.......................movie speed too fast??
(for webp download to win10 run webp animated viewers,the movie speed are more slow and movie work good)
i check for win 10 webp players,the webp speed not too fast
so it is hard to speed balance for win10 <---> firefox/chrome :(

just play it yourself instead
