EPIC 12 and 16 bit RAW

[Andrae Palmer]

Noticed that the EPIC is listed as both 12 and 16 bit RAW... when is it 12 and when is it 16?

it's interesting how many many times i read threads talking about this and never get to read an aster from red ... everybody are saying that is 16 bit , but i honestly never read any official word from red ....

I have tried a few times to get an answer to this, and have not been able to get an answer from Red.

So.......perhaps, internally the system is actually less than 16 bit, but in Redcine-X it can output at 16 bit.

 

[Gabriele Turchi]

at this point i really think that epic raw is not 16 bit ... too many times this has been discussed and no one from red said that is 16 ...

hope that they can step in in this thread ..

the wrapper (redcode) should be 16 bit. but the A/D conversion is a different story. no clear answer.

 

[Louis Maddalena]

Its 16 bit.

This info is still too ambiguous for me.

 

[Yaque Silva-Doyle]

I was under the impression that it was def 16 bit.

 

[Jarred Land]

It's rather complicated, but all that is important is that in camera it is indeed 16 bit, and RCX pro is 16 bit+ . Rob ( if he is listening ) can explain the "+" part .

 

[Rob Lohman]

RCX (and SDK) does processing at 16-bit and 32-bit float where needed

Thank you! This is great info.

So when is the camera in 12bit mode, or is it ever in a 12bit mode?

Also, is the stills mode identical in bit depth to the motion mode?

 

[Rob Lohman]

Martin: please re-read what Jarred wrote. As of right now there's no stills mode, when that is implemented we can talk about any differences, if there are any

 

[Per Kreuger]

So, does tat apply to Scarlet as well?

Yes

My confusion over this is that your website spec page mentions 12bit, as in....

"REDCODE™ 12 and 16-bit RAW : Compression choices of 18:1 to 3:1"

And so hence my persistence about what the 12 bit means.

 

[Rob Lohman]

Martin: Jarred is clarifying that you should only concern yourself with the 16-bit number. Forget about 12-bit.

Okay....will do.

is the "+" floating point?

 

[Rob Lohman]

16+ means 16-bit and up (32-bit is more)

Then the information on the website that lists the specs and features of the camera should be changed. One of the factors (a minor one, but a factor) in my decision to buy Epic instead of Scarlet was that I thought I was getting a CHOICE of 12 or 16 bit files. I figured that on jobs where minimizing file size/maximizing recording time on an SSD module was paramount, I could use 12 bit mode. Perhaps my lack of study of the whole RAW shooting thing has me misunderstanding what's even at stake, but the "normal" implication is that you'd have a choice affecting file size in a tradeoff with sampling depth/file size.
