Deleting audio from a video

Kurisu Makise · 23 Feb 2012 at 20:28

is the any software that will let me cut the audio out from a video and then replace it with lossless audio or if not supported better quality?

any help appreciated

What formats?

virtualdub could do this easily but it does not support a huge array of formats.

You could also use Windows Live Movie Maker.

You cannot edit audio streams directly but you can add a 'music' track and then change the mix slider on the project tab to full music so that it plays your selected track and none of the original video audio.

LAME at 640kbps for the audio

edit: doesnt look like it supports mp4 files

Windows Live MM will only go up to 440kbps on audio and 1920x1200 resolution when encoding.

Try ffmpeg - I just tried this on a test file and it worked (to humerus results dubbing another band over a bands video

). No need to re-encode so it takes seconds.

It didn't like me subbing a flac in over an original MP3 stream though, so you might need to stick to a high quality MP3 (or just work out the command line options which will let you do it, because it will do it I'm sure).

Code:

ffmpeg -i "video.mp4" -i newaudio.mp3 -map 0:0 -map 1:0 -vcodec copy -acodec copy video-new.mpg
