I do have it set to remove duplicate frames – but I just noticed the stuff shot at

format 720p24 with 2:3 pulldown and some a “shooting rate” of 4

imports as 720p60 with duplicate frames in the 2:3 pattern – and real time, not time lapse or slo-mo. Weird… I would have thought that should have yielded a 24fr QT.

I’m reasonably sure that my camera op (not a pro) had no clue what he was doing – but I’m trying to figure out what he did wrong in order to tell him how to do it right.

(and I’m also trying to edit with the least amount of render time…)

Jeremy – I understand how 720p60 Varicam works in theory. What I am saying is that the shots play back in real time – without any time compression or expansion.

A shot that lists its’ format as 720p60, and it’s “shooting rate” of 6 – that shot, when converted to a quicktime -plays 60 unique progressive frames in NORMAL time – there are no duplicated frames. If it was shot at 6 fps – the quicktime would either have 10 repeated frames if it kept the extra frames, or it would play at 10 times normal speed if it removed the extra frames, right? Neither one happens. The shot actually plays 60fps in normal time.

For example – look at my IMPORT P2 screen from here:

https://homepage.mac.com/jahns/P2_Import.png

Look at: Shot Name 000747 – 720p60 – Shooting Rate 6

here’s a low res version of the QT file: (11MB)

https://homepage.mac.com/jahns/000747.mov

as you’ll see, the action is in real-time at 60fps. Why would that have a shooting rate of 6?

Hmm… yes, that works – but it seems wrong to have my video output set to 1080i29.97 when I’m working at 1080sf23.98. I know I’ve done this before, and I don’t recall having to futz with the settings like that. I guess FCP is then feeding it the 2:3 pulldown?

I wonder if the previous Easy Setups for 1080sf23.98 used Vid Playback at 1080i?

Thanks for your help Jeremy.

Thanks for your help Jeremy. (I’m having all sorts of problems today, eh??)

I guess I’m not explaining myself well. None of the footage I am referring to was shot with any variable speed frame rates. It all plays in real-time, regardless of what the “Shooting Rate” column says – the 720p24 plays 60fps with 2:3 duplicated frames – and the 720p60 stuff plays 59.94 progressive frames.

Here’s a screen grab of my import screen:

https://homepage.mac.com/jahns/P2_Import.png

The highlighted clip (with shooting rate 30) plays 60 frames in realtime, but gets imported as 29.97 with jumps in time ever few frames – all of the other clips import fine and play as expected. And P2 Log Pro can create the QT file properly from this same clip, so I’ve found a workaround, I’m just trying to determine what the heck is going on, and how to avoid this problem in the future.

I’ve posted the FCP imported version at:

https://homepage.mac.com/jahns/0010GY-30.mov

If you step through it frame by frame, you notice jumps in time – it was definitely shot at 60fps – so why does “Shooting rate” say 30 – or any of those other rates when it was NOT shot variable?

thanks for your help Jeremy.

The problem is that my 525i is grayed out in secondary format. See screenshot:

https://homepage.mac.com/jahns/1080-24_2_NTSC.png

525i is OK if I’m at 1080i, but as soon as I change Primary to 1080sf23.98, the only secondary format that isn’t grayed out is 1080sf23.98.

I know I have done this before without any problems, but now AJA is telling me that the KONA 3 can do that, but not the LHe – which is b.s.

Any suggestions?

But all of those clips were shot at 720p59.94 – not 7 or 42 frames per second – most of them play just fine as 60fp shots – except the ones that had 30 in the “shooting rate” column. It’s like that “shooting rate” column assigned random numbers or something.

I wish I could post screenshots to illustrate – maybe no one else has had this problem?

Yes – I will edit at 720p24 – and run all of the 1080 footage thru compressor to downconvert – which looks much better than FCP’s Batch Export downconvert. Thanks!

Thanks, guys – good to know that SHOULD work and I’m not crazy. I’ve been using the LHe for over a year – and I know the control panel interface. I have tried the normal methods of doing this. The problem is that when I try to choose 525i – it is grayed out.

When I choose Primary 1080i29.97 – I can downconvert just fine. When I switch back to 23.98 – my secondary format of 525i turns gray (red on the SDI Output graphic).

AJA Support just wrote me back that “The KLHe can’t do the cross convert, the K3 will do 1080sf 23.98 to 525i29.97.”

That is flat-out wrong – I’ve done this in the past – and both you guys have confirmed it, right?
