Generated video are noisy and pixelated

[moserello]

I've an issue with the model on my Apple Silicon M1. I run it using the ComfyUI Integration.

For all the tests I've used this example prompt:
A woman with long brown hair and light skin smiles at another woman with long blonde hair. The woman with brown hair wears a black jacket and has a small, barely noticeable mole on her right cheek. The camera angle is a close-up, focused on the woman with brown hair's face. The lighting is warm and natural, likely from the setting sun, casting a soft glow on the scene. The scene appears to be real-life footage.

All the generated videos appear as random moving pixels. I used 30 steps generation, 768x512 size, batch size=1, cfg=3, max shift=2.15, base shift=0.95

Here's an example of the output. All videos that I've generated are pretty similar

ComfyUI_00001_2-ezgif.com-webp-to-mp4-converter.mp4

Generation is slow but it run without any error
