You have the possibility to link those formats. How can you do that? Well it's really simple: let’s assume that you want to stop the 3D version of a film and continue playing the 2D one. The link is done by selecting from the "Playing" list the 3D version title and in the "Film Settings" tab, next to "Link show" you have to select the 2D version from the drop-down.
The admissions and forecasted admissions for the 3D version will be transferred to the 2D one and they will be taken into account when scheduling the 2D.
After linking the two versions, a Correction factor appear, which is used to denote how similar the two linked versions are. By default, the value is 0%, which means that the two versions are 100% similar. If needed, you can of course adjust the value.
To un-link two versions, select the version stopped (3D in our example above), and select None in the drop-down menu of the Link show to option.
