You should be able to shoot 1080 24pA on the HVX, then remove the pulldown and then use a FCP 1080 23.98 timeline. Let me know if you have any trouble with this – I haven’t used this workflow before, but it should work!

Any particular reason you have to shoot 1080 24p? FWIW, the 720pN 24 frame mode produces images that are nearly indistinguishable from the higher-res versions, and at a bandwidth that’s closer to DV. And it drops right into an FCP timeline, quick and easy, no pulldown necessary.

Actually, they’re not. I tried the answers suggested above and wasn’t able to fix the problem, hence my post.

I’m having the same problem with SnapZ Quicktimes. I opened the clip in Cinema Tools, but the conform option was greyed out.
Compressor seems to work, but this seems like a ridiculous workaround. Does anyone have an idea as to why this happens? Were you using a registered version of SnapZ or the Trial?

UPDATE:
I just got off the phone with AJA support… Apparently the Kona LHe card will downconvert on output, NOT on input. I was told the card will take a 1080 signal down to 525 after the framebuffer, but not before. So, problem solved apparently.
Thanks,

[Arnie] “There are 2 versions of the Kona driver. The “NDD” version (No Digital Desktop) does not have any desktop display. The other version will. If you’re a Shake user, you don’t want the NDD version.”
According to the manual included in the 6.0.3 .zip, the regular version should allow you the checkbox option to switch between desktop display enabled or disabled. Is that not the case anymore — that you have to choose prior to installation if you want NDD or not?

“That has worked since day one, as Gary notes, it was 23.98 that was fixed.
In FCP you should be set for HD.
In the AJA Control Panel you should have your formats set correctly and the output set to 525.”Walt,
According to Kona’s own support personnel, the 1080i 29.97 to 525i 29.97 downconvert didn’t work properly with the 6.0.2 release. Their release notes for 6.0.3 states that this was fixed:
“Resolved an issue during capture involving down-conversion of 1080i29.97 to 525i29.97.”I, however, have not gotten this fix to work.
I’m not setting FCP to capture HD because I don’t want the files in HD — I’m using them in SD, hence the need for the downconversion prior to capture.
Everything is setup properly (FCP: 525 capture, Kona Control Panel: 1080 in, 525 framebuffer, downconvert between the two) but for some reason it’s not working properly — I’m getting stuck frames instead of smooth video.

“My copy of the notes say that it is 1080sf 23.98 to 525 29.97i is what is fixed.
And downconversions need to be set in the Kona Control panel, not from within FCP.”Gary,
According to Kona’s release notes:
Resolved an issue during capture involving down-conversion of 1080i29.97 to 525i29.97.As for the downconversions — I am setting it up properly in the Kona Control Panel. I want to capture 525 in FCP from a 1080 source. So in FCP, I set the capture template properly – to 525. Then in the KCP, I have the source at 1080, frame buffer at 525 and output at 525. The Downconvert icon shows as it should between the input and framebuffer. But I’m only seeing frame stutter in FCP and my output monitor. When I try capturing 1080 and then downconverting to the 525 monitor, it works fine. I’m guessing the fix Kona issued (as referenced above) for some reason isn’t working my system yet.
Any suggestions?
Thanks,

Jeremy,
There’s no copy protection, as the card captures the 1080i fine — it’s the downconvert it struggles with.
I got a customer service response from AJA — apparently there’s a bug in the 6.0.2 driver that should be fixed with an upcoming 6.0.3 update. Until then, they recommend going back to 6.0.1. I’m hoping that switch will make everything work as it should.
Thanks for your reply,
Marc

I’m not sure I follow you. The file was progressive — 23.976 full progressive frames, no interlacing, no pulldown whatsoever…
