There a few reasons why there might not be video in your LiveCut Editor session. It could be an issue on the source stream, that the team responsible for the stream will need to resolve. Or it could be an issue that you'll need to escalate to SnappyTV Support.
We've developed a simple testing tool to help you troubleshoot this issue. Please click on the 'Stream Issues' button at the top of your LiveCut session to be taken to the tool. For guidance using the tool, please use this guide.
