Raavin, the PAL or NTSC-res cameras I've looked at haven't been much less expensive than the HD camera I'm using (which was around $1000). It seems that 720p is kind of the "sweet spot" pricing wise -- more resolution makes the price go up very quickly, but less resolution doesn't cost very much less.

Steve might have more info on this, but I've seen a lot of NTSC-res cameras that are actually much more than $1000, and I'd imagine that the average price would be at least $800.

Basically, if you're going to go to the trouble of doing all this just to get an image, why bother with SD?

Sorry to be a pain Ben, but what camera are you using?? I just got through all of the posts after 3 days and it's going to drive me nuts. I thought the camera setup that Obin was using was around $4k US.

Here in Australia, a new XL1 is around $8k plus AUD and a lower range 3CCD camera like the XM2 is still $4.5k. As long as it was under $2k I think there would be heaps of interest. That's as much as a reasonable handycam.

Raavin,

I'm using an SMX-150c from Sumix, which operates over USB 2.0. For right now it's 8bit at 1280x1024, up to 27.5fps at full resolution (and 40fps at 1280x720). However, the company is developing new firmware and software for the camera to enable it to do 10bit -- possibly 10bit log from 12bit data. Anyway, it costs around $1000. I think Obin's camera is actually around that price too -- it's just that his camera necessitates the purchase of a CameraLink PCI board and some expensive software (if I understand correctly). Although he's working on his own software too.

If Sumix can get 10bit out of my camera and address a few usability issues with the software (they're working on it), I think it would be a great alternative to prosumer gear like the XM2 for certain projects. Even at 8bit, downsized to DV-resolution, the images I'm getting far surpass what you can get with prosumer cameras.

Juan, that sounds like an interesting setup, but it would necessitate the creation of an alternate bayer filter for the sensor, and from what Steve just said, it sounds like that's in the US$1,000,000 range. A bit out of my league. :)

---a capture with CineLink...opened the RAW file in photoshop convert to 8bit and apply a bayer filter plugin

Original RAW file:
http://obin.weet.us/Rec00001.raw

Ben can you write a plugin that allows AfterEffects to open that RAW file and apply a Bayer filter on it? I think it's a 10bit file...not sure..should be the same as the last RAW file I posted

If you can get it into AE, you can apply my filter. But I've never coded an import plug-in before...

It should be relatively easy to write a command-line converter for your RAW files. All you need to do is slap a 16-bit TIFF header together with the data, and you've got a valid 16-bit TIFF. Could be coded in an afternoon...

want to take a stab at it Ben...it would help out this project a bit...;)

I am NOT a code writer ;)

Or maybe Scott?

what about a format that is native 10bit? or is the 16bit tiff just as good because the extra bits are zero's so no extra space is taken up?? ?

Hey Obin,

What bayer filter plug-in are you using?

I'm planning a command-line "Convert" app as one of my next phases. It will be open source, so Obin's developer could add support for their RAW format to the app. Once I have made some progress I will probably start a SourceForge project for it.

streak ( duplication of part of image )

Obin, Looks like a memory pointer was somehow reset to a point higher up in the picture during readout. That's why it is duplicating the image.

Ok who knows of editing software that can edit 10bit?

I am back to square one....we don't have a way to edit this stuff! LOL..funny that could be...

Rob are you fully in love with the SDK from Epix HA HA HA ;)

we are haveing troubles with it left and right..crappy stuff...did you find a way to capture the RAW black and white image and write that to disk AND display a live color preview?

Speedrazor is supposed to support 10 bit, it supports Cineon images too...

Oh sure, it's the easiest to use and best documented stuff I've ever seen ... not

I tried Speed Razor once on Cineons. It didn't like it, it had some kind of "VGA memory" error. I think that SR is very video oriented and they tried to use the graphics card to do a bunch of stuff. I guess that was the way to do things back in those days.
I think SR is a dead product these days.

Let me know if someone does know if it works on XP with the latest directX installed, and with an Nvidia card. Maybe they only worked on some odd ball video card, I don't know.
