Blackmagic Intensity problem with AppleProRes422(HQ)

HDV as in tape from a cam? it should be captured straight to the computer over firewire to 1440x1080 .m2t files. 25mbps mpeg-2 with mpa audio.

Thanks aedipuss, but confess I am still confused. A friend has an identical setup to me - MacPro, Intensity card, Sony HVR-VIp camera, shoots with the progressive option, and has had no problem importing via HDMI with the Intensity card, at 1920x1080, which is the reason why we both bought the card in the first place, after a techie colleague put us onto it precisely because it allows the captuire of the larger frame size from tape. Only difference is she doesn't use the Intensity-labelled presets as they all say NTSC even when they are 50, or 25fps. Thinking this might be the problem, yesterday I made a custom preset at 1920x1080, but it still delivered the smaller frame size. I will try another custom preset to see if I can get around this.

what the "techie" doesn't seem to comprehend is that the tape only has 1440x1080 on it. up converting to 1920x1080 in the cam to display, capture and re-render to 1920x1080 gains you nothing except lower quality. the HDV video has a flag in it to display at 1920x1080 already without any conversion.

The only way to capture true 1920x1080 off that camcorder is to capture live not off tape. You would need the Mac Pro at the shooting site connected HDMI.

Thanks aedipuss and edDV for clarifying this for me. Sorted the frame size problems by downloading Snow Leopard fix from Blackmagic site - don't know why but it worked, and now I can capture at either 1440 x 1080, or 1920x1080, but which is, from what you are saying, interpolated, and therefore not a good idea.
