While rendering animation, Blender crashes when I use a video of fire as an image plane. If I disable them, it renders fine. Does anyone know what’s happening here? I’ll attach the crash log if it is of any use.

Does it crash immediately no matter what or at a certain frame?
What happens if you keep the planes but remove their material (to make sure it’s the material and not something about the meshes).
Does it crash if you try rendering in Eevee?
Disable the BlenderKit addon and see if things improve.
I tried that. It didn’t work.
The crash is random. Once it crashed at frame 88, and if I tried to continue, it crashed instantly.
I didn’t try deleting the material, but I’m pretty sure it has something to do with the video textures.
I didn’t try rendering in Eevee. I want the render to be in Cycles.
It’s almost certainly a VRAM issue- you’re trying to load gigabytes in and out of VRAM every frame, and because it’s a video, you have to load the entire thing every frame, which is a huge load. Try converting your video to an image sequence so your GPU only has to load a single frame per rendering frame
I know that and am not suggesting to switch renderer for the final version. I suggested this as a test to find if the problem is specific to something in Cycles, to help narrow down the problem. One other thing that I might have thought to try is to render some frames on the CPU (at low samples) to see if it’s a GPU problem.
But I agree with @joseph, switching to an image sequence is the thing to try first.
