Switch OFF the AGC... please...!!!!

I'd be interested in helping out...

I added some info about NM103 to my blog.
GH1 firmware can be disassembled without major problems.
You could also note that MN103 is CISC processor, so more easy to understand sometimes.
I believe that bitrate, AGC and batteries check can be found .
Note that processor module source is freely available on request.

Unfortunately, I am sure that GH2 firmware will be encrypted very good (as is TZ7, TZ10 firmwares). Without any hope for dumping and similar things.

[Hunter Hampton]

Cool- Thanks for your effort. So do you mean that the bitrate can be made higher? What about mpeg 720 mode, can that be adjusted to a higher bit rate?

It is really great to hear that the wheels are beginning to roll in regards to reverse engineering the GH1 and getting some very helpful features added. I would see the most important (and feasible) hacks would be attempting to disable AGC and having native 24fps in 1080 & 720.

I unfortunately do not have the knowledge to spearhead anything of this caliber in a technical regard, but...

I do have extensive experience setting up grassroots campaigns for art-house film distribution companies in New York where I live and work. If we could find an engineer with the knowledge or a group of focused people to start working on a small list of hacks, a paypal account could be set up for them (much like the Magic Lantern project) for GH1 owners to donate to the cause. I would be more than willing to set up a small campaign to help spread the word and try to attract people to donate to such a cause. GH1 owners (including myself) are passionate about filmmaking and this camera and I'm certain would be behind a cause like this.

Thanks for getting the wheel rolling tester13!!!

Very interesting thread; will be following it with interest. Wish I could help in some way but all this stuff is way beyond me.

Sorry for going off topic, but could you briefly say if your work on the Pentax camera(s) uncovered any possible enhancements for their video capability -- such as bitrate changes or 24/25 fps frames rates? Are they easier to work on compared to Panasonic?

Thanks.

And I would be more than willing to give a few bucks to this cause!

[greymog]

+1 if this is for real. I'm after bitratess going up.

[Svart]

I'm a GH1 user but I don't have time to offload firmware and decrypt. Do you have the decrypted FW posted somewhere so we(I) can take a look?

[Vitaliy Kiselev]

Legally I can't distribute GH1 firmware.

[MR Fanny]

if you are able to see 60 50 25 and 24 fps does that mean it is possible to unlock those fps for user use? very interesting. I know that when the camera is put together the main board allows the assembler to set region only once then it is locked. can explain why some people get their camera serviced and returned with different region settings if the main board is changed.

[Vitaliy Kiselev]

Yes it'll be possible.

Don't know about region locking other then that it is purely artifical thing for long time.
I believe that 720p 24fps is very interesting indeed.
And if bitrate could be up to 28Mbps, picture will be fantastic.
