→ Download the latest release of the Just Playout bundle which includes the most recent version of Composition Builder.
Extract the compressed ZIP archive.
Open the DMG file and follow the shown instructions.
Optional: Install the → Template Package afterwards.
Upon completion of the installation procedure, the Composition Builder application can be found in the “Just Playout” folder inside the “Applications” folder of your Mac.
We do not recommend running Composition Builder on a machine where Just Out is installed. Please use a dedicated machine for the realtime graphic template creation.
