Controls not taking up the full width: idk if I like it or not. They are probably nicer for super-wide screens? Definitely hope things like embeds or 4:3 videos would still be reasonably sized.

Controls being higher up: don't really like that; I'd prefer them being as close to the bottom edge as possible, to block as little of the video as possible.

Blur instead of tint: idk for sure, might be slightly too resource-intensive for some older devices? The tint is just basic alpha-blending, after all.

Also, where would chapter names fit in the newer design? In the older one, they are just to the right of the timestamp, but the new one has a lot less space, so some longer chapter titles might get cut off?
