  Capture offset question for new set up

  Posted by Dan Riley on October 2, 2007 at 9:17 pm

  I’m capturing a DigiBeta A500. If I set the capture control preset to
  AJA Kona3: 29.97 Sony VTR B, it says the capture offset is -1.5.
  Minus 1.5 ??? Is this correct? It offsets a half a frame? A field if you will?
  And the playback offset is set to +00:00;01
  I did not set any of these. This is what came up after the installation.

  If I select:
  AJA Kona3: 29.95 Sony VTR A, it still has a capture offset of -1.5 frames
  but the playback offset is 0. Which Sony machines use the A VTR?

  To capture from our Panasonic AJ 455 I use the Panny seting which says
  it uses a -2.5 frame capture offset and no playback offset.

  This seems totally random to me. How does the AJA card know
  which Panny deck I’m using, or do all of them need 2.5 frames offset?
  With the AVID there is a setting for every type of VTR ever made it seems,
  but these setting look more generic.

  The reason I’m concerned is we will be doing offline/online stuff with tapes
  captured from other places, some from firewire, some from an AVID sequence
  that is translated via The DUCK, then recaptured from a batch list.
  If my settings are delaying the video relative to the timecode numbers
  this could be serious.

  What are the settings you guys are using for your decks?

  Thanks,
  Dan
