GH1 firmware research volunteers required

RE: P.S. As always, no one can quarantee that you camera will work after this :)

Hi, i'm VERY new to this. I just bought a GH1 with serial number WE0B. If I install the new firmware can I return it to the factory settings if the camera does not work for some reason? Thanks in advance! cjag

Yes.

If the camera does not work after this can it be reset so it 'works' again, at least to the factory settings? (I am totally new to this having purchased a Feb '10 GH1)

If the camera does not work then there is something else going on outside of the hack.. But I would not worry about it not working. If the hack doesn't work right for you ...then you can always revert back to its factory settings.
 
simulate manual focus ring movement (GH1)

simulate manual focus ring movement (GH1)

Hi there.

I started to make some experiences with old adapted lenses. So I have to focus manually.

Is there a way to simulate a focus ring movement in manual focus modus by pressing the FN key?
(I.E. programm the FN key to anable focus zoom for some seconds or till shutter pressed?)

I'd like to zoom in a bit before shooting the photo.

Thanks
Lars
 
menu=shoot w/o lens=on + dial to "MF" + (left arrow key) -> select position of focusing -> (set) -> focus maually.
BUT THAT REQUEST ARE OFFTOPIC FOR CURRENT THREAD !!!

Hello Vitaliy,
I would only humbly add that all what I said in my previous post #2953
regarding the GF1 firmware 1.23
is obviously, still valid for GH1 firmware 1.33.

So if you would consider to give a look to these 1.x3 firmware files
I think that all the Gx1 users will be interested...
(I have checked and the files are still available for download)

Thanks for the attention. :)
 
Jpeg photo has 4/1 CompressedBitsPerPixel and jpeg from mjpeg video has 2/1 CompressedBitsPerPixel (JPEGsnoop), can we change this parameter?
 
All Information from JPEGsnoop.

CompressedBitsPerPixel is Color depth after compression

For example
Standart 0,0,0,0 Noise Reduction off

Photo 1920x1080 Normal quality File size 920 kb

[CompressedBitsPerPixel ] = 4/1
[SceneCaptureType ] = Standard
[GainControl ] = 2
[Contrast ] = 0
[Saturation ] = 0
[Sharpness ] = 0


Photo 1920x1080 Low quality File size 322 kb!

[CompressedBitsPerPixel ] = 2/1
[SceneCaptureType ] = Standard
[GainControl ] = 2
[Contrast ] = 0
[Saturation ] = 0
[Sharpness ] = 0

MJPEG Video 1280x720 (Q400,300,250,188 T4,4,4,4) 4:2:2 checked File size 555 kb!

[CompressedBitsPerPixel ] = 2/1
[SceneCaptureType ] = Standard
[GainControl ] = 0
[Contrast ] = 0
[Saturation ] = 0
[Sharpness ] = 0

As you can see "Photo 1920x1080 Low quality" much better than frame from video but file size more smaller.

And one thing, I set all standart 0,0,0,0 but JPEGsnoop showing "GainControl 2" on photo stills
 
There's an interesting interview with Panasonic engineers about their auto-focus technology, specifically about the speed improvements they got with the GH2.

The Google translation is almost incomprehensible, but apparently the GH2 has a 120fps sensor mode that's used during auto-focus.

possible 50fps with GF 1

possible 50fps with GF 1

hi there,
i was just wondering if it is possible to get my gf1 film with 50fps like the gh1 (slowmo)?!

thnx

"Wrong file name, camera won't be able to read such file."

Unfortunately, with version 3.50d I still use for my GH1 files, I get this message, even though the file name I enter in the Save firmware image dialog IS correct.

It turns out saving is blocked if the ORIGINAL firmware loaded does not have an "acceptable" name. Why is that?

I have a number of Firmware files with short descriptions appended to their original (acceptable) names.

I aslo want to save changed firmware files with short description extensions, too, but I cannot accomplish this immediately IF I start with GH1__132.bin as input and not at all if I use a firmware file with a description in its filename.

I would like a more convenient firmware handling by PTool as follows:
- accept any firmware file filename, just judge the file by its actual contents
- accept any filename to save the changed filename with
- show a message based on the version increment number saying with which filename the changed firmware file should be saved to the SD card for the camera to accept it.
 
hi newbie here

would MJPEG setting that work with GF1 then work on the G2? , I dont get much success on the G2, on my GH13 and GF13 they work with little freeze. But on G2 some setting wont even let me record. also 4:2:2 bottom have of footage always muddy??

Thx
 
Hello newbie here also :)

I want to ask something.
I am sorry my English is very little , still learning.

I will buy a GH-1
I saw that forum about haching GH-1
And i watched videos.
Really great , amazing.

But i couldnt understand how should i make it?
I read this forum but hard to understand sometimes because us language.

Can someone tell me how i hack this step by step ? And also like me for other people.

I have ptool thats all :)
 
seriously though.. buy a gh2. The gh1 has issues in low light and the gh2 is just a better cam.. even unhacked.. and when hacked it will be even better then better.
 
Vitaliy could I ask if there has been any progress in pulling the 720p crop of the 1080p FHD mode into the centre as was talked about some time ago?
I'm interested in this to see if it could allow significantly better use of C-Mount lenses on a GH1?

Thanks for your time

Right now, no.
But I have high hopes after databases will go public.
