Development Platform for DIY cameras

no problem call when you can

I feel like I've been watching a miniseries only to find that it's been canceled just as our heroes are starting to get the upper hand!

What happened with your development platform, Kieth?

Project direction changed and were going good for a while off the boards - then I had an accident recently which has put a complete stop to anything i've been working on but I'm working on it again. Not a development platform anymore, but can't give away much on what it is.

I'll just say this: We don't need no stinkin' computers! and thats a fact.

I can tell the sound of a guy getting serious.

You go!

Good luck.

Just keep an eye out and hopefully we'll surprise some people.

and no stinkin tiny flat lifeless 8bit 1/3rd inch ccd chips...and that's a fact

but the biggest "fact" of all: we don't need no STINKIN HDV CRAP!!!

LOL

I really wish I remembered what movie the whole "we don't need no stinkin' (insert stuff here)" pharse came from

I agree with that, it was only a means to a quick end, before we went to FPGA hardware (now done thanks to people like Juan and Andrey). Unfortunately it didn't happen, except in various bunches like Cinelerra.

Please keep us informed Keith, we are still waiting for cheap cameras.

When something more is ready their will be an announcement. Right now its a whole bunch of smaller projects that work that need to be put together and fine tuned and then assembled into a package that can actually be used.

Wayne Morellini · October 23rd, 2005, 04:58 PM

Can I ask something else. It is clear that the Sony HC1/A1 is a special little camera, apart from the HDV and level of manual controls. I was wondering if you would be interested in offering basic compression and component capture packages separately, over multi link Gige/SATA/Firewire800 interface to disk, or single interface with compression? In the market there is very few options for recording uncompressed from component, and compression hardware that can be readily used. They tend to be very expensive compared to what they should be. Is it possible to offer it for less than $500 with capture control?

Just something to think about?

Thanks

I'm not really into it mainly because it has been noticed that the rolling shutter artifact is apart when recording video from this camera in all modes. Any high motion horizontally skews just like back in the day with the orginal Cmos cameras people were experimenting with

EDIT: Someone else might be though and fixed a few typos

Not to open a whole-nother can of worms, but have any of the DIYHD guys considered stepping up to a full frame sensor and output 1920X1080 via subsampling. You could really get cinematic images with 35mm lenses.

Keith Wakeham · October 23rd, 2005, 06:23 PM

Full Frame requires a mechcanical shutter but with that aside these sensors have a maximum readout speed. Problem is you still have to cycle through all pixels and even if you can cycle them a little faster you still are likely below what you need.

Kodak just released a 39MP sensor and with their filters and stuff it should be great. Problem is it runs at 24 MHz so even with dual output and skipping lines (because you can't skip pixels) your not going to be able to do much because you can just barly read out 2mp @24 fps but you have no time to capture light.

Some are faster but have more output lines. I've though about it but for know interline or global shutter cmos is better for simplicity sake. But if anything gets off the ground then something like FF is sure to follow
