DVCPRO System Timing Considerations
The DVCPRO codecs used in Profile systems are actually pairs of codecs. Because of this
paired codec architecture, some restrictions apply to the DVCPRO codecs which require the
following system timing limitations:
1. You must supply a Reference In signal to the Profile system.
2. All video signals that you want to record with a DVCPRO codec must be synchronous with
the Reference In signal.
3. If you want to use the DVCPRO codecs as independent codecs, all of your video inputs
must be auto-timed to the Reference input. In Configuration Manager, select Enable
Auto-Timing for each input. You must ensure that each input actually auto-times by
checking that the Auto-Timed indicator in the Video Input dialog box is lit. Refer to “Using
the Profile Configuration Manager” in the Profile Family User Manual for more
information on Auto-Timing.
4. If you are unable to auto-time an input, or if you wish to use the DVCPRO 25 codecs for
BVW Insert/Edit operations, you may only use one of the codecs from each pair,
DVCPRO25 #1, DVCPRO25 #3, and DVCPRO25 #5. Note that the second DVCPRO 25
codec from each pair must not be used.
