Problems vegas 20 frame flicker

andyrpsmith wrote on 7/5/2023, 7:34 AM

Looked through frame by frame and cannot see what the problem is, no flickers or green frames.

Green frames usually mean a problem with your graphics card or graphics management (drivers ect).

Hello friend, thanks for your answer!
The first frame blink is in the second 5, if you go frame by frame you can see how suddenly the first frame of another part of the video sneaks in, it is only one frame for this reason the blink is fast, the next blink is in the second 10 and in the second 19 you can see the most obvious flickering which is when a frame with the number 2023 skips.
This happens both in the preview of the video when I edit it and in the final result after rendering.

On the video I'm seeing your problems.
No idea what the reason can be without information about your used hardware, Vegas Pro settings and driverversion for possible GPU.
So give the needed Information following this tutorial under B and C : https://www.vegascreativesoftware.info/us/forum/important-information-required-to-help-you--110457/
and put the important things in your signature like mine.

B5-

In video preview when you are editing videos and in its final rendering vegas 20 is giving me problems and it is impossible to get a video with correct display, during the video there are green flickers and also 1 frame of any part of the video creates flickers, no I understand what's happening, I bought the license for this Vegas 2 months ago and I still haven't been able to work with it, I'm still using Vegas 18 and Vegas 14 to edit my videos, I'm attaching a little video so you can see the failure, please yes someone has a solution for that helps me a lot, the situation is very distressing for me.

I want to emphasize that on this same PC I use vegas 14 and vegas 18, editing the same videos and project data and re-rendering and everything works correctly, only this new vegas 20 gives me these frame flickering problems, and they are not color corrupt frames green or black, they are grams of the same video that vada x time jumps throughout the filming, this happens both in the preview sony vegas videos and also after re-rendering in the final product.

@angel-c Hi, the Bitrate 12,000 is quite low but that would prob just give you a poor quality video,

Can you share a pic of the timeline, it looks like the start of a repeat loop play, if you dragged the event to make it longer that would create a little ▼ at the top indicating it started loop playing again

Like this where i've put a green arrow

RogerS wrote on 7/6/2023, 6:16 AM

Seems like a problem with dynamic ram preview. Usually turning GPU acceleration off in preferences/video fixes that. In your case you still see the problem? What if you turn it back on but set dynamic ram preview to 0%, does it work better?

Also there's no point in setting a variable bitrate with maximum and average the same. Maximum should be greater for scenes that are more complex.

Is your NVIDIA driver from 2018? Try the latest one that's available for your GPU.

Thanks for your answer friend, here are the photos you requested.

Thanks for your answer friend, now I'm going to try what you tell me.
I tell you that I bought this pc from England and it arrived 2 months ago, it's an old HPz600 workstation modified a bit, my brother has the same one and it works very well with video rendering, but my brother changed the graphics (he didn't use vegas20)
I think that the error I'm having with Vegas may be due to this graphic, I don't mind buying another graphic for everything to work, I just need the opinion of experts like you to know what I have to do, if this is a configuration error or It is the graph that is causing the failure.

Former user wrote on 7/6/2023, 6:26 AM

@angel-c That is just the video that you shared dragged out to reveal that ▼ ? I did it like that just to show you how the ▼ would look,

Did you create this intro? I wanted to see the project that created it.

I see this

RogerS wrote on 7/6/2023, 6:33 AM

It's an issue related to the GPU. Try to get the latest driver you can from nvidia.com that works with this GPU. See if that helps.

Beyond that, turning off dynamic ram preview is a workaround (though will cause the render to happen more slowly).

If my searching is correct this is a GPU from 2010 that only has 1GB of VRAM. That is too old to work in VEGAS. You need a newer card to get benefits from GPU decoding, encoding and timeline acceleration. A RTX 20XX or newer GPU (or AMD equivalent) should work well in VEGAS.

Aha okay yes, I believe it but this is not a problem with this intro, the same error happens with any video, give me a moment and I'll prepare another video for you to see.

I see the vieo that you have given me and I have done the same, the error is repeated when I stretch the video in a loop.

Ok friend thanks for the information, I will try to continue reading the friends who are helping me and if nothing works buy a good compatible graphic.
The strange thing is that this same pc works very well with the other versions of vegas that I have installed, is it possible that vegas20 needs other resources and that's why it only has this error in vegas 20?

I'm going to try the controller that you tell me too.

@angel-c Thanks for the info.
Try also to use and render with Options/Pref/Video and Options/Pref/File I/O resettet to the defalult values

Please see the recommended system specifications for Vegas Pro 20:

https://www.vegascreativesoftware.com/us/specifications/#productMenu

As any computer intensive product develops over the years, so do the computer specifications needed to drive new features.

RogerS wrote on 7/6/2023, 6:58 AM

I agree with j-v to reset all settings first and see.

You seem to have the latest driver available for this GPU: https://www.nvidia.com/Download/driverResults.aspx/130177/en-us/ It's from 2018.

VP 14 uses the GPU differently than VP 18+ so I'm not surprised it would be fine with a GPU from 2010. I am a little surprised VP 18 and 20 are different as the system requirements are the same from my understanding. I think it was VP 19 that fixed issues with GPUs and dynamic ram preview but maybe that broke compatibility with older GPUs.

Any modern GPU should work much better in VEGAS Pro.

angel-c wrote on 7/6/2023, 7:31 AM

Same videos edited on the same pc z600 a vegas18 edition that looks perfect in preview and the final result and a failed edition in vegas20 that looks the same in preview as the final result.

I already tried this friend and it didn't work, I appreciate your help but this was the first thing I tried, I think the other friends on the forum are very well on the way to the focus of the problem, now I have to go to work but this afternoon I'm going to try the controller and if it still fails, buy a graphics card.

Angel-c, you can see what Vegas V20 finds when it detects your GPU options for both CPU and GPU by looking at this file. Just open C:\Users\Username\AppData\Local\VEGAS Pro\20.0\ gpu_video_x64.log with note pad to see what's inside. It will identify any errors it finds. Have a look and let us know what if finds.

@angel-c

The Shade Tree Analyst responds with his analysis.

In a Vegas Pro 20-411 project, I used the composite difference between Vegas18.mp4 and Vegas20.mp4 to find the sources of the flicker that you experienced on the timeline and the rendered output. By placing markers on each difference frame, I was able to seek directly to the sources of the errors. By knowing exactly where to look, I was able to quickly verify the malfeasance in a different application.

The Shade Tree Analyst responds with his Conclusion and Recommendations.

It's All GPU, All The Time.
Buy a new GPU once a decade or so.
Turn off all uses of GPU in Vegas Pro 20.

Thank you friend for your contribution to solve my problem, I am going to try everything you are telling me, but every time I am clearer that I am going to buy a good graphics card to get out of these problems.

Guys, I am very grateful for all your dedication of time to help me, I am going to try everything you tell me here, but to speed up time, can you tell me which graph you recommend with the characteristics that you already know about my PC and operating system and for the correct use of Vegas20 ? I don't care about the cost of the graphics card, I just want this pc that I bought exclusively to render videos to be the best for me, if you think that I have to change something else besides the GPU, please tell me because I want this pc to be a perfect video renderer, I render about 10 videos a day between 8 and 10 minutes and I want speed and of course an optimal rendering to be able to achieve more work.
Once again thank you all, you are an exquisite community and very kind people.
