Sounds like the email server is down. Unfortunately we can't restart it remotely, so it will tomorrow when you get your emails. Sorry.

It WAS the HDMI cable! It wouldn't allow a 1080 signal, just a 480.

ENERGY HDMI CABLE = BAD
VELOCITY HDMI CABLE = GOOD

Terence, you are a rock star! If you hadn't of joined this thread saying how yours was working, I would never have given it another shot, especially since Black Magic confirmed their HV20 wasn't working with the Intensity either.

So everyone who's having problems, time to pony up for some new HDMI cables. I'm staring at a glorious 1920x1080 HDMI signal on my monitor right now. COOL!

Hi Derek,
I had a request for you since the intensity card is working with you.
I was wondering whether capturing a already taped footage over HDMI has some advantage compared to firewire or not.
Can you do a comparison and let us know?
Thanks!!

I'm planning on it for sure. Unfortunately I don't own a resolution chart or color chart. I went to price them out today and I couldn't justify the $300 they wanted. If there's anyone out there in Vancouver that has a Sony or JVC cam with HDMI and wants to do a shoot out let me know.

Or is cineform expanding it the 8bit to 10bit anyway? I, too, am very interested in whether core2duo mobile processors in the 1.6-2.13ghz range are adequate for capturing from the intensity from an hv20. Perhaps in low quality mode? 2.33ghz core2duo mobile cpus are $600+ just for the cpu, and the 2.0 ghz version is like 1/3 the price. I guess overclocking might be an option for some. But if it is not necessary for capturing, it could make a big difference. I am interested in building a portable miniITX capture device using the intensity, so knowing exactly what cpu will give us the results we want for the lowest price will help a lot. Unfortunately I doubt many ITX boards can be easily overclocked. As much as i'd love to buy neo hd and an intensity card and test it on various mobile processors, I dont think I have the disposable income to afford it if the cpu's I buy dont end up being enough for reliable capture.

NEO HD seems a bit pricey even for all the things it does. David, any cineform fanboy discounts for posting on forums all day about how great cineform codecs are? :P Is it possible to use NEO HDV to capture from the intensity? will that just force resizing to 1440x1080? or are there also other limitations?

What mini-ITX motherboard can you recommend?

Thank you in advance.

That is a good question. I'd tend toward the aopen boards since they have a built in power supply... although I suppose they still need a regulator for the 19v battery input... I've just had a bad experience with an itx board that eventually burnt out after i ran it off an m1-atx psu for a few months. Then again it might have been the lack of active cooling. The MSI doesnt have dual channel memory, and people from cineform have often said memory bandwidth is a big plus for capturing to their codec. Other thoughts are whether to get a mobile cpu or a desktop cpu. It appears the commell lv-674 can take core2duo desktop cpus, which are a lot less expensive and allow for more options than mobile cpus. It's hard to know about these itx boards though, they are not nearly as widely used and documented as ATX boards so troubleshooting could be problematic. But definitely look for anything that has pci-e x1 and dual channel memory. And if you are going for a mobile cpu, make sure the socket is right.

Check this mini-ITX mainboard based on intel Q965 Express chipset:

Well that would be a great option if it had pci-e....

You are right...
But now we can see a lot mini-ITX "santa rosa" based mainboards.
Like this http://www.ipc2u.de/catalog/P/PE/35776.html

I dont think that is santa rosa :)

Santa rosa is a designation for boards that take mobile cpu's and meet particular specifications. That board is LGA 775; santa rosa would be socket P i believe. Chances of finding a socket P CPU for sale right now arent great i would imagine.

but you are right, hopefully we will start seeing santa rosa boards. Probably not for a few months though. ITX is usually the last form factor to get new technologies.

My another mistake...
And next candidate: http://www.aicmicro.com/productdetail.asp?id=32090

i looked into more or less every mini itx board available. my conclusions was the a-open seemed to have the best setup for something like hdmi capture.

its got a pci express x1, sata 300, dvi, firewire. most every other board is missing something as they are geared to industrial use. the other benifit is that its a-open, and available everywhere and will be simple to get serviced.

on another note.. i got my black magic card, and may have found the answer to the "is the hv20 only 8 bit" question.

it doesnt matter.

the black magic hdmi input chip (analog devices AD9398) is only 8 bit. to some degree, who cares, its the only solution for now, but they do advertise it rather specifically as 10 bit, and its definitely not.

now ive got to work out my expresscard box.

Yeah, I recall cineform tended to recommend the aopen boards a little while back when they were building their si-hd/2k body. Seems like itd be a good way to go. Probably a bit more documented than the industrial models in the same range. Anyone know a good way to run one of those off battery? I assume an 19v li-ion would be a problem as its voltage drops with use. maybe one of these would work?

take it apart and fit it in a chassis?

unfortunately that particular pc is of no use for the black magic card. it has no pci express, or expansion capability at all.

hopefully their mini itx version will follow soon, which should be very very useful.

terence

while it is not really mini, i would recommend the shuttle SD39P2 .
It has everything you need. You need to find a VGA PCI card since the only PCIe will be busy with the intensity.
