For sound: SMPTE buzz track and Dolby pink noise (cat. 69P) at minimum for a mono system. Add Dolby Tone (cat. 69T), left/right (cat. 97), and possibly illumination uniformity (cat. 566) for an analog Dolby system. You will also want a test reel of a film that you know well to verify the quality of the sound alignment. The sound alignment procedure is explained quite well in the Dolby manuals , and the principles are also applicable to other makes and models of processors.  |  IP: Logged Victor Garcia Film Handler Posts: 13 From: Mexico city, Mexico Registered: Aug 2012 posted 01-23-2013 04:56 PM                     thanks!  |  IP: Logged
