to rai orz

Sounds great.
What chip was used?
How long did the whole setup take?
What was the cost of the project?
What is you're NLE editing path?
What lens mount?
Any chance of frame grabs, footage?
Would you be interested in building two more units for private sale in the uk?

I work for a production company in the uk looking to invest in its own equipment, having just secured financing from a company in Dubai. Please get in contact asap. either email me or reply on the forum.

To Steve Nordhauser :

Hello Steve, Do u have a release date for the 1920HD.
I didn't find it on your web site.

I think, I will order you this one and the dev kit.

Regards,

Flax,
The reason we are not putting much on the web site is that although the camera is real, the big box of sensors we have ordered is not real yet. I will let everyone know when it shows up.

It shoot 720p / 24fps (global shutter) uncompressed to HDD and the CMOS pictures are amazingly. It looks like film, not like video. -->>>

Well Rai, congradulations on finally finishing that camera, I'd like to see the website myself, and see what brand camera components you used. I have seen your 35mm site, is it the same? This new firewire defintion, is that 800Mb/s version B or 1.6Gb/s version?

Thanks

Wayne.

The same is true for clock frequency. -->>>

Thanks, I'll remember that, a 64bit slot is not one less 32bit slot. Would you know the cross compatability betyween the two versions (at least) of 64-bit PCI. I understand there was an older one before PCI-X in competition, or is there only one now? There is a bit of confusion as to what version the mainboard above has.

I know your piont about keeping device traffic off the PCI bus, very usefull for transactions and bandwidth.

Thanks

Wayne.

Wayne,
...no its will be a different web site, please wait a few days.

The new firewire. The only think i know from our electronic engeneers is: It will work with a 1080p /24fps camera.

Hardware Realtime Lossless Motion Jpeg2000

I have found a chip made by Analog Devices, ADV202 that can encode realtime Motion Jpeg2000:

Complete single-chip JPEG2000 compression and decompression solution for video and still images
Programmable tile/image size with widths up to 2048 pixels in 3-component 4:2:2 interleaved mode, and up to 4096 pixels in single-component mode
Maximum tile/image height: 4096 pixels
Video interface directly supporting ITU.R-BT656, SMPTE125M PAL/ NTSC, SMPTE274M, SMPTE293M (525p), ITU.R-BT1358 (625p) or any video format with a maximum input rate of 65 MSPS for irreversible mode or 40 MSPS for reversible mode
Two or more ADV202s can be combined to support full-frame SMPTE274M HDTV (1080i) or SMPTE296M (720p)

the link is:
http://www.analog.com/en/prod/0,,765...V202%2C00.html

If this chip would be on the camera or the frame grabber, then all of the storage problems would be gone....

Regards,
Alex

Me too.

Rai, is this a camera design you plan on manufacturing and selling yourself?

Realtime Lossless Motion Jpeg2000 encoder

And it costs 39$ per chip

People have been discussing these chips some time ago. Some people want to do FPGA instead. Without getting into the details of these chips the issues are. Where ever it has the power to compress it and can compress the right format in the right way. The format we are using for the moment is bayer single chip (different from normal single chip) 4:4:4, lossless compression (and whatever else we can add on latter). I this chip can do that then your in business. The other thing is price, putting this on a board could double the cost and finale price might be five times that. So if somebody does this it is fine.

Sumix is developing a compressed camera (and I'm sure there are others) for us, and Silicon Imaging intends to when a suitable FPGA becomes available. I am actually researching a cheap sensor (nice performance) that includes a lossless compression engine. The price maybe less than $100 all up per complete camera head with lossless compression (say $200 more realistically). But at the moment I think there maybe some artifical restriction. I am doing this quietly to see if I can get around the problems without certain parties blocking the initiative. But I have to get time in to do it properly.

Hey guys,

Talked to a sales rep at Epix today, and he said that the 64-bit framegrabber probably won't be shipping till sometime in January or February.

BTW, is Epix really the best board for us to be using? I've been looking at EDT's offerings and those look pretty good too. Right now their cameralink cards run at 32-bit/66Mhz for a total of 240MB/s, twice as much as the 32-bit/33Mhz cards.

I guess the only thing is if I use their cards I'm going to have to find a programmer for a custom capture app. Oh well . . .
