Beginners: Basic hacks questions

belfryman

Starting this for people who have something to ask they feel is too dumb to ask in a complicated thread where you know you really should know the answer so don't ask!

Here is a super useful thread for a guide to setting up stable settings.

Me 2, so i use just 1080i/50 for now ...

belfryman

Cool. Not just me then!

belfryman

Also...what is ExTele? Is that enabling the HDMI port to use for external recording?

belfryman

And...! When I have a monitor connected to the HDMI port I lose the ability to select 1080i or 720p and it records 1080i. Saw there is a video out setting which I have set to auto and wonder if that determines the way it's recorded in the camera rather than just the way it's sent to the monitor.

@belfryman
ExTele is a feature it "doubles" your focal length, similar to digital zoom but not loosing quality,
as it crops directly from sensor keeping resolution.

HDMI it determines capability of your monitor or TV (or recorder)
if you shoot 1080i but your TV is not FULL HD than output i converted to 720,
it does not matter on your footage.

belfryman

Cool, thank you. Glad I set up the topic!
Ex Tele sounds great.
Is that odd that I lose the ability to select 1080i or 720p for recording after I connect a monitor and it just automatically selects 1080i?

belfryman

Also very glad you were reading! Thanks again, for the torch in the dark!

feha

I think you must select before as camera detects monitor than detected resolution will be lockt.
I suppose it is a normal procedure ...

B3Guy

Just to expand on ExTele, If I understand correctly, it records from the center of the sensor, pixel-for-pixel (1:1) in full HD, 16:9. Result? No Moir and significantly minimized rolling shutter :)

Obviously, digital "grain" will be bigger, and from my experience, it is not always as "sharp" as a result.

As far as 25p goes - there is an 'Evita' thread here:

http://www.personal-view.com/talks/discussion/391/25p-official-topic-aka-dont-cry-for-me-argentina#Item_86

belfryman

Sorry, just meant 1080p, rather than 25p, have done my crying already. So assume people discussing 1080 50p.

Question for Ptools users on Mac with Wine: Where are the Ptools settings files stored (e.g., seta.ini)?

v10tdi

Disregard my question. I found the answer.

I had used Winebottler to create a prefix. The Settings files were buried in the Users directory:
\\Library\Application Support\Wine\Prefixes\\drive_c\winebottler\*.ini

Does the hack include support for mjpeg @ 24p 1080 or 720?

Vitaliy_Kiselev

>Does the hack include support for mjpeg @ 24p 1080 or 720?

No.

eyeBOX

@Vitaliy_Kiselev:

What does the "720p30-> 720p24" option under mjpeg fps category do? I am interested in shooting in mjpeg mode rather than avchd because my computer is an older powerPC that does not handle mts files so friendly..

Where can I find a beginner's guide to hacking the gh2?

Thank you in advance and for your hard work..

@eyeBOX

from PTools topic....

Noob Version / fool proof.
1.is your battery fully charged? ok mount camera on your pc. (use the provided cable)
2, Run Ptools and load the firmware GH2 1.0E that you downloaded (looks like GH2__V10 after unziping)
3. Now you have options... just check the first box for version increment and then under Patches for end users ... click on avchd compression and from that drop down check all of 4 options there while your at it. when you highlight each option it literally pops up and tells you type in this number instead of current number. it tells... you.. what to type in. type in that number for each of these 4 options.
4.SAVE firmware. use same file name as original except change the last digit to anything else.
5.Drag or copy and paste or w.e you want, you're new firmware that you made over to camera's card patiently waiting for you grow some balls, now unplug and restart that camera once its on the card.
6. Once camera is back on, wait a second and push play/preview button. it asks you, would you like to update? hit yes!! DO NOT touch anything or mess with camera during update, that's the only danger... so press update and watch don't touch and guess what? Hardly a minute later you're set

belfryman

@feha

The odd thing I have is that if I set the camera to 720p before I plug in the monitor it still records at 1080i after I plug in the monitor.

feha

There are two different settings one for recording and one for monitor, they do no relate ...

