    First, no one can tell you why you card behave such. May be you have problems with your Mac reader (bad contact and contacts on card are already quite worn). Use other card.

    >for instance searching for "Volume", so tweaking microphone sensitivity

    Look at the hits at the right. They have enough description for this setting.
    If you do not understand, you can always ask.

    @ Vitaliy, so you suggest Transcend cards are bad quality and it happened because of this? Of course I did try to reformat the card, doesn't help - also it's readable in my GH13, reformatted it there as well, didn't help either. So might actually be simply a card failure...

    Regarding "you not understand that you are doing": I experimented quite some with GH13, and as far as Stalin hack is concerned, I don't find much info here or elsewhere (for instance searching for "Volume", so tweaking microphone sensitivity, think that there's nothing written about this patch yet, or is there?) - so how to find out, if not by trial and error?

    Bought a Japanese model. Just a heads up as the US models seem to be Made in China and the Japan and Taiwan models - made in Japan. On my various GH13s, the best picture was out of a Made in Japan GH1 2010.
    You can buy Gh2 from Japan from Amazon.co.jp or Rakuten.co.jp (dont select international)
    Use Google Chrome or add-ons for language translation.
    Then use Tenso.com for shipping. You have to use DHL due to the Lithium battery.
    922 USD before shipping.

    Progress has been made with 720p. We now have 28 mb/sec average 720p @ 60 FPS with B frames.

    @zigizigi >> If so, codec tweaking is of no help here - the 50i will be always behind in terms of apparent resolution. It's just made so.

    I'm afraid you're right

    @mpgxsvcd >> Whenever we try to raise the max bit rate it keeps the average bit rate the same.

    Unfortunately i've made the same experience. So at the moment the hack does not provide a better image quality. Hope to see 25p or 50p soon.

    First, looking at the settings, you not understand that you are doing. :-)
    Second, use good SD card and format this one after this place it far far away.

    Hi, I was quite excited to read all this too, so I loaded the new firmware onto my GH2 - but something weird has happened: it seems to have bricked ... my SD-card?!?
    Settings I used were:
    - Version incr.
    - 30min limit ...
    - PAL <->NTSC
    - 720p compr: E3 Quality, E3 Table
    - Microphone: Volume Indic 1-8 all checked (wanted to try that, without fully understanding, so don't know if this makes sense but it's probably not relevant here anyway...)

    Upgrading firmware went fine, then inserted another class10 sdhc (Transcend 16GB); tried to record 720p footage which apparently worked - but when inserting the card into my mac, it didn't show up. It's recognized in the camera (although 1 time I tried it wasn't, but usually it is), but it's never recognized on the mac - other cards are, so it's not the card reader...
    I mean could theoretically also be a coincidence, like the card was already broken before and I just didn't notice until now - but then it's strange, the cam still recognizes the card...
    Mac doesn't tell me either, there's some unidentified flying storage device or whatever, just completely ignores it...

    So I'm curious, if anyone has an idea, how this can be caused, or whether this will be happening to more people (hopefully not!) - apart from that, it's great the FW-hack worked out and I'm also very curious of things still to be developed :-)

    Great work, thanks Vitaly. I really appreciate it. No more silly 29:59m limit indicator, no more choppy PAL framerate.
    720p60 works fine and higher audio bitrate, too. Later on I will test higher video bitrates, but not yet.
  • JaapsbJaapsb
    Thanks for the hack Vitaliy, great work...sorry but I have to ask, because a lott of people in the RC world are waiting for it, and I read you did something with hdmi but:
    Live view through composite during video recording (ever going to be) possible ???

    I've created HACKchart, a 1080p / 16:9 test chart (attached). You can print it, and then shoot it to debug frame corruption (especially fps / bitrate testers).

    Having a standard chart will make it easier for V. and other testers to analyze wrong aspect ratios, corrupted colours and where parts of the sensor image end up in a scrambled frame.

    If you get problems like that, shoot the chart so it completely fills the frame (or close-as) and post the a screen grab.

