Hi everyone,

I'm sorry if I am re-posting an old topic, but I have scoured everywhere and have come up, for the most part, empty handed. What I am trying to do is calculate the amount of time I can get off different RED media dependent on resolution, frame size and compression. I know there are plenty of data calculators out there -- I have been messing with them -- but most of them only cover 4K and those that do cover 2K or 3K only do so with one aspect ratio. I want to be able to calculate the difference between 2K 2:1 and 2K 16:9, for example. I have pixel resolutions for these, but I am fairly confused when it comes to calculating all of this information together.

Is there a formula to calculate, based on pixel resolution and different REDCODE compressions, the amount of MB/s?

I am aware that REDCODE is a variable compression and so any calculations will be approximations. Thanks in advance for all of your help!

There are several apps for the iPhone out there to calculate those things. For example iSee4k or Pocket DIT.

Cheers
Thomas.
