Unwanted Audio

Last November I asked about cutting excess audio from an mpg I was given without having to rerender for DVDA.

The answer was to render as separate streams and simply put an end marker in the audio to match the end of the video

This worked fine.

Now I want to archive the original files but thye video section takes up about 250MB with the audio (which is just noise) taking up a further 500MB.

I would still prefer to not have to re-render as I have several like this. Is there another option to simply cut the audio from the end?

Cheers

TMPEG will demux the video and audio streams and allow you to save them as separate files, withour rerendering. After demuxing, you can just delete the audio file of course.

Thanks Richard but I am not sure that will help me.

I need to cut the audio from the end of the video only. So if I demux, cut the audio at the same place as the video would finish I will then have to combine the two again which, surely, would mean a re-render in Vegas 5?

Have I missed something more obvious or trying to crack a nut with a sledgehammer?

Sorry, I didn't quite catch the exact problem, thought you were trying to lose all of the audio.

OK, if you trim the audio as you describe, and then use TMPEG to multiplex it back with the video stream, there will be no re-rendering done (on the video at least).

The "modern" way to do this, using an HDV-type workflow, would be to convert the MPEG to an intermediate codec, trim the audio in Vegas, and then rerender as MPEG. There will be some loss this way, but hopefully it should be unnoticeable.
