Ehm ok, in that case there seems to be something a litle strange going on there. When I do a: ffmpeg -i johanneswilm.mts -acodec copy -vcodec libx264 -deinterlace johanneswilm.mov It gives me a 34 second clip at 29.97fps. However, the sound and the original clip are only 17 seconds long. Only a: ffmpeg -i %(inputname)s -f yuv4mpegpipe - | yuvfps -r 60:1 -c | ffmpeg -f yuv4mpegpipe -i - -i %(inputname)s -map 0:0 -map 1:1 %(outputname)s gives me a clip with the right length. > > > > in an mts container (mpegts).
