Video Element

Note:

• The externalUrl must be accessible.
• Only H.264 encoded videos are supported; HEVC (H.265) encoded videos are not supported.
• The sourceDuration field must match the actual duration of the source video file.
• The sum of startInSource and duration must be less than or equal to sourceDuration.
• In most cases, startInSource is 0. It only differs from 0 when the video node has been trimmed from the front of the source video.
• When startInSource is not 0, you should set isFrontTrimmed to true to indicate that the video has been front-trimmed.
