Add background

We will now project independent content on the background using the same projector.
First, increase the pixel workspace from 1920×1080 to 3840×1080 (2 HD) in the General tab.
Then go to the Output tab and add an XMAP just after the general warp, it will then be in the cube’s background: set the map (the extraction area) in top left to 1920.0 to capture the area starting from 1920 pixels. Switch this XMAP to keystone mode.
Go to the Playlist tab: rename Playlist 1 and add a second Playlist.
Select the second Playlist and add 3 cues.
Drag&drop a background media on cue 2.
Set the media position to 1920.0. (This corresponds to the area extracted from the background).
Then use the copy/paste function to duplicate cue 2 several times, then replace the media in the new cues with another background media.
Go to cue 2 and then back to the Output tab > in the Shape sub-tab. Select the XMAP background and warp it to the back of the mapping box.

!In this exercise, we chose to create two independent Playlists: one for the cube and one for the background because we have media without any link between the background and the cubes that we want to play independently. If the media had consistency when being played together on the cube and the background, we could have used a single Playlist with several cues, each cue with the background media on layer 1 and the cube media on layer 2.
