I can't see how DirectX or DirectDraw are limited to work with AGP.
It is a graphics standard to talk to your graphics card and should
work just as fine with AGP, PCI & PCI Express. Otherwise there
would be no reason for 3D cards to be out on all those platforms!

Eric: no, it was delayed and from the last I heard it should be
shipping soon. But, this is a highly specialized market, so delays
can and will happen. If you can't be patient this game is not for
you....

trying to make headway with DFI and Epix still....

in the meantime.....

We are working on getting 16bit tiff export..we had it but found out we had tiff files that had been broken down to 8bit then saved as 16bit..this will not work...we need an SDK or codec that will provide FULL 16bit data.. anyone know of a 16bit codec/SDK I can send to our programmer that will deal with the data without loosing bitdepth?


thanks for any help with this one...


I can post a raw file for anyone that needs it...

Doesn't libTIFF support 16-bit files?

I am not sure Jason..can you give a link and I will forward that

Ok the LIBtiff is what we are using now...seems that we are still getting the 16->8bti->16bit issue..I have sent an email to Frank over at LIBtiff...lets see what he says...

From Libtiff:

Obin,

Hmm, depends a bit on which SDK of mine you mean.

Libtiff will read and write 16bit TIFF files losslessly, but you
must take some care not to use the RGBA interface (which
converts to 8bit). Instead use the TIFFReadEncodedTile()
and TIFFReadEncodedStrip() functions. Libtiff does not provide
any real "processing". It is just a TIFF read/write library.

http://libtiff.maptools.org/

I also have an SDK called GDAL for reading, writing and
operating on Geospatial raster data. It supports 8, 16, 32bit
and other datatypes and can preserve the original data type
throughout processing. However, based on what you have said
I suspect you are looking for a generic image processing
capability, not a geospatial one. If so, GDAL likely has
little to offer you with the possibly exception of being
somewhat easier to use (though much bigger) than libtiff.

http://www.gdal.org/

Best regards,

good stuff.......

If all else fails it wouldn't be too hard to write a TIFF writer
yourself (or your programmer). I wrote a little TIFF reader (which
is much harder to do) a while back that supported only limited
amount of options, but did work. TIFF is a more complicated
format than say TARGA, but for writing it should be pretty simple
to roll your own.

ok so at the moment we have working 720p 12bit 4:4:4 preview - capture - record

I think I will have a working 16bit tiff export in a few hours.. once we have that I will shoot some more footage for everyone to check out and play with ;)

still waiting for DFI

DFI is sending me a new board for testing - if that does not work I will be in contact with the BIOS programmer at DFI


we should have tiff working now. I am not at the office so i don't know if the office machine has an update for the tiff stuff in the inbox...

I don't have those, but I have been meaning to get around to checking out this service for the group:

http://www.100webspace.com/

I'm sure it is not the only one, and something might have a bit more GB. Pity we can't setup a download network (like they do with program downloads) using people's accounts (free accounts in this case).

By the way what happened to Rob.S.

Going to email him?

well well ..the 64bit card is working now(after a re-install of XP)..we have Xcap running the 3300RGB camera at 79mhz! at full resolution with a RGB color display 12bit! this is good news BUT we are now having issues with RECORD from our software..seems that after about 5 sec of recording the thing starts to slow down the preview and then will FIFO on this card also...the pci-x slot is a VERY fast slot and the fact that Xcap runs at 79mhz 12bit tells me this is OUR issue not the board or hardware..we are looking at what is going on...more when I get it...

update: looks like it could be an issue of the XCLIB SDK not supporting the 64bit card yet..or we have an old version with old DLL files...I hope!!

bought a 25mm Pillard film lens on ebay for testing and it's CRAP..god it's so soft!! anyone have some idea for a good cheap test lens?
