GH1 firmware research volunteers required

[Ben_B]

Change is it general function setting framerates for all AVCHD options (MJPEG have different function with similar goal).

Does that mean that if it's patched successfully there will be no more need to remove pulldown from 1080p footage?

[Vitaliy Kiselev]

Most probably not. It needs much more research.

As for bitrate, I believe that coder have following settings : frame size, reccomended bitrate, hardcoded maximum bitrate setting, and frame rate.
We just don't know if hardware is capable of 720p24 in high bitrate, or any other low level changes are required.
Easy thing is to change frame rate and try to change bitrate slightly to look if it have effect.

the 720p24 mode you've added is very interesting, what I mean is that 17mbps divided by 24 frames will give a quality like 1080p24 at 35mbps, no need to hack the bitrate if it works.

Just trying to get the 720p24 but I downloaded GH1__121.bin from panasonic web and ptool just minutes ago and I got "Access violation" executing it (windows XP), I tried in 2 computers. I doesn't even create an empty file.

[DrBlaz]

to change to 720p24, is it only needed to change 1 byte?

ROM40568B10 mov 0x3C, D1

changed to:

ROM40568B10 mov 0x18, D1


if its correct will try it directly

GOSH- this is feeling very epic, I'm hanging on to every post--PLEASE somebody get Tester13 a GH-1 body!!!!
Hey if we can round up 60 users here with 10 bucks a piece we can get Tester13 a $600 body, (after rebates)

720p24 would be fantastic. MJPEG 24p would be a great addition also.

As I already said, we need reputable guy from this forum to place donation button. I already have domain, and will change name servers to my hosting as soon as it'll be clear.

Access violation was because you did not extracted firmware to same directory.
I changed ptool to v1.26 to add error handling.
Current version now reports that it can't find proper file.

Don't do it and remove addresses from your post, as someone without head can do something.
Use provided bat files and test only if camera recognizes your new binary files and allows you to update.
It is not good to do something stupid.

Since I have not seen the inside of a body, does the unit have a JTAG/UART port or any other form of programming port that might make it easier to try things without needing to do the "firmware update" stuff?

Maybe we could also monitor that port too?

Just a few thoughts.

[DanDOF]

Tester13, could you summarize what you need right now to move forward?

[DrBlaz]

Access violation was because you did not extracted firmware to same directory.
I changed ptool to v1.26 to add error handling.
Current version now reports that it can't find proper file.

it was in the same dir, but anyway the new version worked, used make_fps.bat the patching process was ok, patched 50-60 -> 24..


But when updating to GH1__123.bin , the progress bar reach about 20% and then shows a message " turn the camera off and on again" , the firmware version 1.0 remains unchanged, tryed several times.


BTW the batt must be full or the NO VALID IMAGE msg will appear.

Hey there. I don't know if this will stick, but I created a donate page for Tester. I've been here 5 years and pretty known throughout the boards so if you guys feel comfortable, send him some worthy donations. Before someone says something, I tried to donate money, but apparently you can't donate money to your own account. If someone else wants to do it, feel free. The more we have contributing to this process, the better off all the Gh1 users are.

Please, get donation button HTML code, make zip file, and send it to me.

I'll make simple page on gh1-hack.info with poll, tonation text and donation button.
