Drone MOV file very sluggish when scrubbing as well as zooms in during scrubbing.

Hi,

I'm trying to edit my MOV footage from my DJI Inspire 1 drone.

I had to have the footage repaired and have now imported it into PP.

When I attemp to scrub through it to find the sections of the clips I want, the footage enlarges by a fair amount to the point I cant tell where I'm at. When I stop scrubbing, it resizes back to frame rate.

I have tried rendering the entire clip but no change.

Any thoughts on how I can fix the problem?

Thanks.
