Alpha Key

Hi - we're looking to move away from a popular closed source competitor to OLP after a good experience with it at my previous church but I could really do with alpha channel keying to help make the live stream easier than using luma/chroma key and having to switch the keyer on/off in the video switcher whenever we play a video from the software or show a powerpoint deck. Does anyone know if this is possible at the moment?

Thanks in advance,



  • Hi Matt, currently I don't think there is an easier way to achieve this. Although, transparent background images are supported in version 3.0 when that eventually gets released. If you would like to try the alpha release you can find the download links on the OpenLP blog (these are unstable releases hence the "alpha", experiment at your own risk :smile:).
