New RedRay bitrate?

[Steven Caesare]

Just listened to Ted's speech to the DCS Workshop (http://www.digitalcinemasociety.org/...hting Workshop ).

In it he speaks about RedRay briefly, and mentiones 20Mb as the bitarate for RedRay.

Previously it had been spoken about as 15Mb. Is the target now 20?

Interesting... Gearing up for NAB it seems....

[Jonathan Stevenson]

20 is still amazing.

Editorializing Ted's comments

"...we decided to add 20Mb/s as an encode option for 4K RED RAY when driving large cinema screens..."

and

"we challenge anyone to spot the difference v's DCP" :-)


For reference it's a 40ft wide screen at RED STUDIOS. And a data rate of 20 Mb/s is less than 10% of a 2K or 4K DCP.

Thanks for the clarification, Stuart. Amazing indeed.... can't wait to see it!

The redcode rgb thingy is the next big thing.

Really looking foreward to news about colorspace and signalchain when developing and grading for RR -> cinematic release.

Let us not forget broadcast please!

I would love nothing more than to have a RedRay recorder to generate masters to, and then downconvert to HD SR.

is it like the laser pointer 's red laser pointer.????

All true, of course. But I would also ask: Does it support FIPS compliant essence encryption and/or link encryption? Is the codec planned to be open sourced? Is the color space defined?

Standards are important and open standards are desirable in a technology driven industry that is constantly changing. That represents a large part of why the digital cinema package was developed and why it has been successful. It's great that new compression techniques can make for better high resolution images, but distribution and exhibition are ultimately businesses that require certain protections to be in place and certain standards to be met in order to ensure that the material will be properly prepared, delivered, and exhibited. I know what I'm saying is nothing new, and you've probably taken it into account, but for theatrical delivery systems to be accepted requires more than nice images and low data rates.

I trust RED did their homework regarding standards and encryption and DRM... but entering (and potentially disrupting that space) all starts with nicer images and better data rates.

FIPS compliance is not all that difficult when working with a lot less data to encrypt. Its more about enduring the bullshit bureaucracy and time wasting with government run agencies . I could be wrong, but i would wager THAT BS is the #1 reason why RED RAY has been delayed... since the nice images and frame rates have been working in beta form for over 2 years at Reduser Vegas 2009.
