Sony Vegas 9 Audio Problem

[fdegrano]

Ok, I have about a 1 hour and 20 min home movie that I'm trying to encode. When I encode only a short region (ex 1 min) the output video plays perfectly with audio and all, but when I encode the entire hour and 20 min video, there is no audio. At first, I was thinking that I had some missing codecs or something, but that wouldn't make sense because the video played the audio when I encoded a short part. Also, I tried importing the output video back into vegas, and it shows that it has an audio track, but it is flatline the whole way through. Any solutions?

The first question is does the whole video itself play the audio in the first place. If it did you can try encoding the audio track by clicking on the audio in the timeline and a rick clicking on it, choose "Apply-Non-Real-Time-EventFX" from the popup menu, then choose "ExpressFX Audio Restoration" from the list and adjust it a bit.

all the audio and music works perfectly playing from the timeline, but after encoding, no audio

So try recoding the audio either like in my earlier suggestion, or seperating the audio stream from the video by using virualdub as an *.wav file and replace the existing stream in sony vegas with the new *.wav file.

i think the problem is with encoding for long periods of time and not with the audio tracks for the individual clips. like i said, when i render short loop regions, the audio is fine, but rendering all of it, there is NO audio. same settings and everything between the two.
