Is this your SD card footage or cache on device ?
As it happened when you turned, your antenna might have just hit something bad I think, but connection issue could have caused bad record feed if it was the cache recording shown above.

Does it do this in other locations ?
It looks like strong interference to me, possibly wifi or magnetic / power lines etc.

If it does it every location, including well away from homes or anything like electricity transmission lines and metal objects, it could be a an issue with the camera or other on board part that affects recording to card.

SD card write rate could be too low.... (I'd say the card should be rated at least 60 MBit/s; there's a recommendation list on DJI website)

It happens even in cache, I will experiment with better memory card.
