I had the same issue when I had low signal strength to my controller @ about 2300 FT out. I upload the logs to phantom help and there is about 10 seconds missing (see link below).
I was going to start a separate post but this thread showed up when I types the new title. Anyway, my initial concern was the gimbal twitch was due to low signal to the controller or bird strike, but after seeing your video my concern is there may be bigger issue.
Does anyone have any insight into this issue?
My equipment:
DJI RC (v01.03.0700 firmware) Mini 3 Pro(v01.00.0700 - most current)
*realized this morning that there is a new firmware for the RC
Video segment from 19 Dec 2023
Log - missing 10 seconds starting at 5m 35.3s where the gimbal glitched
