Proclaim uses Windows Media Player to show present and play videos, and for a long time this has come standard on Windows computers.
However, some newer versions of the Windows operating system don't come with it, which has left some people unable to play videos in their services.
As a result, we've included a new media player with Proclaim 4.11. This will allow you to play videos in your services.
To enable it, navigate to Settings > General, then choose Use new Video Player. You'll need to close and relaunch Proclaim for the setting to take effect.
