2:3 cadence and ProResHQ
This is an addendum to a thread of a month ago, so I thought I’d pull it forward.
The issue is that 23.98 ProResHQ sequences seem to lock to 2:2:2:4 cadence if you attempt to output the media at 29.97. It also appears to override any Kona output settings, and I certainly get 2:2:2:4 no matter what I set anything to in any dialogue anywhere in FCP… Playback settings, the Kona3 card… nothing changed the result.
Same exact timeline…. baked a new 23.98 ProRes (non-HQ) quicktime and re-embedded it in the original timeline and changed the codec setting to ProRes…voilà, 2:3 cadence and case closed.
Apple…. fix it.

How are you doing this? Via the Kona? So the Kona sends out a 2:2:2:4 signal?
Sorry, I don’t know what you mean. You will have to tell me more to help my crowded brain understand what you are doing and why it is how you say it is.

Yes it sure does. Just to make sure I haven’t obfuscated…
What I have been trying to record to HDCamSR in 1080i29.97 is a 1080P23.98sF ProRes422HQ sequence.Set the FCP AV setting to 1080i29.97 10-bit. Set the System Settings Playback control to 2:3, set the Kona3 to 2:3…. all of these get overridden and what goes out the HD-SDI line is 2:2:2:4 -you can step through the recorded video and that’s what it is. The RT dialog on the sequence only offers 2224 as well.
If I bake a 23.98 ProRes422 (not HQ), even on the same original sequence, the RT dialog suddenly decides that all the cadences are eligible, I simply re-insert to tape and it all works. I don’t have to change a thing, having all the appropriate settings now responding to the call for 2:3.
There is something wrong with HQ — I have also had the instance occur where a 1440×1080 ProRes422HQ sequence was interpreted as DVCPro50 whenever picture was passed over to the Kona3 card by Edit-to-tape or even in the KonaTV utility.

Ahhh….now I see.
But why set the AV settings to 29.97? You aren’t supposed to do that I don’t think. No, you set FCP to match your sequence and footage…23.98. Then in the Kona CP you make sure that THERE is where it converts things to 29.97.
Unless I am mistaken. I need backup from Walter and Gary and Jeremy on this. And Jerry…

My Kona3 doesn’t support simultaneous frame rates in HD… If I set the FCP AV out to 23.98, of course this overrides the Kona and the A output is 23.98. I cannot set the B output to 29.97 unless its SD… kinda defeats the purpose.
