Well, "video" ain't quite right. The image that was used in that clip was clearly stiched together from probably two separate images which can be seen by the identical sharp change in color at the 10- and 33-second marks AND the much more subtle color changes that can be seen at the 20-second mark (this one was created with several horizontal breaks in part to "preserve" the continuity of Perseverance's top where the slight change in image angles between those shots would have caused noticeable "breaks" in the gear atop of Perseverance).
I'm uncertain why the creator chose to jerkily move the camera view--I'm fairly certain that Perseverance's camera arm is capable of MUCH smoother movements--except that perhaps the maker purposefully intended to simulate a human holding a video camera and slowly turning in place.
The sound is likely also partly simulated. The audio could be taken from one of NASA's videos but my guess is that maker at least added what sounds like a person stepping in place on a crunchy surface in order to turn. For that reason I changed the above paragraph: I believe the maker did this deliberately.
