Must Make Delayed BG video PLAY after page load

I have a loading container that fades out after page load is complete. This is approximately 1500ms.
I must get the BG video to play only after the page is loaded. The bg video is about 3.0MB.

  1. Load Page for first time
  2. Load Splash Loading Container
  3. Video Plays after page is finished loading

OR

  1. Manually set BG video to start playing at 1500ms
