I received a customer inquiry about using a live video as the background behind lyrics. While I didn’t plan for that feature in Harmony 1.0, I found that it was easy to implement using Harmony’s support for Quartz Compositions.
To use live video as a background in Harmony, download the LiveVideo.qtz file and drag it into Harmony’s media browser. Once the media browser refreshes, select the LiveVideo.qtz and click “Set as Background”.
Caveat: If you have a built in iSight camera, you will need to disable it since the Quartz Composition will prefer to use it. I found this AppleScript to be very useful for enabling/disable the built in iSight.
Caveat 2: You should match the aspect ratio of the camera to the aspect ratio of your projector to avoid the image being stretched.
