    Tom, is that HDRx™?

    Tom and Jannard, does Tom's Epic have 120fps enabled?

    Jannard, does the team know what will be the max framerate for HDRx™?
    120fps is enabled now... 5K 2.4:1. 96fps for 2:1 and full frame.

    HDRx max is half max for any given aspect ratio.

    This is really interesting - and great to hear that 120fps is available.

    I'm particularly interested to hear about any tests that people do screening footage shot 5K/24fps and then 5k/48+fps to see what truth there lies in the argument not only for spatial resolution, but also for temporal resolution. Tom, I'd love to hear more of your thoughts here, as you seem particularly interested (and perhaps, your subjects particularly well suited) to higher fps usage and testing the ideas of temporal resolution.

    Fortunately, I think RED has both fronts covered.

    Thank you Jannard.

    Have you considered measuring out what will be the lowest resolutions out of which Epic will provide 4k and 2k resolved detail, and making those two of the resolutions available in the menu so as to have a quick guide to get the highest framerate possible with little compromise for 4k and 2k projects?

    We took one final trip down to Salton Sea this evening with the Epic. It was heavenly. I think I have enough footage now to put a little video together, hopefully.

    Great question Roberto
    Can we dial in any desirable window size/compression on Epic?
    I guess to get clean 2k after debayer, one would need a 2.4k capture.

    Thank you

    Lots of custom options... just not now.

    Sorry, but that sounds a bit, well, silly -- shooting at 2.4K just so that you could nail a theoretically exact measurable 2K resolution??? (Which to avoid aliasing, would theoretically have to be kept in a final 4K container rather than a 2K container.)

    If you want a good 2K image, then shoot anything higher than 2K, like 3K, 4K, or 5K. Who shoots a movie so that every shot hits some perfect line resolution measurement? There are all sorts of real world factors that are going to affect measurable resolution shot by shot, we don't make movies starring line resolution charts.

    And why would you want to shoot at the bare minimum resolution above 2K to achieve 2K? What's wrong with 3K, for example? Why does it have to be 2.4K?

    This is where I think people are putting way too much emphasis on numbers. What happens when you achieve this perfect measurable 2K resolution? Do you get a gold star? Do you throw out the image if it ends up at 1.9 or 2.1?

    I think the logic is to be able to pick your frame rate, then choose the highest possible resolution that would allow it.

    I actually asked for something along these lines a long time ago by requesting a true 2.40 aspect ratio at various resolutions. Right now we get 2.40 at 4.5K, but I would like it at 4K, 3K, and 2K. If we could also get something along the lines of a Redcode 20 compression, I was hoping that these two options together might allow higher frame rates on the RED One. I would love, for example, to be able to shoot 3K / 2.40 / RC20 / 75fps.
