Garbled audio after rendering in Vegas.

Need help. Has anyone run into this problem? Editing my avchd footage 1080x1920 60i in Vegas pro 10e. audio plays fine on the timeline but
after rendering out to .ac3 pro its all garbled. Almost sounds like I'm playing it backwards and some times it has a reverb sound to it.

I tried re-rendering to a different formats MP3 and wave I had the same problem. I then tried rendering only 2 minutes of the 52 minute timeline and the audio was good. I then when back and rendered the 52 minutes and the audio was garbled again. I then closed Vegas and re-opened Vegas and re-rendered my 52 minutes this time the audio was good.

This problem has happened on other jobs so I know its not a isolated problem to this one job.

Has anyone experience this problem before? Are there any fixes or work around for this problem?

Thanks, Jerry K

I had this happen to me in v10 when my hard drive was extremely full

so i figured it was some kind of disk issue

I deleted a lot of stuff from the drive and that seemed to have worked

I may have also put some of the files onto another hard drive in order to split the work

My 1TB drive is only 40% full but thanks for the reply.

I get this result more than occasionaly, less than frequently -- probably about 20% of the time.

I sigh, I close Vegas Pro (10.0e), I re-open Vegas Pro, I re-render/re-encode, and it generally is good.

I haven't tried Vegas Pro 11, yet.

I wouldn't expect that my case is drive-space related. I render to various drives & haven't noticed any correlation to target drive available space.

Thanks Jerald. Now I know its not just my setup.

There is nothing inherent in the design of a hard drive that would cause it to garble data as it gets full. The only thing that changes as a drive gets full is that it slows down and that's just due to the physical properties of data location on a disc. The transfer rate of data on the outer tracks of an empty disc is faster than the inner tracks of an almost-full disc.

I also get consistently low audio levels with Veas and DVDA.

In what way are you getting "consistently low audio levels", there is also nothing inherent in the design of Vegas or DVDA that would cause this.

Posting a 60 sec sample of both the original audio and garbled audio may help others here help you to pin it down.

That being said, this is a relatively unusual situation.
