aja kona capture edit

anyone have experience editing with the kona capture card? does the portable jvc deck (CU-VH1US-P) work with the kona card? when editing uncompressed, what harddrive configuration is ideal? SCSI, SATA? any advice would be greatly appreciated!

Which Platform? Mac or Windows?

aja kona

Mac platform working with final cut pro. anticipating an easier workflow after the NAB, but the benefits to editing uncompressed seem to alleviate artifacting issues.

I haven't personally used a Kona card with the HD100, but I have used a Decklink HD with multibridge - so in essence the same workflow.
For Uncompressed HD, we have a Xserve RAID with 7 Terabytes, hooked up to a dual 2.3Ghz G5 running FCP5.

The deck would be compatible with Kona if you had the analog component option. You would also be able to control the deck and possibly grab TC through the 9-pin RS-422, but the TC frame rate might not jive with the 59.94 fps of the analog out. I don't have a deck to test, so I'm not sure about the TC.

There would not be a huge quality benefit to capturing uncompressed from tape instead of firewire transcoded to uncompressed, but it would save transcoding time.
The other thing is that the video captured would be 59.94fps, so you would edit in 59.94fps and have to deal with pulldown repeat frames. Cinema Tools cannot currently remove pulldown frames from 720P60.

The huge benefit to uncompressed is to capture live, therefore bypassing the mpeg2 encoded video going to tape. You would also be able to capture 720P60 (while in 720P30 mode) to capture real hi-speed overcranked slow-motion.

Capturing live like this would have to be done in "studio", unless you took along your G5, raid, etc. on location correct? Are there any quality benefits to capturing via DTE, like with JVC's Firestore option vs. tape?

No - its the same HDV digital stream recorded to tape.

Decklink HD with multibridge

Tim,
Do you get any hardware acceleration with
Decklink HD with multibridge?

I have a ton of footage shot in 720 24p
and want to edit in HD without going
overboard with HardDrive Space.
Or should I bite the bullet and get
a 7TB Xserve RAID? rob
