just found this, have you heard of framepack?
it only focuses on generating the next frames so video length isn't restricted by VRAM anymore.
you might want to look into it.
I was looking into ComfyUI workflows and here's some info:

Thanks!
Will look into it when I can.
Just to make my previous statement clear and not mislead anyone (there's enough of that on all forums...): I wasn't talking about video rendering, but about still 3D images.
That said, from the little I know about how GFX rendering works with all things, it's probably the same: each task's various subroutines are calculated in parallel, so everything has to be in the GRAM at the same time. Exceed the GRAM limit - and the entire task fails.
The FrameWork you mention, and the way you explain it works, seems to validate what I say: they cut the entire clip into the smallest pieces they can (individual frames) so you can use much less memory.
And though I can imagine it gets a hit speedwise (no parallel-processing of multiple frames), at least it doesn't fail.
When you know your limits, you can find ways to bypass them.
We have used other tricks in 3D for decades now, because there is always a limit to hardware. Those vary depending on the industry you work in and the kind of job you need doing but are always there.
