    I hope they do it before 25th.

  • Btw how soon they start doing proper Android app? Matching iOS?

  • They aren't talking about Android at all.

    You can see empty place from damaged part near green dot, and lot of empty spaces originally present on board

  • For now do not see any updates still.

  • FW 0.31 is out.

    The FB page has a link to google drive. It's not on the official page ...yet? It would be best to wait until it's on the official page or join the FB page "ZCAM E1 Users"

    It is all so similar to Yi M1 one year ago. Up to the point where they assume Facebook being center of universe.

    And I guess it is last ever firmware update.

  • Hi! I'm thinking to buy a second hand Z-cam E1 for fast timelapse and maybe for a 360° photo rig. I didn't find the user manual.

    It seems photo timelapse is limited to 1s interval. But is it possible to shoot faster with external control ? Not burst mode with exposure locked, I need metering for each images. I'd like to take 2 or 3 pics per second.

    An accurate timestamp is useful when you want to geolocalize images with a gpx trace. But I don't know if this cam store the subsectimeoriginal exif value to complement the DateTimeOriginal.

    Could a E1 owner help me?

    Thank you in advance

  • Hey!

    I've been working on 0.31 E1 firmware for 1 week and got some results. Now I can shoot DCI 4K with ~80 Mbps. But I can't go higher because of very strange bug - when I set bitrate higher than 0x03E7FFFF, all become a mess and I don't know what is this. Can you give me any advice?

  • @storyboardcreativity

    Can be anything, from other parameters limiting normal work to hardware limits.

  • @Vitaliy_Kiselev

    E1 is based on Ambarella A9 - does it have hardware limits?? Maybe somebody has already done hacking bitrate on any other A9 camera? As I know, H264 is encoded in this SoC by hardware DSP. This bug seems not like overflow.

  • @storyboardcreativity

    Check Xiaoyi YI 4K Action Camera hacked firmwares.

  • @Vitaliy_Kiselev

    "Check Xiaoyi YI 4K Action Camera hacked firmwares" - checked a week ago, didn't help me.

    Good news! Just reached stable 100 Mbps in 24 fps 4096x2160. As bitrate is limited to 0x3E80000 (65536000 bits per second) by unknown magic, I switched mode in code from CBR to VBR and set min and max percents to do bitrate at 160% from average. Now I set bitrate to 0x3E7FFFF (65535999 bps) and get bitrate around ~104857598 bps (~100 Mbps).

    Higher percents make camera freeze in ~5-6 seconds after recording start (I think that because of SD card bus). Do you know any variants to overclock micro-sd? :D

  • Higher percents make camera freeze in ~5-6 seconds after recording start (I think that because of SD card bus). Do you know any variants to overclock micro-sd?

    No :-)

    But again, check all other Ambarella firmwares hacks, as controller is 100% same.

    It can be also your card.

    Also try to publish modified firmware and provide here link. Even for unfinished hacks.

  • @Vitaliy_Kiselev

    Also just reduced GOP size to 1 (now get Intra frames only). Works fine and stable.

  • @Vitaliy_Kiselev

    I think, it's time for me to create a github with all I have. To make changes in firmware I use autoexec.asc that is started by ThreadX RTOS at each time camera powers on (there are commands, that allow to make changes in code memory). As for me, it's better than update firmware each time and be afraid to get bricked camera :D

    Z Cam E1 has 2 operating systems on board: ThreadX RTOS and Linux. RTOS is for all hardware communications, recording, accessing to H264 DSP and all other stuff. Linux is for UI and uplevel scripts. GUI is made in Qt. Each time we do smth in UI it sends a message to RTOS through a socket.

  • @storyboardcreativity


    One thing that can propose is to use your own server (cheap VPS will do) and (it provides all interface also).

    Github repository can be wiped (with all other of your repositories and all account) in seconds out if company won't like something.

  • @Vitaliy_Kiselev

    Thank you, I'll think about it.

    Do you know anything about MN34230 sensor (sensor from GH4 and that's used in E1)? As I see, 1280x720 120fps and 240fps seem like garbage. It's NOT because of H.264 encoder - I've unlocked MJPEG and result is the same - very unsharp frames (seem like upscaled with sharpen filter).

  • Does E1 send 10-bit to HDMI? And does it work for 4K?

  • Z CAM E1 Crash-Cam Spotted in Mission: Impossible 7

    Two weeks ago, Mission: Impossible 7 director, Christopher McQuarrie, shared on his Instagram a picture of a few crashed cams during the production. Those were a bunch of smashed Z CAM E1 cameras on the set, which have been utilized as action 4K cams. After a bit of research, it’s was interesting to explore that the Z CAM cameras were used on previous Mission: Impossible movies as well.

  • @jleo

    Nice. Interesting if Z-CAM actually has different policy for top production companies.

    As for small companies or usual users they do not support E1 at all.

  • Maybe Paramount bought out all the E1's at $199 and have a warehouse full of them. Reese Witherspoon, Tom Cruise, both using ZCAM E1 and both are Paramount projects? Maybe they already read about the storyboardcreativity hack right here :)

    ZCAM might have to start making E1 again, if they can get parts.
