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

    Just could bypass tuning system of E1. Now video is not resized in 120 fps and 240 fps mode (you get real 1536x512 and 1536x288 videos on sd-card). It can help to reduce amount of artifacts (because pipeline before was: sensor -> pipe -> resize -> MCTF -> h.264 -> sd-card). There were a lot of artifacts after video resizing. Now next target is to reduce steps between sensor lines that are read during capture (because now video seems "flattened" vertically).

    @Bob_Hawk, hey! Can you provide me their 240 fps video and firmware version, where it was good? Maybe I can make changes in firmware to reach same quality.

    Why does eric such a shit !! The sensor had a 2x2 mode for 1080p and a 3x3 mode for 720p240 I have a suspicion In one of the earlier versions before 0.31, Zcam had shown a great 720p240 video with a bursting water-filled air balloon ??? it would be interesting to check the last update and the version of IZugar, which still sells the e1

    Today checked the "real" (from sensor) resolution of "1280x720 120 FPS" mode in E1 => it's 1536x512

    @storyboarrdcreativity have you any cance the 4k24 push to 4k30 ? , and Auto Switch on wifi ...this was a Killer Future For E1 with Defekt Displays

    @Vitaliy_Kiselev, how can I contact them? :D As I understand correctly, they do not use Ambarella SoCs already (after E1).

  • Bob_HawkBob_Hawk

    He have nothing intrest on Zcam E1 Update

  • Bob_HawkBob_Hawk

    Zcam Talk he don't use ambrella ? He Talk use Asic and many Core risc Cpu .?

    @storyboardcreativity

    Try Z-CAM :-) They have big shortage of people.

    @cofhal, well, it's a very good question because I did not think about user notification. I'll make something for it soon!

    For all others who waits for my answer: sorry for being away for a long time. I'm just looking for a new work. Does anybody know any vacancies for Ambarella programmer or anything else? :D

  • cofhalcofhal

    How can I check that the patches are really working? I copy these to the microSD but when I turn on the camera I don't see any changes.

  • Bob_HawkBob_Hawk

    cumulative patch - enables 100 Mb/s bitrate and All-Intra mode …its universal

    Full HD 30 and 60 miss

  • Bob_HawkBob_Hawk

    on 1080p30 its lower / 1080p60 50-60Mpbps / record on 4k and you come to 80to90Mpbps

  • PeterLesboPeterLesbo

    OK... I got the camera updated to version .31 YAY ! !

    I downloaded the files and placed the auotoexec.ash file (1KB in size) onto the root directory of the SD card and I am still getting 60 MPBPS files...

    What did I do wrong?

    Peter

  • Bob_HawkBob_Hawk

    Sorry Unfortunately, full HD 30P 60P is missing

  • Bob_HawkBob_Hawk

    hello storyboard 1.) Did you manage to put the menu of the built-in display on the HDMI output This will make you the hero of all those E1 owners with a faulty display like me

    2.) I am filming in full HD in 30p und 60p unfortunately lacks the cumulative patch, when mixing with 4k 30p super

    @PeterLesbo see the download link in this Facebook post from Z CAM https://www.facebook.com/groups/175043642931144/permalink/564716383963866/

    Note: Don't install on iZugar model E1 or you will lose the 1:1 aspect ratio for VR180/360.

  • PeterLesboPeterLesbo

    Hello

    I am trying to get my E-1 updated but the E1Fw.bin file I downloaded off the Z cam's Facebook page updated my camera to a version .30 not .31

    has anyone seen anything like this or know how to get the correct file?

  • storyboardcreativitystoryboardcreativity

    @Vitaliy_Kiselev, no, I can't. E1 can play only 4:2:0 AVC MOV files and show JPGs (4:2:2). No any way for me to show RAW files or anything else.

    @storyboardcreativity thanks for all the great work! Love the 100mbps hack.

    I have a question: I've recently started working in a project that involves filming calculus classes that are taught in a very wide blackboard. I shoot it in 4K using the E1, and crop out 2/3 of the image in post to isolate the blackboard and superimpose it on the final multicam video. The board's aspect ratio is something like 5:1, so I was wondering: would it be possible, using your hack, to add resolution profiles with different aspect ratios? In my case, something like 7203840 or 7684096 @ 23.976fps and 50mbps?

    I ask because, at 100mbps, I waste a LOT of space with each 2 hour class. But at 50mbps, using only 1/3 of the image, the artifacts sometimes blur the smaller calculus symbols used by the teacher.

    Thanks!

    "when you choose "720P 240 FPS" mode, actual readout from sensor is 1536x288! " Isn't it 1546x384 cropped down from 3x9 binning output (1576x394)?

    jeeep its a funny thing

  • storyboardcreativitystoryboardcreativity

    Hey, does anybody need to view all screen OSD from LCD on HDMI? (I mean menus, settings and etc.)

  • Bob_HawkBob_Hawk

    On hdmi output by 4k it's 1080p ...JASON Chang Love supersampling

    1. Sensor give 4k30p Record on SD Card
    2. Intern Display give ca. 240x360 Video on Display
    3. On Live vew to wifi creapy diffrent Resolution 4..On HDMI make 1080P

    The limitation ist the Chipset For 800$+Tax you became the Z Cam E2C

    On last Week i became my 2end E1 For 200€ .... for me it's E1C in Beta Test Status and Not stabil

    With your Perfect Hack " 100mbit 1gop hacķ " i t's the E1 a fine Cam For me thanks a Lot i Love it

    Please Don't over Future your Hack ...make Practical Stabile Hacks ......Not the same mistake from Jason

    @Bob_Hawk, I need 24p HDMI out because I record in 24p. I don't know what to do =/
