I recorded a theatre performance two days ago. Most of the recording was fine but in a part of it there was one person performing with a photo collage on a screen background and also a map in another section of the recording. This resulted in zooming in and out on these parts of the performance. The problem is similar but worse than this one: https://discussions.apple.com/thread/8259180?sortBy=best
I really don't know how to correct the sections of the mp4 output file of this recording. This problem is shown in the link below. I believe Intelligent Auto or Background Defocus (Defocus and not Clear) was the root cause of this problem.
I normally use DaVinci Resolve for post processing, but I could not find a function in the software to fix this.

Many thanks for any advice.
