I know some of you have some experience of capture from the DVI out of a Mac into a Blackmagic Intensity card and was wondering if anyone could shed some light on my problem. Blackmagic will not ansewr my support requests so far.

I am outputting 1920x1080 from my MacBook Pro via DVI>HDMI cable. I want to capture this on my PC using the free Media Express capture software they bundle with the card. Although I get a capture the image is smaller than expected 1650x950 approx. Around this image is the rest of the capture making up a black border. 1920x1080 in total but not what I was expecting!

In my understanding I am sending 1920x1080 and trying to capture at this size but I am getting a cropped image with a 270 x 130 border.

Can anyone confirm if I should be able to capture 1920x1080 from my MacBook pro to the Intensity card on my PC and get a full 1920x1080 sized image.

Is this a limitation of the Media express software they give away free?

This may be a limitation of your capture software, or a codec issue. 

What codecd are you capturing to? Ive used the intensity to capture 

to Pro Res and to DVCProHD, and in both cases I got what I was

Capture was with motion JPEG into Media Express. Do you think I should have a go at making a jit.qt.grab patch for the capture PC? Will this work with the run-time installed on the PC if I author the grab patch on my Mac? I don't have Max/Jitter on my PC

I must say that even though I am having to correct the colour AND re-size what I am capturing the results are damn good! with a touch of sharpening and a careful colour/levels tweak great. But I want to know how it will look with the pixels I am missing.

You might want to give Adobe Premier, or Avid a shot, if you can get 

your handson them. PhotoJPeg should have no issue with capturing the 

full raster, so I am honestly uncertain as to what is going on.

I have little experience with Intensity on windows. Sorry ! :)

that is what I stated I was using in the first message. Are you using this from the DVI out of your laptop? Do you get a full frame 1920x1080 capture using it if you do? I get a border. I may try and make a jit.qt.grab thing for the PC on my mac run on the PC via the run-time. I may be barking up the wrong capture tree compatability.

Can I make a DX version on my Mac for my PC?

I captured 1280x720p usually since the intensity cant handle 

progressive 1080, but in my tests I did not notice a border @ 1920x1080

ah, sorry. misread your post. what version of the software do you use 

did you try to connect the 2nd output of your pc to the intensity?

ill make a test today with my macbook pro and a pc with the intensity

Capture is on a RAID PC Win XP using Media Express (version is the one included with their 1.6 software). This is fed by my Macbook Pro 2.16 via DVI > HDMI cable. Sending 1920x1080 out and capturing the same on the intensity with motion JPEG.

I am going to download Premier CS3 demo and see if it captures without a border

BlackMagic Design still have not got back to me despite my detailed support requests. If Premier works then Media Express is broken

good idea I will try that, thanks.

just did a 720p capture from both my MacBook and the dvi out of the capture PC and they both have the same border in the recorded file.

Good to know it works for others though!
