  • Is anyone shooting Prores in 4.6K resolution?

    So first, I'm understanding this correct, right? With OS 4.0 you can record prores in 4.6K correct?

    "Added additional ProRes resolutions for URSA Mini 4.6K including 4.6K 16:9, 4.6K 2.4:1, 4K 16:9, 4K DCI, 3K Anamorphic, 2K 16:9 and 2K DCI."

    I haven't seen even 1 comment about this, and yet I thought this was one of the coolest and greatest additions. So, is anyone using this? I know I would be. And to my knowledge, this is the first camera ever to offer prores above 4k. Or at least I've never heard of it. The Kinefinity Terra was going to offer 5k, but that never materialized.

    Also, what is the data rate of Prores HQ at 4.6K?

    It's there, but I thought the frame rate was limited to 40fps (if I remember correctly). I'll check later today.

    Edit: yes, I was right:

    25fps = 15 minutes on a 128gb card
    40fps (max) = 9 minutes on a 128gb card

      Thanks for the info. Pretty much what I needed to know.

        If I purchased this camera I would more than likely be shooting ProRes 2k 4444 90% of the time.

        Unless you're doing something FX heavy or you know you're going for theatrical release (or Netflix) I find very little reason to eat up that much memory. Unless your shooting/post set up can accommodate that much space.

          I've shot in ProRes 4.6k once and it turned out really well, esp. given that it was a guerilla style shoot that took place in a restaurant with zero time for lighting setups. Definitely not my preferred way to work but it was sort of a last minute situation for the client.

          Footage turned out great. I want to sit down soon and run some tests on my UM46 to compare, but I could see myself shooting in ProRes a lot.

            I shot ProRes 4.6k a couple weeks ago on a doc sit-down interview, just for the hell of it. Had the 4.6 wide and a BMCC for the CU. Both look great, pretty easy to match. I did 3 ~45 min interviews though, ended the weekend with about 1TB of footage. It's not practical (for doc. For narrative, knock ourselves out.)

              Like Sarlacc, i shoot ProRes 444 XQ 2K either in a window or downscaled in camera from 4.6 K. Shoot about a TB or two per month depending on the schedule of course.

                Wish they would have given us 2.5k prores on the BMCC since clearly they can do 4.6k. *Wishful thinking*

                    In 4k at least, I've seen little, to absolute no difference in file sizes between RAW and ProRes 4444

                      Uncompressed, 3:1, or 4:1? That seems strange.

                        huge difference when shooting 2k or 1080.
