I created a little test for this, and it appears to me the lack of autoplay comes down to the browser.

Video-Autoplay.rp (58.5 KB)
I’m running a computer with Win10, default browser is Google Chrome.
When I preview this from Axure editor, it works and video autoplays.
When I publish HTML locally, the video loads but does not autoplay.
When I publish to Axure Cloud, the video loads but does not autoplay.
When I play from the Axure Cloud desktop app (which is actually a Preview of the pages) it works and the video autoplays.
I tested the prototype on Axure Cloud site on my desktop with latest Firefox browser, and it worked.
I tested the prototype on Axure Cloud site on my desktop with latest Edge browser, and it worked.
I tested the prototype in the Axure mobile app on iOS 13 and it didn’t work, the video loads but does not autoplay. This is due to Apple policy that videos do not autoplay–the video player’s play button must be pressed.
I tested the prototype on Axure Cloud site in Safari and in Chrome browsers on iOS 13 and it didn’t work.
There is a chance this could work using javascript injection into dynamic panel or other widget directly on the page–that might bypass browser policies for videos in popup/inline or untrusted domains? I’ll try this if I can find more time.
