For the ISDN setup I’ve used a combination of 4 settings: Layer 3 (I think we did a Layer 2 session once) Stereo or Dual Mono at 48k or 32k sample rate. I basically setup according to the receiving (chasing) studio. When I asked why a 32k sample rate they said they’d had better luck with the tc. But I’ve used 48k with some studios and never had any trouble. I’ve never been the chaser, only the chasee. We almost chased a couple of weeks ago for the new Barry Levinson film, “You Don’t know Jack,” but the schedule changed at the last minute.
As for setting up the Sync IO:
In Setup Menu > Session:
Clock Source – Sync IO
Time Code Rate – specified – usually we get a 29.97 QT of picture
Sync Setup to Generate tc External t/c offsets 0
Clock Ref – Video Ref
Positional Ref – Generate
Video Format – NTSC
Time Code Settings
Generator – CHECK “Using SYNC”
Freewheel – NONE
Pull Up/Down – None or as specified
Sync Setup to Chase tc External t/c offsets 0
Clock Ref – Video Ref
Positional Ref – LTC
Video Format – NTSC
Time Code Settings
Generator – UNCHECK “Using SYNC”
Freewheel – the number frames of bad t/c tolerated before stopping – 8 is default, higher as necessary
Pull Up/Down – None or as specified
That’s pretty much it. Make sure the Transport is Online. I always forget. Also, I always insist on a test hookup with picyure before the actual session with studios I’ve not worked with before.
