You can apply a letterbox overlay on output. The letterbox does not affect the clip itself; it is applied on the fly as part of the real time output process.

To output clips with a letterbox overlay:

1. In the Output Clip menu, click the Deliverables tab to see the Letterbox controls.

   
   

   (a) Letterbox Offset field  (b) Letterbox aspect ratio field  (c) Colour selector box

2. Enable Letterbox.
3. Set the letterbox options:
   • In the Aspect Ratio field, enter a value to set the aspect ratio of the letterbox overlay. Alternatively, select a preset from the Aspect Ratio box.
   • In the Letterbox Offset field, enter a value to shift the letterbox overlay up or down, as required.
   • Use the Colour Selector box to set the colour of the letterbox overlay.
