  • Few things about my Pocket 4K...

    Hey all!

    So Iím VERY happy with the new pocket 4K. Itís everything I expected and more!

    A couple of dum dum questions, so what better place to ask!

    Can you do prores at 120fps? I couldnít seem to go past 60, but I switched to RAW and had the full spectrum.

    When I go into playback, how do I go back to my record screen? Iíve found I just press the record button, but sometimes that starts recording when I donít want it to. Is there an easier way that Iím stupidly missing?

    Thirdly, I have some dirty, rough, run n gun footage I shot with my mates taking a stroll to test the camera. Iím nervous about posting it.

    Anybody genuinely interested? Itís essentially the first shots I took with the camera. Lots of challenging lighting and pushed colour grading.

      Okay, keep an eye on my Vimeo page. Be gentle! Haha.

        .
        Yes, but only if you window (or crop) into the sensor. You get the full 120 fps in RAW because it automatically crops by default.

          I think you just have to press the playback button again to return to the recording screen.

            Doesn't work in my case. Pressing the record button brings you back to the regular interface.

              Of course! Agh I'm so stupid. So when I chose prores, it wouldn't go past 60 because I was using the down sampled 1080. Makes sense!

              Pressing the playback button only plays the media that you're on. So you press the menu button and it opens the menu. Pressing the menu button again, takes you back to playback mode. Pressing play in the menu, takes you to playback mode.

              There must be a simpler way without accidentally recording?

                Bmpcc and the BMMCC both use the record button to return.

                  Hmm. It’s something so small, but so annoying! Did you ever find yourself accidentally recording too?

                  During the time of shooting the video I’ve linked above, I had three instances where it accidentally recorded. It really isn’t a major issue, I just feel like it could be fixed so easily!

                  Never had problems on the BMCC!

                    It's lovely, Very nice showcase of what the camera can do with virtually nothing.

                      Thanks for that Alex!

                      I thought it’d be useful to see it in that context!

                      You really don’t need much to get some decent images out of the thing.
                      Can’t wait until more people get their hands on it!

                        I think instead of opening a new thread I'll just hijack yours, since I'm on the same boat: just received my p4k and have very similar thoughts and questions (e.g. the playback thing also got me, I spent a couple of minutes trying everything except the record button, duh).

                        I ended up getting a slow 256GB CFast card (the Transcend 600x) instead of a fast SD card (anything V90 and not too dubious was more expensive than that). It can do 4k 60fps 4:1 RAW (or as least it worked on my test, which was about one minute long).

                        Question: how does the flicker correction work? I told the camera I'm on a 50Hz country but setting 180ļ shutter doesn't addjust the shutter to the closest 50x multipliers, which means I have to switch from 172ļ for 24fps to 216ļ for 60fps. I'd like to have the camera automatically switching to these close-to-180ļ-but-without-flicker options by itself.

                          Great query Sam! Happy for you to chime in!

                          As you can see in my video, I had some trouble with the flicker from the sodium street lamps, would love to know if I could’ve solved it at the time?

                          I’ve still got a lot of testing to do. Coming from the original BMCC, I’m having to reprogram myself to expose differently. I don’t believe ETTR gets you the best image from this sensor. The highlights do act differently.

                          Would ETTL be the way to go?

                          I kind of love the highlights in this cam though. For me it feels like the different sensors are like different film stocks, and understanding how to shoot to get the most out of them is the fun part!

                            ETTR is generallyl a good idea with any camera shooting RAW. On this one you may have to leave a bit more room before you allow it to clip, though. I haven't tested myself yet, but there was a comparison with the alexa somewhere and well, it's nice but not Alexa-nice XD

                              Looking at the manual, it seems the 50Hz/60Hz setting only makes the camera suggest more appropriate shutter speeds, but won't change them on its own.

                              I would like the camera to somehow remember that when I shoot 24fps I want 172ļ (1/50s) shutter, and when I shoot 60fps I want 216ļ (1/100s) shutter (make that 1/60s and 1/120s if you're in a 60Hz country). But it seems I need to press three buttons in order to get this: first the HFR button, then the shutter button (because, even though I only use manual lenses, the wheel can't be mapped to automatically affect shutter speed), then the shutter adjustment.

                              Oh well, it's still better than on my old Sonys that required going to the awful main menu...
