dvcproHD to HDCAM (FCP)

Hi Everyone,

I've seen this coming through our facility a couple of times and would like to see what you think is the best workflow for DVCPRO HD to HDCAM using Kona gear running under FCP.

Th equipment that I have at our facility, a mac w/Kona3 and FCP, a mac w/Kona2 and FCP, the HDCAM-SR 5500 deck and a SONY HD CRT monitor.

Typical workflow, clients shoot on p2 media at 720p 23.98 and as I understand it really is just 23.98 packed into a 720 60i signal w/redundant frames. When I play this out using KonaTV, the signal is in fact a 720 60i signal.

The HDCAM-SR deck can record HDCAM, but only at 1080psf23.98 and 1080i60.

So, either I can take the 720p dvcprohd file and upres it to 1080psd23.98 using final cut (it will play out without rendering "orange") or have the kona3 card convert that to 108060i on the output.

Is this the correct to do this or does someone else have any suggestions?

Thanks Jose

If they shot 720p 24...yes. But if they shot 720p 24PN, then they should have 2f actual frames per second. What did they shoot? What are the clip settings and what is the sequence setting?

Use the Kona 3 to CROSS convert 720p to 1080p or 1080i...or whatever their requirement is...on the fly as they export. That is an option on the Kona 3. And is something that I have done regularly.

The file specs in Quicktime... DVCPRO HD 720p60 fps 23.98

I brought up a 720p23.98 timeline and with the Kona3 control panel I am able to crossconvert on the fly with no rendering. Thanks!

DVCProHD 720p60 is the name of the codec. The frame rate is 23.98. The fact that a frame rate is included as part of the codec name is a source of confusion for many. The same problem exists with a number of other codecs. For instance, if you use the Kona 1080 Uncompressed codecs, the codec name will be 1080i, even if you are recording progressive. This is also true with DVCPro, which leads many to believe that you can't have 1080p/23.98 DVCProHD files (because the codec itself is called DVCProHD 1080i).

Quick Update - 03.21.08

I was able to take dvcproHD 720p60 footage @ 23.98 and bring it into a FCP dvcproHD 720p23.98 sequence and have it upconvert to 1080psf23.98 using a Kona3 and lay that back on to the Sony HDCAM-SR 5500 deck. Problem is, the combination of settings/drivers in FCP causes inconsistent frame delays on the tape. So sometimes the show lands dead on or sometimes early or late a frame or two. I was finally able to lay it off correctly after 2 or 3 attempts.

Has anyone had this issue working with dvcproHD media going to HDCAM-SR?

Here are my settings:

FCP:

footage- 1 hour DVCPRO-HD 720p60 fps 23.98
easy setup - AJA KONA 3 - 720p59.94 DVCPRO HD
machine control - 23.98 SONY VTR A, is this the right setting?
(defaults to panasonic, I added 8 channels of audio to this preset)

KONA CONTROL PANEL:
format - native, 720p23.98
secondary, 1080sf23.98

digital out - both secondary

ANY help or insight into this is much appreaciated.

Yeah, we do have that issue. But my layoff guy has a trick that he uses to tell if we are off so that we don't have to layoff the whole 44 to 90 min show before we find this out. He won't share this trick with me though...calls it "job security."

Darn him.
