GH1 firmware research volunteers required

PTool updated without version change.

Added sensor 3-8 modes adjustments.

Note.
Here I try to describe why this patches can be risky and why we need to test them.

We are patching sensor setup function. Normally it is called upon each mode change.
Some of this modes is default liveview mode (must be 60fps), I believe it is 0 mode not included in patches list. But it can be also 3-5 modes. Worst part that they can be used for MJPEG.

Maybe risky patches should be tested first by one tester only. This way, only one camera may brick, and money can be collected in order to buy a new one for that tester.

Just write here before you start testing particular sensor patch (1920 patches must be pretty safe anyway).
 
MJPEG 1080p

MJPEG 1080p

A friendly question, so please don't :kali:

I cannot find anywhere on the thread what the MPEG Encoder buffer and width should be to give me working 1080p in MJPEG mode?

Also does it run for only a few seconds or is it good for a few minutes? Please can someone post either here or in the sticky the best settings to use for MJPEG 1080p?
 
First page... 2nd post (for testers). Tester13 frequently updates those two posts and you should check their frequently for answers to many questions.

Tester how to do change in these modes? Please write some example. Thanks.

Just look at help hints for codes. Patch change one mode (3rd for example to 7th) to other. I suggest to change code to 7 at first.
You can apply multiple patches to save time (and increase risk :) ).
 
Thank you!

So this applies to 24p as well as 30p?

1.2) How-to get working 1920p30 (most probably upscaled 1280):
MJPEG 1280p width - input 1920
MJPEG 1280p height - input 1080
MJPEG 1280p Encoder width - input 2096
MJPEG 1280p Encoder buffer - input 4821120

Set sensor mode 7 AND encoding settings (above) for best results?

It is frame encoder settings, so framerate have no meaning here.

I don't know that you mean under "set sensor mode to 7".
As in latest version have Sensor Mode 3 - Sensor Mode 8 patches.
And this is all risky unetsted patches, with goal to find MJPEG mode.
 
Thanks tester13!

'Sensor mode 7 is 1920 23.97fps' in PTool notes.

So if I understand correctly (I need to before doing meaningful tests) MJPEG 1280m width and MJPEG 1280m height just scale 720p to 1080p, whilst sensor mode is true 1080p from sensor?

If sensor mode is in 720p, MJPEG width & height just scale the image artificially, no gain in resolution right?

Can you say clearly what the difference is between the sensor mode settings 3 - 8 and how these work alongside the MJPEG width / height / encoder buffer settings?

What are people's best results with MJPEG 1920x1080p in terms of run-time, more than 1 minute? Or just a few seconds? Does it crash playback mode like 24p native AVCHD?

Very interesting thing.

When you recording in AVCHD mode - TV out show brown color screen. :)

What do you mean by this, NURBS? Is it just a flat brown color, or a brown tinted video output of the footage you are shooting?
 
here is a small test clip of the sensor patch (7) 24p with slow pans .. i dont see skipped frames but, to me the image quality takes a hit, i see artifactscreen while recording in this mode...thanks tester for your hard work!

srry for not posting that info, i checked the following version change ,third party battery,mpeg encoder 30p to 24p,mpeg sensor mode (entered 7),1280m width 1920,1280m height 1080,encoder width2096,encoder height 4821120

i hope i tested for the right settings

Important request.

I want to remind you that we need tools to move forward at good pace.

First tool.
Small utility with good interface with ability to view firmware image and find icons and other images inside (visually showing images and offsets).
It do not requare any special knowledge, just C/C++.

Second.
We really need Panasonic compilers. They are available as parts of AM3 (MN103S) boards.
So, if you work on any electronics related company you can order this items.

Third.
Panasonic service software can be very helpful.
Go and ask your service center is they have it.
Most of the service software leaks are made exactly this simple way.
We are not intended to make it public.
So, if you want to provide it and remain anonymous you can be sure that it'll be used for development only.

I would make it a point to reiterate the fact that when it comes to what certain settings may or may not be actually doing (for instance the sensor settings)... Tester13 may not even be the best person to ask directly because he's looking for those here to methodically test these different settings and help extrapolate what these settings are doing based on the footage. That is the whole point of this thread, to carefuly test things and report back... as appose to him releasing a new patch and having to figure for himself and explain to us what it's doing.

That being said... if people want to start comparing real resolution vs fake in the possible sensor modes... might I suggest we start getting a bit more technical and shoot things like resolution charts to look for differences. Shooting plant life is great.. but if your simply looking for differences in fidelity between footage.. it's much more straighforward to look at the lines on a test chart. If anything.. I should know within a couple day if I'm exchanging my GH1 or not and either way will be able to contribute to testing myself shortly thenafter.

Here's a link to the kind of chart I mean, for those who are unsure....

I looked up the service center, looks like there's only one authorized in the US.

Who feels lucky enough to call. :happy:

Might have better luck with Europe.