I have successfully, consistently gotten my MJPEG settings to give me
125megabit/s(~15.5MB/s) peaking to even over 160megabit/s (20MB/s) @ 720P/30FPS
on my Sandisk Extreme III 30MB/s card.
(Example attached)

Yet,
I cannot manage to get even a mere 40megabits/s in AVCHD mode.
I've used every patch there is out there for the GF1.
AVCHD at those higher rates almost always causes a card speed write error.
But why? If I can consistently record upwards of 160 megabit/s in MJPEG?

Is this just that no AVCHD patch has been quite perfected enough...
Perhaps due to the high amount of variables versus MJPEG's number of variables?

I apologize in advance if this is the wrong place for an inquiry of this type.

MrAnthony

@aperturae: It seems to me that AVCHD is very processor intensive to create and while the camera should have ASICs to do this, the write speed error may be to the buffer in the camera not being emptied quickly enough by the ASICs or even that the camera cannot handle the intensive processing needs of creating an AVCHD conversion from the RAW signal AND writing to the SD card simultaneously.

OSGondar

@belfryman thanks for giving me credit on my instructions "Noob Version / fool proof" =(, out of context the whole grow some balls step seems really strange on here to post it that way! I would have reworded on request, It was for a particular user guys! i'm not just mean in general, i promise.

kool

why nikon can do the mjpeg 24fps?

No_SuRReNDeR

OK here's a stupid question but I was wondering , if you raise the bit-rates/hack etc...will the camera's potentially overheat like the other DSLR's do?

Aria

I know it sounds crazy, but wouldn't higher bitrate use less compression thus less strain on Processor?

belfryman

@OSGondar
There's never a bad time to grow balls, gender dependent I guess! I didn't read through it I'm afraid, just knew I'd seen something useful. Didn't include the how much time you've been wasting bit!

belfryman

@feha
I know I'm being dumb here, hence the topic! but I set the 720p as normal in the menu. I have the monitor out set to auto, but when I connect the monitor the record setting option greys out and becomes inaccessible. I need to test if I set the monitor out to 720p rather than auto if that would over ride whatever I've set as recording format, I know it makes no sense, that the monitor out would dictate the recording format but that's what seems to be happening. Someone bringing non-hacked GH2 round tomorrow to see what happens with theirs when I plug in monitor.

eyeBOX

belfryman,
Thanks for the noob proof instructions.. anyone have an idea of what the "720p30-> 720p24" option under mjpeg fps category does?

belfryman

@eyeBOX
Hi, they were kindly written by OSGondar and testicle enhancement was out of context! Wouldn't 30->24 just mean that? Changes the 30 frames per second to 24, though there is obviously the cinema mode available that is 24 fps?

pchristoph

Hi guys. I've been patching my hacked GH13 for a year and now I've hacked the GH2...but something's gone wrong. I installed 1.0E firmware to camera without checking anything. Left the name GH2__V10. This would be my 'base' firmware.
Then I waited for some testers to make something stable. Vitaliy came out with 3.61 patch that looked stable and I decided to install it, checking off version increment and the few settings 'hints' he recommended. I successfully loaded it up, saved it as GH2__V11.bin and put it on my GH2. So far so good...then I saw Kae's 3 GOP patch and decided to give it a try. THIS is where things went weird.
I can't re-install original firmware?? So then I looked at my menu Version Disp. and it still reads Body Firmware 1.0??? Shouldn't it say 0.0? On my GH1 every time I loaded up a patch my Body Firmware would say 0.0 - so I could revert back to the original firmware and load up a new patch.
So what can I do? Any ideas? I feel like a noob, but I'm not.

UPDATE : Discovery...Seems I cannot go 'back' to original firmware but I can go 'forward' to each new firmware I name. This means that if you want the original 1.0E firmware again, just load the GH2__V10.bin into ptool and don't check anything, but save it as latest firmware increment. This is different than GH13 as you could always load original firmware back to camera (1.32) Works for me. Hope this can helps anyone else.

