Not continuous frame-lock synchronisation. A small residual delay may remain.

Repeat the moment.
Change the pace.
Set A and B markers on any panel to repeat only the passage that matters. Slow detailed movement to 0.25x, move through footage at up to 2x, or give each video a different playback rate.
