Logging Preroll
Be sure to leave adequate preroll with continuous timecode before IN points when logging your tapes. The recommended minimum preroll is 2 or 3 seconds for Betacam playback, 5 seconds for 3/4-inch U-matic playback, and 6 seconds for DV playback.
  Use Deck Settings (click Add Deck in the Deck Configuration dialog box) to set the default preroll for tape playback.
