2problems: editing audio from mpg/extract audio from divx

[jengerz]

i want to touch up the audio in a mpg file by eliminating some static in the background. which program(s) is good for the job? And how do i put the new audio back into the video?


another different problem is when i tried to extract the audio from an avi(divx) file using virtualdub-wanting to convert to mpg then to vcd, i couldn't do it. i followed the guide on this website, but i seem to get an error: "The requested audio compression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested format."

anyone know what to do?

For your MPEG Question:

Use TMPGEnc to demultiplex the audio (you might have to convert the audio to wav before you can actually clean it up) Do whatever you wanna do, and then convert it to an mp2 using TMPGEnc and then re-multiplex with the new audio file. Make sure that your formats are correct when you re-multiplex...

For your divx question:

Check to make sure that the source audio is going to be compatible with the output audio that you want. You can start by going to audio/conversion in vdub and where it says "No change to (blah blah blah)" if the source is mono and you want the output to be stereo then you'll need to use direct stream copy on the audio menu, save as wav, and then use an audio editing program to convert the audio from mono to stereo. (that was a "for instance") (vdub can convert the sampling rate and the bitrate for you but it is safer to use an audio editing software) just take a look at those settings and you'll be able to find the problem.

P.S. You don't always have to demultiplex the audio to make it work...

Which program for cleaning the audio is reliable?

CoolEdit or GoldWave seem to be the audio converters of choice...
