Scarlet connection, and RED 4K data rate
on Feb 3, 2010 at 4:35:32 am

Hi -
I read this, and I am probably wrong, but using Google, I can't seem to confirm any of this information.

1) will the Scarlet have an ethernet connection to allow off loading of the data, right from the camera ?

2) is RedRay now called Red4K (I am sure I have this wrong).

3) is the new Red4K codec 15Mb/sec ?

4) is there somewhere on the http://www.red.com website I can find info like this without having to plow thru reduser.net ?

Thanks -
Bob Zelin

You know, reduser.net is a good enough reason for me to prefer SI2K.

Scarlet is expected to have some sort of serial ethernet but it's also compact flash so I can't see using this for downloading unless it's an emergency and you don't have a $20 CF card reader handy.

Haven't heard anything about RedRay changing its name- or any sort of release date either- seems to have been back burnered for the foreseeable future since it was announced a few NABs ago.

As for the data rates I haven't heard of any going that low- it's 28, 36 and 42 as of the moment.

On Adam Wilts blog at ProVIdeo Coalition he says that the delivery codec developed by Red called RedRay has indeed changed its name to Red4k and at 24fps 4K resolution has a data rate of 15M/bits per second (with sound). There is post by Jim Jannard on reduser.net that confirms this here;

Only if you buy me a drink first. Seriously though, how is it even possible?

you mean how can they get a "lossless" compression of 4K down to 15Mb/sec ? It not only seems impossible to me, it seems impossible to people that I know who are actually SMART and understand this stuff really well. RED's ability to do this type of data compression is far more valuable than the RED camera itself. It would (and will) apply to all industries requiring hi speed data transfer across a limited bandwidth network, that rely on data compression for distribution (like cable TV companies). This is amazing.

Bob, REDRay has been renamed RED4k. The compression is neither lossless nor "lossless" - but it is 15megabits/s for 4k 24fps and looks way way better than it has any right to. We've done a few public demos of the codec, at the Vegas RED meet last year, and a couple of weeks back at the RED Studios Hollywood RED Day. I don't think anyone in the audience had any complaints on the image quality.
