Convergent Design Flash XDR's File Format & Cineform at DVinfo.net

James Huenergardt · November 6th, 2007, 10:46 AM

Just wondering if the folks at Cineform are aware of this device:
http://www.dvinfo.net/conf/showthread.php?t=106861

I believe they are using a Sony MPG2 encoder for Long GOP and I-Frame encoding of an SDI stream to compact flash media.

It looks like a pretty neat device and I was wondering if Prospect HD would work as is with their files or if Cineform would have to tweak it?

Also, the XDCam EX and this device use FAT32 which has a 32gig file limit. Would it be possible to have an option in HDLink to use two files and create one?

Thanks,

Jim

Not only are we aware of it, we would like to compete with it. We looking of the right partners to produce a ultra-mobile CineForm DDR. Why record to 160Mbs 8-bit MPEG when you can do 10-bit CineForm with higher quality at a lower bit-rate? We also intend to include pulldown removal, 180 degree flip control, MOV or AVI recording, etc. Care to pre-order?

Count me in! I would LOVE something like that.

Especially since I've heard that the SDI on the Sony XDCam EX is true 10 bit. That would be a WONDERFUL device.

Yes, oh god would I ever. Need Beta testers? ;)

Right there with you David!

Christopher Barry · November 6th, 2007, 02:52 PM

Sure David, I'd likely pre-order, once you provide a few more dots to connect, in due course.

Jeremy Kromberg · November 8th, 2007, 07:38 PM

I would buy one for sure!

Anton Galimzyanov · November 9th, 2007, 04:45 AM

Me too! The main reason is because though Wafian is a great product, it is 'a bit' overpriced.
We all need a true working solution, David )

Guys, thank you for stating your interest in this potential recorder device. This is a very interesting project for us, and as David Newman stated earlier we're now working on putting the partners together to make it happen. We may offer you early entry in some form still to be determined.

If you have comments or suggestions, don't hesitate to throw them our way.

Dumb question, would this device capture both audio and video on the Canon XL H1?

Best,
Christopher

David Taylor · November 9th, 2007, 04:39 PM

Certainly not dumb - YES!

Chris Hurd · November 9th, 2007, 05:01 PM

Meaning it'll have RCA audio inputs, as that is the only way to get uncompressed audio out since audio is not carried over SDI on the XL H1 is it is on all other SDI-equipped camcorders. Mentioned just to clarify things for those who might not be familiar with the XL H1. Thanks David!

David Taylor · November 9th, 2007, 05:11 PM

I hate to expose ourselves too much yet, but we imagine different versions of the recorder. One of earliest versions would support HDMI for input as that is a growing trend on HDV camcorders, and the HDMI output is pre-compression.

We imagine HD-SDI as a different input module, and probably a different part number, but certainly one of the products in the family.

What do you think? Should we have an open-RED-style discussion about this?

Carl Middleton · November 9th, 2007, 05:44 PM

I for one would love an open discussion! If for no other reason than how different many of your customer's gear, setup and workflow are. You don't have to give away too much, but I'm sure there's plenty of people with 2 cents to throw in. :)

I shoot with a Z1, and I guess the best way to capture from that would be component+RCA... I personally would really like to see some way to capture D2D using my Z and hopefully allowing 2 conversions - 4.1% slowdown + force progressive would be wonderful.

That would allow a direct to disk 23.97p capture from a 50i or 25p camcorder, a lovely ability if feasible.

As well, I think solid state would be a big plus... prices are dropping and it allows a much smaller size to weight ratio and more portability for adventure video types.

Are the mini DDRs going to have hard drive or compact flash for there recording? This is very exciting!!!
