Quality Comparison: Full-Body vs. Half-Body(like the example in readme)

[mohamedalaam]

I want to apply lipsync to a video where the entire body is visible (head to toe). However, when I tried this, the quality wasn't as good as with a half-body video, like the example in the readme. Has anyone else experienced this or have suggestions on how to work around it?

I think the issue might be that cropping the face from a full-body frame results in worse quality than from a half-body frame (though I could be wrong). Is there an option to process just the face part to avoid losing quality
