Summary of the bug:
When FFMPEG writes to RGBA PNG 32bit .MOV Quicktime, it seems to label
alpha to be interpreted as 'straight' when we need the files to have 'no
label' so After effects can remember it's own interpretation setting for
'Import of an unlabeled alpha'. Otherwise users will constantly have to
force the interpretation of every FFMPEG created PNG file they import
regardless of what After Effects is set to.
Version of FFMPEG: ffmpeg-20170921-183fd30-win64-static
How to reproduce:
ffmpeg.exe -r 24 -f image2 "explosion.%%04d.exr" -vcodec png -pix_fmt rgba
-y "explosion.mov"
If we are doing something wrong, we apologize. We have searched far and
wide for an answer.
