Hi Jeremy,
I will take a look tomorrow morning and get back to you… I’m pretty sure that I’m using the AJA KONA DVCPRO 23.98 easy setup but you never know. Thanks for the lead.

Thanks everyone for your help!

The Blackmagic card can also do the HDCAM>DVCPRO encode. But I cannot see live playback during capture, which is unsettling. Also 720p23.98DVCPRO is only 5.6MB/s as opposed to 1080p23.98DVCPRO which is 13.5MB/s. That extra 150% has me worried that I will have enough space in case this director starts to push past 34 hours of footage… he’s a first timer so I don’t want to limit what he can shoot.
update: Ended up getting the Kona3. Now I feel confident I’ll have everything I need to do the job.

Thanks for the help guys!

Thanks Walter… here are my thoughts, let me know if I am off base anywhere:
DVCPRO720p23.98 is ~5.6MB/s while DVCPRO1080p23.98 is ~13.5MB/s. I have a 3TB RAID which formatted in L3 nets me about 2.3TB all in. I am estimating 35 hours of footage putting total storage needs around 1.71TB @ 1080 res. This doesn’t leave me much room for onlining into Uncompressed 10bit 4:2:2 1080p 23.98 (I also, rightly or wrongly, am a little nervous that when the RAID is that full that my read/write data rates may slow enough making ucompressed work difficult…?) I was planning on onlining and printing to tape one reel at a time to save space. We will do color work somewhere else.
If I can capture at 720 the total storage space for 35 hours ends up somewhere around ~800GB, and since I will have to online to uncompressed anyway, why not save that space?
On my Blackmagic system now, 1080 capture, cutting and playback is working fine, but there is no real time preview of footage being captured, which is annoying because you are just sitting there in the dark not knowing what is happening.
Finally is it only the Kona 3 card that can do real time cross-convert to 720 or will the LH/LHe card do this also? (I didn’t mention a specific card because I’m trying to figure out which will work… if I should switch at all… I’m worried about getting it all dialed in in the next day, I haven’t started capturing yet but will have to tomorrow).
Many thanks for your help and guidance!!!!

So the LHe card could not, is that correct Mike?

Maybe I’m doing something wrong, but I have RT on “safe” and Video Quality on “dynamic”. I captured the preset jpeg codec (75%)… it amazes me but truly, it would not get past one cross dissolve on the timeline.
-
Also, it made me a little worried when I have 2.3 TB of storage and it told me in the AV (___) estimation dialogue that I only had roughly 400 minutes of space available.
Just tried the jpeg and on a quad core it couldn’t play back a rendered cross dissolve. Unfortunately this is not going to be robust enough for me.

Thanks Luke… I tried the jpeg earlier and was amazed! The RT Effects thing was kind of a bummer though. Is there any other downside to this codec? Will I have any problems when I want to Online back to uncompressed 10-bit HD?
I found the following post in the FCP forum but am a bit reluctant to try it because it is not supported and if I run into trouble, I want to be able to recover…

Subject: RT Effects for PhotoJPEGI figured out a VERY simple tweak to give you RT effects for the Blackmagic – JPEG Easy Setups.
Without giving away too many details, there’s an RT Enabler txt file somewhere inside the Final Cut application file. Back it up to another folder so you can always restore it later if need be. Now open it up (the real one, not the backup) in TextEdit. Inside there’s a section for OfflineRT (PhotoJPEG) surrounded in astericks. Below this are several self-explainatory lines for max width and max height allowed, which are currently set to 320×240 and such. Change these to 1920 and 1080 (or 720 and 486 – whatever). Change the max spatial quality to 800 or so.
That’s it. It just works. The only prob is that FCP gives you a warning whenever you start up. Just make sure you have “Report Dropped Frames on ETT/PTV” checked.
I can’t stress how great this is. I have a regular gig that requires only simple dissolves. I had been capturing everything at DV and later re-capturing at Uncompressed. Now I can skip the re-capture process and just take the footage in at PhotoJPEG for offline and online.

That one got me to drive all the way back to Westwood. I couldn’t believe that I wouldn’t have tried something that simple. So now I am here and remembering that I went through that step earlier.
The problem with this is that your source must be in that format, not what you want to capture to. The only way I am able to get any video signal recognized in Log and Capture is when the “Capture/Input” drop down matches the incoming video i.e. 1080p23.98 It will capture this in 10-bit, 8-bit, DVCPRO, JPEG… but there appears to be no way to compress the resolution as well.
