I have been able to do this in the past, but only by exporting the entire video as a series of images and the audio as a. I would like to remove these duplicate frames so the final video actually plays faster during these times, and at the same time remove the quietest audio adjacent to the removed duplicate frames so the audio does not go far out of sync. Because they are simulations, even when well-optimized there are often framerate drops when the simulation becomes too computationally intensive for the hardware.
