Re: SC 2.2.2 Pause, Stop, Hide - meaning of "starts automatically"

The word "essential" is subjective. It's usually obvious if something is essential, but not always.

And you can only update a percentage value if you know what the total is. The percentages shown for file downloads and installations are calculations that make certain assumptions (such as the bandwidth never changing) that may be incorrect. In other cases, such as for a page or content loading indicator, the expected time is completely unknown, so the percentage completion cannot be calculated.

I think video would be covered by the clause "unless the movement, blinking, or scrolling is part of an activity where it is essential".

You can show progress without continual movement, for instance by updating a textual percentage value. This doesn't convey a sense of motion which is what is meant by "moving, blinking and scrolling".

Isn't that exactly what is stated in the clause "unless the movement, blinking, or scrolling is part of an activity where it is essential"?
