I'm not sure if I could actually hear the engine slow in the video.

At this point, I wouldn't worry too much about it unless it is a chronic problem all the time, cold engine right after start up, warm engine waiting at a stop light, in gear, in neutral, etc.
It s a chronic problem, it comes in all different time when the car doesn't run, cold engine warm engine there is no difference .
