RED Storage Calculator

[Ed Watkins]

Here are some updated data rates for build 16.
They are an average of three tests: out of focus, sharp focus, lens cap on
Each test was approx 60 secs, @24fps
(I used the frame count from Red alert for the data rate calculation)
The average file size shown is in GB for 60 secs.

These are estimates (which I am using in my iPhone app), bear in mind the codec varies allot.

edit:
sorry my bad, last attachment was build 15 results, build 16 now attached

Is there an update for the widget that uses these data rates?

Thanks for the PDF file & calculator website!

Hi,

I would like to understand how to calculate the storage needed for the Red.
I would like to know precisely how you calculate it from the different variables:

- format (2/3/4K)
- Ratio (16/9, 2:1)
- RedCode (18/36MB/s
- frame rate

For me,
Storage (Go) = 28 (or 36) x SECONDS
exemple: 28 x 3600 = 100 Go / hour

I simply do that, but i would like to be more precise (with the ratio and the three formats). Can you help me?
Thank you.
Julien

Can you correct me if it is wrong?

4K, 16/9:

>4096 x 2048 x 12 = 100Mbits = 12MB

At 25fps:
12MB x 25fps = 314MB/s
This is for uncompressed 4K.

REDCODE 28MB/s means a 12:1 compressed and 36MB/s means 9:1 compressed, is that true?

Thanks.
