Thanks. My system is :

Vegas Pro Edit Version 18.0 (Build 527)
Windows 11 Home 24H2      
AMD Ryzen 7 7700 8-Core Processor  3.80 GHz
RAM 64.0 GB (63.1 GB usable)      
Graphics NVIDIA GeForce RTX 4070

Here is a screenshot from Vegas Preferences and a screenshot recording of the timeline:

The Documents folder with OFX Presets is under Users\Mus\OneDrive and all seem to be all present.

@Murray-Webster you can upload images and video direct to the forum. Many people do not like clicking on links to other sites especially to see pictures that can be embedded here. For source video examples it's necessary to use a third party upload location but for screen recordings they can be uploaded directly here too. Just click on this button to upload:

If you change the GPU Acceleration to "Off", does it still do that?

What version of the video driver do you have installed?

Have you considered trying it in VEGAS Pro 22 (which has many updates over 18)?

@Murray-Webster The mp4 recording you uploaded plays and edits fine on my laptop in Vegas 19 as well as 22. The video parameters are innocuous enough for any version of Vegas, if that's what you used in the Vegas 18 project itself. As suggested above, I'd also guess your video drivers might be at issue. If you used some other format of clip in your project, you might want to upload that instead. Ideally, in a zip with a veg file of a project that illustrates the behavior.

What version of the video driver do you have installed?

Thanks! Here it is with GPU Acc off:

FWIW The Control Panel has Hardware Acc on.

The latest driver is installed 32.0.15.6614 (6/11/2024)

I uninstalled Vegas Pro Suite 21 for the time being but it displayed the same behaviour. Works fine in 18 and 21 on both my laptops.

Heres' the original uploads which I seem to have accidentally deleted:

All of the clips are AVC captured by a Logitech C922 and work fine in 18 and 21 on both my laptops (created with GeForce GTX 1060).

An update:

I contacted the suppliers of the PC and apparently NVIDIA have Gaming and Studio drivers so we updated to Studio for Creators. It made no difference to Vegas Edit 18.

I installed Vegas Suite 21 (build 315) and ensured that all preferences are identical to the laptops where the program works. It has made no difference and here is the video:

Strange that it goes wrong at the same place but it doesn't always do that.

Where do I go from here and why doesn't it work on a brand new powerful PC system?

Thanks

Mus

Here is a video further demonstrating the problem, opened immediately after boot up.

When I click along the timeline to the end the Vegas preview snapshots show the correct screen splits, chroma key and panning.

However, after engaging Play, the clips start randomly flashing after 10-20 seconds and the effects disappear.

When I stop the video and click along the timeline the Preview stills are now also corrupted.

This is a copy of the original .veg on the new machine which then plays perfectly when ported back to the lower spec'd laptop.

Any thoughts - should I open a ticket with Magix or are they on the forum?

I'd open a ticket and share the project and files with them if you can.

@Howard-Vigorita how did you manage to download the file?

@Reyfox The link is to an html web page. When I click on it in my FireFox browser, there's a download link in the upper right corner of the web page that comes up. OP would get better feedback uploading the media clip itself the same way. Particularly if the media in his Vegas project is not a screen capture like what he uploaded.

An update:

Magix suggested turning off GPU acceleration and Dynamic RAM to 0, then resetting the software then re-installing to the Win 11 Administrator account, none of which have helped, unfortunately.

On Preview and Rendering (very quick on the new PC!) looks great for exactly 18 seconds then timeline clips flash on and off with no FX.

Waiting for further responses....anyone got any more ideas..?

Cheers

Upload a clip that does the flashing to cloud storage for others to try. I was thinking DRP 0 might have worked as your files are doing the Vegas black GPU cache flashing which will show tracks underneath.

When you say "All of the clips are AVC captured by a Logitech C922", do you mean you recorded with logitech software or did you record using OBS with the same settings you're using to screen record your problem timeline playback?

Thanks UltraVista. The clips are captured by Logitech Capture and any of them will flash after a consistent number of seconds within each project wherever I start on the timeline. e.g. 18 seconds in one project, 22 seconds in another etc. 11Mb example attached.

I've played around with DRM from 0 upwards and nothing makes a difference.

All works on my two laptops. Magix don't seem to be offering any more suggestions.

OK, after experimenting today I'm getting the feeling this is to do with the NewBlueFX Split Screen activations.

I have 3 machines and the Web Log in shows up to two activations (I thought you were only allowed 1?).

I deactivated them all and activated one machine but still goes wrong.

When I reactivated the computer where it was working it is now displaying the same symptoms so I can't progress any of the projects I am working on.

I think the NewBlueFX Overlay 3 came with Vegas 18 - is there a problem with new activations?

If I paid $99 to upgrade to Version 5 will it fix it?

Cheers

@Murray-Webster Generally speaking, NewBlue products allow two activations (that way if you have a desktop and laptop you and use them on both, for example.)

If you are getting some display issues, purchasing another license certainly won't fix that. If you open the settings for the NewBlue product and click on the "About" button, you can try turning off GPU Accleration to see if that helps.

OK thanks.

Wish I hadn't de-activated NewBlue in the old laptop that was working. Adding NewBlue to clips in DaVinci Resolve causes similar issues.

I've submitted a ticket to NewBlue and updated Magix.

I think I tried GPU off but will test again.
