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

  • thanks for the test result with the noise, you are probably right. the sensor of the E1 sometimes gets over 50 C during operation, the iphone app shows the sensor temp, because every sensor is noisy higher temp-higher Noise ,Blackmagic Cams have better cooling .

    The 100mps makes itself felt drastically with movements and fast light changes by changing from a fixed 50 mps to a variable 100 mps. with static image without much movement you still have 50-60Mps with a lot of fast movements, it rises drastically to over 100Mps. Without mod, a lot of moving artifacts appear .

    the processor in the E1 is very limited in performance, so I reduce the noise reduction in the camera and move it to davinci resolve

  • I sat down with a very sharp Cine Lens and did side by side comparisons and the noise I am getting with the 100 MPS hack is actually causing Image Quality degradation. I then denoised the 100 MPS video and the 60 MPS video looks better under 100% enlargement. I know a ton of work went into this and I am not trying to be disparaging but the Noise outweighs the extra 40MPS of information.

  • @storyboardcreativity Thanks so much for your awesome reverse engineering work!!

    I’m trying to squeeze every last drop of performance out of this camera. It’s challenging I’m not gonna lie!

    I used your UHD 4K 100Mbps script. It works well.

    There are still issues I have with the image coming from this camera. The color fidelity is very off - showing lots of pink and green splotches in the shadow areas. I noticed that this is a very noisy sensor and maybe this color artifact comes from their 3D noise reduction. I saw earlier in this thread that you were making progress with disabling that. Have you managed to do so? I think if the chroma noise was more uniform the artifact would be less noticeable.

    Also, I’m recording at 100 ISO, but I still get more sensor noise than I would expect at such a low ISO. Is the camera lying to me? I hope to get the sensor to record with no, to very low gain so that I can get back light using fast full frames lenses + speedbooster. Do you think you’d be able to investigate if we can get ISO less than 100?

    Here’s a video sample:

  • Hi,

    I'm using the Z-cam E1 in astrophotography. It works well. The lower shutter speed is 8 seconds.

    Is it possible to lower this speed, down to 20 or 30 or 60 seconds (or more...) with a hack of the firmware 0.31?

    Thank you very much.

  • The hack only work with FW 0.31.--With the other FW you risk a frozen or Kill your cam

    The individual hack only change a very specific resolution. The cumulative hack only combines several resolutions.

    Find out for yourself which : Resolutions - Frame rate and formats hack supports .

    If you don't know exactly what you're doing with a hack, you risk turning your camera into a brick

  • @Bob_Hawk the 0.31 is the latest firmware, but are you saying that any other format besides 16:9 will make the camera overheat?

  • Hack only Firmware 3.1 only the exact Size and fps Lower Fw Kills the Camera ...Overheat

  • Amazing thread and amazing results. Thanks guys for all the effort you've put into it!

    Would it be possible to activate the hack on the 4:3 (30fps) resolution? and also on the 2432p (30fps) 1:1 resolution (izugar firmware)?

  • @orey10m....jump thru the hoops like we all did

  • Hi all, Just picked up m ZCAM e1 again for the first time in a while and tuning into this thread. Can someone summarize what has happened here? Apologies as I don't really follow alot of the lingo. I'm particularly interested in anything at 48fps or 60fps with improved bitrates? Was that achieved?

    Can I download a hack somewhere and try it on my sd card? Thanks for any help !

  • @Bob_Hawk

    We have nice separate topic for this lens - http://www.personal-view.com/talks/discussion/15754/42.5mm-f1.8-xiaoyi-macro-m43-lens/p1

    In hack topic it will be few people who will find your note.

  • Thanks vitali i Transfer

  • Imagine back then, when that was much more important.

  • @mei Yes, I can imagine. It's the Z Cam E2C. $799.

  • Finally, something that was needed when the camera cane out.

    Has anybody manged to overclock the circuites to get 4kp48/50 at 2.41:1 ratio (to help reduce the amount of overclocking needed), or to try a little under rez window at 2.41:1 to get it closer again to normal?

    One of the developers told me the camera uses a 1080 HDMI part a long time ago, and that's why it's limited to 1080. If only the camera could have done 200mb/s 4kp50/60 with a little better pixel format, with clean HDMI out, can you imagine what a camera it could have been?

  • I reached out to several of you on this board and xyster who is cool cat emailed me his patch file and it worked first try 105 MBS per second! So something in the downloading process is affecting the files.

    Thank You again xyster for your help!

  • Unzip the File and Copy the ash File from Folter to micro cf Card ........And use it

    !!!!!!!! to learn what you are doing .... read the chat history from the beginning.

    !!!!!! that's hard ... but that's how you learn

    storyboard has answered all your questions at least once already

  • Ok I just went to my SD card and opened the autoexec.ash and this is what I have on my card.

    Strangely whats showing here doesn't show the # that are present at the beginning of each paragraph.

    change VBR max percent from average bitrate

  • 1.) 100% function my Tip: > use the function -> clones and Save right in the green field

    2.) THE HACK Switch from --- constant Bit Rate to variabel Bit Rate

    3.) 100 Mbps Max Bit Rate on 4k30p with many many moving in complet Pictures

    Read this Chat from site 1 to site 11 and you found all over this Hack

  • I have the camera updated to .031 and I have tried downloading the zip file and I have tried getting the file using the raw button then "save as" and I am still only getting 57837kbps.

    What the heck am I doing wrong?

  • --> the easiest way is --- Ever ( :-) <--

    -> go to the start page -> as in the picture

    -->and use the function -> clones and Save right in the green field

    -> and download everything as a zip file

    -> save it on the desktop

    -> then you can copy the respective autoexec.ash from the respective folder --> to Camera

  • -> Go to the file you want to download.

    -> Click to display the content within the GitHub UI.

    -> press upper right on RAW key .--> pic 2

    -> Right click -> Save as ... -> pic 3 and change the name From--> autoexec.ash.txt !!

    --> To -> autoexec.ash <-- delete the ending -> .txt !!!!!!!!   Tip ---> create a folder with subfolders with the respective name !!! because all files are called autoexec.ash

  • I am still having trouble downloading the autoexec.ash file from the site. I click on the Raw button and then when I try to "save as", the file saves as autoexec.ash.txt file. What am I doing wrong? Or what's the best way to download that file in the proper format?
