Obin, what board did you use?

Those 855GME boards are using AGP, it's just using an on-board chip.

Why all the problems when a Pentium M at 2.0Ghz is a very fast chip?

This all seems very confusing.

Finally, what API are you using for display? OpenGL, DirectX, directly to the framebuffer?

some directx and some framebuffer

board I used was a fullsized atx board with built in video display like the micro boards have..it sucked BAD very poor performance...

Can you give me processor and chipset specs? That would help out a lot since there are so many ATX boards out there.

What are the prices on the Altasens chips? I can't seem to find that in the mass of posts.

Also, why are the altasens chips considered to be so great? Do we have any tests? What is the signal to noise ratio and dynamic range?

Obin Olson what camera did you capture these with images with.

Obin, I just figured out it's your footage that we had put on a movie theater screen here in OC,ca. When I got the clips I never knew who posted them etc. Now I do. Your clips looked amazing on a 30 to 40ft screen considering the were just samples.

I'm not sure about the chips themselves, but for the cameras based on these chips, expect to pay around $4-6K.

Hey Obin,

You wouldn't mind telling us what the integrated chipset you were using was, would you?

I know you're saying the small boards are no good, but I'm really curious to know what the specs on the board you were using was, as I would like to avoid it too.

There are too many integrated chipsets out there to simply say that "such and such is always bad". Knowing the processors and chipset would be a huge help in finding out just what is needed performance-wise for these devices.

Thanks.

well it did say SIS on it ..not sure what chipset I will look and see if I can find a box

BTW the 3300 has MUCH better colors then the IBIS5 chip ...wait till we get this thing going ;)

Looks like CIneLink is working now..maybe..so far testing tonight is good..good framerates and it looks like we are saving on 2 disk drives 10bit raw files..I have trouble opening the raw files..working on that now...

I would put a .DNG header on them. Then you can demosaic them in photoshop.

of course, how is everybody doing their RAW files, little endian or big endian?

the TIFF spec says that any bit depth that's not 8 or 16-bit has to be big-endian for the way the bits are packed. The file itself can be little endian, but the image bits must be big endian.

If that's the case, then simply putting a .DNG header on a RAW file isn't going to do much good.

Wayne,
Thanks for the reply regarding the audio. I think that this issue should go on a different thread, as some working cameras are pretty much out there. Speaking about A/D converters I found a standalone converter box (look at ST/SB ADC/Digital IN/OUT although th DI2000 has higher end features) that can be part of the modular camera concept.

Jason: Rob S. and myself are using Motorola order for the IHD
files. So that would be little or big (I get confused on those things)?

I guess little is Motorola and Big is IBM.
