I´ve just started uploading some video files and will post the links as soon as a clip is online.

In my opinion the MJPEG capture directly from the cam (not from tape) is at least as good as the hdv capture (firewire)... no more problem with parts burning out.

Ray Bell September 20th, 2007 08:36 AM

Rolf, I'm not familiar with your Camera and how it outputs the footage
but it may work somewhat like the Canon HV20...

Ingesting footage using a HV20 and the Intensity card....

The footage is 1440x1080 if from tape, via firewire ( not intensity )
The footage is 1920x1080 if from tape, via HDMI ( Intensity )
The footage is 1920x1080 if from live, via HDMI ( Intensity )

As shown above, the HV20 will upconvert the tape output of 1440 x 1080
to 1920 x 1080... it has nothing to do with the Intensity card....
The conversion is in Camera....

again, not sure how your camera handles the output........

Here´s the first clip:
captured directly in MJPEG with auto exposure...

I got the Canon XH A1... it has no HDMI, im using the component signal, so the signal is converted in the camera from digital to analog... the intensity pro then makes it digital again...so it could be the intensity PROs fault.

Robert Ducon September 20th, 2007 11:42 AM

By specifying the signal signal, I mean resolution and frequency (hertz): i.e 1080i vs 720p or/and 60i vs 50i vs 23.98 vs 25p, etc. The camera's output is fine - just make sure the computer matches whatever signal the camera is outputting.

Both HDMI and Component will output the same signal that the camera is set to - just one technology is digital and one is analog.

Yes I know, Output is 1080i 25fps and Input is specified as 1080i 25fps...

the hdv clip captured from tape via firewire is online.
I recorded it just a few moments after the composite capture, the camera settings weren´t changed... iris on auto

Last but not least: I uploaded YUV 422 capture, i was just able to capture some frames so I just uploaded a single tiff file. I didn´t change anything at the camera but just closed the iris a little bit more than auto put it. Nothing done in Post. Some interlace lines are visible...

Some reviews state that the BM MJPEG codec softens the data. I have the BM Intensity pro just sitting there waiting for a new computer with PCIx .

Daymon Hoffman September 21st, 2007 07:23 AM

Thansk for the OP. And to those doing tests. As i'm one looking to get an Intensity Pro and hoped the Component capturing would be at least pretty close to HDMI. Just a quick Question from owners... can you chose any kind of codec to capture to just like most capturing cards?

You can choose between:
1. uncompressed (that is YUV 422 8Bit for the intensity pro)
2. MJPEG compression

that for the supported input formats ;)

I captured in Cineform from component. The picture was shifted to the left (?!) in the HDLink window, but fine otherwise.

Robert Ducon September 21st, 2007 02:23 PM

Depending on which application you choose to capture, yes. The application that Blackmagic Design supplies has less choices than using FCP Studio. So yes, you can get a good selection to choose from.

Robert you´re right, I forgot that I could capture in PPro...
So there are lots of codecs.

Alvise Tedesco September 22nd, 2007 08:53 AM

Hi Rolf (and all of you).
I just bought an XH-A1 (for an upcoming job I'll shoot in SD). Later I'll shoot hdv and I'm completely new to that.
Advantages with BM Intensity only relates to DIRECT capture (no hdv taping)?

I'd like to shoot hdv on tape BUT then move to a better intermediate codec for editing. I'm on FCP, so Cineform doesn't seem the better solution (recently implemented for Mac users, but looks quite complicated). Neither Prores 422 cause I need a compromise in system/disks requirements.

Suggestions appreciated!
