Consistently horrifying smear face when head is tilted back

Post by unkempt »

This pic is from a transition where the head is tilted pretty far back. On the right, you can see the distended blob that it became which is what always happens when I do faceswaps from any source video. I doublechecked my face b pics and alignments and they seem fine. The alignments on the source seem fine. I don't know what's going on. I've tried Realface (600000), Villain (400000), and Dlight (250000), but no luck.

I'm also having a weird problem with one eye being open and the other closed...

At several points during this video (haven't seen this issue before - or wasn't too noticable), the eyes are looking in the wrong direction or one eye is weirdly closed when it shouldn't be.

This occurs because you don't have enough/any data in B representing this angle, so the model cannot swap it effectively. If you look, A can recreate this fine, B cannot. That is due to insufficient data covering that pose.

2 options:

  • Get data for B that covers these more extreme poses
  • Avoid using such extreme poses in your final video.

re: eyes. These can be tricky, Some models handle it better than others. I know that dlight + realface can have issues with eyes. It may be down to the unbalanced nature of the models, it may not be.

I don't have such a direct solve for this one. Generally ensuring data covering eye directions wouldn't hurt. However why a model may learn that eye direction is one way for the A side and different for the B side I couldn't say due to the 'black box' nature of Machine Learning

Fair enough. So I need more source material with that angle. You're right that it's model-dependant on the eye thing though. I've only ever seen that dlite.
