cut parts of xvid mp4 without rerendering

[robroth]

I have a file with the following properties per Vegas Pro 9

video:
704x304x12 @ 23.976fps
alpha none
field order none (progressive scan)
xvid mpeg-4 codec

audio:
127 kBit/sec 48,000 hz stereo
Lame MP3

I went and chopped a couple of short sections out (so they were replaced with just black video and silence and wanted to save this back without having to transcode the whole thing again. As I have not been able to figure this out, I tried manually setting the output to all the same settings as above, bowever Lame MP3 doesnt have 127 kBit and even selecting 128 and confirming takes me back to the summary and shows no audio will be output. I go back into the audio tab and everything is blank. I'm assuming that's perhaps because I don't have that particular codec on this machine?

In any event, is there a way I can just remove those sections without having to re-transcode?

Please don't point me to virtualdub or virtualdubmod unless you have a walkthru for exactly what I'm trying to do, I have tried again and again over the years to use those programs and I just don't get it I guess. I'm an extremely technical guy, yet somehow I always fail miserably using those applications. Thanks much.

Virtualdub or virtualdubmod, set video and audio to direct stream copy and then set start and stop and delete and save, see http://www.dvd-guides.com/guides.php?category=avi&name=avichop

avidemux, same method set start and stop and delete, see https://forum.videohelp.com/topic357763.html scroll down to cutting.

Thanks much, so I used avidemux and it was a breeze, this looks like a pretty cool tool, thanks for turning me on to it.
