Z-CAM E1 Camera 100 Mbps hack for 4K DCI (fw v0.31)

    Hello @ storyboardcreativity Do you have anyone who has an E1 with display damage?

    a possibility found the internal display s.Hdmi output output or the wlan automatically turn on

    izugar uses a configuration file for the E1 Remote

    Cool would be too

    Configuration for STA mode -> E1 connects to wireless router (Settings zz only possible with IPHONE)

    Just found this thread -- pretty amazing work, storyboard.

    For those having problems creating their own autoexec.ash file, in Windows I had to delete the carriage return characters, but keep the new line characters. I also made sure the last line was followed by a new line. Either way, it worked after I made those changes.

    If just copy/pasting from Github, Windows might insert /n/r. I used Notepad++ to remove them by replacing /r with nothing. I've attached my custom ASH for example that works; it just needs to be renamed appropriately.

    Side comment/question/request,

    It was mentioned on page 10 that Storyboard saw support for 4K over HDMI? For the life of me I haven't been able to get 4K to work over HDMI yet with the E1; just 1080p. My 4K capture device works great with my Panasonic G85, clean 4:2:2 4K out over HDMI, so I'm not sure its an issue there.

    Considering how hot my ZCAM E1 gets when recording to SD card @ 4K, I'm hoping to instead record over HDMI to try to reduce the load on it; perhaps do some real-time noise reduction with my Nvidia RTX prior to compression.

    kurt and adybady can you guys post a link of exactly where your getting the files because I haven't been able to make it work yet!

    You can check the bit rate of a recorded file by looking at its properties. On the second tab of the details it should show you the bit rate stock it should be around 60,000 if the patch is working 100,000

    let us know what you find?

  • adybadyadybady

    Thanks @kurth I got it working. Saved directly from the browser on the raw page at github did it.

  • storyboardcreativitystoryboardcreativity

    Guys, sorry for my big delays between messages. I'm very busy with "true-resolution slow motion" hack. Still can't find what registers I need to change for MN34230 sensor. Where can I find documentation for this Panasonic sensor? Any ideas?

  • kurthkurth

    @adybady sorry....when I saved as, after bringing up the raw , and put that file on my card, I got well over 100mbps for dci with multiple samples, as have others. So it works. Start again with a freshly formatted card. And the v31 firmware I believe I downloaded from zcam fb page. If your camera is running 0.31 then your fw has to be good. I did get stuck for a while until I learned how to get the correct file off github, and when I had the wrong format of the file, it appeared to me at that point to also not work. So chances are that's your weak link.

  • adybadyadybady

    This still doesn't work for me @kurth :( I was doing that already (saving the fiel from RAW) and if its line return related, my files were already using UNIX format line returns (I use Notepad ++ all day and this confirms it was already in that format).

    How bizzare, what could I be doing wrong... my understanding is that with the 'Cumulative Patch' file (not edited after downloading) I should be able to select any standard 4k format for video recording and it will just work. Am I missing something there? Are there other settings in the camera that need to be set to specific things ?

    You don't still have the download of the firmware do you in case its different to the one currently hosted by zcam ?

  • kurthkurth

    @adybady ....see my feb 23rd post on page 3 of this thread

  • adybadyadybady

    I downloaded the v31 from the zcam site a few weeks ago and have just gotten around to trying this and it just doesn't seem to work. I get peaks of 65/70mbps occasionally but it still seems to be recording at around 60mbps on the whole. Did zcam release anew version of the v31 firmware that stops this from working or am I using a setting that doesn't work ? To clarify, I'm using the cumulative patch from the github page.

  • storyboardcreativitystoryboardcreativity

    @RussianBlue, yes. If you are Russian, you can write me in Russian :)

  • RussianBlueRussianBlue

    @storyboardcreativity, my mistake: I meant to say that in FW 0.30 only HD video is output to HDMI. I have not yet tried 4k HDMI output with FW 0.31. In any case, the HDMI output is always an uncompressed signal, correct?

  • storyboardcreativitystoryboardcreativity

    @RussianBlue, doesn't E1 export 4K through HDMI? I saw this mode in E1 firmware (4K 24 fps HDMI).

  • RussianBlueRussianBlue

    @storyboardcreativity, Will the Z-cam E1 WITH the cumulative patch output 4k over HDMI? It does not with the normal FW 0.31. Also, could a similar patch be used for the Z-CAM S1 VR ? It has four lenses and SONY Exmore sensors...

  • Bob_HawkBob_Hawk

    i dont use MJPEG .....i use 264 without ! Log.....with Flat curve with the cumulativ patch !!! i miss on pach for 1080p50 and 1080p60

    on the last update kill Zcam the old flat log he was a flat curve easy grading with BMMCC Cine lut

    to on 264 extreeme critical ZCAM2 Lut

  • storyboardcreativitystoryboardcreativity

    @RussianBlue, I very often use my own patches for making videos and never had problems with overheat before (I always record 4K + record with external HDMI recorder). I can try to check it soon.

  • RussianBlueRussianBlue

    @ storyboardcreativity,

    Thank you for your really exciting work! We love the Z-cam E1 and have six of them that we use regularly to create multi-cam videos. After trying your hacks at all resolutions with a Sandisk Extreme Pro V30 SD card, only the HD resolutions appear to work reliably for extended recording times. Heat is definitely an issue. The cameras do get VERY hot especially at recording 4k resolutions, and they usually freeze after about 17-50 sec of recording time. Would your MJPEG percentage patch allow us to ramp up the data rate in percentages to find out what would constitute a reliable data stream for higher resolution recording? Many thanks for sharing all of your research!

  • storyboardcreativitystoryboardcreativity

    @Bob_Hawk, wow, I did not think that somebody can donate me for my development. I don't even have patreon or anything else. I'll think about it. Thank you!

    About "auto_wifi" mod - I think, it's not difficult. I'll try to do it very soon.

  • Bob_HawkBob_Hawk

    or over Patreon ---> https://www.patreon.com/ i make your first sponsor

  • Bob_HawkBob_Hawk

    Storryboard I would like to thank you for your excellent development and donate me financially

    25 € in any case

    if that with the automatic wifi when turn on or the complete display of the internal dispay on HDMI output

    Does this work worth 50 € for me as an amateur

    PayPal ...or other Way

  • storyboardcreativitystoryboardcreativity

    I've noticed that when pipe sends 1536x288, from sensor we get 1536x384. Seems that we still can increase resolution for capturing slow motion.

  • storyboardcreativitystoryboardcreativity

    Ok, I've reversed almost whole pipeline from photodiode array reading and to saving video to file. Patch for "true 240 fps mode" is done, tomorrow I'll test it on real optics and scenes.
