AJA & Blackmagic use same UC right?

August 16, 2007 at 5:57 pmWell…I DO have the Multibridge Pro in a test machine at the moment. But, I can’t get it to work. Installed the drivers, and nothing. So I am having issues getting it to work and I’ll need to contact their tech support (wish me luck).
AND…I will have a DVCPRO HD deck over the weekend. SO…what I can do is capture DVCPRO HD native…then capture DVCPRO HD via HD SDI with my Kona LH, and if I get the Multibridge working, capture with that as well.

August 16, 2007 at 6:00 pmSean ONeil said he did. He said he does it all of the time.
But I also wonder if Mattso is correct in thing Sean may have all Intel machines and, because of his speed advantages, may not be seeing dark green RT bars when cross pollenating?

August 16, 2007 at 6:48 pm[JeremyG] “Holy cow, the jig is up. I am glad someone else has said this, because no one seems to believe me that capturing through an HD SDI pipe (or even SD SDI) has advantages, and I am not just talking about RS-422 transport. HD SDI is HARDWARE not software. WIthin the deck are little electronics that are meant to push every last bit of quality out of the DVCPro HD tape and into the HD SDI. Hardware conversion almost always do a better job than software.”
Sorry guys. It’s just not true. Sure, hardware conversion is better than software conversion. BUT, hardware conversion is not better than NO CONVERSION AT ALL – which is exactly what firewire xfer is.
Capturing DVCProHD over SDI takes a hit. Plain and simple. One could subjectively say that hit actually looks “better”. Whatever. To each his own. But I think people should use filters for this kind of creative alteration, as oppose to recompressing lossy video.

We will have to agree to disagree.

My machine has a Kona. Every other machine has a Blackmagic. We work with P-JPEG and now ProRes. Nobody here has seen a dark green line.
That doesn’t mean Matt won’t see one on his machine. Anything could be happening there. Some weird QT plugin that got installed years ago. Who knows? Some Cinewave thing from before. Anything’s possible. But this theory you guys have that video files captured from BMD and AJA are different from each other – that ain’t it. I promise you.
Look at the DV sequence settings for “Kona DV” preset… oh wait, there’s no such thing. Notice how the Kona DV Easy Setups use the same exact sequence presets as regular FW DV. “DV NTSC 48khz”. The same exact sequence settings used for FW capture on a system that doesn’t even have a Kona or Decklink.
Here’s a 1-frame clip of an Uncompressed 8-bit 23.98 movie captured using a Decklink Extreme over a year ago (long before this place even had a Kona):

August 16, 2007 at 7:15 pmGreat thread, guys thanks.
Bottom Line… shouldn’t be an issue… but it is with my old machine. fine. I can live with that.
We’ll figure out what kind of Hardware Christopher’s going to get in the comming days.
And no, i don’t have millions… only gazzilions. I divested myself of US currency when Bush took office. I only deal in Clams now.
The Checks are in the mail boys.thanks again

Yes there is, It’s called 8 bit to dv.

That’s an Easy Setup. There is no “8 bit to DV” sequence profile.
