Hi Peter,

when using sync to smtpe or sync to midi the inframe and outframe values act a little different comapred to other playback modes.
they act as an offset to the incomming timecode - so you can compensate for any delay that may occur on your signal chain...
The good thing abou an offset is that you can still adjust it while it is playing back.
I keep forgetting it but I believe that the inframe is the positive offset (i.e. Inframe = 1 Timecode 0:0:0.0 results in playback of frame 1 / Inframe =25 Timecode 0:0:0.0 > Frame 25

The Outframe is the negative offset.

Catalyst will only read minutes second and frames of the timecode and ignore the hour value (max offset can be 43.7 minutes...)

Hope this is a little help...
