Demux / mux .mov

[Evoks]

Hello, it's my first post on this forum !

Here is my problem, I've got a lot of videos with background noise in .mov format.
I have done a ruby script to automatise all steps.
But i'm blocked on this step :
I want to demux files, treat sound with an audio processing program, and remux audio with video.
All that stuff on Mac OS and scriptable (so in command line (ffmpeg, HandBrakeCLI...)) :P
I don't find a good solution, so if anybody can help me, it would be nice !

Thank you !

Moving you to our mac section.

Demux and remux with ffmpeg. Google how to use it.

But I don't any command line to fix noise.

[terryj]

Fixing noise would have to be done in an Audio editor such as
Bias, Audacity, or Amadeus II. Then a new AIFF file generated
from the clean file. Then that File muxed back in with the video.

Thanks for answers !

I already did it with Amadeus Pro, but it's not in CLI.. And that's the prob.
I tested to do that in Apple Script with a soft called UI Browser which can normally translate actions of any programs in Apple Script, but the script doesn't work well. And, moreover, i don't know if we can pass parameter to an Apple Script...

I'm a blocked..

It works now ! I used UI Browser in the good way !
So now, I scripted all the workflow to demux and correct the background sound in Applescript.
Now I have to remux corrected audio and video, certainly in ffmpeg.

If you are intrested to see the script, tell me and i post it !

Do you know the command line in ffmpeg to remplace the soundtrack from a .mov by another one which come from another file.mov

Since the answer of "Google how to use it" leads to this forum, here is the command line to demux:
The command lines for demuxing are:
-> to get the audio
ffmpeg -i input -vn -acodec copy output
-> to get the video
ffmpeg -i input -an -vcodec copy output
The extension for "output" is important: if you want you video embedded with an avi header, put ".avi"; if you want your aac audio readable on an iPod, put ".m4a"...

Note that Google only gives answers if some put them sometimes so if you know them, put them.
