Seems stream 0 codec frame rate differs from container frame rate:
47.95 (48000/1001) -> 23.98 (24000/1001)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '01 The Skank Reflex Analysis (HD).m4v':

    Stream #0.4(eng): Subtitle: tx3g / 0x67337874, PAR 1:9 DAR 16:9
At least one output file must be specified



I would like to get this video in English with an acceptable video quality.


Can someone tell me how to do it with ffmpeg please?

Best Regards
MArcos
