PAL capture / NTSC deck control
I am capturing in FCP, Composite PAL uncompressed 8-bit from an NTSC to PAL converter, playing back from an NTSC Digibeta machine with a tape that has non-drop timecode, patched composite into the converter. I am doing this successfully with the AJA io deck control set to non-controllable device and just manually pressing play on the deck and patching PAL black burst into the AJA io. I did a test changing the deck control to RS-422 NTSC and the PAL capture seemed to be fine. I would love to be able to Batch Capture with deck control from my NTSC Digibeta. Will my clip eventually be out of sync somehow with my 25 fps sequence if I capture with RS-422 NTSC control? Does the RS-422 NTSC control non-drop timecode get captured with the PAL signal, or is non-drop code, non-drop code no matter what the frame rate the clip is?

Drop or non drop won’t make any difference. PAL has 25 fps and NTSC 30 fps (sort of. You poor buggers know the agony of 29.97)
So as soon as you use deck control, the capture should abort when the timecode fails to click over from 24 to 00. Also timecode is meant to be syncronous to the actual frame which won’t happen if you control the NTSC deck. You could tell it not to make new clips on t/c breaks. This will create clips with useless code but might let you have machine control to trigger capture now.

Thanks Michael, that’s what I thought. Although I was holding out a little hope.
