<p>Did you apply the Optical Flow to a nested sequence that contains a transition?  This looks to me like Optical Flow trying to invent new frames to fill in the slow motion and getting confused by the fact that a transition is blending two different videos.  You should apply your time remaps to the base clips and then do transitions on top of the already adjusted clips.</p>

<p>I rendered a video using Optical Flow (it includes lots of Time Remapping). Basic cuts look as if there was a short glitch-like transition between them.</p>

Welcome! It isn't clear what you are asking. Could you expand your question and perhaps post a sample video instead of just screen shots?

What it's doing is trying to optical flow between the two scenes. You may have to render out the clips individually with 1 or two frame "handles", and then trim them back down.
