  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

REDRAY Comments

Don't expect BD quality out of 20Mbits 4K encodes- REDCODEC is not more efficient than AVC and Blu-rays are encoded with 20-35Mbit for HD res using encoders designed for this, with tweaked segment encodes over 2 or more passes. Relatively it will be way <BD quality- there is no magic and as much as RED can do good encodes out of their encoder you can't win with math :)

First of all this is a REAL NAME forum for real men and women to voice their opinions. When you hide behind a fake name and spew nonsense the response for the rest of our community is simple...

Please inform me- happy to hear all great things :)

Andrew, I have seen 1.5 MB per second RED Ray 4k projection with my own eyes and I promise you it blows Blu-ray out of the water. RED has shown this to thousands of people and every single one of them has been blown away. It seems impossible, but they have pulled it off.

Just curious - why this exciting player device called "REDRAY"?

Additionally to Bob's point. You'll be able to connect REDRAY to not just projectors, but also 4K televisions/monitors. REDRAY is a 4K playback device with online and local media capability.

REDRAY will be built into at least the CRIMSON projector as well.
 
It sure is nice being the little guy...

Stuart English has said REDRAY will be built into both projectors:

This unit is the standalone player and can be used in a wide variety of applications. In addition there are two laser projection systems - REDRAY Projector (consumer) and CRIMSON (theatrical); both of which include the same REDRAY 4K 3D engine, that will be formally introduced later.

next step up from Blu-ray.

LOL I think that in every CD/DVD player was red ray and blue was choosed just because it can read from two layers in single medium. Just some optic stuff.

But who cares, now everybody is thinking they have LED TVs and not only LCDs with LED underlit... whatever. :D
 
How long has Odemax been around? I see a trademark from May 06, 2008
 
1.5MB/s looked flawless. I wasn't looking for artifacts but neither I nor anyone else in the room lifted their hand to say they saw anything while gawking at the 40ft screen in RED Studios Hollywood. And that was like 2 years ago or something... 2.5MB/s would have been easy for their 2 year old codec.

Either that or RED is astronomically lying through their rotten teeth and hoping we won't notice the files are 10 times bigger... SCAAAM!!!

I mean, what part of shut up till you've seen it don't people understand?

I think it's fair to say that compression has come a long way in the last 10 years. I would be curious how long it takes to encode a 2-hour uncompressed movie through RedRay to create the .RED files. And I also wonder how compressing a movie 5 times more than the current Blu-ray specs will look in terms of artifacts. Blu-ray can theoretically go up to 45Mbps in terms of bitrate, but rarely go quite that high; broadcast HDTV typically goes no more than 20Mbps, and it looks fine to my eye, assuming good mastering.

It would be a miracle to see a 4K movie compressed to under 100GB, but I'd love to be surprised. It'd be interesting to see if known "torture test" compression signals could be put through the RedRay process to see how well they hold up. I know of some Blu-ray signals that are notorious for revealing certain kinds of flaws, some of which generally have to be tweaked by hand in the compression & authoring process. And I also remember vividly how the early VC1 and MPEG2 compression passes typically took more than 24 hours to do, when Blu-ray first came out in 2006. But that was a long time ago, technologically speaking.

Are you talking about quality represented by this clip:

http://red.cachefly.net/Tattoo2K.mp4

is this what you describe amazing?

Wow.. what a goofball. Your posts were for the most part wrong and i love that you use wikipedia for your facts but that last line took the cake.

Yeah.. a clip that was compressed with H.264 for the web is exactly what we are doing for... you got us. We developed our own custom compression ASIC for REDRAY just to fuck with you guys.. it doesn't really do anything.. really we are just exporting .mp4 clips out of quicktime player and renaming them to .RED.

My o my if you are really a professional "compressionist" I would hate to be one of your customers.
 
Any news of a REDRay demo in the Lodon area, say at the Pinewood RED location? I think I've read every post, but easy to miss one.

Was looking at making a trip there before finalising a Scarlet order I'm looking to make, so combining the trip would be great.
 
Jarred, any idea of the release timeframe for the projectors, getting the Redray standalone player and watching 4K movies on 1080p LCDs is a little bit a shame...

I started and found that 2.5MB refers to .RED format, so I removed wrong (assumed) info.

Lets ask RED team- what are the typical PSNR values for new 20Mbits codec?
Click to expand...

You forgot to remove your incorrect posts #778, 779, 781, 783, 784, and 788. What is being discussed here for REDRAY, is NOT the existing 42MB wavelet-based editing Redcode( .R3D) codec used in camera. So your posts about those don't apply here.

We are discussing the 2.5MB Redray distribution codec(.RED), of which we don't have any internals of the design. Many of us, myself included, have seen the codec in action with 4K material on 20-40 foot screens. And I can tell you, it not only competes well with H.264 at BluRay bit rates, it appears to vastly exceed them even at it's much lower bit rate...

Extrapolating your past experience with a technology that may be vastly different may not give you meaningful results.

Yes, they can be reasonably good for HDTV viewing at those rates, but that quality is not even close to what's needed for a 40 ft screen.

Prepare to be surprised... at 2.5MB/s its less than 10GB per hour for 4K .RED footage, approx 20% of your 100GB.
