QT - Animation codec and still, reds lose their saturation. How should I have small sized but fast exports?
it means the file colors are fine, and the problem is in whatever platform you are watching it in (if the files are not changed, then it's your browser) and unless you can change the platform, there's nothing to be done from this point because the file is fine.
