Constants shutdowns & render failures since the beginning

Hello.

I have not posted for some time in this forum, despite being a Vegas Pro user and a Movie Studio user before that. I have been using Vegas Pro since version 17 and am currently using version 22.

I have suffered shutdowns in every version up to now! I have had to set the autosave function, but even then recovering the file using this option does not always return me to where I was before. I edit directly on the time line, producing videos for YouTube in the Flight Simulation genre. I have watched many videos on how I might mitigate these shutdowns, but mostly they do not work for me. The best option I have now is to disable GPU Acceleration in the OPTIONS/PREFERENCES/VIDEO section. Mostly, this allows me a long time before I get a shutdown. The downside of this option is that rendering often stops mid-render, so I turn the option back to ON to render and mostly it works. But I still suffer shutdowns and the occasional failure to complete a render.

My system is powerful - AMD Ryzen 9 9850X3D CPU, NVidia Geforce RTX 5070Ti 16GB video card, 64GB RAM and a 4TB Samsung Evo SSD. Could the problem be the preview screen? I keep it at GOOD/AUTO so I get to see something of what the output would be like upon rendering. During rendering, I often notice the preview screen struggling to show a transition for example and often I have to remove a transition and do something else to get the render to get past this point where it failed.

***************************

Now I am getting adverts to upgrade to Vegas Pro 23. I am very reluctant to do this, while I suffer these shutdowns. But if upgrading fixes this, then I am prepared to do it.

I'm sorry if this has been posted elsewhere. Like I said, I have not visited this forum for some time and I have reached a point where the frustration is really getting to me, so I would really appreciate some help and useful comments on this matter. I really like Vegas Pro - you do not charge a stupid monthly subscription and the software is easy to use, compared to some of the more expensive and often complicated options out there. I hope someone can help.

Thanks for listening,

regards,

Never pay more than £149 for an upgrade, Vegas offers discounts regularly. I have got upgrades consistently for £99/$99 just wait and keep an eye open.

Ok,

I got the upgrade price at £149 instead of £219 so I'm happy. I can use it without the nagging logo.

@Lee-James First make sure your CPU is not thermal throttling, on beefy systems it can be triggered by inadequate cooling, high multicore usage (like rendering) or memory which is set to XMP in BIOS (which is basically an overclock). You mentioned that your system has fast memory, this fast memory is also pushing your CPU as the memory controller is usually on the CPU die in modern CPU's. Rendering or using your PC for gaming like a flight simulator, are 2 different things. Gaming much more depends on the GPU, and stresses the CPU less than video rendering like Vegas.
If Thermal throttling occurs, your performance goes down, and the chances of Vegas crashing due to the throttling increases, and I am speaking from my own experience. I am not saying this is your issue, but surely something to check: this is best done by running the free app HWiNFO64 which will readout all your sensors, and inform you about pretty much everything, including individual Core thermal throttling.
If you do throttle during heavy rendering, then you need to improve your cooling and/or put some limits to the CPU power draw in BIOS or lower your memory speed.

Yes Bitman is right about thermal throttling. When I started using the trial of V23 to test the new AV1 codec which is my go to export, I found the template only allows CPU encoding despite the GPU having NVENC hardware encoding. My PC fans ran at 100% with the CPU (i9 13900K) using all 24 cores. Using HWinfo64 I could see max temps were 85-90C and that is with a 420mm water Cooler. I like to use Happy Otter Render + to render AV1 using the GPU, it runs 2-3x faster and much lower temps.

Modern CPUs may not throttle until 97C or even 100C+ so even temperatures of 90C on all cores don't necessarily represent a problem.
