Comment (by RedError):

 Replying to [comment:4 cehoyos]:
 > I don't think this can be changed.
 The change would be to ignore transparent colors when creating the
 palette.
 I wrote something similar in PIL, I don't see why this would not be able
 to be changed in ffmpeg.

 Or is there something I'm missing? Not daring to reopen myself.
