Tell me what you think about this box camera built "specifically for digital cinema/tv" . . .

Looks incredible, but I imagine it costs a lot?

Ronald,

I hope you can make some use of it and if you think any of the ideas there might translate to the projects here please post.

Laurence,

That is a serious camera, very big on the WOW! factor only trouble is it’s also very big on the price factor as well $85k as far as I know.

The price for the bare 4-HD sensor is around 50K $. Olympus has developed one type of HD camera based on such sensor.

For alternative choice of camera head, pls. check www.elphel.com

Elphel's camera use the micron's 1.3 Mega and 3 Mega sensor. It can output Motion-Jpeg stream with a speed of 22 fps@1280*1024, 31fps@1280*720.

With Elphel's camera, it is much easier for storage, because the video has been compressed before output, but hard to display: you need additional CPU capacity of decoding the JPEG picture. Generally, To display the video with full speed and resolution, a 3G P4.CPU is needed.

I saw this camera, CCD, 2048x2048, cameralink. according to my (suspect) calculations it will do 60fps at 2048x1080. I could be wildly wrong here, so take it with a pinch of salt. Neither have I seen pictures from this camera.

on the upside, f-mount, and a 4/3" chip.
on the downside, costs a little under $6000.

How on earth are you able to get 60 fps at 2048x1080 from a sensor wich runs at 8 fps at 2048x2048 ???

Generally, the CCD sensor's data rate is lower than that of CMOS sensor.
if the fps is 8 at 2048 by 2048, it will less than 16 at 2048 by 1080
I have find some CCD sensor with very high data rate, but such sensor is only monochrome type, seems only designed for the 3-CCD camera.

well, i said i could be wildly wrong. if you mail them they can send you out their calculation formula.

The limitation for fps is the maximum frequency of the sensor's clock. Normally, with partial scanning, higher fps can be achieved, but the total pixel is output in certain time is almost constant ( only a littler lower for small window).

Merry Christmas all!

The new "Motion" series cameras from the RedLake is quite interesting: http://redlake.com/high_speed/index.html.
High speed (650fps!!!) at 1280x1024 with 12 micron size pixels. Sensor size is 1", larger than s16mm and closer to 35mm movie frame size.
The cameras have internal memory (4G) where data can be stored before dowloading to laptop computer (PC and/or Mac!!!) via USB cable; no frame grabbers and the host computer is not a high spec machine.

Merry X'mas!

The RedLake should ( I guess) the Micron's MT9M413 sensor. Such sensor has a sensitive area of 15.4mm by 12.3, smaller the 1/4 of 35mm film.

4 GB memory can store about 100 second video in 1280*720*30fps*10bit.

From the RedLake's brochures I understand that you can transfer the data to the computer as well, by-passing the internal memory. I must read the manual closer to see if that's possible.

A recent re-visit to a camera site came up with this:
http://www.visiblesolutions.com/phantomv9.html
A bit scary: global shutter, 1000fps at full sensor (1600x1200), 600 ISO/color, Nikon lenses, optional 12G on board memory will deliver acording to my calulations ~ 4.4 mins@24fps (6400 frames at full resoultion - same as the 400 foot magazine on a 35mm camera), optional continuous output to a external storage device via Gbit ethernet, firewire and SDI output (PAL, NTSC)...
Am I dreaming? Correct me if I'm wrong!
Should find out the price of this toy... Hope is not $$$$$

Uh . . . wow . . . this thing looks tastey.

Someone find out the price please.

I guess, 10K$

I think the Phantom cameras have been mentioned before and I think they are a lot more that $10k.

I hope I am wrong and have emailed them for a price list I will post when I get a reply.
