  • Talking about the second video demostration. At the end he said: "Remember, all the benefit of this patches will be lost if you recompress the footage" So, if I take the footage and use, 5dtoRGB or log&transfer, mpegstrem or compressor to make a proress for example, am I screwing all my highbitrates? Means that is better to edit in CS5, CS6 native mts? recompress a the end? I think that the footage will benefit equal of high bitrates because it will do a proper proress in case yo wanna mix several cameras or not?

  • Question about loading patches.
    When loading a new patch my gh2 shows loading 1.2 when checking firmware it says 1.1 is this correct? the patches seem to be successfully installed(my record times are changing) but something seems off.

    Also is there streamparser or something similar for mac to analyze footage?

  • flablo: observed, expected, predicted. Guaranteed? :P

    Jakartaguy, flashing the camera doesn't erase the camera's settings. But on occasion you will need to do menu, setup, reset, to get the camera to behave correctly. So make a habit of keeping your camera settings written down, so they can be reprogrammed if necessary. You can keep firmware image files on multiple cards, to flash them as needed. Of course formatting those cards will erase the firmware image files.

  • @balazer thanks for the advice. Can I ask a bunch of other questions? 1. Once I flash the camera, and the format the card, the settings are still in there right? It just seems sometimes my camera behaves oddly (like for photo styles, i believe my original only had Standard and Chrome, and right after the flash it has many more options. But when I format my card and turn the camera back on, it goes to just having those two options again. 2. I read that some people put different settings of hacks on different cards, but does that mean they don't format the cards? Because I found that if you don't format the cards the camera will ask you to upload the hack every time you push play.

    Thanks everyone for their inputs and guidance.

  • @balazer, do you mean with Cake I'd obtain "guaranteed" 45-50 Mbps

  • A modest increase of the bit rate won't guarantee that the encoder won't go into fallback mode. It will just make it less likely. Cbrandin 44M in 24L mode and Sanity 5 are a modest step up from stock.

  • I'm fairly experienced hack user with GH1 and GH2, but I've always played with how to get the best quality. Right now, I'm going to be doing a project where I'll be filming a ton of footage, but using little of it, but want what I do film to be good.

    So here is the question.

    What is a good hack that ups bitrate very slightly, and keeps the encoder from going into "fallback mode"? I want the files to not be much bigger if possible.

    Basically, what's the next step up from basic firmware? I've never had to deal with something quite like this. I may just keep the original firmware, but there will be a fair amount of shots of water and for those I'd like to not have the camera going to fallback/ugly macroblocking mode. Thanks for the help!

  • Cake is 45-50 Mbps in HBR mode.

  • Hello, I'm using a PAL GH2, and I'm trying to find the settings with the best quality/highest bitrate. I tried Flow Motion, Sedna, and others, but I can't reach the highest bitrate (shooting HBR 1080 25p). I shot a scene involving a singer on a white background, so no complex frame data, but the bitrate I obtained was 21 mbps with Sedna and only 17 mbps with Flowmotion. I guess that is because the scene is "simple" (2/3 white background, 1/3 singer singing and moving), the bitrate went down, but I couldn't get the best detail on the subject, there was clearly too much compression going on. I know Sedna could do more than 100 mbps, but the problem is that it DIDN'T and I went just 21 mbps. Basically the question is: how can I "force" the bitrate to stay high even without having a complex/busy frame? Is it just a matter of choosing the right patch with the right settings of GOP, matrix, etc for that kind of shot? Thank you people for your help!

  • Hi everyone, first post here. I did read a lot of topics and guides. I just got a GH2 for Aerial Video with a octocopter, I'm using a Nex5n and T4i for video, but sometimes both cameras lack the details needed. The problem is there is so many patchs that I'm confused. Can someone point me a good hack for aerial video? I need very good resolution. Thanks!

  • capebio, you seem to be confusing the lens firmware with the camera firmware. They are separate. The latest GH2 firmware is version 1.1. Your lens firmware is version1.2. PTool only deals with camera body firmware images. You should have firmware version 1.2 on your lens, and use PTool to modify camera body firmware version 1.1. Nothing will change about your ability to use that lens with the GH2.

    Jakartaguy, flashing your camera with a firmware image modified with new encoder settings won't change what you see in the camera's menus. It simply changes internal encoder settings. You'll know it worked when your recorded video has a higher bit rate and looks better.

  • @triton in the menu/spanner/page 3/video out = pal or ntsc :)

  • Hello,

    Anybody knows how can I find the menu to switch from NTSC to PAL and viceverse?. I checked it in the hack but I can´t find it. I´d like to shoot in 720/60p!

    Thanks for your help!

