RED alternative, a true indie cam possible?

I guess I can tell you what I have in mind as I have applied for a patent
and any copies of this idea would just finically benefit me anyway.


Fact:
Memory (both ram and harddrives) have gotten cheaper and bigger the last years.

Only reasonable thing to do with digital video a year ago was to compress it,
though adding hardware cost and editing problems.


Now days you could store 12bit (4:4:4) RAW bayer patter cmos data directly
to relative cheap ddr2 ram.

What if you created a pci-e 16x card that have 16 slots for ddr2
and one 2k high-end cmos sensor.

4GB x16 slots = 64GB

1080p Calculation:

2 073 600 pixels at 12bits each = 2.97mb
* 60 frames = 178.2mb/second

That shows that you could have 6 minutes of continues filming.

The next step from here is to move it to a more permanent storage:

A internal 1 terra byte 3.5" HD,
that dumps the 64gb ddr2 ram between film takes.

or a docking station that have eight 1 tb drives in raid-5 configuration.



So you would need some type of board that have hardrive ports, usb/firewire ports, hdmi, cpu and operationg system.
That have already been created and is called a computer motherboard.

This 17cm x 17cm board have everything a digital camera could need.
and the very important pci-e 16x slot for the cmos module.
It would cost a fortune to trying to create somethink like that from scratch.

End-user can replace mobo or cmos module as technology improves.
With an open source Linux operating system and open source camera software,
this would allow anyone to tinker with it and make changes.
A true hobbyist camera.



The problem is to locate a source for the cmos.
4K cmos are in the works but will only be available to the elite with an initial $250k membership fee.

This 2K one could be a good start.

What cmos would you like to see be used?
What do you want to camera to have?
 
I do not get what should be new on this idea!? It is just not very practical having completely uncompressed files to edit unless you have a very powerful editing suite $$$$$$$$. Similar approach, but much more practical ---> RED camera
 
Recording to a terabyte RAID array of flash memory would seem like a better idea. The device would be a heck of a lot smaller, consume less power, and a terabyte of flash memory wouldn't cost all that much more than the DDR2 memory for this massive RAM buffer machine.

You would need a faster interface than SATA to make an 8 drive raid 5 array very useful (for speed). The newer terabyte SATA drives already achieve close to 1mbps sustained thruput. Not much point in using more than 4 or 5 drives in the array, aside from increasing total size capacity of the array.

Really though, simply using a solid, visually lossless codec from the get-go can result in a finished product that is indistinguishable (to the human eye) from a product resulting from a lossless workflow, and is a whale of a lot less of a headache to deal with.

Who knows what the patent office might do. They did give somebody a patent on digital recording of 24p material, so who knows, maybe they'll give you a patent on insanely huge disk cache devices.
