As I'm having difficulty accessing the video:
(I still seem to have lots of issues trying to watch videos in the browser. Even embedded Vimeo never works for me (Chrome/Debian/Linux), seems flash video is the only thing that consistantly works).
{position: sticky}
It can be used to make sticky-headers like iOS lists have: e.g. showing the letter of the alphabet at the top of the screen when scrolling through an address book .
It will be really useful for keeping the row titles visible in a long scrolling table.
There's a time and a place for this sort of thing. I personally get a little annoyed with fixed headers as it can break text paging. Text gets hidden under the header. When you hit page-down you get another page worth of text but the fixed element obscures the text.
Can position: sticky help with something like that?
That should download the file directly, and you can watch it in a native player.
That one is a little too large a video a file size for my tariff, will have to watch later.
