Hello, it’s not that obvious from the video, but it’s possible the retarget pose for fingers are more misaligned as you rotate more of the clavicles. Make sure the retarget pose for fingers matches both side. For example, the thumb alignment can be very easy to miss. The idea of retarget pose is to make sure that is the same pose in both side. Make sure they align horizontally. Also you can compare with Audio2Gesture base mesh retarget pose, which will be the best way to match both side of the pose. You can’t edit Audio2Gesture base mesh retarget pose though, so you’ll have to edit the retarget pose of your mesh.
