Hiccup when using two - almost identical - driving videos stitched together

Hello,

I'm using a composite driving videos with two - almost identical - webcam recording stitched together. Unfortunately, I notice a clear hiccup at the point of transition (right after the 5 seconds mark):

I found a way to mitigate the effect by adding a fade in / fade out between the two, although the character clearly advances his chin (right after the 5 seconds mark):

Ideally, one should use a single source for the entire driving video. However that's impractical if you want to iterate on section of the dialog without recording everything again. For LivePortrait, could you come up with better interpolation that handles sudden variation in the driving video more smoothly ?
