Excellent stuff, just excellent! Thanks for this post. Extremely helpful even several years later. I want to hack my gh2 with cake 2.
Should I follow this exact process, but use firmware version 1. Or do I still install with firmware 1. I am in fact grateful to the owner of this site who has shared this fantastic piece of writing at here. Thanks Tony. This is my progression and understanding so far.. I have dragged it from the download into a folder that I have named ptool folder.
I then double clicked on this ptool3 icon and it opens and I get a prompt tab message giving me the option to run or cancel. I clicked on run and the PTool v3. For anyone wanting to hack their GH2 following and reading the instructions is key.
I truly believe that this is not hard e. Now following your instruction 3. Downloading the original GH2 Firmware. I just showing my progress and hope it helps anyone who is scared of hacking their GH There is nothing to be scared about just have a go. You can only go forward. Also, WinZip was not properly installed by a user with administartive privilages. Hey Sam or anyone else that can help , once you create a new.
I hacked my gh2 with Flowmotion 2. But I am not sure how to check if IT actually happened…if it actually is now hacked. I thought with the hack it would be like 20min.

Update to above comment — went through the same process on a PC and it all worked fine. Great info. What is an ultra stable patch that shoots at 44mbs?
Thanks bro… that worked! The official GH2 patch is now available! Pingback: GH2 video shooting, any tips? My GH2 firmware updated without any brick-age. Regards Hugh. Thanks very much for this guide, by far the most helpful I have found! A couple of questions: a I have attempted to hack my GH2 and thought I had just about managed it but then when I went to adjust lens, Panasonic 20mm I could not longer adjust f-stop.
Seems to have disappeared from screen… Am I missing something really simple? Thanks in advance. Eh … excuse me, but why would I want to hack my GH2? Okay so the second I stop reading and start tinkering I figure it out. Enjoy your new camera! Hi, great article just one question, do I have to format my SD Card on my mac… to another format?
Much appreciated. Keep up the good work. Do I get the higher bitrate when shooting in iA mode? Or only in 24p Cinema Mode? Many thanks again. Hello, This is my first attempt at a hack…..

Thanks for you kind words! The Flow Motion V2 hack has been kind of a let down. Nice post. The video quality is amazing at p. Just want to thank you for both of your how to hack the gh2—finally I at least prepared a hack file on a mac. Still not sure which hack to use— finding commentary and then finding the download is very frustrating.
I downloaded sanity 5. Still looking for an appropriate hack for studio shooting of science demonstrations—-sometimes with very bright explosive fires and low light levels.
If you have any suggestions let me know. Again — thank you! I kept working at it and found that I had to use the 24fps settings for the uploaded hacks to work.
I have recently been using Driftwood Moon 7 hack and all is stable on 24fps and 50fps it freezes after 5 seconds on HBR 25fps. Now I have found a setting I like I am keeping to that one as your right choosing a setting is not easy. HI, i hacked the camera with the cbrand hack, following your guide. Now i want to hack it with a sanity 5. Do I have to load again the original firmware in ptools, or just the cbrand the one that is in the camera at this moment?
Just got won a auction for this camera as a second body to 5D3 and testing the waters as I might prefer the small form factor. But if I want p at 50 fps I must, right? Quality rivals the 5D … bigtime! Thnx mate, much appreciated. This is a great write up! So I started to try different matrices always with 6 as first number. Then my intuition told me that It would be good idea to use same frequency increase or near same frequency increas in all matrix numbers, and also to use numbers multples of 6 or 3, numbers with a commom denominator.
This new design made the camera very very stable, and finished a problem that previous matrices had.
Before this matrix tweaking the on screen information on the LCD used to be delaied, maybe due to the camera processor being stressed doing image compression. This new matrix desing made the on screen information to be ok, without delay, so I perceived that the camera processor was no more stressed. Also my intuition told me to use same matrix in the intraframe and interframe which saves data for the temporal compression, to get a better texture with same quantization and design in both, and less work for the camera processor.
When I found the best matrix desing I started "The Patch" topic because I was believing I had found something I could keep in the camera and no more firmware changing. But then the iso problem showed up. One matrix design was better for low iso, another for high iso, because lower quantization shows better textures, but cannot handle heavy noise without artifacts.
The fallback idea comes to the mind. The camera uses the fallback tables when the main matrix cannot do a good compression, so it is possible to have two matrices working together. Then I did tests to find which matrix to keep as main and which matrix to keep as fallback, and also with ideas from members I developed different configurations for each recording mode considering theyr datarate and needs.
After this moment I perceived the need of tweaking the Deblocking tables, it works to turn macroblock from compression into a texture, some kind of anti-aliazing, or anti-block. I adjusted it using same theory of multiples of 6 or 3 with common denominator, after doing study about deblocking in other patches and in the original firmware. For my surprize the correct settings in deblocking tables cleaned the diagonal rain pulsing pattern. A gift.
The Denoise patches also was developed from members idea of to have a patch with clean image, so I developed matrices to reduce noise, increasing quantization in first digits and using same numbers to try to flatten the image. Good results in denoise, but without the dct frequency to get good texture. A final tweak was to learn again from flowmotion, moon and denoise, to compare the matrix desing and to create a new matrix and fallback to do everything, good for all isos, with good denoise and good texture, a small increase in quantization in first digits, keeping dct frequence increase, a high quantization in chroma last digits and so on.
I will test this and report back. Did a test now, with the RJ focal reducer, and the Nikon 35mm 1. I am using the stable version, not the high. Only HBR 30p makes me to want to use the high datarate version, 24p and p are just excellent in the stable default version. There is no way to make only HBR to be higher datarate because the settings changes p also, and increasing datarate for p will hurt the stability of the default version.
But this is subtle, in flat surfaces. Comparing the datarates in the recorded videos in the computer, the camera generates less datarate for HBR compared to p, 1,15x less datarate for HBR in same scene. Also HBR pixels and frame rate is more information, 1,x more than p This results in something around 1,3x less datarate per pixel and can explain the small difference in HBR quality.
It seems for iDynamic enabled, with the mm lens, iso is better for less noise, needs more tests. My last post for a while, I did my best and I will keep away again for other tasks: pay attention to the results from this patch, I like the images from it, but in the tests in the the patch topic it is showing the worst results among other patches tested, lots of recompression mud and macroblocking in dark areas, so do your tests before using in a professional work.
Apefos I'm deleting that file. It's not a fair comparison to any patch. I will start a new topic when I confirm I have good repeatable testing for each patch. And again thanks for the patches! Just a final word: I did more shoots to confirm if the image has mud or macroblocking, in high and low iso, and in good and low light, and I could not see significant problems.
So better thing to do is to trust in your own tests instead of other peoples tests. Do your tests yourself. The End patch looks very similar to the image noise and texture from these movies using iso from to when using these tip:.
Keep white balance in K, it shows less chroma noise. All development of the end patch was done using k white balance, this is one secret which makes difference.
What film mode would you recommend using with this patch? My personal gh2 looks nothing like the arri Alexa I use.
I can't even grade the footage to look anything like it. Possibly a superior colorist could grade a screen grab but the dynamic range and dof seems very different along with how the cameras handle motion at the same fps and shutter speed. Any help would be appreciated I've tried almost every patch on this site and a few custom patches from friends. Cinema mode 24p. GH2 camera with a manual lens MD rokkor-X 28mm 2.
Always at 2. Despite the differences in size, all files looks good.
