Hi all, I’ve been trying to get this to work myself and getting very confused by all the posts (most I couldn’t understand so couldn’t get to work). Thought this might be of use for you all reading this.
You can develop your video specs using Google Video Player Developer link below ([https://developers.google.com/youtube/youtube_player_demo]
Just paste in your youtube web link in and then turn off and on options of what you want (e.g loop, modest branding etc) and this automatically generates code that your can paste in Webflow html embed box. However, please note for the looping to work you have to set-up a playlist in Youtube (even if it’s just the one video) and then use the playlist ID dropdown menu. You do however still get a flicker of youtube branding when it starts to loop each time.
