I try to convert a mpeg2 video to mov with codec ac3 but when put ffmpeg -i 1.mpg 1.mov the audio don't convert.

¿Anyone know why?

  • So your source is MPEG-2 video and AC3 audio and you wish to convert to H264 video and AC3 audio in MOV?

  • Exactly, and then only convert the video, without audio...

  • You have exceeded the maximum file size of 512 kilobytes per paste. PRO users don't have this limit! :( Damn!

  • How big is the .MPG? Run the following command and paste its console output: ffmpeg -i 1.mpg -c:v libx264 -c:a ac3 -b:a 192k -t 5 1.mov

1 Answer 1



ffmpeg -i 1.mpg -c:v libx264 -c:a ac3 -b:a 192k 1.mov

in order to convert to a MOV file containing H.264 video and AC3 audio. I've used 192kb/s as bitrate for the audio and the H.264 encoding will use the defaults of CRF 23 and preset 'medium'.

To convert only video, and strip out audio, use

ffmpeg -i 1.mpg -c:v libx264 -an 1.mov
  • thanks for the answer, but still not convert the audio, the specs of source video are: Vídeo: MPEG-1/2 Video (mpgv) 720x576 25fps Planar 4:2:0 YUV and Audio are: DVD LPCM Audio (lpcm) Stereo, 48000 Hz 16 bits.

  • The conversion is successful, but the video does not have audio. Don't show any error...

  • Try converting to AAC and see if it works: ffmpeg -i 1.mpg -c:v libx264 -c:a aac -strict -2 -b:a 192k 1.mov
