Recording uncompressed to HDD
Hi everyone,
I’m before a long shooting of pure green screen footage, and since keying will take quite long, we try to spare some time wherever we can. So I had the idea that instead of recording to digibeta, then renting the deck and capturing 5 days continously, we should try to record straight to hard disk, if we can. We have decklink cards and a external raid storage. What’s missing is the software. OnLocation seems only support firewire things, but we using SDI, uncompressed instead of DV. Could premiere be a solution ? What other solutions exist out there ?
Thanks for everyone for any help one could offer ! -

Does Black Magic have a capture application like AJA has Machina?
…I’d still roll DigiBeta as a backup.

I 2nd Tim’s suggestion of tape as backup.
DeckLink has their “decklink” app which will grab and play back single clips. It probably got installed somewhere on your machine. It’s not elegant, but should suffice.
I would guess you could do it via Premiere’s Capture window as well (just press “record”?), but have not tried it.-jeff

it looks rather plain, indeed. i would rather use premiere then, since they seem equally crowbar-like, and premiere at least look alright.
Thanks for the advice ! -
Is it possible to record straight to DVCPro50 avi ?
-
I’m not a Black Magic user myself, but I was under the impression that they had their own 4:2:2 compressed-for-production-use codec.
I would suspect that a Mac might capture/compress to DVC Pro50 on the fly, but I’m not aware of anything that captures uncompressed and converts to DVCP50 on the PC side (though that doesn’t mean that something doesn’t exist of course…)

I have on the odd occasion taken a box out with PPro and a decklink card to an outside broadcast where I capture live and edit then turn it around and play it back out to air with no problems. Just remember to have a fast array for the uncompressed SDI stream.
Blackmagic do have a compressed format (MotionJPEG) which is very good but I would test it first to ensure it doesn’t create artifacting on your chromakeys.Just as an FYI I recently was involved in a hi-def OB where I did the same turnaround capture/edit with PPro – you gotta have good nerves when doing that type of work, especially when you are relying on Adobe software to perform!
