    Time Code (702T only) The 702T uses time code circuitry developed by Ambient Recording GmbH, a leading developer of stable, portable time code products (visit Ambient on the web at www.ambient.de). Clock stability and continuity are critical aspects of the 702T time code implementation.

  • Page 29: Frame Rate

    All fi les generated by the 702T have time code numbers begin on the :00 frame (or 02 in DF modes). If necessary, pre-roll is dynamically applied to accomplish this. This simplifi es synchronization in post-pro- duction.
