Question

Lip Sync is slow

It seems that the lip synch is a second or so behind the audio when I record a video or use CA with zoom. 

Any ideas how to fix this?

thank you

If you're using something like Wirecast/OBS, you can delay the audio so that it lines up with the lipsync. If you're not, the best thing you can do is reduce your audio buffer size in the Preferences.

In this attached screenshot, the default value is 512. This refers to the "chunks" of audio that the Lip Sync behavior analyzes to then show the mouth shapes. By lowering that value, the latency is reduced. On a 2018 Macbook Pro, I was actually able to use 16 samples and record it without issue.

Thank you. I am on widows and the lowest it will go it 30. It seems a tad bit better, but not perfect.

Thank you so much for the video how to make a zoom video. My students loved it!!

Since I've seen that this is a common question, I'll make a tutorial on using OBS. It's more complicated, but it does allow you to do this so your quality can be better.