    Another interesting thing is that if I raise the 24p bit rate above the 720p settings but below the original 24p settings it still gives me the same result as using the 720p settings. It almost seems like if you use the 720p or 1080i settings then you will get 17 mb/sec average video. If you use the 24p settings then you will get 22 mb/sec video. However, that only works for 24p and not 1080i or 720p.
  • dkitsovdkitsov
    @mpgxsvcd I have the very same observation.
  • everoevero
    @Jon2323 1080 50i (pal models)/60i (ntsc models) have always been on the gh2, e.g. see spec http://www.dpreview.com/reviews/PanasonicDMCGH2/page2.asp but the bitrate/codec is not as good compared to the 24p cinema mode. But if you had at NTSC model, you can now use ptool to enable the NTSC/PAL switch, if that was your question.
    Please remember to google things like basic specs before posting - we would like the developers etc to spend time on the critical issues here :)
  • mpgxsvcdmpgxsvcd
    I know this isn't what everyone was hoping for. However, I have successfully got the GH2 to record 1080p @ 24 FPS at 17 mb/sec as an average instead of the original 22 mb/sec. The point of this was to determine what the camera did when we lowered the max bit rate. It appears to not only lower the max bit rate but it also lowers the average bit rate.

    Whenever we try to raise the max bit rate it keeps the average bit rate the same. This causes the codec to over encode, under encode, over encode.... and so on. I expected the codec to do the opposite when I lowered the max bit rate under the default value. It did not do this. Instead it simply lowered the average bit rate along with the max bit rate.

    In the tests I did the max bit rate was about 18 mb/sec and the average was about 17 mb/sec. When I use the default firmware the average bit rate is 22 mb/sec and the max is 24 mb/sec. Sorry I can't post screen shots and stream parser data at the moment.

    There simply must be another setting that controls max average bit rate. It may be in the Encoder Setting variables. I haven't tested those yet. However, it could be an entirely different variable as well. Is there anyway to search the firmware for every setting that has a value of 22,000,000 or 18,000,000?

    So the GH2 could do 1080 50i before the hack!! Think I've been out the loop, when did that happen, has there been a firmware update?
  • sebaltosebalto
    1080 50i was already ok before hack, as was 720 50p. 1080 25p isn't fonctionnal yet.
  • Jon2323Jon2323
    Hi guys, can I please confirm whether or not the new firmware/hack allows any kind of working PAL formats, eg 1080i 50i or 50p or 25p, 720p 50p etc . Thanks
  • sebaltosebalto
    @andycorleone I have tried to record with "yes" choosen and eventually the zooming occured ! But it led to a crash: no way to stop the rec neither to switch off the body. I had to remove the battery. I repeated the process two times to check.
    @dkitsov The magnification doesn't fonction even with patch above loaded when connected by HDMI to a monitor.

    @mpgxsvcd @Vitaliy_Kiselev I know you can tell from the release date, but the point of versioning software is that each version number is unique, even for minor revisions. Here we have different code with the same version number.
  • mpgxsvcdmpgxsvcd
    @Ptchaw

    From Vitaliy
    "PTool 3.60d updated
    Like all minor updates previously it can be spotted by looking at the release date in the PTool title." The latest one has 060711 in the title block.
  • Vitaliy_KiselevVitaliy_Kiselev
    @Ptchaw

    No. But it have release date shown in window title specially for this purpose.
  • PtchawPtchaw
    @Vitaliy_Kiselev If PTool v3.60d has been updated, surely it is a new version and should have a new version number?
  • dkitsovdkitsov
    @sebalto How about magnification for focus check? It also normally does not seem to work with HDMI plugged. Does it work with the mod?
  • andycorleoneandycorleone
    @sebalto "BUT the EX Tele ( the zooming ) still does not function when connected to HDMI :("

    did you try to start recording? and check the memory card in a computer?

    I not 100% sure but I think in the GF2 you don't see instant feedback of the Ex-tele Fucntion. but pretty sure the video recording is with the extender active.
  • Vitaliy_KiselevVitaliy_Kiselev
    @sebalto
    Got it.
    We'll be looking further on ExTele later.
