In addition to its common properties, the video element has several properties of its own.
|duration||media||Identical to duration from the common properties, but with the addition that it can be set to media to make the element as long as the source video.|
|source||null||The URL of an video (an mp4) you want to display. If it was uploaded using the template editor, it may also be its internal GUID.|
|trim_start||null||Trims the source video to begin at the specified time (in seconds) rather than at the beginning.|
|trim_duration||null||Trims the source video so that it stops playing after the specified duration (in seconds) rather than at the end of the source video.|
|loop||false||When set to true, the video starts over when it reaches the end. This property cannot be used in conjunction with the trim_start and trim_duration properties.|
|volume||100%||Adjusts the volume from 0% to 100%. Set it to 0% to mute the video.|
|audio_fade_in||null||Fades in the volume for the specified duration (in seconds) at the beginning of the video clip.|
|audio_fade_out||null||Fades out the volume for the specified duration (in seconds) at the end of the video clip.|
|fit||cover||This property specifies how the video should be resized to fit the element. It can be set to cover, contain, or fill.|
