Huge video - Slow loading time

[pmeenan]

I'd strongly encourage not setting the video to autoplay. Most players have an option for a static image that they can display until the user clicks to play (you don't need to manually load your own image and trigger the playback, it is supported by most players out of the box). My suggestion isn't just because of performance reasons but for user experience. If a user loads your page in a background tab then the video will start playing before they even actually look at the page. Users on metered connections will also have to pay for the bandwidth of the video as well.

If you do need to keep the video as an autoplay video, you can look to see if your player supports buffering only part of the video and using byte ranges. That way it will only download the first part of the video and it will download more as needed.
