RudderStack's video specification lets you define how a customer engages with your videos and the related ad content.

This documentation lists the conventions and best practices for sending events in case of video tracking videos. It will also clarify the overall structure and classification of these events.

Not all RudderStack destinations support video tracking. Refer to the individual destination's documentation to check if it supports this feature.

This guide is organized into the following three event categories:

  • Playback
  • Content
  • Ads

Playback

The playback events are associated with the actual playback of the video content and track the information about the video player.

For example, when a customer plays a video on your app, a Video Playback Started event is sent along with a unique session_id. All subsequent events generated from this session are tied to this same session_id.

Suppose if you have a web page with two video players, you would have two separate sessions and session_id associated with them. On the other hand, two separate videos played on the same video player would still constitute a single session with two contents associated with it.

All the playback events are tracked and recorded at the session level.

Playback Events

This section details all the video playback events.

For more information on each of the properties associated with these events, refer to the Playback Event Properties section.

Video Playback Started

This event is associated with the user action of pressing the play button on the video player to initiate the video playback.

A sample event is as shown below:

  • User starts and completes the second content pod
All of these events within the flow happen within one video playback.

FAQ

What are pre-roll, mid-roll, and post-roll ads?

  • Ads that appear before the start of the video playback are called pre-roll ads.
  • Ads that appear in the middle of the playback are mid-roll ads.
  • Ads that appear after the video playback are called post-roll ads.

These ads can be a promotional video by the sponsors or a piece of content offered by the content provider.
