    @kurth, you said:

    @storyboardcreativity ....perfect ! You're the man...or woman? <...> And @storyboardcreativity....what were you running that got mjpeg at 200mbps ?

    I'm man, does it matter? :DDD

    About 200 Mb/s - I've made a patch, that helps to change MJPEG quality percent (to any value from 0% to 100%). Unfortunately, MJPEG's bitrate can't be controlled through this value, and bitrate depends on frame difficulty (it can work normally, but fall into "slow card" message on complicated scenes). You can find percent patch in my repository

    @Robby953, you said:

    @ storyboardcreativity 30-minutes time limit for video: I have a E1 EU version with this limit and it would be perfectly if i could do longer recordings... best Robert

    I've done patch for disabling time limit today - you can find it now in my repository

    I did not test it, but I'm sure it works. If it does not - write me, please

    Did anybody try to use HDMI (external monitor)? I see huge bugs:

    • UI with menu can be seen only on internal E1 monitor

    • But all liveview is on external monitor (on internal monitor frame is glitched and frozen)

    Only I have these problems? Or smb else?

    @Bob_Hawk, "MB/s" and "Mb/s" are different:

    MB/s - Megabytes per second

    Mb/s - Megabits per second

    @Bob_Hawk, thank you! I'll wait for your video

  • Bob_HawkBob_Hawk

    Storyboardcreativity have you found data for a save Hack with 80 - 90mbs 1gop ? on Limit or litel bit under the Limit from SD cart I use with Hack -- SANDISK EXTREME PRO 64 or 128 with write max 90 MB/s
    Without Hack -- works fine SANDISK EXTREME SD UHS-I 128Gb write max 60 MB/s Without Hack on 1080p60 works fine SANDISK EXTREME SD UHS-I write max 40 MB/s !!!! SANDISK EXTREME it`s to slow with Hack .....fail pics

    Thanks Storyboard for fantastic work ....all other ...You Know Hacking it´s Yor Risc

  • Bob_HawkBob_Hawk

    With the hack one should consider a few things the camera gets a lot hotter with the 100mbs1gop hack. Attention Read the data sheet of the sensor !! The Hotter the sensor the more noise The Themeratur is significantly higher ! I'm getting an IR Digital Thermometer tonight and will make a video about it tomorrow .. I will also remove the battery from the camera and measure the power consumption without and with hack.

    I'm at a small rock band at the mixer and dokomentation with the E1 our appearances ,while the E1 is up to 5 hours running on the power supply with Accu. Last Night Record 6x64Gb sd 2x128Gb Sd !! full

    On this Time Record Without Hack ... So far with hack the risk is too high for me on this Time .

    There are some E1 the heat dead Died weak point internal power supply and sensor is at 4K30p like times over 50 degrees C Hot.

    I test bevor i kill my cam --- it by quickly removing the lens and IR measurement

    Just added patch to repository with ability to force MJPEG quality percent.

    To use you have to use "Force MJPEG patch" with commands from "Force MJPEG quality patch" (you enable MJPEG and change quality). If you use quality percent patch without forcing MJPEG, nothing will happen.

    WARNING: If you set too high MJPEG quality percent camera will stop recording with "slow card" message (100% quality can cause ~400-500 Mbps bitrate - impossible for sd-card).

  • storyboardcreativitystoryboardcreativity

    Checked zLog mode with MJPEG - much better (with higher quality percent is much-much better)

  • pureaxispureaxis

    hmm I'd image frame rate would go up if its 8bit or pixel binning

  • storyboardcreativitystoryboardcreativity

    @pureaxis, according to MN34230 datasheet: "Full scan 10bit mode (22.5 fps)"

  • pureaxispureaxis

    @storyboardcreativity so it can capture 4:3 with 4644x3506, what would be the max frame rate?

  • zjavierzjavier

    all the photos whatever they are in dng have a size of 30.8 mb ... this seems strange to me ... I think something is not optimized ... the truth the quality should be better in less file size

    Just got all MN34230 sensor input modes in E1:

  • zjavierzjavier

    thank you very much @storyboardcreativity, maybe out zlog, only normal mode you can make something, let's have faith of all the good things that come

  • storyboardcreativitystoryboardcreativity

    @zjavier, I'm working on video side now - have too awful quality in zlog mode (not because of 8-bit mode, but because of too low h264 compression quality). Footages after grading become garbage.

  • zjavierzjavier

    Thank you for your answers

    The difficulty is not having an external monitor for continuous video recording. I have noticed how deficient the automatic focus mode, I hope we can do something

    in relation to having DNG photographs in 16: 9 format do you have any ideas?

    any improvement for the great compression and lack of detail in dng?

  • storyboardcreativitystoryboardcreativity

    @zjavier, there is a special assistant to watch center of frame to focus correctly (but I use an external monitor to do focus with focus-peaking mode)

    @pureaxis, I still can't find code that does this stuff. If smb could help me with determining DSP architecture, I can reverse DSP code

  • pureaxispureaxis

    I don’t think peaking is possible as it probably require coding new features. I’m just hoping for an open gate mode that captures full width of the sensor.

  • zjavierzjavier

    hi people @storyboardcreativity the monitor of the camera does not allow to see the focus comfortably, is it possible to add focus peak fuction as the image shows attach?

    on the other hand photo in 16: 9 format please

    Any plans to improve the quality photos? focus improvements... any others

    his contributions are great

    @MikeLinn, that's a very strange situation lol

  • Bob_HawkBob_Hawk

    The chipset it's for Consumer Cams, Codec embedded, the E1 Sensor have 10bit ,the Chipset can only 8 Bit, For PRO Res codec Need modern Chipset look of teh new FF E2 8K pro res .....4x Bit Rate from 4k ....16x Bit Rate from 1080P...... With e1 100k1gop Hack my e1 Record 0n 106mbps on 8bit Codec....... Pro Codec Need pro Hardware !!!!!!

  • MikeLinnMikeLinn

    I have a little inside from Z Cam - I spoke to one of the developers and he said that they don't like Ambarella SoC's very much. They said that their SDK is very buggy and they don't get any support from Ambarella. Now Z Cam change their vendor because of these problems.

    You know that Z-CAM had been founded by ex Ambarella engineers, right? :-)
