Mini 3 Pro Video Issue

[barnabyd]

Hi, my name is Barnaby. My son and I enjoy flying and fixing DJI drones in California.
I fixed a gimbal for a customer on their Mini 3 Pro (replaced the pitch motor and the roll bar) after they crashed it. The customer has it back now. It has no errors but the video is strange (linked below). They sent me a sample. Not sure if it's jiggly or skipping frames or what. It reminds me of heat waves in moist air but I don't think that could be happening that close to the subject of the video in this very dry climate. Has anyone experienced something similar and has any advice? TIA

It looks like every few frames the image stretches and then returns back to normal on the next frame. See attached.

Possibly Atmospheric heat shimmer not much you can do except use an ND filter.

I might be wrong, but it looks like the infamous "jello effect" which is usually caused by vibrations in the drone causing a strobe effect with the video frame rate. If the vibration is caused by faulty props (or imbalanced props), an easy fix is to replace all 4 props with brand new ones. Here's a "before and after" video illustrating this problem and its fix:
