[The haltman]

Hi,
I've an Ubuntu distro, I have an AVI file wih MP3 audio, I'd like to remove the audio and add a new one changing the frame rate of the video.
Can you pls explain me how to do it and what sw to use? Or simply give me a link to a good guide.

Thanks in advance

You can use mencoder to accomplish this task.
Make sure you have all files to be muxed in the same directory.


Step 1 -- Stream copy the video removing the audio

Example:
mencoder inputfile.avi -ovc copy -nosound -o outputfile.avi

Step 2 -- Stream copy video changing FPS and mux audiofile into video

Example
inputfile.avi -ovc copy -ofps 15 -oac -audiofile audio-to-mux.mp3 -o muxed.avi


Gentoo has a good guide on mencoder. Check here:

Hope this helps!
