Official GH2 "Stalin" hack development topic
  • Vitaliy_KiselevVitaliy_Kiselev
    As we moved from dumping to reversing this topic will containg actual info and discussions.

    First good news. It looks like all video related setup routines in GH2 work in RAM, instead of ROM for older models.

    The gent who asked how you know if you got the hack loaded. Well if you look at the time from a 64Gb card you'll see perhaps 2 hours or less but with the regular firmware on 24p I see 6 hours available on the card. (bottom right of display window). Very unscientific but perhaps useful.

    Not sure if this was just me but I was unable to get the original firmware back onto my hacked Gh2 but I finally figured it out. Here is how I did it. (I am using the bog standard firmware as I need to shoot a 5 day seminar 8 hours a day :))

    I struggled to DOWNGRADE to the stock firmware, v11 from a hack / upgrade I did to my GH2 a year or so ago: Got the firmware here: http://av.jpn.support.panasonic.com/support/global/cs/dsc/download/fts/index2.html

    Camera complained about no image found - looked like it just ignored the firmware file. Tried download it on a windoze machine too. But I also noted if the version you are trying to upgrade to is a lesser version that what you have in the camera then it may give that message too :)

    See PDF. http://av.jpn.support.panasonic.com/support/global/cs/dsc/download/fts/step_b.html

    So, I launched Ptools3.ext and loaded the firmware V11 from panny - it automatically incremented the version for me and then I just saved it without loading a patch.

    So still had a virgin version of the latest albeit 2011 version of the firmware but now incremented. Now I was able to load it using the prescribed method, holding down the play button after turning the camera on.

    Kool!!!

    @levidrums, the actual bitrate you get depends on the content - some footage compresses much better than others. Fine well exposed detail & movement will take more bitrate, so try to shoot sharp footage of eg. foliage, trees, complex detailed patterns and move the camera a bit. There are also stress-test PC patterns out there that you can film to push the bitrate (and also test if a hack is stable).

    Some hacks can be combined (eg. a 720p hack and 1080p hack) but it's complex as (IIRC) some settings are shared between modes, so if you want that I'd look for someone who's already done it. You can't have multiple hacks for the same modes without reflashing. Some people carry different hacks on different cards and just flash on location to whatever they need.

    Hey

    I have quite possible a silly question but...how exactly do you know after you hacked the gh2 that you in fact have that exact hack. I recently got the cbrandin's mbp's 44 and when I shoot on 24fps the file comes out in (average) 30000 kbp and when I choose high bit rate the file comes out as (average) 20000kbp...does anyone know why is that?

    Also can we have more than one hack in the camera?

    Thanks in advance.

  • oniononion

    thanks zigizigi

  • zigizigizigizigi

    Yes, it is. Your camera can be made PAL/NTSC switchable with the hack. In PAL mode you can chose between 24p, 25p and 50i. The only limitation is that an SD card that has files recorded in NTSC mode needs to be reformatted after switching to PAL.

  • oniononion

    I have a US version of GH2 - is it possible using the hack to record 1080 50i?

  • fatpigfatpig

    are the film modes for GH2 still being worked on?

  • sentongosentongo

    hello! vitality.... am so great-full for the work you have done to improve on my Panasonic g3 by your powerful ptool software . please my point as to why am writing this is to inform you that am ready to be better tester for g3 if thier is still more patches and hacks i have three bodies that are working very very well and are all patched with the new ptool you gave us. my email address is sentwaterbus@yahoo.com and am from Uganda in East Africa may God give what you want..

    @Vitaliy_Kiselev

    Ok Thanks I was just wondering if this operation was compiled in a piece of code that we could maybe manipulate

    Thanks Anyway

    Is this something that is not physically possible or just something you can not do?

    No one except Panasonic enginners knows if it is physically possible . Most probably not.

    No

    Is there anyway of adjusting the ETC mode in Movie mode so that instead of cropping to 8mm it crops to say half the sensor 11mm. I would like to use 16mm cine lenses but the sensor crop is too much really to justify the use of old c mount lenses...Is it possible?

  • Vitaliy_KiselevVitaliy_Kiselev

    Is there still some development going on for the modified picture profiles on the GH2?

    I did many experiments, no big results yet.

  • simonstar66simonstar66

    Dear Vitaliy. Is there still some development going on for the modified picture profiles on the GH2? Or are you completely concentrating on the GH3 now? No offense. I'm just curious.

  • _gl_gl

    I'm also still really interested in film modes.

    I'd also really like to see on-screen (and preferably record) a negative version of the image.

  • hedroxhedrox

    @JPB1138 +1 for the less contrasty flat look, this could be big improvement in gh1/gh2 IQ ... thanks for the info @Vitaliy_Kiselev, will donate soon as I can

    one more question, are you working allways alone on the hacks? It´s just my stupid idea, but would be there maybe some hacker that could help you with the development? maybe an article on m4/3 rumors that you are looking for developers or something similar could maybe help? I know it´s not easy thing to do, just don´t know how to help you except donations and writing less posts on this forum :)

  • JPB1138JPB1138

    @Vitaliy_Kiselev Thanks alot. It would be a great chance for exploration and new looks, if you can achieve it. Hope to hear more soon!

  • Vitaliy_KiselevVitaliy_Kiselev

    @hedrox @JPB1138

    I am working on this, I just had very small amounts of free time lately.

  • JPB1138JPB1138

    @hedrox I am also very curious, but its been so long I doubt any more progress. I would love a less contrasty flat type look, just a little more flatness would go a long way in some situations.

  • hedroxhedrox

    Hi @Vitaliy_Kiselev , just wanted to ask how is the development of film modes hack going? any news or is it stopped now? I would really like to know if it´s possible to tweak the film modes settings, thanks!

  • ryusaebaryusaeba

    Sorry I am late to the thread... is there an update to the hack since Feb. of this year? I am still very interested to see fix for Chinese language support in the menu. Many thanks to people that contributed to this project.

  • fatpigfatpig

    I think this is not a forum for people that would want to use anything automatic in this camera ;)

  • zigizigizigizigi

    @Vitaliy_Kiselev

    Have you ever investigated the possibility to make AF/AE lock button work while recording? Is it possible to enable it via hack? Obviously, if lock hold is set to ON in menu the lock button DOES work while recording but only once - it releases the previously locked exposure. Couldn't there be just some code intentionally switching it off for the rest of the session?
