Videos are very shaky and jittery even with stable shoulders and limited movement #128

Using the workflow that's linked here and one of the driving videos that's in here.

The videos come out super shaky and jittery. Didn't change any settings that's in the original workflow. Anyone have a solution to the problem?

Same for me, what are we missing?

Maxadox commented 1 month ago

Found some YouTube and Reddit comments saying the gradio version of the original repo doesn't face the sabe jitter issues

I found that the LivePortrait Cropper has some default values that aren't the same as the demo from LivePortrait. I've changed the scale from 2.3 to 2.2 and the vy ratio from -0.125 to -0.1. But only for the driving video, the source image stays with the default values.

I found it reduced the jitter effect in my case.

Disable rotate in the croppers works for me to reduce jitter.
