While running the workflow I'm getting
The size of tensor a (41472) must match the size of tensor b (36864) at non-singleton dimension 1

How can i fix this?

Probably mismatch with the input video size/length and the generation resolution/frame count.

I ran into this issue too, but I figured it out!

Just don’t use the “Load Video (Upload)” node from ComfyUI-WanVideoWrapper—switch to the built-in “Load Video” node that comes with ComfyUI instead. That fixed it for me.

I asked an AI about it, and it’s probably because FlashVSR uses a lot of BF16 internally, which can cause compatibility issues. Hope this helps!
