Intesity Pro for use with PPRO CS3
I left an email via Blackmagic Design site, requesting information, and also in the Premiere forum here, requesting information, and even called support early on (Before most of my questions surfaced). So I’ll post here, and if someone would contact me here or off line, I’d appreciate it.
First of all; I’m very happy with Premiere Pro, though their support of only DV and HDV is kind of limiting. Intensity Pro would seem to be a solution, but it is not exactly clear what speed raid I really need for it.
I’m also not trying to slap at anyone here, because I’m looking for a solution….. It’s only after not finding the answers that I would seem to need, that I post here.But it turns out that I’m ready to purchase a new computer anyway, and so Intensity Pro could theoretically be a solution after all.
Here are my issues:
Camera’s:
It appears that the move is on to HDMI ouput on camera’s. This is probably good as then you don’t have to write codec’s for multiple subsets of MPEG4 video files. HOWEVER:
Even with this, it is UNCLEAR what bandwidth is necessary for these captures.. With posts on the Intensity Pro site such as: “Online JPEG for Adobe Premiere Pro
On Windows, Blackmagic’s full resolution (1920 x 1080) professional quality compressed HD codec can capture JPEG AVI files in real time using Premiere Pro.” It appears that I don’t need a high speed Raid, but in the manual on Intnsity Pro I found online it states on Page 22 of the 6/07 Owner’s manual: “720P 59.94fps 4:2:2=106.8Mb/Sec 1080i 59.94fps=120Mb/Sec [Both NTSC]).
These two statements seem to be in contradiction with one-another, (Especially so since most of the new camcorders are doing 13-18Mb/sec to their respective storage media’s).Camera Machine Control issues: Firewire is being dropped from certain Panasonic camera’s, being replaced by USB. Is machine control via USB being supported by Intensity Pro edit system Plugins for Premiere Pro CS3? Panasonic cannot tell me.
Data Transfer rate on HDMI captures in Intensity Pro.
If I’m using a Camera that is making 18Mb/Sec data rate in it’s HD 1080i 59.94 recordings, but I must make room for drive overhead of 107–120Mb/Sec (remember-this is only one stream of video!) Doesn’t this seem in-ifficient?
Where is the JPEG compression the website is talking about?
(It does not appear to be in the manual I downloaded.)Computer issues. I’ve seen the limitations on motherboards on Intensity Pro website. If I compare these limitations to Adobe’s Premiere Pro Specifications, the two lists are not compatable. According to Adobe website, It would seem that I’d need 2 dual Xeon’s at 3.0Ghz or higher (Which is what I’m planning on purchasing) for HD video… The motherboards that satisfy Adobe Premiere Pro do not satisfy Intensity Pro!!
NOW WHAT???I have further issues with a new system — based upon my first concern — bandwith of storage needed. What speed array, and on board controller, or external controller? It’s Not Clear What I need to prevent ‘problems’ down the road.
Let me be perfectly clear here: I’m not trying to badmouth anyone here, I’m just trying to make a decision on new hardware that will work with Premiere Pro and Intensity Pro, without ending up on a dead end street with a system that “Almost Works”.
I would be willing to take this conversation off line if deemed necessary.

Hi Jan,
The JPEG (MJPEG actually) codec requires about 12-14 MB/sec.
The high data rates in the manual refers to the uncompressed codecs.
The HDMI video output from the camera is an uncompressed video stream (not data) so the data rates the camera records in is irrelevant as you’ll be capturing to another compression codec.
There is no machine control via USB, only firewire.
2 Dual Xeons will certainly work with Intensity Pro. Just make sure you have a x1 PCI Express slot on the motherboard.
Your setup will largely depend on the type of codec you’re working in. If you’re working only in the MJPEG format we provide, then a single SATA drive is more than capable for captures. Obviously, the more drives you have in a striped array, the more streams you will be able to playback in real time.
For uncompressed captures, your media drive must be able to keep up with the required data rates. Normally, a 3-drive striped RAID0 array will be good for capturing 1080 uncompressed at 8-bit. We recommend using as many drives as possible as the SATA drives will slow down as they get filled up.

Thanks for the quick and through answer Kristian!
Want to verify one thing just to be certain:
I creat a 1080i 59.94 or 720p 59.94 session, and capture via the HDMI cable from the camera, and with the captured files will be ~14mb/Sec which PPRO will use in an un-compressed 720p or 5080i session, not HDV, Right?
(Darn Panasonic for removing Firewire!)

The size of the captured files will depend on the codecs you’ve used.
Uncompressed will be about 104 MB/sec for 720p and about 94 MB/sec for 1080i50.
If you’re looking at 14 MB/sec, then it’s probably going to be MJPEG which is a compressed format.

By compressed format, are you saying HDV?
I’m trying to determine (without seeing or testing the hardware) what it does….
So I’m correct that the compressed format is HDV, right?

Nope. I’m referring to MJPEG which can be used for both SD and HD compression. This is a full raster (1920×1080) codec.

I am not sure where I should post this question but I thought I would start here… I have a new Mac Pro loaded up with 2TB of disk, 4GB of RAM and a Cinema 23″ display with the intention of doing kick#ss home movies. I have a Sony HD camcorder that does AVCHD, so I bought the Intensity Pro card to capture uncompressed HD video through the HDMI interface. I have the Adobe CS3 Master Collection which includes Premier Pro CS3.
Here’s the problem… I cannot get Premier Pro to capture ANY video at all. Can you please help or point me in the right direction?
Thanks in advance for your assistance. I am REALLY frustrated!
