Embedded video from YouTube, has minimal branding, and suggested videos at end from same channel (i.e. not random or competitors!)
Embedded video (MP4) without any controls or branding once it plays.
Embedded video (MP4) WITH controls (on hover) and auto-plays video... because audio is muted.
Note: It's impossible for auto-play videos on a web site which has audio active. User can unmute as you'll see.
