I just made some try here

https://m3p2.ljbac.com/m3p2/courses/blob/master/00.brainstorming-pedagogical-teams/40.collection-existing-pedagogical-content/04.reference-frames-coordinate-systems/situate-on-earth/cheatsheet.fr.md

But on my full local web-site, such video causes big problem, until I remove the file.

If possible I would like, resize, make autoplya and loop, mute and not able download (same for images, possible to prevent from downloading?)
