RED party reel powered by RED RAY

You guys have validated my faith time and again, but I will not believe this until I get proof of that data rate.

Quoted for truth.

They showed an uncompressed 4k reel and a 10mbit/s RED RAY reel back to back and I simply could not see a difference.

I *think* Ted said the uncompressed reel was 400mbit/s.

 

[Roberto Lequeux]

Yes... more, please we need more people saying things like this :crossing fingers:

 

[Jamon Lewis]

.... the truly amazing fact Ted ws passing along is the average data rate for RED RAY 4K @ 24 fps is only 10 Mbit/sec.

you cant be serious... bits not bites????????

 

[Roberto Lequeux]

you cant be serious... bits not bites????????

that is what they are saying...

 

[Peter Mosiman]

someone explain what this means pleaseeee... i'm lost. (sorry for being a noob)

 

[S. Um]

I think Red Ray uses wavelet compression, which is a lot more efficient than the discreet cosine transform (DCT) compression used in MPEG.

 

[Tanner Field]

Hey Peter... I'm a bit lost too haha, but I think the basic idea is that somehow the RED ray is outputting 4k at 10 mb/s... a comparrison would be what we talked about in class tonight with XDCAM outputting at 35mb/s... so this would be several times the resolution at a third the bitrate... am i way off here???

 

[Roberto Lequeux]

4k at a size smaller than standard def DV

No, that would be a pretty accurate summary.

Or as Ted said "less than half the bit rate of standard definition mini-DV"

 

[Justin O'Neill]

A standard def DVD is usually around 5-8mb/s. RED Ray is outputting 4k at just a slightly higher data rate.

 

[Paul Lee]

Bad ass.

 

[Chuck Z]

Okay, now I really need a visual demonstration.

Wholly smoke! Do you know the significance of this?! Well, I guess you do :sifone:

Seriously, it is technically possible because, at higher resolutions, the compression is more efficient. The quality does not scale linear to pixel count. Additionally, wavelet compression is much more efficient than MPEG-2 that Sony was champoionning for the last 20 years and holds about 150 related patents dragging the whole industry backwards two decades. Besides, the Blue Ray, is also based on the obsoleted MPEG-2 so that Sony could collect royalties....

Anyway, very impressive result. :thumbsup:

Pawel are you there? Did you see it?

Pawel are you there? Did you see it?

No, I wish I could. But, I can believe the results

Have you seen the link to the live stream? It was posted in another thread...

Keep an eye on this for later...

thanks for the link... watching now!
Image ain't so great and keeps freezing, but at least the audio is coming through...

RED RAY data rates

RED RAY data rates

We need to hear "3rd party" opinions on how it looks

About to run the uncompressed (~ 800MB/s) and RED RAY (~ 10Mb/s) reels one more time...

1 MB = 8 Mb

 

[Roberto Lequeux]

Yea, but get people to post too.

 

[Chris Swinbanks]

almost as much fun trying to make sense of the "chat".....
