Great news, Jeremy!
Thanks to your efforts, I tried again.My main mistake was to change the framerate to 50 in device control. When set to 25 and 1 frame playback offset the resulting file was down to one field offset. So I switched back to let the IOhd do the conversion and set playback offset to 2. After that it was spot on.
Thanks again for your patience and help.
Best regards,

Hello Gabriele,
in your specific situation it might be best, if you rent a kipro to test your workflow.

Hi Gabriele,
yes, the kipro acts like a deck and receives timecode via 422.
The recording duration depends on your chosen flavour of prores and the size of the hdd.
I’m not quite sure what happens on a timecode break during edit to tape, but theoretically you could work without deckcontrol and have the kipro start and stop recording whenever timecode is coming in. The parameter is called “arm recording” and can be set to tc. Then it should create a new clip whenever timecode is coming in. There might be a slight delay of a few frames before recording sets in.
I don’t know if this workflow is applicable to your situation, though.Greetz,

Oh, it’s a very simple timeline. It consists of just one 30 second long clip. It’s only purpose is to test this workflow.
I unchecked everything in the mastering tab of the ETT-window, because what I really want is just a downconverted file that mirrors my timeline so that further processing can take place. (e.g. sending to compressor and combining with different audiomixes)
No spaces or anything in the timeline.Torben

As soon as I realized there are duplicate frames at the beginnig, I superimposed some numbers at the start of the timeline to keep track of what is going on.
I renamed the copied device control preset to “KiPro”, so I can check in the ETT-dialog that I chose the correct one. Though I’m not quite sure if you have to restart final cut to make any changes come alive.
All drivers and software are up to date.
Today I tested a different setup: MacPro with internal Blackmagic Decklink HD Extreme connected to the KiPro.
Same result. 3 duplicate frames at the beginnig of the resulting file.
So it has to be a wrong setting in final cut or the kipro that is causing this behaviour.Torben

No luck, yet. The same duplicate frames show up when I let the KiPro do the conversion. I also played around with the “playback offset” parameter in the device control settings, but it is also ignored by the KiPro.
Thanks again for taking the time to set up your gear for recreating my problem. Much appreciated.

Hi Jeremy,
the IoHD handles the downconversion. I was under the impression that the two devices share the same scaling algorithms. Do you think there is a difference?

Thank you for the suggestion.
I’m afraid the next test has to wait until next week, but I will post my findings as soon as possible.
Have a nice weekend.

UPDATE:
Upon closer inspection of the recorded file, I noticed that the first 4 frames are duplicates of the first frame of my timeline. So the process isn’t really frame accurate. I tried to compensate with the “capture offset” setting, but this value is ignored by the KiPro.
Anybody experienced the same behaviour?Torben

Yes, I did perform an “edit to tape”.
Here is how I got it working:
I followed your advice and used the easy setup “AJA IoHD-720p50 Prores”.
Then I copied the “AJA IoHD:25 Panasonic VTR” device control setting.I edited this setting and changed the framerate to 50. I also removed all the offsets and set the pre/post roll to 1 second.
In the “edit to tape” window I set the In-Point to 01:00:00:00 (the same as my timeline) and performed an assemble edit.
The KiPro takes a few moments to react, but then it starts recording after the 1 second preroll.
It works like a charme.Thanks for the quick reply Jeremy.
Have a nice day.
