Vegas 11 pixelated errors in normal fades?!?!

Hi everyone,

Ever since I installed Vegas 11 I have been seeing very annoying random HUGE pixelated transitions at places in projects that were okay before in Vegas.

It seems to happen at random, and only shows up after I render the projects, normal simple fade transitions have huge pixels in them , its so bad I can't use the output and have to render again.

Sometime I even see them inside the timeline, it looks like I used broken pieces of footage where the tape was damaged or something, but the footage is 100% HD perfect material...

Does anybody know what this is and how to fix it?

I already tried turning off the GPU acceleration but that was not the problem.

This issue is often assocated with specifying too low a bitrate when rendering. What encoder & render template (& bitrate) are you using?

No thats absolutely not the case, I render in Full HD with a preset 1080 HD WMV.
I always use the same preset and also have rendered these same projects that I get errors with now many times before in Vegas 10 without any problems.

So what happens is I load an older project with just some simple crossfades in it, render it and at random points I get HUGE pixels/distortion in my final movie, like I said, as if a tape had a major dropout or something.

This is absolutely not normal, and not an error in the settings or something, but looks like a serious bug....

Could you possibly post a screen grab of the pixelation? Might help us see what the issue is. Maybe render out, then import back into Vegas then find a point to grab during a crossfade.

Can you render the same fade in V10 and V11 just as a test to make sure there is a difference between the two versions in this regard? I know you're positive, but all you need do is grab the one clip and throw it into V10.

As Jerry stated I have also noticed that temporal compression (especially wmv) has a difficult time with a smooth transition to black.
Also try two-pass if you haven't already. The encoder needs to "know" that a really tough scene is coming up that is nearly impossible for it to predict.

Sorry for my late response, I'm working on a new project now and this does not seem to have this problem fortunately, it seems to be in projects that are already made in Vegas 10. If I come across it again I'll post the footage, somehow I can't find a piece that has the problem since I corrected it by making scenes a little shorter etc. The first time I actually thought it was a tape dropout or something, because it went away as soon as I took off half a second of the start of the overlapping footage , but it was not because I've seen it a couple of times after that, also with projects that I already rendered out perfectly before, really weird...I have a gutfeeling that it has something to do with my graphic card.

If it happens again, try turning off GPU acceleration for timeline playback. I had this problem with fade transitions in previous builds and turning off the GPU fixed it. The latest Vegas Pro 11.0 build 595 has also seemed to fix it so I now have GPU turned back on but maybe not in the case of VP10 projects in VP11?
