    @AdvUser, lol, it easily can be done. Today I'll do it.

  • AdvUserAdvUser

    @storyboardcreativity Sorry, of course I meant the possibility for not 50-60 MB/s but 50-60 Mb/s for HD :)

    Zlog2 (graded), 100Mbps 4K30P handheld:

    Lumix f2.8 12-35mm OIS lens.

    @storyboardcreativity you came here originally for a reason....we all know why....you should stay here for the same reason. Github is for coders, not photographers, or videographers. Thanks. You did a great job. I personally would like to see a patch for the 720/120/240p. And for 1080p @100mbps. That might be where this little camera shines.

    You think like developer. Adding one more hurdle always filter people, from 10x up to 100x less will go to your place (I mean here people who already used to some other way).

    @Vitaliy_Kiselev, lol that means bugs will not be fixed. If they need it => they do it

    It is not better, as most people will stop doing this (you need to register, etc). Personally checked such.

  • storyboardcreativitystoryboardcreativity

    And it's better if people post issues to my github (for example, if camera has bugs, I can try to solve them).

  • storyboardcreativitystoryboardcreativity

    Did anybody check is there a 30-minutes time limit for video? I see code that sets 29 minutes time limit if camera's region is "en". If smb has problems with it I can disable limit.

    @AdvUser, yes, 100 Mb/s 4K 25 fps possible. I'll do this patch soon. But 50-60 MB/s is not possible now due to UHS bus (I try to overclock it, but it does not work now).

  • AdvUserAdvUser

    @storyboardcreativity is it possible to make 100Mb/s bitrate for 4K (3840x2160) 25fps as well and higher bitrate (50-60 MB/s for eg) for HD resolutions (1920x1080)? Thank you.

  • kurthkurth

    gracias!

    @kurth Just "save as" a Unix script file and change the .bash to .ash; if you have an .ash file already being edited, just save to keep the .ash extension.

  • kurthkurth

    @rjhinde....thanks...did that but can't see where notepad++ saves to .ash...not in save file as, nor in preferences. Is it language>actionscript ? Nope....that ain't it !

  • rjhinderjhinde

    Just make/copy an .ash file and paste the lines from the file(s) you want to include. Use a text editor (I use Notepad++).

    Then you can add all the options you think you might want and comment out the ones you aren't currently using.

    You can add your own comment lines to make things clearer for you.

  • kurthkurth

    What I like to have explained is how to combine 2 or more .ash files on the card ?

    Firmware 0.31, the Hack (100 Mbps), Zlog2 and the Zlog2 LUT Test Video

  • rjhinderjhinde

    @kurth, thanks - I figured it had to be a line return thing and found the raw button eventually. I think that there may well be others like myself who are not regular Github users and will fall into the same trap.

    Now, what configuration changes are possible and what values are acceptable?

  • kurthkurth

    @rjhinde....and everyone who's confused.

    open the .ash file....you see the code in a window. Hit the raw button on the right. The code opens again. Right click "save file as" ....ash will save to your comp. Put it on your card. That's it. I'm getting, for a complex scene, up to 115mbps for dci4k.

    Hello. Alot of us would love to see this applied to the 2432x2432 firmware! Is 60fps on 2432x2432 still impossible for the E1?

  • Bob_HawkBob_Hawk

    Hello it is possible for E1 a pach to make the file at the high frame rates 120FPS soo save the recording at 120Fps in the playback but with 30FPS is played back for slow motion

  • rjhinderjhinde

    Okay guys, this sounds great BUT I cannot get this to work. I have E1 with 0.31 firmware installed. I cannot download the .ash files directly (Chrome just gives me an HTML page with the .ash extension) but I can generate a script file that looks OK using Notepad++, and save as a Unix script format so I assume line returns are correct.

    I've had no problems writing and using CHDK scripts in the past, so I must be doing something pretty stupid here.

    A .zip or .7z archive would makes things easier IMHO.

    When I put any of these .ash files in the root directory I see no difference in any of the recorded videos; they are all h.264 AVC at 60Mb/s.

    ,ash files like the mjpeg one doesn't require any configuration as it is presented, does it?

    Also, some of the scripts accept values, is there any explanation of what values are acceptable?

    Is it practical to have all these options in one file, and to comment out the entries we don't need?

  • ChumbyChumby

    @storyboardcreativity - I don't have the camera in front of me, but if using it as a streaming device my memory is you can output 720p and 1080p through the mini hdmi port? Just wondering if the faster bitrate can be pushed out here?
