VEGAS - Using GPU Acceleration causing choppy frames in Video Preview

Benjamin-Davis wrote on 12/20/2022, 1:08 AM

I am on the verge or purchasing the newest version of VEGAS Pro, but I have a really frustrating issue.

I am trying to use my GeForce RTX 3090 graphics card for GPU acceleration of video processing, but when I preview my footage, most of the footage in the Video Preview window is choppy and there is an extremely frustrating series of jagged parts in many frames that I can't seem to get rid of while previewing my footage in the Video Preview window. I have gone through a lot of forums and YouTube videos trying to solve the issue, but nothing has worked.

I have three options for GPU acceleration in the Video Preview preferences window:

Off
Optimal - Intel(R) UHD Graphics 770
NVIDIA GeForce RTX 3090

The issue I described above happens if I choose either "Off" or "NVIDIA GeForce RTX 3090." However, when I select "Optimal - Intel(R) UHD Graphics 770" the issue does not happen and the video plays back smoothly.

Because my NVIDIA GeForce RTX 3090 is far more powerful than the Intel(R) UHD Graphics 770, I would like to utilize it for previewing my video and let Vegas utilize my hardware for more efficiency and performance.

I am really hoping someone knows how to fix this, because I am starting to lose my mind.

Attached is a video I recorded of my screen, so you can see exactly what I am seeing when I am viewing and playing back footage in the Video Preview window. Hopefully this gives you a better idea of what I mean when I say "choppy" and "jagged."

Two last notes: This issue has nothing to do with any kind of rolling shutter issue or CMOS sensor side effects. Also, I am using Windows 10.

Hi Everyone. I am having a similar issue with video preview. Previously I did not have this issue but after the latest update, it arrived. My preview screen freezes and only makes changes when I close the window and reopen it with Alt +4. Can someone help? It continues to freeze unceasingly

The scopes , graphs and other monitors work in real time, but the preview video doesn't. When I close the preview window I see the change in the frame, then I have to open another video preview again to see the next frame. This never happened before until the latest build.

It's certainly better to start a separate thread, since this one has already been marked as "solved" here, and you also have different system requirements.

those specs say nothing. See my computer specs in my signature. What specific make and model i7? What specific make and model Nvidia? How much RAM?

And yes, start a new topic post if you want help.

Hay. I am having same problem that preview video for 4 k files are really laggy and impossible to work with. First i thought its my hardware but working with adobe or capcut its working like a dream i can add 10 effects and still its running like a dream. I have i5 12500, 32 gb ram, ssd harddrive, gforce 1060 6gb. I tried everything but problem is not solved. It seems also that even when i change from graphics settings that vegas to use gforce 1060 it still uses intel770 graphics. Also what i noticed is that other editing softwares are using more ram but vegas is not. Anyways maybe somebody knows how to fix preview video massive lag issue. Its lagging even draft quater setting on 4k 100 frames videos but adobe premiere is running like a dream

@reiko-Reiko, you haven't stated which version of Vegas you are using or provide any information on what the 4K file is. What created it. What is its bitrate, etc.. Use MediaInfo to figure that out.

Also what settings in Vegas did you change? Specifics provide the information needed. Generalities don't.

Read this POST and answer "B" and "C".
