Is There a Way to Deflicker Videos in Topaz Video AI?

To explain what I mean, I’ve uploaded a short excerpt from my video, unlisted on Youtube:

The brightness oscillates in a rhythmic pattern. I think Youtube changed the video framerate, but the original was 50 fps, and the oscillations are in cycles of 6 frames, so about 8Hz.

What you would call this? And what tools can fix it?
