Rendered Audio files flatline

kirkdickinson wrote on 6/24/2003, 6:31 PM
I combined some audio files and took out blanks to shorten the time up and then rendered to mp3. (58 minute timeline) The mp3 wouldn't play in WinAmp and when I brought it back into Vegas, there are no peaks and there is no sound there.

I tried rendering to wav and I get the same thing.

The original files are wav files that I created in Vegas from Real Audio stream.

Any idea why my renders are blank?

Thanks,

Kirk

A few questions.
1. Does your project play from the timeline ok? I assume it does or you wouldn't have tried to render it.
2. Is your rendered file 58 mins of blank? If it's a short file you might just be rendering the loop region (uncheck this box at render).
3. Do you have any of the mute or solo buttons pressed on your tracks? I use these a lot when working on the project and sometimes forget to return them to normal before rendering. Vegas renders exactly as you have it set up to play in the timeline. Ie: if you have a track muted, it won't be rendered.

And some advice.
In your tinkering, try selecting a small part of the project (30secs or so) and render that with the 'render loop only' box checked. This will allow you to test the output without having to wait for the whole render.

Good luck,
Jon

Jon,

It plays from the timeline fine. No, I am not rendering a loop, already checked that. No mute or solo buttons pressed.

The project is basicly two wav files that I captured from a RealAudio stream. My internet connection is sooo slow, that RealAudio will stop for 20 seconds frequently to fill up the buffer again. I had to go into Vegas and take out the blank spaces. Otherwise I wouldn't normally bring it into Vegas to edit.

The rendered file is 58 minutes of completely blank audio if I render either as an MP3 or wav (M$ Wav) I tried rendering it to an MPEG 2 and it was silent, however if I render as an AVI, it has all the audio there.

Weird!

I agree, wierd!
I haven't come across this myself, but if I were you I would try an avi render with the max sound quality I could manage, and then try rendering from avi to mp3. For some reason vegas is having a problem going from your realaudio stream straight to .wav or mp3. Please post here if you find the solution!

Apparently, the problem only is showing up with my computer at work.

I just did an experiment and did a short version of the same thing with my home computer and it worked fine. It acted just like I expected it to act all along.

Same versions of Vegas, different computers. I have no idea why??

Vegas seems to be able to capture the RealAudio stream into a wav that works fine in the timeline, but won't render back out to wav on my work computer. Gets weirder and weirder.

The only audio flatlining problem in Vegas that I recall was a bug in the "Normalize" switch. It may or may not still exist.

Is your mp3 codec registered on both computers?

It is registered on the computer that is failing, but not on the one that it is working correctly on. I don't think the registration thing is the problem.

I will play with it some more this afternoon.

It appears that a crash and reboot of Windows cleared up my problem.

I allocated too much memory to Photoshop, then was playing in Vegas while having too many photos open in Photoshop. Whole system was dragging bad and crashed with a Memory error of some kind.

Now the files render just fine. Go figure.
