A very simple addon for making videos from a fbo.
Make a video from a sequence
ffmpeg -framerate 60 -i frame_%d.png -crf 10 -vf 'setpts=1.0*PTS' -pix_fmt yuv420p -c:a copy -tune grain export.mov
Make a nice fade out on audio
ffmpeg -i test02.mp3 -af "afade=t=out:st=65:d=5" test03.mp3
ffmpeg -framerate 60 -i 0000%3d.png -crf 10 -vf 'setpts=1.0*PTS' -pix_fmt yuv420p -c:a copy -tune grain export.mov
make a gif to a mp4
ffmpeg -i file.gif -pix_fmt yuv420p out.mp4
