New RedRay bitrate?

[Stuart English]

A small question about the sound. Red-ray will obviously propose multi-channels (let's say 7.1 and beyond).
At this time, a 7.1 DTS-MA often tops at 4.5Mbps. For a 2h movie, it's about 3500MO per soundtrack.

Finaly, the final film size will remain pretty big... no ?

Correct, up to 7.1 Channels on the consumer player. And up to 12 Channels on the pro version.

The final "movie" file size is quite small as the average RED RAY 4K data rate is only 20 Mbit /sec

Does it mean that the RED RAY 2k data rate is 5 Mbit/sec (or a bit more because of some "overhead")?

That is a really good question, but we'd prefer to consider what the possibilities are for 4K distribution.

1080p and 2K are the past.

4K resolution is the future.

I'm still having a hard time figuring out how the heck the RED guys have been able to package 24 frames of 4K into a 20 Mbit signal. That's 2.5 megabytes - or just over 100 KBytes per frame of 4K. Pretty amazing stuff!

Of course 4k is the future, no doubt. Even YouTube goes 4k and Apple will go retina on all devices. But sometimes you want send someone a 1k, 720p or 1080p preview in a global network.
How about software encoder initially up to 1080p as a plug-in in your browser, think YouTube, iTunes etc.

Stuart,

The current specs on the RED website say 4k can playback up to 25fps and 2k up to 48fps. Is this still the case? My question is will we be able to play back 3D 4k at 48 fps so that we can one day watch the Hobbit, and future 3D movies, at home in all its glory? If you can't answer today, understood.

[Jeremy Torrie]

What's truly incredible is we have internet access up here at 15Mbits/sec. We're not that far away.

Yes, but we can give you 1080p HD directly from either version of the player via an internal high quality downscaling engine. Your clients will thank you as the result is 1080p in a visual glory that no-one outside of a production studio or industry trade show has ever seen. It ain't 4K, but it is really good.

There is 8-bit 4:2:0 H.264 for that application - all the NLE systems have that as a standard function.

We do provide .MP4 file decode capability on both of the RED RAY players in addition to RED delivery codec decode. The former therefore allows you to read these 720p or 1080p 8-bit H.264 .MP4 files created for someone to play on their laptop or i-display, but the latter is the high performance proprietary codec that delivers all the visual goodness of a 4K 10-bit RGB source...

Comcast just launched 105 Mbps. http://www.comcast.com/About/PressRe...ashx?PRID=1067

Very nice. So your 120 minute long 4K resolution RED RAY movie will download in about half an hour...
