Digitize to DVC Pro HD?
So I have a duel link 444 card and would like to offline my HDCAM-SR to DVC Pro 23.98 in either 1080p or 720p.
A few months ago with the older driver I couldn’t do this, but can someone tell be definitively if I can do this?
If anybody has any gotchas with using this as on offline method for a feature, please let me know.
Thanks so much.

Some time ago we digitized HDCAM via SDI to the DVCProHD codec using a Decklink HD card. The driver was 4.7 on a Mac G5. We just did it for a test, and it worked fine. The results were interesting. On individual, side by side frames with the same media captured as 8-bit uncompressed HD, the results were quite close. When in motion, however, it was easy to spot the DVCProHD conversion, though it was still quite impressive.
This, of course, is just a passing comparison, since the idea of converting HDCAM to DVCProHD on-the-fly is a little weird.
I suppose for your use, this would do quite nicely.

Erik,
Take a 4:2:2 single link HD-SDI feed from your HDCAM-SR deck and it will work, use the Blackmagic HDTV 1080psf 23.98 – DVCPRO HD easy setup if shot progressive and the straight non psf seup if shot interlaced (unlikely).
As ever test the production process end to end and do a test edit, do a little edit using footage from a a couple of tapes in the DVCPRO-HD offline, using media manager make an “offline” using Blackmagic HDTV 1080psf 23.98 – 10bit RGB 4:4:4, connect to the HDCAM-SR in 4:4:4 dual link, batch capture the footage in at full quality and confirm everything works as you expect.
As you are using media manager, it freaks with time remapping so do fancy stuff online. Do a search for media manger in the FCP forum and over at LAFCPUG.
I do a lot of HD used as offline/digital rushes for 35mm features and know you are going to have an interesting dilemma about upgrading to FCP5 in the coming weeks, tough call as some of new features are great for offline feature work like audio control surface, dynamic RT and multiclip etc.

Thanks so much for the responses. Any wacky speed changes will be done outside of Final Cut and brought back in.
