I tried to optimize a 15 second 4K clip because it was noisy.
Output in H264 hight quality.
I have a 12 Gerneration i9 K12900K processor, 32 GB Ram and a NVIDIA GeForce 3070 8 GB
At about 2/3es of the rendering, the computer collapses suddenly and I have to restart.
Not good. Unsuable this way.
this sounds a bit like a system instability. please check your power supply and maybe lower the maximum power usage of your gpu via msi afterburner. 
Besides that I have no idea what you mean, I have never had this problem and I am editing 4K videos continuously with Edius from Gras Valley.
Edit a video is a bit different. Video a. i. takes your graphics processor and cpu into a continous high load and this maybe for hours. Temperatures of your PC components might rise to high levels.
Yes, I understand, but I edit 4K videos all the tome for many hours a day.
But ok, I will try it again and will observe the processor temperature.
Editing a video does not put your hardware onto a continous heavy load like video a. i. does. Video a. i. tends to be a bit stressy for the hardware, especially on hot days like today (28 °C at home).
OK, thanks, understood.
I will try and see what it does or what I can do to keep the temperature down.
My M1 Studio Max and M1 mac mini have also been doing something like that lately.
They also no longer allow me to render previews…
Hi @dieter.knuttel I moved your thread to the correct section.
I am so sorry to hear that. In order to troubleshoot this, I will need your logs and your full system profile.

Hi,
I have attached the file you were asking for.
I appreciate any help.

Thank you
I have taken a look at your system profile and see that your driver is quite out of date, let’s start off by updating the device.
We suggest updating your graphics card by using these steps:
Go to the NVidia Driver Download Page.
Enter in the information for your NVIDIA GeForce RTX 3070
In the search results, you will want to use the Studio option.
OK I did this. I downloaded it and installed it.
I tried to watch the CPU temperature, but it seems that I do not have the right program for it on my computer.
I test rendered the same file as before, and again, after 2/3 of the rendering, the computer crashed
What program do you have?
If you are using Task Manager it is important to note that Task Manager is not the most reliable source of information for GPU and CPU consumption. To get a better idea of how the app is utilizing your GPU, you will want to switch from 3D to Graphics_1.
Can you post your logs?

Hi,
I used HWMonitor, but could not find the display for the CPU temperatures.
Can you suggest an app for that?
But I think it is very propable, that it shuts off because of heat.
I do not know what you mean with
“switch from 3D to Graphics_1.”
II update to version 3.4.0 now.
Find attached the requested log file

Correction:
I have updated to v3.4.1
Hello,
Your initial assumption, that the computer is getting too hot seems to be correct. In light, I was wondering, a slow motion seen in the editing program, videos from Gras, Valley, and here. Also, the computer crashed.
I will try to cool the computer down with a big fan during rendering to see, if that helps to solve the problem.
Hello,
I dictated the last message and something went wrong.
Here the correct meaning of my last email:
Your initial assumption, that the computer is getting too hot seems to be correct.
Tonight I was rendering a slow motion scene in my editing program, Edius from Grass Valley, and there also, the computer crashed.
I will try to cool the computer down with a big fan during rendering to see, if that helps to solve the problem.
Hi,
One I’ve tested it with the fan now.
And it worked.
Rendering slow motion and also topaz AI could complete the rendering process without the computer shutting down.
Good.
I love the simplicity of pointing the fan at the machine! I am glad that this is reducing the overheating. You can also enable low power mode which should help! This will be found under File > Preferences menu
It was a test with the fan.
I made another test without the fa but with the open computer and also then it did not collapse.
So not a big problem any more.
Thanks for the support.
