Those are not macroblock errors. They are typical optical flow errors. Motion interpolation is never perfect , there are always some types artifacts, occlusions, edge morphing There are several other methods and algorithms you can use outside of FFmpeg, some are GPU accelerated. e.g. svpflow, mvtools2, DAIN, twixtor, resolve. For artifacts around frame edges, letterbox edges usually some form of padding is used. I don't think ffmpeg minterpolate has those. -- Sent from: http://ffmpeg-users.933282.n4.nabble.com/ _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
