I notice that if sometimes I play music or watch videos while Vegas is rendering, that audio will disappear on the completed video.

How many times have you tried rendering? Does the audio play in your Preview within the project?

It's best to close out unnecessary programs, re-render and just walk away from the PC.

Thanks for the reply. I've tried rendering six times now and each time i have left the computer alone with no other programmes running. I've even tried reducing the movie in size but i still lose the audio 3/4 way through. I even tried rendering straight to disc without going through DVD Architect. I haven't tried the preview yet so i'll check that out.
I've tried the preview and the audio is there. I just lose it in rendering. But why do i get 3/4 of audio and not the last 1/4?

I think Crawdaddy has a good idea..Do you by any chance use volume envelopes and perhaps it is muted at that point? Check via the preview and the master bus (audio) to see if you are losing the audio for a reason.

I've experienced the same (or similar) issue recently. I'm taking an MPEG-2 file that was recently rendered from MTS and simply slicing out a small section of it as another MPEG-2 file. (Large file contains a full inning of baseball game...I'm finding highlights and creating individual highlight clips).

Sometimes there seems to be no audio...sometimes it's very low volume muffled audio. I've had to shut VMS down and restart it ...then repeat the rendering and it does fine. Doesn't happen every time, but last night happened about 5 out of 15 times and 3 times in a row.

I was not doing anything else on my computer. I even disabled the firewall and anti-virus program (GData).

Very annoying.

Well this time i have reduced the project to the last frame before the audio spluttered then disappeared the last time i rendered. Yet again the last 1/4 of the audio is not there. I am really disappointed with this software.

I'm getting this exact same problem as well;

I've dragged all my Kodak Play Sport videos from my recent holiday into the timeline (about 2 hours worth); I can play them from start to finish in the timeline without issue.

As soon as I render the project and play back the final render (Blu-Ray ISO or mp4 file) the audio starts to stutter 3/4 of the way through and then just cuts out completly.

I can confirm no changes have been made to the audio timeline and that nothing is muted.

I've tried encoding 3 times overnight and got the problem every time.

Source Videos are:

Video: H264 - MPEG-5 AVC 1920x1080 29.970029 Progressive (.MOV)
Audio: MPEG AAC Audio Stereo 48000Hz

Project Settings are:

HD 1080-60i (There is no 29/30 progressive option)
Master bus mode: Stereo, 48,000hz, 16 bit depth, resample - best.
Ruler: SMPTE Non-Drop (29.97fps, Video)
