Sumix 2/3" 1920x1080 CMOS

Alex Raskin · July 31st, 2009, 11:56 AM

Eric, Johanes, Daniel et al - so far, what do you think of your Sumix camera.

Would you recommend it as studio head?

I have Zeiss 100mm Macro with Nikon mount - would that be a good sharp lens used via C-Nikon adapter?

How do you record sound?

Do you transcode DNG to Cineform for real-time editing in Premiere Pro?

Thanks!

Hi, I haven't found a way to convert those sumix raw files to DNG and not even that avi uraw to something that mac FCP can read* (I got bored), so untill I find solution for those, I can't recommend. But I'm mac user and don't know much about PC...(* if I dont count that very poor VLC player convert)

for sound
I have now Sony PCM-D1, but when I'll have time I try to do this kind of system (6ch target). I have already lynx AES card.

Does anybody have a .raw file for download. I would like a sample file to try and process. Thanks in advance!

If someone has some RAW frame files from Sumix I would be interested in that also.

I have DNG from Acam dII, SI-2K, and Kinor-2K I have been using to develop a new de-Bayer program for my "freeish" uncompressed DI system.

It would be nice to have an option in my menus for Sumix as well, there examples could use some additional color grading, the CC part of my system could clean up the color maybe.

I hope to have my de-Bayer out after April 2010 maybe, its about 60% written for Digital Cinema use.

To get RAW data from the Acam dII files you just skip the 512byte header and read the 12bit packed (two pixels in three bytes) image data for 2048x1092 resolution, there is black on the sides since it is only about 1920x1092 image.

I am still working on my de-Bayer program for Digital Cinema use.

Its about 80% done, so I may post it this summer.

I am working on DPX support now so it should be able to convert true RAW sensor data to DNG or DPX, as well as TIF and BMP and a few other file types with color correction.

I made some changes to my "freeish" DI/CC/NLE/MIX program so that the CC control screens can be used on computers runing Windows XP Home (tm) that have problems with the higher resolution SVGA modes, it can not be used in "Safe mode" 640x480 when the other modes do not work, so it is at least usable, you can still process 6K+ TIF frames, its just the preview that is limited on some computers. Its up for download at my web site.

If anyone have true RAW sensor data and would like their Digital Cinema camera supported you can contact me by email and I can look into adding an option for your camera in my setup menus.

Someone saw my post and sent me a SUMIX *.RAW file for testing, and I added some support in the de-Bayer program I am working on, but the sample file had the in camera processing ON which prevents getting good results and my making a calibrated preset for the color correction.

If someone can send another *.RAW file please do these things:

1) White balance, disabled.

2) Median noise filter, disabled.

3) 12bit uncompressed format.

4) Gamma correction, disable.

5) RAW size 4GB or less.

In other words, only the sensor data in the file, no processing at all.

My email is in my previous posts here...

I added some SUMIX "RAW" 12bit support to the de-Bayer program I am working on, but so far I have not gotten any real True RAW data without the gamma correction, white balance, and noise reduction. So I am still waiting on that to see what the data really looks like. I asked someone at SUMIX (tm) for shots of 90% White, 18% Gray and 2% black cards and some colored subjects such as an orange to set the saturation and ISO curve with, but they did not reply to that request.

Another issues, is how easy is it to fit a good OLPF+IR/UV cut filter to the Sumix camera, all I have seen on their web site is a simple IR filter, but an OLPF is needed to reduce chroma moire and aliasing, so I am not clear why they might not have addressed that issue?
