Widget:Snippet

This allows you to embed MP4 videos as if they were a normal GIF. You use it like this;

{{#widget:Snippet|file={{filepath:TestingMp4.mp4}}|width=300|height=300}}

Where you replace 'TestingMp4.mp4' with the name of your video file. Width and height are optinal.

It will automatically mute, autoplay, and loop the video, just as if it were a GIF.
