I finished preliminary decryptor and unpacker for GH2 today.

Vitaliy is a genius!! this is all very interesting (google traductor)

the encryption covers every aspect of the firmware. The firmware "updates" are encrypted so that you cannot see the contents in an understandable and editable form, which means that we cannot "hack" it. The original GH1 hack was do-able because the firmware update was not encrypted. The firmware on the cameras themselves is not encrypted but there was no way to get the firmware out of the camera until VK's GH2 went to have the chip containing the code removed where we can offload the contents directly from the chip itself.

I'm interested in seeing what is happening with the different HDMI outputs. I've noticed that during liveview, that if you press LCD/VF button that the output on the HDMI port changes in saturation, gamma and sharpness(NR?). This looks different than if you press record, which gives us 3 different ways the HDMI output is different under different circumstances. This doesn't even get into the fact that while in liveview there is no red channel smearing on the HDMI output yet when recording there is.

I don't understand why panny has so many different routines for HDMI output.

Blowup, it's too early to say, V. has to do a lot of ground work first, and it's very important to be careful with changes that could potentially brick (kill) a camera. Just be patient, V. is a pro.

>How much more patience should I have?

What do you mean?
It won't be instant.
I expect to make working decryptor and unpacker tomorrow.
After this I'll move to slow and careful reversing.
As soon as test body will be available I'll start making first simple patches (testing version change, firmware u[loading and similar things).

Maybe,because Lola wants it ? ;-) ....

I may be missing the point of the 7D shot music video above. care to elaborate what that has to do with the GH2 encryption? Is it in regards to getting 10bit out of HDMI? Also, I donated!

Hey Vitaliy,
I made a small donation. Hope you can figure a great hack for the already wonderful GH2!
I actually don't understand a word of what you guys are talking about the codes and all but for the reactions it seems to be good stuff!
Actually, what I would love to have is 1080p60, even if it has a time limit or something to ensure the processors safety, 30p (and 25p for the Euro pals) I believe is something we can take for granted!! You'll surely make it happen... Maybe it would be possible to have even more overcrancked options at 720p, who knows??
Can'thardly wait for your hack!
Cheers from Brazil. Come and visit to relax after you pull this out!
You are the best man!

I'm working with my GH2 and the nanoflash recorder, and can´t find any artifacts on the footage with nanoflash. I record I-frame, 100Mbps. The signal is sent @ 1080 50i to nanoflash that detects it and work great. Of course I'm looking forward to see the results of Vitality.

>> Hoping there is something in there that would allow genlock / sync between two cameras for a 3D rig.

Big +1 (but you already knew that V. : ). Ability to match exposure params etc. would be nice too, but frame sync is the big one.

Is it possible to get 10-bit video through HDMI? Currently, it most definitely is not 10-bit and bands like crazy, making HDMI recording kind of pointless. It looks like the internal processing is all 8-bit, but with no dithering. Any way to bypass the internal processing to just get raw image out the HDMI would be amazing.

That was the best "making of" I've ever seen....
