    Also data rates being a big one. But it probably won't be long before one of the VDSLR company brings out a psuedo-HDR mode for the new...whatever

    HDRx™ is recorded as two streams, so data rate is twice normal mode. Combining them happens in post and there are a wide variety of options for doing this. Again, you are limited to shooting maximum 5K at 48fps.

    How 'bout +12 stops (for a total of 25 stop DR) with four streams at maximum 5k 24fps?

    Going with the SSD no doubt, but with 24fps and 48fps HDR for just a little slow motion effect on Hair, and clothing movement and such, will the added data rate be allowed to be utilized the same way in the Red Rocket for the Mobile Rocket, or will two Red Rockets be needed and only possible with the Tower Configuration?

    Sorry if it was answered, didn't find it if it was ;)

    Yeah, but 5K 100 FPS is huge. It's the feature I look forward to the most.

    I agree with you Shawn
    If they share the same features then it's better & cheeper to get 2 Scarlet in place of one Epic (one for s35 and another 2/3 for slow motion)

Since it is very rare to need 18 stops, you can set different HDR settings... like +3 stops, +4 stops, etc.

    You are really going to love this. We are working with the Foundry for the HDRx™™ mode. Graeme and the Foundry boys make a powerful combination.

    Very cool! Coming into this late and only read the first 15-20 pages of posts, after reading this and based on double data rate and mention of the Foundry for motion blur issues, I'm guessing:

    -you guys are reading out twice without resetting the sensor back to "zero" state

    - one shorter exposure reading out first, generating shorter motion blur on the shadows but preserving highlight detail,

    -and a second "pass" that is longer but includes the first, with a brighter image, so the motion blur is longer on the highlights

    -thus would need to integrate the two using the motion vector temporal math that the Foundry offers, to make the motion blur consistent

    -the SDK method glues the two exposures together blending using HDR methods to get the highlight (edit, thinkin' backwards) detail from the first shorter readout but has potential motion blur inconsistencies between highlights and shadows

    So expose from zero to a fraction of the 1/48th or whatever you're shooting, read it out while still exposing (preferably), then read it out again for the full 1/48th exposure

    -therefore you're biasing the exposure a little on the hot/overexposed side, rather than balancing entirely, since highlight (edit, was thinkin' backwards) detail is coming from that first brief exposure period

    -otherwise you have temporal mismatch - gotta expose with as much overlap as possible rather than sequentially.

    To get the +3, then expose up to 3 stops overexposed?

    How am I doing so far?

    You will likely not ever need more. You will get it because we will make it. But EPIC is the ONE that changed everything. I have seen a lot. I own over 1000 cameras. EPIC is the one that will change history. It is the one that covers everything. Size, price,performance. If I died and went (somewhere)... I will be content. EPIC will get to market.

    You know I do see that, although I'd say we were already almost there with our Red MX - we are still getting used to thinking in terms of the latitude it gives us, and cutting down on light sizes when we rent - the other day I caught myself trying to figure out how we would cheat candlelight and realizing that would not at all be necessary. It is already more camera than we ever thought would exist, let alone that we would own.

    I see that with our 5D (in terms of STILLS). I really don't any longer feel the need for anything else in terms of full-frame 35 stills cam. I am happy. I don't read new stills cam announcements anymore. I don't care, I have what I need for that, I'm done.

    5k 18 stops in raw in a light package!? I'll buy an Epic and just keep it forever.

    Any comments on the 2K performance of the Epic? Same, better than MX?

    Mike, a shorter exposure would give you more detail in the highlights, not the shadows. As far as how RED is doing their magic, that, I can't answer.
