    The focus peaking on the iPhone App Base on the creapy live Stream
    I use on my e1 the Lilliput A7s with focus peaking on 4k use the focus Assistent
    The live vew zooms on focus Assistent In ! and give 1 to1 pixel vew on 1080p A7 in peaking

  • Bob_HawkBob_Hawk

    24p it's nothing the framerate komm from Monitor on Auto

    The Video out on the E1 it's Max 1080p on 4k its only 1080P

    You can Record 4k 25 and Monitor 1080p 50

    Still have one problem. HDMI out is always 25p, 50p, 30p or 60p. But what if I want 24p??

    @Vitaliy_Kiselev, is it possible to view files on E1?

  • Vitaliy_KiselevVitaliy_Kiselev

    @storyboardcreativity

    You can try to put some video files (used to check 444) on card and connect camera to monitor to check.

  • storyboardcreativitystoryboardcreativity

    @samuelcabral, I'm not sure about it. Data is packed as 4:4:4 but it can be 4:2:2 from DSP. We need somebody to test it because my recorder can only write 4:2:2 to SSD

  • samuelcabralsamuelcabral

    Great! This means that i can get 444 with an external recorder?

  • storyboardcreativitystoryboardcreativity

    GUYS!!! GREEN SCREEN IS TOTALLY FIXED! Blackmagic Shuttle 2 wants YUV 4:4:4 signal out from camera's HDMI, but in E1 it's forced to RGB. I've made it to use YUV 4:4:4 through HDMI - result you can see in pictures below. Some little things left, like make sure it's real 10-bit color. I'll upload fix to my repository: http://github.com/storyboardcreativity/Z-Camera-E1-Reverse-Engineering

    Today got Blackmagic HyperDesk Shuttle 2 and... it's a fail. Green screen. Any ideas?

    I need some help from E1 users. Do you have any problems with HDMI out? On my 0.31 version I have frozen picture on LCD when HDMI is connected and after some idle time HDMI out signal is frozen too. Is it ok? :D

    It had been some discussion here https://www.personal-view.com/talks/discussion/18293/z-camera-e1-mini-m43-4k-camera-for-199-only-cheapest-4k-ever/p6

    @ Vitaliy_Kiselev

    I see! Thank you.

    Do you know the statistics for the HDMI out? Is it 10bit from the sensor or 8bit from the chip? Could I use a 4:2:2 external recorder?

    Sorry for the silly question.

  • Vitaliy_KiselevVitaliy_Kiselev

    @BerryJP

    Camera does not compress HDMI signal (except may be for color sampling) :-)

  • BerryJPBerryJP

    Hi! New here. Thank you so much for this!!

    Can anyone tell me if this affects the HDMI output at all?

    I use my E1 connected to a capture card on my PC so higher bitrate HDMI out would be amazing!

  • markr041markr041

    This is the actual resolution of the Sony RX100 VI when it shoots 240 fps that is nominally 1080P: "240fps/250fps (1,824x1,026) ." Close, but not there. (480fps/500fps (1,824x616)). So, they all cheat, although Sony makes its real specs available.

    @rjhinde, I wrote a letter to Z Cam with some questions about slow motion on E1. It will be better if it's possible to read only top sensor part (still 1536x288, but without subsampling). It can make quality much better.

  • rjhinderjhinde
    "720P 240 FPS" mode, actual readout from sensor is 1536x288! Than frame is interpolated to 1280x720 and encoded.

    No wonder it looks so bad, thanks for the info - little point in bothering with 240fps on that camera :-(

  • Bob_HawkBob_Hawk

    I got my E1 with the Izugar Fw 0.28   after the update to the then official 0.29 fw a few features disappeared company policy?

  • Bob_HawkBob_Hawk

    The sensor has extra a 3x3 readout mode?

  • storyboardcreativitystoryboardcreativity

    Hey, guys! New info about E1 firmware internals: when you choose "720P 240 FPS" mode, actual readout from sensor is 1536x288! Than frame is interpolated to 1280x720 and encoded. So, it looks like a foul play from Z Cam :)

  • storyboardcreativitystoryboardcreativity

    @Vitaliy_Kiselev, what about DSP assertion codes?

  • eatstoomuchjameatstoomuchjam

    I actually looked around the older firmware before encryption and couldn't find anything resembling a key (which is not to say it doesn't exist). It may actually be in a part of the camera not changed by firmware (which would mean breaking it would be pretty much permanent).

    If it's just spelunking for features, though, I am already able to do that without breaking the firmware. There's another backdoor in. Is there one in particular that you're interested in?

  • Vitaliy_KiselevVitaliy_Kiselev

    The newer ones use zip encryption - so it's not entirely unbreakable, but much more time-consuming if you care to do it.

    Well, due to incremental nature of firmware it is easy breakable :-) As you can just use older, latest firmware before encryption to find proper keys.

    I haven't seen any reason to mess with it, though, since the current quality/features are already fine.

    Usually such things have few small surprises :-) May be some stuff stuff can be just disabled.

  • eatstoomuchjameatstoomuchjam

    If you can find an older E2 firmware package, they didn't bother with any sort of encryption. You can just unzip it and look around. The newer ones use zip encryption - so it's not entirely unbreakable, but much more time-consuming if you care to do it.

    The E2 firmware is mostly just a ucLinux OS. The camera-specific stuff (mostly) is in a single executable file. I haven't seen any reason to mess with it, though, since the current quality/features are already fine.

  • storyboardcreativitystoryboardcreativity

    @Vitaliy_Kiselev, I still don't have a E2. I started reverse-engineering E1 firmware because I wanted this camera and I saw that 4K24P 60 Mb/s is too low for this camera. It was just interesting for me. But I don't have E2 because it's too expensive for me - maybe later, when I can buy it with ~$400-$600...

    And what do you need to edit in E2 firmware? Is not it good?
