Incorporating Carl's suggestion as well of -vf setpts, the filter chain should look something like:
ffmpeg -i <inputfile> -vf setpts=PTS*0.8 -af=atune=25/24 <codec options> <output file> or if -r works for you: ffmpeg -r 25 -i <inputfile> -af=atune=25/24 <codec options> <output file> Just a heads-up: on a test clip, looks like using -ss and -r before -i causes frame-sync issues, so if you were wanting to skip forward into your test clip, make sure to use -ss after -i <inputfile>. > ~Steve > > _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
