Videos are inserted using the video tag and by referencing the directory that the video is in, in the same way that you would insert an image or a GIF. However, videos allow for more advanced control beyond playing and pausing. Take a look at the Scripting Reference for more information on manipulating videos through scripts.
<video src="resources/videoName.mp4" />
Users can start and pause a video by tapping anywhere on the video. They can also seek to a particular time by dragging the seek cursor back and forth. As an author, you can enable or disable these controls, or use buttons and sliders to manipulate the video. See the Scripting Reference for a complete list of video elements.
At this time the video tag only supports MP4 file types.
