It's what I personally took away from it. I was also someone who had the same feeling when I first heard Wayland's "every frame is perfect" mentality. I thought, "This is probably a good idea on multiple levels."

I agree the YouTube example isn't the worst one, but also at the same time, I don't agree with you that there is nothing buggy or janky about it.

There is no logical reason for there to be two copies of the video rendered at once. The video is literally resizing into position, while all of the UI elements shift around it. Why would there be more than one copy of the thing that is resizing?

I will relent on only one thing: "If I take a screenshot of your app at any moment, it must make sense" is too strong of a statement on its own. The context that it is a screenshot of an animation is important, just like cartoon inbetween frames. However, I think if you're being generous with interpretation you can allow this to be implied.

I see what you're getting at, but I think you're focusing on the incidental. An animation is good if it's clear and intuitive in motion. It may often be the case that good animations also look nice in a screenshot halfway through, but (a) they don't always, and (b) working well in motion is obviously the more important of the two goals.

As such it makes no sense to worry about the latter thing - it's not a signal whether the animation is good or not.
