Premiere Pro DV25 to 10bitUncompressed conversion via firewire.
Hi folks.
I’m about to buy a PC system with this new Decklink Extreme PCIe card.
My main workflow would be:
-Digitize to Premiere Pro from a dv tape via firewire(the material was shot in DV)
-Color correct the video material in a 10bit Uncompressed Timeline
-Tiff or cineon sequence(tranfer-to-film).I just read in this forum that this workflow (dv-to-10bit timeline) it’s not the right process to get the best quality, that I can have some loss on these conversion, especially on reds(for best results i should reconform all the material via SDI).
On FCP the workaround for this issue would be apply a 4:1:1 chroma smoothing filter.
What about Premiere Pro? What should I do to get the best result?
I dont have money to buy a DV deck with SDI output…and the reconform process takes too much time..Thanks in advance.

Keep in mind that you don’t necessarilly want to compare this to the FCP method. With FCP, the need for the Chroma Smoothing filter is due to the fact that the Apple DV decoder doesn’t do this automatically. For all we know, the Premiere DV decoder (made by MainConcept I believe) could work differently.

Thanks for your reply!
“For all we know, the Premiere DV decoder (made by MainConcept I believe) could work differently.”
-so the premiere encoder differently better or worst?
(sorry but i still confused, and that’s a very important issue for a finish process)thanks again

DV to 10bit uncompressed.
I would try to take a component or SDI feed from your DV material. If that is not possible use the firewire interface and capture to the uncompressed timeline in Premiere.
Once you have captured the final media export from Premiere Pro and use framelink to generate the DPX sequence.

thanks Andrew.
So, do I have some loss capturing via firewire ?
My image gets better capturing via SDI or Component?
Sorry man, I didn’t get…It should be the same..the both ways, shouldn’t?I only have firewire decks…
thanks again

[bernardo] “-so the premiere encoder differently better or worst?”
Decoder, not encoder ;). I have no idea if it’s better or worse. I would check the Premiere Pro forums, or I would send an email over to MainConcept. Regardless, if you capture SDI, you won’t have to worry about it, albiet it’s a huge waste of drive space.

Going out SDI or Component Analog and then digitizing uncompressed causes the hardware in the deck to decode the DV-encoded footage, and up-rez it to the 4:2:2 10-bit color-space of base-band video (at least in the case of SDI). So basically all the “chroma smoothing”, etc., is done in the deck, and not in the software decoder, so you won’t be waisting CPU cycles doing the above-you can simply edit with the uncompressed footage and go on from there.
Hope this helps,
