January 19, 2006 at 2:46 am in reply to: 4:1:1 DV offline to 4:2:2 output for Broadcast.You’re right, I’m not adding anything to the existing colour. There is no more info than what’s on the original tape. But I am now colour-correcting and working in an uncompressed colour space which looks much better than DV.
The only thing I’m adding is the all-important “u” in the word colour 🙂

January 18, 2006 at 11:47 pm in reply to: 4:1:1 DV offline to 4:2:2 output for Broadcast.Let me throw in my workflow. I deal with a lot of clients who offline their shows in DV. They media manage the finished show to a firewire drive and bring it to me. I load up the project and duplicate their finished sequence, changing the sequence settings to Uncompressed 10 bit. (I have a Blackmagic card in my on-line system)
If the material is interlaced, I move it down one line in the motion tab to align the fields correctly. (This is because of the difference between DV 480 frame height and uncompressed 486 frame height) I then colour correct the shows and add the chroma resample filter included in the free Too Much Too Soon filter set (But make a donation, it’s a great filter set). Then I output via SDI to Digital betacam.
I haven’t seen a better workflow for material that originated on DV. Some people say you can get slightly better images capturing from a DV deck with SDI output, but in tests I’ve done, I haven’t seen a difference. The chroma resample filter takes care of DV vertical chroma banding in dark intense colours like red. I’ve deliverd hours of material to broadcasters using this workflow without any complaints

Hi Sean
As a former Cinewave owner, I feel your pain. Keep in mind the Multibridge Studio isn’t shipping yet, but I spent a lot of time at the Blackmagic booth at NAB. The Multibridge Studio is designed around PCI Express, The card that goes in the computer is a very simple interface card, all the video processing happens in the MB itself. They mentioned 2 lengths of cable that could be used between the interface card and the MB, and I think the longest one was over 3 meters (but don’t quote me on that) Grant Petty was saying that the cable has to be spec’d very carefully and there is a limit on the length. Blackmagic spoke as well about an interface card for existing Powermac owners that will convert PCI-X to PCI-express although you won’t have the speed of PCI Express.If I were you, I’d hang on until the Multibridge and the new quad-processors Powermacs ship. The combination of the two is going to be very powerful.

How does the Dell look vs using an HDLink and the Dell. I assume your connecting the Dell via component?
[Matt Dowling] “But if you want to monitor in true 1080/24p, HDLink and or a Dell 24″ LCD is the way to go. We all use the Dell 24″ in house – fantastic monitors and great value for money.”
