Thank you! This sample appears to confirm that GraphicsMagick is right and FFmpeg is buggy. To avoid creating more incorrect (ffv1) encodes, I (strongly) suggest to first fix this issue and commit your patch to support more bit-depths but if you disagree, please feel free to commit! There is also this sample though: http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket2392/ The only solution I can think of is to change the semantics of the fourth dpx layer by default and to add an option (to the decoder) that allows using the current semantics that defaults to "auto" reading the encoder value.
