Hey this answer is a little late, but better late than never right?

I think you’re talking about exposure compensation with the -3 to 3 adjustments. You can adjust this in the video mode the same way that you described (hold down AV button and rotate dial).

Trick is that you need to make sure the Movie Exposure is set to Auto (press the Menu button, it’s the first item).
