From what I know, the AltaSens check has far better image quality.
That is correct. Rob Lohman and myself have been working on a two-part system.

The Capture app (ObscuraCap) is like the camera's firmware and is designed to be as user-friendly as possible. It captures the frames and writes them in lossless, raw form to disk. Sort of a "digital negative."

The Convert app (ObscuraConvert) "develops" the raw files into formats that are more suitable for editing. It is currently command-line only, so it isn't quite so user-friendly. But it will be released soon as open-source (GPL) so a UI (and lots of other features) can be added to it.

Altasens - 1920HD
 

Marto:
The SI-1920HD is based on the latest Altasens (3560, not the older chips). Jason has all his facts about this exactly correct including the expected ship date with the newest sensors. Software supplied from us tends to be interface specific - either what you get with the gigabit or frame grabber and is very industrial. That is why we have people here working on cinema/broadcast solutions.

If you are not joining in on the development, I would suggest letting the people doing the software have about another month unless they invite beta testing. Right now the work is being done on the SI-1300 (720p), may move to the SI-3300 (1080@24fps) and certainly will end up at the 1920HD.

Thanks Steve,
Sound like i would have to wait, any way I don't know much about programing but in electronics and optics I can help,
please let me know if I can contrivute on anything.
may be desing and make a skeleton ergonomicaly for the camera because i have tools to cast and weld aluminum my best camera that I have used ( I'm using it at this moment) is aaton.
Altasens chips are working at with sensitivity at the moment with an acceptable noise rate?
I may can have involved a friend that do programing.
waht is the plataform you are building the interface on linux well UI I think is cross plataform unix osx linux if I'm not wrong.

The Altasens chip can go up to ISO1600 for sensitivity-that's very sensitive :)

ya but at cost of gain that means noise.
is there any test pictures ?
it is going to be sell by SI?

Yeah, I'm still droolling.

Marto, what you said is right, I would still like to find out what the bottom line is myself. I think Jason mentioned 100db max SN in the other thread, at that level you are putting 12-bits=approx 72db, allowing for 18db gain before it affects the bottom bit on average, that would be extrordinary (-ingly usefull).

Hey, does anybody know of a site that tells you the performance curves of human vision, the books here are not good enough? I am interested in how resolution, range and sensitivity of the luminance and chroma change with brightness.

I thought the noise levels of the chip when the gains were set to 0 to be very acceptable, and the dyanmic range was terrific.

Update:

Looks like I will be shipping the 3300 and Epix frame grabber off to the software developer for final work..we can no longer do all the testing via remote over the internet ..the software writer needs to see the issues with display and capture ...I will keep everyone posted as always ;)

Community Tech Update:
 

I have just posted a few things on a lowend camera in the tech thread, it's pretty high minded stuff, and not helped much by the 5+:1 Jpegs, but worth looking at.

In totally useless information:
 

Rob.s, can we have a RAW capture for this camera:

Now if we "dropped" into a few politicians' press conferences with that, it would sure solve a few problems (and make some pretty flat debate) ;)

Re: In totally useless information:
 

Sure, no problem. But I think the frame rate will be pretty slow, given a frame size of 100K x 100K :-)

Rob S. how is your capture app doing?

are you getting good preview framerate out of it yet?

I have been so snowed under I've barely worked on it for about a month. I'm getting around 25 fps on the preview. A little bit of lag, but not bad -- it's hard to tell exactly how much.

When you mean "not much", is it noticeable? Or is it just a slight amount that is barely noticable? Does the lag reduce if you turn off the color preview and simply go black and white?

BTW, do XCAP or StreamPix have lag in their previews? Just curious.
