Problems with Vegas Pro 17, sluggish and render is very glitchy

Kevin-Osborne wrote on 7/31/2020, 5:37 AM

Hi,

I’ve been trying to do a short basic video today in Vegas Pro 17 build 452 on Windows 10 but it’s running very slowly and the rendered video is full of glitches. Up until today I've had no issues. My project properties are HD 1080-60i (1920x1080, 29.970 fps) and ’m rendering with Sony AVC/MVC Internet 1920x1080-30p, although I’ve also tried a few others but all appear the same.

There are 6 channels:

3 text

1 picture

1 solid colour

1 audio Mp3

Out of frustration I’ve ended up using Vegas Movie Studio 16.0 Platinum on the same system which worked fine. As a test I opened the Vegas Movie Studio 16.0 Platinum project in Vegas Pro 17 and rendered it but this is as glitchy as the project I originally created in it.

I’ve uploaded the 2 to Youtube:

 

Vegas Movie Studio 16.0 Platinum

 

Vegas Pro 17

 

Please advise.

Thanks,

Kevin.

"My project properties are HD 1080-60i"

Why do you have an interlaced project setting when your source and your destination is progressive?

The kind of nonsense looks like video adapter. Tell us about yours.

Which ones?
What are your settings at Options/Preferences/Video ?
If using a GPU, which one and which driverversion exactly?

I get that glitching all the time if I have "GPU acceleration of video processing" turned ON while rendering (Options->Preferences->Video). As long as that's turned off, the glitches disappear.

It's frustrating as I'd like to have that switched on while editing but having to keep toggling it just for rendering (which requires restarting Vegas) is a pain so I just leave it off.

Note: this is not the same setting as rendering with GPU (in the render dialogue) which I can use quite happily.

Hope that helps

David

Thanks John, I'll read up on that stuff.

Thanks David that was it! Must've ticked it by accident at some point. Thanks again!

Did you miss John Dennis's question?
I would go into this further.
Switching off the GPU is not a solution, but just a workaround to test where the rabbit is in the pepper.

I agree with that in principle, of course, but a while back I spent a whole afternoon faffing around with various tests (with the GPU on) and could find no solid evidence of what was triggering the flickering.

All my projects were progressive so the query about why using interlaced material in a progressive project (while a valid query) is not, I think, related to the bug at issue.

Cheers

I normally do much more intensive projects with multiple FX, automation etc. and have never had this before, so personally I'm happy that it's now working & I can get on with editing my latest video. I'll worry about investigating further if I have more issues.

Thanks all for the advice and help.

Kevin.
