Blackmagic adds HV20, 25p, 1080i HDV support to Intensity cards
Blackmagic Design: Software Downloads:
This software release introduces support for Apple Final Cut Studio 2 and adds support for Apple ProRes, the the Canon HV20 camera, 1080i HDV playback, 720p25/50 DVCPRO HD playback with the Panasonic HVX-200 camera and general stability and performance improvements. These drivers support Intel-based Mac Pro series computers. PowerMac G5 series computers are not supported."
Since so many folks are so gung ho for the low cost Canon HV20, the $250/350 Intensity/Pro cards are a good match if you want to capture live over HDMI and skip the HDV compression. Transcoding to ProRes on the fly now appears to be a valid option as well - sweet!

PS - thanks to Greg Boston for pointing out the DVInfo.net thread where this was found.

My question is how does this skip the hdv compression. Isn't it compressed on tape? What is the image quality difference between capturing over HDMI vs Firewire?

...that's why I said capture LIVE - as in, live on set, lugging your Mac Pro to the greenscreen (or whatever) shoot.
Live off the sensor, never touching tape.

ahhh. that makes total sense now. I missed the "live" part. Now if they woud just make some portable hdmi input for the macbook pro.

Keep an eye out here:
http://www.expresscard.org/web/site/cons_wtb.jsp
This site updates pretty quickly regarding expresscards.
Hopefully an HDMI expresscard will soon be available.

On direct question (it was posted on some forum like DVinfo, ...) Blackmagic answered that they will not produce mobile HDMI expresscard. :(
Hmmm, so who will?

How 'bout something like this with an intensity card in it.
Magma Express
They claim 2Gb/s on the connection although I seriously doubt it, in the real world anyway. Still it's a sweet way to capture with a laptop if it does work.

Look carefully at the Magma data sheet. It is 2000mbp/s ie bits not bytes. They translate that to 250MB/s, so no unfortunately you don't get the full 2GB/s potential of the Expresscard standard, and can't carry 1.5GB/s HD-SDI data rates.
When Express34 was announced, I asked AJA and BMD about some kind of solution with that for HD - "Nope" from both camps.
AJA IO HD is best laptopable field solution.

But nobody's talking about doing 4k via expresscard! Anyone doing data rates that are too big for expresscard (> 5Gbs) can afford an Aja or whatever. Most of us are talking about HDV, a puny 25Mbs, right? So what's the hangup? Any HDMI input is required to support DRM, which expresscard does not (natively, at least from what i've read). It'd probably only cost a few thou to get some made (you can get a SATA adapter for $20!), but your first customers would be men in black suits with big scary briefcases. (hint: those are not portable editing rigs). Just my guess.
