According to the documentation on the TINTERLACE video filter, the filter mode called MERGEX2 will "Move odd frames into the upper field, even into the lower field, generating a double height frame at same frame rate." But it doesn't do this, at least in some cases (not sure about all cases). The first frame in a sequence should be considered frame one (an odd frame) for the purpose of this interlacing algorithm. However, that is not what's happening in my experience. At least with raw video (using "-f rawvideo") it's treating the first frame as frame zero (an even frame) and thus my first frame (which contains top-field data) ends up getting put into the bottom-field of the output video, and this is messing up the output. Please fix this. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel
