I just got a used GF2 for some DIY projects and want try my luck in firmware manipulation. I want to start with some simple string changes or hiding GUI elements. Is this somehow possible with ptool and if not where whould I learn how to do this? The "Developer stuff" in the faq looks like a good start but I can't access any links in that section.

Best regards, Franz

I just did 2x on some basic settings, AQ4, and default GOP 15. The video bitrate was set up 32Mbps, and the result was 33Mbps.

Hopefully we can start polishing it.

I owned a GF2 since 2012 and bought a used GX1 recently for video shooting.

I hacked my GF2 with settings with over 100 Mbps in MP4 and the gear worked well with my Sandisk 45m/s card (U-1) Then I hacked the GX1 with the same setting (for example, driftwood's MOON T9) and used the same Sandisk 45 m/s card. Surprisingly GX1 always showed writing error due to card speed, which never happened with my GF2! I tried several lower mbps settings at around 60-70 mbps with my GX1, no writing error came up, but the video became very unsmooth when played in my computer. The unsmooth playback is obviously caused by the insufficient writing speed during recording.

Quite confused that GX1, a camera supporting SDXC U1 card, could have insufficient wrting speed problem which never happens with GF2, an older model without SDXC card support.

I know GX1 is not a gear metioned often here, but I still would like to know any GX1 owner or any expert ( like @Vitality_Kiselev or @Driftwood :)) could help with it.

BTW, this is my first post and I would like to take the chance to thank every setting provider like @Vitality_Kiselev , @Driftwood for bringing my GF2 to a new level of videography. I have so much fun with it!!!

Thank you!

My question is: how do the hacked G-series cameras compare in terms of the best stable video quality available? I'm guessing, based on what I've read, that it's something like this:

GH2 > GH1 > GF2 > G2 > GF1.

Is that correct?

I have formatted the SD before and afterwards and have tried every option I can think of (downloaded new PTools, used a variety of different digits V20 etc) and no closer after several nights of trying to figure this out

Im using an 16 gb Sandisk SDHC class 10 card

I have searched high and low for anyone with a similar GF2 issue in these forums to no avail. Apologies in advance if I have posted this in the wrong place. But any help or direction would be much appreciated!

As I know, it is impossible to restore the device without disassembling the memory chips. I need your advices.

1. Which is the chip?
2. How to extract the part of the firmware, which is necessary for programming the chip by the programmer device?

Please do not offer me contact the service center. This is my decision and I recognize my responsibility.

I'd love to add a GF2 to my GH2. Any hacked sample footage would really be helpful in making that decission.

Thanks to everyone in advance for this. I am sure I am not the only one who'd love to see some tests.

ISSUE DESCRIPTION: When switching on the GF2, within <1sec an error message appears "Schalten Sie die Kamera aus und und wieder ein" = "Switch camera off and on again".

WHAT I HAVE DONE SO FAR: I have switched the camera off/on multiple times. I have removed the (still fully loaded) battery. I have removed battery + SD card. I have removed the lens. I have tried with another lens. I have tried with another SD card. I have tried with another battery (fully loaded). Not successful. Still the very same error message comes up.

WHAT DOES WORK: The connection to the PC/Mac via USB still works, I can access the SD card.

SIDE NOTE: I wanted to change the firmware to the original GF2_V11.bin or any other; but the camera does not access at all the SD card allowing me to change the firmware. The error message comes up within <1sec.

QUESTIONS: => Is there any knowledge how to overcome this error message? => Is there any hidden trick like pressing a button when being switched on to factory reset the GF2?

Many thanks, Torsten

I've searched for answers but came up with nothing, if there is an answer please point me in the right direction and close this thread. Forgive me if I'm posting this in the wrong category.

I'm using the GF2 (hacked) for filming with old vintage lenses. I mainly use a Canon FD 50 mm 1,4 and a Canon FD 28 mm f2,8. When I try to shoot wide open the image gets all blown out (of course) and a ND-filter would help me with that. But when I shoot in any of the My colour modes the image is fine.

