# Selecting a Raster for Playout

When playing out to an external device, you must select a raster. See Supported Video SDI and GFX SDI Rasters.

NoteWhen you select a drop frame (DF) video format, the timecodes are calculated in Drop Frame mode.

To select a raster for playout:

1. In the Video Device SDI group, toggle the Video/Graphics raster option box to display your video card (AVIO). See Playout Menu Options.
2. Select an option from the Link Type box. Select Single for a 4:2:2 video signal, and Dual for a 4:4:4 video signal.
3. Toggle the Format option box to the required raster format (SD, HD, Film, or Audio).
4. In the Raster list, select the raster for playout.
   NoteIf clicking on a raster in the Raster list does not select the item, that format is not available for capture on that system.
5. (Optional) If you need to add 3:2 pulldown frames when playing out, enable Pulldown.

   The pulldown is added to the played out video. The first frame played out becomes the AA frame in the pulldown sequence. See About 3:2 Pulldown.
