How to keep silent

[NewNoviceChen]

During the synthesis of video, I found that if the original video was not in the silent state, there would be a problem of mouth mismatch, but in the silent state, the effect is much better. I would like to ask how to match the mouth shape in the original video speaking state, or directly generate a silent video (I found that the effect of Wav2Lip trying to silence is not good), thank you very much
