ffmpeg -i burosch1.mpg -map 0:v -c:v libx264 -vf fieldmatch=combmatch=full,yadif=mode=1:deint=interlaced -preset veryfast -crf 10 burosch1.mp4 The end result will be in 50p and without the patch randomly have the frames in the wrong order. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
