And if you leave only the mp4 version (leave the webm field empty), does it work on Chrome?

Try hard refreshing the content in Safari

hold Cmd-Shift-R or Shift-Reload.

Hello Michelangelo,

so here is the thing :

1. it takes a while to download the video file. Because of that when the download finishes the preloader has little time to actual display, it will just show for a fraction of a second

2. self hosted videos (especially those in hero section that autoplay) should have a recommended size of up to 10Mb

3. for video shortcode/widget we can change the preload attribute to 'none'

indicating the the video should not be preloaded but instead starting to buffer when you start playing. If you really want a big video file and you don';t need pre buffering we can change that if you provide wp admin access with full access to plugins file editor.

This does not affect video files in hero section as they autoplay and autoplaying has precedence over preload:

Hello Michelangelo,

first and foremost we change the preload attribute for the self hosted video shortcode that you have here, at the very beginning:

Now, at least theoretically the browser should not wait for the whole video file to download, it should start buffering when the user starts playing. Make sure you also clear your cache first.

For videos in hero section this does not apply. for the reasons I've already mentioned.

But this is the timing I got in your home page:
