  • 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 :)

I have written a very basic RED Storage Calculator:

there is also an "on set explaining things to the DOP sheet" on the site

have fun!

thats damn handy, thanks!!
 
Nice Chart Alexander.

BTW, the chip sizes are a bit off.
For example, to calculate the sizes for a format on RED One:
4096 = 4096 * 5.4u = 22.118mm
2048 = 2048 * 5.4u = 11.059mm

Jon Farhat also posted a size diagram which should be
 
hi Deanan

i will fix it in the next version,

thanks

Is it possible to make a Widget for Mac OS X ?

That would be great !
 
Thanks!
Very useful. A vector pdf version of the chart will be perfect...

Just noticed the link (to the pdf file) at the bottom of the calculator page.
Thanks again.

most excellent ... thank you

most excellent ... thank you

Great widget, Aboerger .... very nicely done.

Quick question .... don't know why but I assumed that a 2:1 extraction would be bigger than 16:9 but according to your cool tool, 16:9 extraction is larger than 2:1 ... could you explain the math behind the calculation.

Thanks,
Neil

ok, cant resist:

here is the widget, but i think i will build a smaller version

4k 2:1 recorded image size is 4096 x 2048
4k 16:9 recorded image size is 4096 x 2304

But if you do a 16:9 extraction from a 2:1 recorded image you'll get 3640 x 2048, which may be where the confusion comes in.
 
awesome :) thanks for the widget
 
Codec data rate variability - how much?

Codec data rate variability - how much?

Just found this thread, very useful, thanks. BTW, the codec is variable bitrate, so I don't know what numbers he worked from.

Curious about how MUCH it varied, I did a little test shortly after I got my camera - I went and found a scene with the most high frequency detail I could - in the park by my house, with trees, gravel, leaves, etc.. Shot it as sharp as I could get it, then totally defocused, then with the lens cap on.

Here's how they varied:

....so you can see from the second to last column that they varied a LOT, as much as 35%.

I shot this with the Red 18-50 lens, so with, say, a Cooke S4, you could probably get even more detail, and hence possibly higher data rates, from the same scene.

This was all build 15 I think, I'm planning on reshooting a similar test with build 16 soon.

Also interesting to note was that the purportedly "all black" frames (with lens cap on) pretty much matched the high frequency scene - perhaps the codec was scrambling in the dark for any detail it could latch onto, like a tweaker sifting through carpet for that one...lost....pill?

Anyway, interesting stuff (to me).

Codec tweaker that I am.

EDIT - checking the release date of the builds, this was probably with a beta of build 15
