Could just be my browser, but it doesn't seem to play very nicely for me ( Firefox on debian jessie ).

First time I tried to hover, it didn't do anything at all, I think it might have still been loading ( or waiting to load the 'live' version until I hover over ).

When I got it to actually go 'live' they didn't seem smooth at all, stuff was jumping all over the place. Though, after watching them both fully, repeat playbacks seemed fine.

didn't get either of these issues in chrome on the same machine.

You have to hover on the 'Live' icon in the top right.

Works fine in Safari :)

Edit: Can confirm it's very twitchy and jumpy in Firefox on macOS. The photo and video switches place every few hundred milliseconds.

Looks jumpy then blurry on a Pixel XL in Chrome. Not at all something I would want to embed. I'm guessing it looks better on iPhone and/or desktop.

Similar in mobile safari, most recent iOS version (10.3.1). They seemed very jumpy, not like my own live photos on my phone.

I'm seeing the same in Mobile Safari though it works normally in Safari on a Mac.

I'm experiencing the same jumpy Live Photos on Firefox for iOS. Latest version of both iOS and Firefox.

Is it only for mobile? Doesn't work on Chrome for desktop (at least not on mac anyway). I'm guessing it's supposed to animate?

I had an issue as well, but realized the Chrome extension 'Disable HTML5 Autoplay' was the culprit.

Mouse over the 'Live' box and it'll play.

Tried that. Clicked on it a bunch, too. Disabled ad blockers for good measure, even.

Works just fine on Chrome from my Mac.
