kijai, thanks a lot, it works like a blast from the first try (ubuntu A100)

I got MUCH better results with XDPM then with DDIM

found this in their docs:

We recommend using CogVideoXDDIMScheduler for CogVideoX-2B.

# using `CogVideoXDPMScheduler` for CogVideoX-5B / CogVideoX-5B-I2V.

indeed, see below

Technically it is better yes, but in reality I find it varies on the task. Different schedulers should absolutely be tested and my defaults aren't really meant to be universal defaults. Thanks for sharing this comparison!

@ptits hey, do you notice that "speed" of animation is different between DDIM and XDPM? I find that XDPM(default) is more natural on 24fps, and DDIM is like 2-3 times faster.
