RedMag Record Times: 64GB / 128GB / 256GB + HDRx™™

[Ryan E. Walters]

As I have been planning for when my Epic-X arrive (Which I am EAGERLY anticipating BTW) I have found myself running the numbers for the storage, and run times for the RedMags over and over. So instead of doing the same thing over again, I put together these charts for reference and I thought that others might benefit from them as well. From what I have read so far, with the Epic-M's the run times for the 128GB RedMag have been close to what has been published, so extrapolating those numbers out, I arrived at these numbers.

Caveat Emptor: All things with Red are subject to change. These charts are meant for general help in planning for the Epic.

Enjoy!

Oh, and here is a PDF of the same:

Thanks for the info Ryan. It's makes me wonder which compression rate would work best for me.

 

[Roberto Lequeux]

Very cool of you Ryan, thank you for the numbers.

Now we need the same in terms of file size, if you feel like having a bit more Excel fun today.

Great Idea- here it is:

Awesome, Ryan. Thanks.

It's very worthy of a sticky.

 

[Elsie N]

Very helpful Ryan. Thanks.

 

[Roberto Lequeux]

Thanks again Ryan! Off of those numbers I am getting 31.7hs of HDRx 5k WS 5:1, and 63.4hs of non-HDRx 5k WS 5:1 footage in one 16-bay 1.5GB RAID with two drives "lost" in to parity in a RAID-6 setup, and calculating the space actually available due to formatting at 80%. Can someone more familiar with RAID setups corroborate?

 

[Ryan E. Walters]

Awesome, Ryan. Thanks.

Sorry about that- link fixed.

File size is way up from red one no?

I think 7:1 is going to be the best compression rate.

 

[Roberto Lequeux]

Right now I would bet alongside you Shawn. With 4.5k being enough for 4k resolved, that means that 5k has some extra room to spare. And if 5:1 is the gold standard with virtually no compromise, then 7:1 definitely sounds like a good place to be. It will come down to each running their own tests of course, but it won't be far from 7:1, and perhaps even a tad lower.

It is so nice and such a relief to know that this beast of a camera comes armed with REDCODE.

I think 7:1 is going to be the best compression rate.

Now that compression is measured in ratio, which is great, does anyone know what Redcode 36 represents?

Would like to get a benchmark compared to what I know.

 

[Lee Saxon]

Because of differences in spare area / addressable space on different sized SSDs I doubt the recording times will be EXACTLY 50% and 200% of the published 128 numbers.

I also bet there's additional metadata related to the co-mingling of the two streams that makes HDRx files a touch more than EXACTLY double the size (half the recording time) of non-HDRx.

I would still think these charts would be close enough to be useful though, just nerding out on you a bit

Hense the big bold word saying "Approximate" at the top of the charts.

If I'm not mistaken, RC28 is approx 10:1, therefore RC36 is around 7.7:1

I thought 7:1 was RC42?

FYI I recorded 8GB worth of footage including some timelapse stuff on one of my 64GB SSD's and it offloaded via FW800 from the REDMAG in 90 seconds. That is HUGE (16 GB CF cards were taking me about 6 1/2 minutes using a Rocketfish USB reader).

I was also able to playback directly from the SSD attached via the FW800 and open in RC-X, and was able to sustain RT playback at 1/4 resolution with no issue.

offload times

offload times

Thanks for that Jeremy.
That was gonna be my next question.
Does anyone else have SSD offload times using R3D DM?

Thanks

 

[Jeremy Torrie]

FYI we recorded 5K 2:1 aspect at 8:1 compression on 128 GB SSD and had 40 minutes of record time.

When we shot HDRx it was cut in half...really awesome feature -we literally could not have shot what we did without it given our small light package.

 

[Justin Marx]

I wonder what they are shooting on spiderman and the hobbit?

 

[Michael Kromschroeder]

How many minutes of footage do I get on to a 128 GB SSD when recoording 300 fps at 7:1 ?