  • I just finished using ptool 3.66 on my GX1 and clicked the circles for the Cluster and Galaxy patches. I used panasonic GX1 firmware 1.1 was the base. When I put the card in the camera it went through all the procedures but now, nothing on my camera has changed (when I go to my settings I can't find all of the things I have put on there like the Cluster or the Galaxy patch, or choices of frame rates, etc). Any ideas what happened, thanks.

  • I'm currently using my GH2 with an Olympus 35mm macro lens connected with the DMW-MA1 adapter. However, compatability only came with Firmware 1.2 update (Otherwise I can't use the lens at all!). I'm concerned that in installing PTool (which I would really like to do), I will lose my lens compatibility - and can I backtrack to V1.2 if so? p.s. Olympus lens focus is accurate, but atrociously slow and illogical. Lens messes around for a few seconds before finding focus. I have to press trigger button three times to get it to macro range as it jumps about a third closer with each press, and then goes hunting for focus in the long end. :(

  • I finally got it rehacked. I just kept putting in numbers and clicking options in ptool and changed cards until something worked. When it did go to update it asked me if I wanted to update to ver 2.5 which seemed kind of odd as I was listing firmware 135. Don't care why it worked....all that's important is it did !!!

    Thanks for your help!

  • Mark....yes I tried it with checking "version increment" and without, no luck either way.

    Vitaliy.... by the smiley face at the end of your comment, I am assuming your comment is humor? I don't know what a hex system is, so not sure how to find that in my menus.

    Thanks for your input so far !!! :-)

  • B means just B in hex system here. :-)

  • @snoopy Did you check (tick) the "version increment" box in ptools? PThat's the only thing I can think of...

  • GH1 Version Display shows ver 1.B .... yes B as in Boy

    I purchased this camera online, it's a new body and has been hacked by the last owner. I went to use simple B settings to match my other 2 GH1s and the camera would only flash me the Wait screen before going to display the image that was on the card. So I went back into ptools and redid it again, double checking I hit the version increment, version compare, new body etc etc. Same thing, flash the Wait screen and then view the image. I checked the version in the menu and found it to be ver 1.B..... yes in Boy.....not a numerical value but an alpha character. So I tried renaming the update 1CC, 200, 500, 1BJ and nothing. It's acting like it's unhackable, again. Any ideas on how to get this camera rehacked and clean up the version number issue ???

    Thanks !!!

  • Hello, im a beginner too, i think this is the right place for my simple question. I use the FM 2.02 and i like it very much, but i don´t wonna have the 100Mbps in the HBR mode, the half is good for me, let´s say about 45-50 Mbps, Question: which changes in the ini file for the Lower Bitrate must i make?. sorry for my bad Englisch. greetings René

  • @tommy Thanks for your interest in Flow Motion v2. This is a comprehensive, full-featured patch that is designed to handle all types of shooting situations. Although I tested it for use with standard Class 10 SD cards, I've been able to successfully use fast Class 6 cards with FM2's 60Mbps 24L, FH, and H video modes. Aside from their bitrates being limited to 60Mbps peak, these modes work exactly the same as Flow Motion's 100Mbps 24H, HBR, FSH, and SH modes, and produce excellent motion picture quality with just a notch tighter compression.

  • After 3 days reading all the posts, I think I am ready to ask a question (Hope I don't get banned after my first participation) Details: Pal area, mostly docs. Tripod, but more often I am running and filming under bad circumstances. I would like one (the) best patch (like most of us I suppose).

    Besides the 'basic' patch settings ( pal -ntsc, iso limit removal etc) my sincere wishes would be:
    • good quality also in low light (45- 50 mb/s)

    • Most fluent motion in 1080p (as I prefer 1080 above 720, and I have read I should not film 1080i

    • extreme stable / reliability (no crash)

    • Preferable compatible with class 6 cards (in case I would run out of class 10 cards, and I would not be able to film at all).

    • (preferable steady, but I suppose no patch can help me with that ;-)

    I found Flow motion v2.02 and my questions are (to everyone who can answer them) :

    • Can I just lower the bitrates in the Flow Motion @LPowell settings? Or will the whole idea of the 'flow motion' be gone, or worse, will there be other possible errors)? Or would you suggest to only lower the bitrate of (for example) 1080i, so in case I would only have class 6 cards I can always shoot 1080i.

    • Besides Flow motion, do I need to use other patches (for the other wishes, as filming in low light)? If that is the case, I haven't figured out yet how to combine patches.)

    • Other suggestions are welcome ( perhaps an adaptation of Sanity 4.1 @Ralph_B or Cluster v6 @Driftwood ?)

    It's all quite complex Thanks you all!

  • @balazer : I figured out where the problem came from : it was the H264 (.mp4) compression that caused banding. When I compress the footage using .mov H264, it's okay.

  • thanks @balazar, to sum it up; things are the same as they were a few months ago in regards to the GH2 hack, there are no plans to update the Settings Vault with the many new patches have been created so it is just a matter of searching them out and testing.
