  • 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 :)

Are we fast enough for REDCODE 250?

I am trying to do a rough estimation about the total cost of the RED ONE to EPIC-X upgrade and was wondering if the RED DRIVE and RED RAM are fast enough for REDCODE 250.

A jump from REDCODE 36 to 250 sounds huge, although i am not sure it is representing actual bitrates...

What do you guys think? Will we able to record REDCODE 250 on our existing drives or are we going to need something like an EPIC DRIVE to do so? With the RED RAM around $4500 i wonder how much would that cost!
 
theres no way you'll get 250 MB/sec on those drives....

our existing drives could possibly get up to 120 MB/sec...if that

250 will require solid state or something different....
2 velociraptors would not get 250....

I personally will be using lower bitrates if possible....36 seems ok for now so surely 80 or so MB/s would be a step up...I don't see the need for 250 until we start talking high speed or high rez
 
Well either Jim or Jarred I don't remember which confirmed that the 'Redcode xxx' names on the new cameras are not actual bitrates just relative comparisons.

However, as for '36 MB/s' seems ok for now,' keep in mind that 100 5K frames compressed to 36 MB won't look nearly as good as 30 4K frames compressed to 36 MB do.
 
I also wonder if the compression for REDRAY is a taste of the goodies to come.
 
Keep in mind that the REDRAY compression is for mastered and already graded footage. Probably if you tried to mess with that footage in ways someone would mess with REDRAW you would see a lot of nasty things.

Does anyone have an idea what's the bitrate of REDCODE36? Maybe we could find out what is needed for REDCODE 250.
 
If the 250 in REDCODE 250 is just an analogy for quality and not actual bitrate then let's hypothetically say that REDCODE 250 is something like 128MB/s. What would a drive that could sustain such a write speed and be portable enough to be on camera cost?
 
I've set up a little package sized just as big as the RED Drive and it contains two Memoright 128GB SSD drives in RAID so I get a total of 230 effective GB and an average sustained transfer rate of 220MB/s (+/- 5MB) when connected via esata which is pretty much the maximum the protocol can support. The enclosure is powered by USB.

The esata enclosure cost me 100$, the expresscard esata controller 230$ and each of the memoright 128GB SSDs cost me 1000 euros (1300$)
So that is a sum of 2700$ (+230$ for the controller) for 230GB of portable RAID 0 striped backup storage.
 
Whatever speeds RED claims for data capture, they will have to use todays storage technology to store the data the camera is producing. As far as I know, the RED drive and RED RAM drives are about the fastest you can get and still be portable.
 
Unfortunately RED.com doesn't have any data rate specs for the RED RAM.

If it was certain that the RED RAM would be fast enough for REDCODE 250 maybe it would be wise to purchase one now that it's available before everybody starts looking for one after the Epic-X is released! :laugh:
 
Lots of renders have a dual card slot for CF cards, and even SSD cards if i remember.

Maybe the solution for high speed capture is 2 or more CF cards in a RAID 0, which would be merged with a program like R3d Data Manager.

That would get us a top speed of about 100MB/sec, based on current specs, and if the new system has a bigger buffer, we could use the 666x cards who's write speed fluctuates too much for the R1, but averages at something 'round 400x

I know this sounds crazy, but the maximum bitrate for RedCode36 is...36MB/s.

Actually it's just a bit more than that once you include overhead for the audio. :beer: Also the designations are based off of 24fps 4K. So shooting any other format will result in different data rates.

As for the discussion on REDCODE 250... It has been said in the past that the new REDCODE numbers announced were not referencing specific data rates. However, RED has not told us what the numbers mean, but that it would make sense when the time comes. So for now, it seems that REDCODE 250 does not imply 250MB/s
 
Plan on $10,000 a drive and you won't be disappointed. Honestly, if am thinking that to go from a well accessorized RED One to an Epic X will be about 20-30k. I hope that whatever RED decides that they keep the same shell for the drives, or at least publish the new dimensions, because I don't want to invest in the ET Shockmounts at this point until I know that they'll be useful on Epic.
