Epic 2K 300FPS record time for 256 GB card

Evening Gents and ladies

Anyone care to enlighten me where I can figure out how long I can shoot 300FPS in 2K highest compression setting.

I tired extrapolating this

But it gave me a strange answer.

Basic math would be

276 minutes at 5K 2-1 5:1 at 24 fps

(24x300)/276=26 minutes of real time recording.

Is this right???

If you have an iPhone download KataData it's a great Red data calculator app. This is what I get: 17.1 minutes. That's at 7:1 compression which I believe is the maximum at 2K @ 300 frames per second.

128GB SSD, 2K WS @ 24FPS @ 8:1RC = ~300min
So based off that, 300FPS being 12.5x that of 24FPS....
128GB SSD, 2K WS @ 300FPS @ 8:1RC = ~24min

So you should get under 24min I believe.

On a test with a 64GB and 128GB card, black frame, 300FPS 2K WS, 7:1, recording ~1 minute gave me a R3D of 6.7GB, so on a 128GB card I would get roughly ~19minutes total.

Of course this is a Black Frame being recorded , in comparison a test with motion and detail, 1minute gave me roughly 6.9GB.

Hope this helps a little bit

a frame is a frame ...

I think the calculation in the sticky about record times shows 0.66Gb per min at 7:1 compression 2K and 24fps. that works out at 1440 frames = 0.66Gb
300 frames = 0.1375 Gb - that's 1 sec.
1 minute of that = 8.25Gb
so a 256 card should give you about 30 - 31 mins (all relative of course) at 7:1 in 2K
of course I could be missing something
