Live Event Slate

Configure the placeholder video shown before, after, and during gaps in a live event.

Slate may either be:

  • Automatically Inserted: Slate will be automatically triggered under the following conditions:

    • Pre-Event Slate: Prior to the start of a live event.

    • Post-Event Slate: Directly after the completion of a live event.

    • Ad Slate: During an ad break when ad content is not being received.

    • Missing Content Slate: During a live event when both of the following conditions are true:

      • The Live Slicer is not producing content.
      • The live event is not in an ad break.

      Define default pre-event, post-event, ad, and missing content slate from the Slate page. You may override this default configuration when setting up your live event. Additionally, a live event's pre-event slate may also be manually set from the Live Events Dashboard prior to the start of the live event.

  • Manually Inserted: The Live Events Dashboard allows slate content to be manually inserted during a live event by selecting the desired asset from within the Live Events Dashboard's Switcher pane.

    Key Information:

    • Slate that is manually inserted into a live event is known as mid-event slate.

    • Prior to the start of your live event, you may select a CMS library for mid-event slate through the Mid Slate Library option from your live event's Config tab. The assets associated with that library will be available for selection when inserting mid-event slate during a live event.

    • If you enable the VOD Replayable option on your live event, our service will generate an asset through which your live event can be replayed as on-demand content. Each time you insert slate into your live event, you must choose whether that asset will contain the slate content being inserted.

      • Include slate within the VOD asset generated by your live event:

        1. Open the configuration for the desired live event and set the Enable Slate in VOD Replay option to Yes. You cannot set the Enable Slate in VOD Replay option to Yes if a live event has been configured to use slate from a CMS library shared with your account.

        2. From the Live Events Dashboard, find the desired asset under the Mid Event Slate section and click on Save to Replay. Use the Save to Replay option to include the entire mid-slate asset within the asset generated for VOD replay of your live event. This occurs regardless of whether the live event operator chooses to add only a portion of that mid-event slate asset or loops it multiple times. If the live event operator loops a mid-event slate asset multiple times, it will be included only once for that instance of slate.

      • Exclude slate from the VOD asset: From the Live Events Dashboard, find the desired asset under the Mid Event Slate section and click to the left of the Save to Replay cell. If the Save to Replay cell is not present, you may click anywhere on the desired asset.
