Dave Lozinski Re: Sony Vegas Pro 9.0 – – Rendering Problems (Low Memory)
by Dave Lozinski on Dec 24, 2010 at 4:33:25 am

With this “locking” issue I experienced the same thing. What I did to resolve the issue is I started taking media events out of my timeline one by one.

In the end, I found everything rendered perfectly when I removed an AVI file.

So what I did is I converted that AVI file to a wmv file and then everything worked perfectly.

That means it could have been either the codec which wasn’t working for some reason, or the AVI file itself was bad somehow.

Either way, that’s what I would suggest you guys try doing, especially if nothing has changed last week *that you are aware of* (as things are always changing on Windows systems).

Hope this helps.