Ulisse

"... but save it as latest firmware increment."
Version increment must be cecked.

belfryman

@pchristoph
I had a few times when the camera didn't see the firmware on the card when i pressed the play button but not so many, sounds unlucky.

belfryman

@feha
it is weird, I've just tried connecting two different monitors and it's the same with both. As soon as I plug in a monitor whatever record mode I set previously I can only record 1080i and it seems it doesn't matter what I set the HDMI to either, whether it's auto, 1080 or 720 I always record 1080i. If I just plug in an HDMI cable with no monitor on the other end I'm still able to select my record mode, if I connect the other end to a monitor the rec mode option is greyed out and I record 1080i. Weird.

feha

@belfryman

Sorry I can not explain the reason, has anyone tried if it is same on un-hacked GH2 ?

Vitaliy_Kiselev

@belfryman
This is all known for long.
And please, do not crosspost.

belfryman

@Vitaliy
OK, not known for long to me hence the question. Does this only occur with the hack, didn't notice it before? Thanks for the great work.

Vitaliy_Kiselev

@belfryman
Of course it is not related to hack in any way. :-)

belfryman

@Vitaliy
Brilliant, thanks.

Summit seems to be working, after a few tests and is there any sign of a proper [GUIDE - GH2 Hack - From Flashing to Camera Operation] on at least the basic findings? (PS donated, and will donate more soon). So to fellow noobs Elecard Streameye Slim reports this when you hit the 'i' button using kae's setb.ini file. Plus No record crashing on transcend 32gig type 10 cards.

No_SuRReNDeR

Do/can the hack effect the the photo modes in any way?

I actually like the HYBRID factor of my GH2 and although I am a filmmaker I am getting back into photography because of this.

RickPick

I have seen some posts in other threads which recommend saving different versions of the firmware (both original and hacked) onto separate SD cards to enable easily switching from one to another. But does this work? From what I understand the version increment must always be checked. Doesn't this mean that I cannot go back to a previous version without recreating it in ptools? Can anyone clarify this for me? Thanks.

kanintesova

Me too, not sure about this increment thing!

I have been doing this:

first patch applied: increment checked; value 1, saved file to GH2_11.bin...

Cam still says ver. 1.0. but patch applied.

second patch: increment checked, value 2, saved file to GH2_12.bin

Cam says version is 1.1.

So now I am gonna try KAE's file. Increment checked, value 3, saved file to GH2_13.bin

Cam updates but still says version 1.1... Haven't tested yet or checked bitrate. But I am wondering: Is this the way to go? I don't feel so confident. :/

Someone PLEASE shed some light on this. I understand it is in HEX but I don't speak hex - hence I am not a hacker but a patcher... He he.

Thanks!

Vitaliy_Kiselev

@kanintesova
Please read hints :-) Always use 1 for increment.

kanintesova

@vitaliy

Thanks! But I think the hint is a bit ambigious (could mean two things). I thought it meant that EACH increment should increase by one (1) everytime you apply new patch; like: 1,2,3,4 and so on.

So it should always say value 1 (never change that?) Sorry for being stupid.

Anyhow. I just tried KAEs patch and I used "3" as the increment number. It seems to work anyway. Streamparser topped out at 6.352.000 for I-frame. at 24H (trees and stuff)...

edit: bits of course ;)

Vitaliy_Kiselev

>Thanks! But I think the hint is a bit ambigious

?
"Enter same increment each time. One is normally enough."

telkitachki

Could somebody tell me about GH1 patch settings - Encoder settings1/2/3, constant 6000 and Framerate related comparison. Just basic things about result of tweaking this settings. Thank you.

kanintesova

I have weird logic I think. :P

wangc

GH2 kack:"30min limit removal" must be checked?

i mean...does panasonic use the same firmware for GH2 for different country??
in other country which has no this kind laws,,does GH2 use a firmware that has no this limit?

Vitaliy_Kiselev

@wangc

I already answered this - read hint.
This patch is useful for Europian PAL cameras only.

wangc

yes, thanks,I read the hint.
I bought my GH2 in HongKong,So I don't need to check this patch.?

Howdy, Stranger!
