4:2:2 color

[Mike Velte]

Digital Video captured via firewire is 4:1:1

With an expensive analog capture card like Deck Link, and its associated plug-in for Pro, you could capture analog from a Beta deck/cam via SDI in 4:2:2 color space, but any effects applied will cause Pro to render in 4:1:1.

[Peter Corbett]

I beg to differ Mike. If you use the Decklink 8-bit or 10-bit project presets within PPro, rendering will not be 4:1:1. Rendering stays at 8-bit 4:2:2 in the current version of PPro and isn’t downsampled to 4:1:1 or 4:2:0 for PAL users.

Just to be clear that firewire is not limited to DV 25 Mbps 4:1:1.

AJA IO (for FCP) does uncompressed 4:2:2 video over firewire. I believe at least one of the Panasonic decks will do 4:2:2 DV50 over firewire.

Convergent Design has a box that WILL soon reportedly do uncompressed 4:2:2 over firewire. Compatible with Premiere.

I believe they were demonstrating uncom firewire into Premiere at NAB.

Convergent Design was in fact demonstrating the uncompressed over firewire capture and playback at NAB with Premiere. We are developing the tape deck control now. If you would like to beta test the new drivers, send an email to sales at convergent-design.com. I expect a set of fairly polished drivers available in May.

If you wanted to (and had the horsepower) you could capture 10-bit, uncompressed, 4:4:4 color video and edit it in Pro. Even HD. The limits are related to how you bring the video in and how you render it out.

Thanks John,

I’ll have to wait a bit as my DVCPRO50 VTR only has SDI out, The new decks have firewire, but uncompressed firewire is probably not on my particular wishlist. (unless there is an application I haven’t considered)

Cheers,
Peter

Hi Peter,
You could take the SDI out from your deck into the SD-Connect and transport this video uncompressed to Premiere and vice versa.
Does your deck have RS-422 control? The SD-Connect can take commands from Premiere and convert them to RS-422 commands for your deck.
If you would like, we offer a 15 day free evaluation.

Thanks John for the offer,

I already have a SD-Connect! Because I have a Decklink card I don’t know if there is an advantage for me to go in to PPro with firewire uncompressed. (or is there?)

Hi Peter,
Oops!
There would be no advantage to use the SD-Connect in your case. I assume you use it for analog to SDI conversions? Have you seen the new RS-422 loop thru control? Also, we just added 422 to 1394 control.
