Thank you very much for your replies and I apologize for the late response - I did not have access to my laptop for a couple of days.

HDRI:

By the way, just a quick question. The character in my main scene is 3 times as big as a human (human metarig for example) and all my other scenes are sized up according to the size of my character in my main scene. So, if I reduce the size of all scenes by 3, do you think this would help significantly or just a small difference it would make?

I guess as you suggested I will render them as images and then convert them to video. In this case, I can at least continue from where it stops after waiting a little bit before I can continue.

I just tried to render as an image sequence but as PNG and it stopped at 224 frames but Blender did not crash. It gave the following error: System is out of GPU and shared host memory.

I will actually try to render them separately as EXR images and then composite them as you suggested. However, will this reduce RAM usage by a lot? I mean, is it for sure that this method will work without any problems?

The render for the last 40 frames is completed without any problems.

Dear Omar,

That is exactly what I did, and that is when rendering the same image was 4-5x slower than before loading factory settings.

This is a file for my NFT collection so I hope it won't be a problem for me for posting here :)

Dear Omar,

By the way, this is the latest crash information.

Hello Omar,

By the way, the crash always happens somewhere between frames 200 and 240. I have an 10 second animation with 240 frames.

I'm also having a crash problem. I just got a new laptop with R7 5800H CPU, 16GB RAM, RTX 3060 GDDR6

Correction - only twice my renders were completed without problem - one time with 4096 samples and another with 6500 samples. Other than that, Blender keeps crashing before the render is almost completed after all those hours.

Hello, this is my first time here so I hope I'm posting this at the right place.
