GH1 firmware research volunteers required

• PayPal balance: $551.11 USD

we could maybe get another Gh1 if needed. one for heavy work. unless the Gf1 is necessary.
i'm waiting for a vendor on ebay to come back from vacation to order a G1.

Hey Car30,
Care to share who your vendor is? Seems to be a reliable fellow and maybe I can buy a GH1 body from him too!

[Daniel S.]

Ok, i asked him for high-quality pictures. Lets see if he answers.

Daniel

No answer so far..

[Vitaliy Kiselev]

Maybe we could offer him a Donation for his busticated GH1..i cant imagine it will be easily re assembled by him or a service department?..

what do you reckon, Would this be useful Tester?

No, we don't know state of boards. They can be damaged.

As far as I remember it was cameraland at ebay.

Most people who donated lately did it for GF1 specifically.
And we must honour their requests.

I believe we had a guy in this thread who promized good prices for GF1 and G1.
May be use him, rather than wait?

I donated for GH1, but I understand a GH1 body is on its way to tester13...
Please excuse if this question has been covered before (I dont understand all them technical terms here) but is there any chance of increasing framerates for slo-mo-recording ? (ie 120fps)
Is there also a chance of changing the aspect ratio to 2,35:1 ?

Greetings

You are correct here.

Please excuse if this question has been covered before (I dont understand all them technical terms here) but is there any chance of increasing framerates for slo-mo-recording ? (ie 120fps)

No. Sensor must be redesigned to allow such speed.

Is there also a chance of changing the aspect ratio to 2,35:1 ?

May be. It is very long shot.
Also many parts seem to be coded specifically for 720p and 1080p compression.
It is not that hard to shoot at different aspect ratio, you need semi-transparent sticky tape on screen as guides and later process video using crop filter.

No. Sensor must be redesigned to allow such speed.

What about increasing fps and decreasing resolution ? Would that be possible ?

Thats the way i am doing it now... But this way i am wasting data by cropping. I thought of the framerate benefiting from an different aspect ratio, for example if there was a resolution of 1920x850, could it be recorded at 50 respectively 60 fps ?

Thanks for your quick reply

Me again..

Speaking of which, someone in another thread wondered if gh1 could be modified to raw output in HDD or SDD. Any chance of this being possible ?

Again, please excuse if this was discussed already.

No.
If you want RAW capture buy Canon 7D or Mark II.

No it could not be recorded at 50fps.
All this requires new sensor and new LSI. Or entirely new camera, in other words.

I believe people sometimes concentrate on technical stuff instead of normal ideas, script, lighting and acting.
I am bored to see crap made using many 5D Mark II cameras.

[gemüsesaft]

Of course I concentrate on technical stuff, as i transform the ideas of the script writers into moving images. Those are to be high quality visual entertainment, so I try to understand the technical issues you need to achieve those images. All of this of course low-budget, that is why i am busy following this thread and donating, otherwise I would have bought a RED or a 5dmII or something similar :-)

anyway, thanks for your quick replies, I try hard not to make boring crap with my gh1 :-)

Hi Tester, Sorry to disturb you among your precious research but I am a little confused about the number I have to write in the Ptool for the version change. Now I am using the GH1_1.32.bin.
Thanks for your answer.

[outbreaker]

tester13. Could you give me a help?

I have tried to open GH1 firmware 1.32 with IDA 4.9 Pro. However, I have been not able to open file.

I choose mn103 processor, and fill up "0x04000000" in ROM start address and Loading address.

IDA keeps saying
"You have just loaded a binary file.

IDA Pro can't identify the entry point automatically as
there is no standard of binaries.

Please move to what you think is an entry point
and press "C" to start the autoanalysis."

I pointed address "0x0400000" for entry point, and pressed "C". Nothing happened. I Could see a lot of strings, but no function. There should be something I missed...

Can you help me what I did wrong? I'm new at IDA..

[Rabot]

Throwing such ideas, unfortunately, is useless. As such things are much more complex.

Well, it might make more sense than simply change one value, since I guess the whole thing is used to compress to a 16x9 ratio.

But yeah, I don't know **** aobut that stuff, it simply make more sense that way.