So what does the My colour mode (except the obvious effects) do that I can't do in manual mode? I know there's no manual controls when recording video so does it really matter what mode I shoot in? I'm thinking that the custom My colour mode (without changing any settings to the colour) is cheaper than a variable ND-filter, if the mode doesn't do something wierd with my video...

I got a Panasonic GF2 and have some trouble with the analog video output. I want to use the output to preview video during recording. I already found that you can enable the live output by pressing Q.MENU for some seconds. This works fine for capturing stilts, but if you start recording a video, the output shows only black as long as you record the video. After stopping recording, you have normal output again.

I think this is just a firmware restriction that can be removed! Any suggestions?

And I really need the analog output all the time, because I want to operate the camera remotecontrolled and get the preview via an analog video transmitter.

I don't see many people on the forum having hardware issues so i assume all's good with everyone else.

Currently I have an older Nikon DSLR which lacks video, as next month I'm starting a year long film course I have a need for a new camera which does video well (also will be using it for various personal projects too: short films, music videos, web series, etc.. and hopefully even a paying job or two).

It seems to me at first the obvious choice would be the previous model from the GH2 so thus get the GH1 secondhand on eBay, but the GF1 & GF2 also appear to be attractive options?

Made a comparison of what I know so far about GF1/GF2 vs GH1.

Pros:

a) does "comparable" video to the GH1 (I think it is the same? But struggling to find this out for sure)

b) goes for about half the price as the GH1 on eBay, which is a very compelling point for me at the moment (oddly the GF2 & GF1 are both going for about the same price on eBay??)

c) is exactly the same system and brand as the GH series, thus my future acquired knowledge/lenses/accessories will be very easily transferable when I get a GH2 or GH3 (or GH4? haha)

d) smaller bodies, for extra stealth should I wish for it as they're almost nearing compact size

e) the GF1 & GF2 are also hacked (thanks @Vitaliy_Kiselev! I'm amazed by how much you've contributed to this field)

f) the GF2 uses the same spare batteries as the GH2 (although I think the GF2 does not have the same degree of manual control in video as the GF1 has?)

Cons:

a) lacks a view finder

b) lacks an adjustable rear screen

Any extra advice or information about a hacked GH1 vs GF2 vs GF1 would be appreciated, thanks :-)

Sorry about the audio, my phone rang during the shoot.

50 in academy ratio is actually what a 50 on a GH2 would give... Or almost. A GH2 is the same size as academy matted to 1.78:1 (so horizontally and DoF characteristics are the same, but different vertically). Speaking of which... Hitchcock used a 50 almost exclusively in the 50s and 60s, so a 50 on a GH2 is more or less identical to what you'd get in Psycho.

I feel a bit confused...should I get a 50mm or a 25 mm?

My budget is too small for anything except a GF2 or G2. I am in the UK, so will probably be restricted to buying European models. If I buy a new G2, my friend who has an old G2 may be willing to swap it for my new one because he doesn't care about being able to hack his camera. If I get a GF2, I'd probably be on the lookout for a secondhand EVF or other compact solution (angled screen loupe?) to let me frame shots from angles that don't let me see the camera's back.

I hope to be able to do most of my work with the camera without having to own more than one compatible zoom lens (with stabilisation) and one compatible prime lens.

I care more about flexibility & convenience than about whether the camera gives 1080p/1080i. For instance: - ability to use 3rd party batteries - not having a video length limit - low light performance, especially in video mode - ability to get "film-like" video (other than by using low DOF & other such cinematographic techniques), e.g. anamorphic video. - manual control options - ease with which settings can be changed, including transition from video mode to stills mode and back again - ability to frame shots from above rather than behind the camera, using an inexpensive (<£100) add-on if necessary.

On each of these counts, how do the (hacked) GF2 and G2 compare?

I've googled extensively before asking the above, but I'm still uncertain. Please feel free to post relevant links instead of answering my question directly :)
