Update: I have uploaded a new version of the video, this time in OGV. Observations:

*The video now plays with acceptable performance in Firefox and the Wikipedia App on Android mobile
*The video doesn't play at all in the default Android browser, nor in Chrome on Android
*On desktop, the video doesn't automatically increase the quality of the file download when a user maximizes the window, meaning that a user who clicks the thumbnail on ENWP, gets the popup, then clicks maximize will likely see a file that looks awful when full-screened until and unless they find the button to increase the video quality.
*On IE on desktop, the default popup for me is for 360p even though that's smaller than it should be for the size of the popup that I get, so the video quality in the popup is poor. The popup should be for 480p.
*I haven't tested iPhone and Mac desktop browsers

Between VP9 and OGV, I'd say that our support for video playback has much room for improvement on both desktop and mobile.

Can we use this situation as evidence that WMF resources should urgently be directed to improving end-users' video viewing experiences on mobile? (:

err. nevermind. TMH selects the vp9 as the best possible source on my
phone for some reason, so it probably does the same for you too.

The chopiness might not even have anything to do with vp9 so much as
the high bit-rate of the original source being too much for a phone or
something, although hard to know for sure. The VP8 1080p transcode
behaves rather chopily on my phone too.

All I can say for sure is that the webm VP8 480p transcode plays
nicely on my kind of oldish phone. The VP8 720p is a bit choppy but
not too bad.
