CasparCG is open source graphics software made by the Swedish Broadcasting Corporation.

First Setup

CasparCG can be downloaded from here. The zip file should typically be extracted to within c:/casparcg on the target PC, after first deleting any old copies of CasparCG server.

Inside the extracted folder should be a file CasparCG_Server.exe (located near to casparcg.exe). If this is missing, it can be found in an earlier release of CasparCG (as of April 2015, it can be found in 1.0.6), and placed into the correct location.

CasparCG_Server.exe can then be launched to configure the application.


Upon launch you should be presented with the following window. If any alert boxes talking about 'ArrayIndexOutOfBounds', click continue and resume use. Sometimes this alert does cause a restart of the application to continue to run properly.

After a few seconds the online text should appear, which means that the application has launched successfully and is ready for configuration.
