Hi Laura and Ludo, > the colours are changed. Ie: the dark gray turns > green, and the white turns somewhat pink.
Commit 4bd2e78b893fef5ce1f12bec895ee8234cabaf1f fixes the colors. ffmpeg needed a different pixel format to set the chroma subsampling correctly [1]. I have been able to play the newly built cli and nocli videos in Firefox. Also, the combined video now starts in Firefox but stops just before the first transition. I think the concatenation step in the Makefile could be the cause. Best regards, Paul. 1. https://trac.ffmpeg.org/wiki/Encode/VP9
