What If My Live Event Ends Early Or Goes Long?

Last Updated:April 21, 2026

Live events rarely follow a perfect schedule. A meeting might wrap up well before its scheduled end time, or it might run over into the next block of programming. This article explains how to handle both situations in Cablecast.

Control Rooms and the Force Matrix

The steps in this article can be performed from either Control Rooms or the Force Matrix—both provide access to the same device actions and routing controls. Control Rooms is the recommended approach. Unlike the Force Matrix, Control Rooms let you build focused interfaces for specific events and create Macros that can perform multiple steps in a single click—including starting and stopping recordings, switching outputs, managing captions, and sending Autopilot. For details on setting up Control Rooms and Macros, see Getting Started with Control Rooms in Cablecast.

If Your Event Ends Early

When a live event ends before its scheduled time, there are a few critical steps to take: switch your channel back to the bulletin board, stop captioning, and stop the recording. If you use live captions, stopping transcription promptly is especially important—Cablecast will continue sending audio to Cablecast Cloud Services to generate captions even when nothing is happening, which consumes your caption minutes.

Step 1: Switch to Cablecast CG

In Control Rooms (or the Force Matrix), locate the device that handles your CG output and use the Action button to choose Play CG, then click Take.

Which device to use depends on your system configuration:

If your CG output is shared with your programming output, start CG from the VIO Playback device. If that output isn't already routed to your cable channel, select the appropriate output before clicking Take.
If your station has a dedicated 24/7 CG output (whether from a standalone VIO CG server or a dedicated output on a VIO 4, VIO4+, VIO 2, or VIOLite), CG is always running on that output. To return to your bulletin board, route that output to your cable channel.

Step 2: Stop the Recording

Click the Action button next to the VIO Record device and choose either Stop or Stop Recording—both do the same thing. Click Take. The file will begin processing. If the recording was configured with a File Key that matches a Show Record, the file will automatically link to that Show Record when processing is complete. If not, the file will appear as an unlinked file in Assets, where you can create a new Show Record from it.

Note: Stopping a recording also automatically stops caption transcription, so no additional step is needed. The one exception is if your live event was captioned but not recorded—in that case, use the Action button to choose Stop Transcribing and click Take to stop transcription and prevent further use of your caption minutes.

If Your Event Runs Long

If a live event is running over its scheduled end time, you need to override the channel output to hold the current source in place and extend the recording before the next scheduled program begins.

Step 1: Override the Channel Output

In Control Rooms (or the Force Matrix), click the Channel Output button while your live event is still in progress. Cablecast will ask if you want to override the schedule on the channel output. Click Take.

The video server output will display Overridden next to its name, indicating that the channel will stay on the current source until you resume automation. This prevents Cablecast from automatically switching to the next scheduled program while your event is still running. If a recording was scheduled as part of the live event, the override also applies to the encoder, so the recording will continue past its scheduled end time until you stop it manually.

Note: While the channel is overridden, the Main Menu will also show the channel name followed by (Automation Overridden) as a reminder that the override is active.

Step 2: Resume Automation When the Event Ends

When the live event is finished, go back to Control Rooms (or the Force Matrix) and click the Channel Output button again. Cablecast will ask if you want to resume the schedule on the channel output. Click Take. The column will no longer be highlighted red.

Send Autopilot again to return to normal scheduled programming.

Step 3: Stop the Recording

Click the Action button next to your encode or VIO Record device and choose Stop. Click Take. The recording will stop, and the file will begin processing.
