You can start a stereoscopic
            session in Action by loading stereo clips and using the Stereo Startup
            mode. This creates a stereo camera. The output is set to the stereo
            camera, a stereo object is created for visualizing the scene, and
            the clips are placed on separate lines in the Media list.
         
         NoteA stereo clip cannot
               be loaded in Action if it is selected as the Back or Multitrack
               input, or if it is selected to replace a clip in the Media list.
            
         When using a stereo clip,
            its left and right eye tracks are automatically split and placed
            on individual lines in the Media list. Also, new clips appear on
            the Desktop. They retain the name of the original clips, and
            are appended with a “_Left” or “_Right” suffix. It is important
            to save these clips in the library, as they are used for loading
            an Action setup or loading the previous Action session.
         
         NoteIt is not possible
               to select a mono clip as the Matte input if the Front input is stereo,
               and vice versa.
            
         To start a stereo session:
         
         
            - From the Main menu, click Effects, then
                  Action.
- From the Input Mode box, select one of
               the following:
               
                  - Clear All to delete all media and objects
                     from the previous setup. Select stereo clips for the front and matte
                     input. This is the Stereo Startup mode.
                  
- Front/Back/Matte to enter Action using
                     the previous setup. Select stereo clips for the Front and Matte
                     input, and a mono clip for the Back input.
                  
 NoteIf you enter the
                     Action module using mono clips, the default camera is automatically
                     created. If you need a stereo camera, you must add it manually.
                   
- Select the destination.
               If you selected Clear
                  All and selected stereo clips for the Front and Matte input before
                  entering Action (Stereo Startup mode), the following is created:
                
                  - In the schematic, an FBX camera (stereo
                     camera) is created and the default camera is hidden.
                  
- In the Output menu, the Mode is set to
                     Stereo and the Camera is set to Result Cam.
                  
- In the Camera menu, the result camera
                     is set to the FBX stereo camera.
                  
- A stereo object is created with the clips
                     you selected.
                  
- In the Media list, the Front and Matte
                     inputs are split into separate lines for the right and left eye.
                  
 NoteIf you entered Action
                     using the Front/Back/Matte option and want to clear all previous
                     settings and use the Stereo Startup mode, click the Stereo Startup
                     button in the Action Setup menu. You will now have to bring in new
                     clips.
                   
When you exit Action,
                  the Desktop contains left and right clips for the Front and Matte
                  inputs for a total of four new clips.
