Right now with Sierra even Apple has it's Picture-in-Picture as part of the OS itself. What I don't like is that they require the site to comply to their PiP & at the moment as I'm aware of only Vimeo does that. That aside there are some hacks how to enable it on other sites such as Youtube. [0]

I tested Opera's video pop-out as an alternative to macOS's PiP. What is positive here is that Opera's mode supports most of the video players. Also what I like in Opera's mode is that you can actually control the timeline in the pop-out which seems useful.

But the deal-breaker is when you change focus between desktops (Apple's Spaces). Opera's video pop-out doesn't follow you. Actually you have to transfer the browser window with you on the other desktop in order to have the video pop-out which kinda brakes the point of the feature for me.
