Types of Events

Notes on video complete event

• Create a state object for each individual video component
• Measure the amount of time each video component was in view
• Every time the video component gets out of the view, check how long the component was in view as opposed to the video's length to infer video watch time
• Subtract the gross duration of all seek events (if any) from the watch time
• If video watch time is over 80% of the video length, log the video_complete event
