4:2:2 ??? Will it ever end 
. I guess that may have an impact in bandwidth?

GH1 firmware research volunteers required

- Start date
No way. That's insane. I don't understand what ANY of that text means, but getting factual 4:2:2 out of the camera just shoved Photo JPEG into a top slot for some 24P goodness.
Tester-- About the HDMI request, there are specific mode options, but you want to know what the HDMI is changing over to for each photo or video?
The mode options are: 1080i, 720p, 480p
Let me know what to try, video out must come.
I haven't patched the GH1 yet, so here are some results on stock version. GH1 doesn't report anything while in TV Output mode, so info is limited by what TV is showing, which in this case we will call Pana Brevia as only line resolution is reported, not refresh rates.
Regular HDMI playback mode.
1) Pictures, all aspects - 720p.
2) AVCHD FHD - 1080i.
3) AVCHD SHD - 720p
Viera-link on -- everything shows as 720p.
I can run patched tests on a Sony TV later, which does show both resolution and refresh rates.

My congratulations to tester13, nice work has you been doing here, now every time a see a GH1 video in Vimeo is look like was filmed in another old camera.
Now, just hope for the HDMI live view on recording.
I´m making my paperwork for access the use of a coupon of Dollars in my country to make a donation, is a really long and tedious process but this deserved.

ok two questions.
1) 422? really? wtf? really? 422? (ok that was like 5 questions)
2) I live in beirut, I always say this and it screws up my record on the marketplace. I can't use paypal or make transactions online here it's prohibited and verrrrrry insecure. How can I donate? I really want to. I have been living off moneygram/western union for ages, car3o can you receive money that way?
Have loaded 3.36 trying mjpeg, different cards give me different results. can't play back mjpeg in camera. Is 422 up? is it a patch?
I'm sorry I've been holding a lot of questions but i just can't keep it inside anymore I sound like an excited 6 year old.
The footage is bomb.

Also, I've noticed something, or maybe it's in my head. In mjpeg mode, my cards are lasting longer if I'm tele. When I go wide I get 2 seconds. Also when I'm on the kit lens it 'feels' like it's making my camera do more work. IS makes a difference too I get more with same card same settings same position even on a tripod with IS turned off.
Am I tripping in saying the the kit lens is making the camera do more work cause it's made to interact with it way more than a manually adapted mechanical manual lens? Or are they two completely different processes that don't eat up each other's processing power?
I'm sooooooo sorry if this question is moronic.

Tester13, would it be at all possible to give the MJPEG VGA 4:3 mode a higher bitrate and a frame size of 1440x1080? Some users in PappasArts' thread seemed interested in this as well.
Thanks again for everything.

Yes. Really. Yeah dude. Without doubt. Yup.
Looks like I answered all five.
Patch will be coming, some more testing is required.
You must ask Car3o about this, use PM, please.
It is ok to have playing it back in camera, bitrate is too much.
We'll move to this problem later.

It may be possible.
But we'll need mayor interface and internal engine changes before this.
As we have too man patches and too many newbies.
Haha. I know you're joking, but I agree with what tester said earlier about conspiracies.
What I'm seeing here is MAYBE there's no such thing as crippling. I'd be confident enough to say that Engineers at Panasonic are not crazy, stupid, or anything like that. Consider this: We're all now having to worry more so about what SDHC cards we have to match the compression that we want to get. Well, what does the average consumer do? They go and buy the cheapest and then have issues, blame the camera, not the card.
So, engineers would be creating a massive problem for the BRAND by rolling out a camera like this. Customers would have no one to blame but manufacturer on ignorance, which they are rightfully entitled to.
What Tester here is doing isn't for the average user of the GH1, but for us geeks and filmmakers that want the best for nothing.
It'll be interested to see the response, but I'm happy for what's happened so far and am looking forward to more.
If I had an HDMI TV/Monitor I'd be all over the testing for the Live Out...If Tester13 can figure that one out, there could be a whole lot of 5DMKII and 7D's going on ebay.
Seems like in the last few days amazing progress is made every time I check back here. Amazing work Tester13.
Perhaps if there's nothing else needed to be purchased for the development efforts, we can start looking at getting Tester13 and some of the really active testers some equipment for their GH1 rigs? Lenses, external monitors, etc? If we cannot compensate them with $ we might as well give them everything they need to test with the best quality gear.
Newcomers make sure you donate something, even if it's small... this is an incredible effort.
If you have downloaded the ptool and haven't donated yet, shame on you!! There is no reason the donation account shouldn't be in the 5 figures by now. C'mon guys.

Wide shots contain more detail generally, so there's more information for the camera to handle - easier to get overwhelmed with data.
As for the second part, it's long been speculated (maybe it was even proven?) that the kit lens invokes some special features on the camera end that were causing compression artifacts to show up easier (under the old 17mbps bitrate) than with, say, a 'dumb' Nikon lens mounted to an adapter and working full-manual. So it doesn't surprise me this continues to happen in the enhanced firmware now.

We are going lens way today, just it happened that I don't have any wide lens, plus audio gear for upcoming project can be useful.
I also hope to have special sponsor place in next interface remake. So, if anyone selling some gear want to provide it as donation, we could place his advertisment. This is very effective way to get info to potential customers.
Oh my god I just read that again, forgive me, but this has been received with a lot of excitement here. Thank you so much for all your efforts.
Will pm car3o tonight, Am trying with several brands of card, and several classes, and different amounts of detail to see if there's a pattern to the cut of recording time, or which card works best. I had no trouble with a class 6 16gb, a class 4 1gb (can't believe it) but i bought another brand of class 6 today and nothing lasted more than 5 sec.
Again, thank you so much for your work sir, it's a pleasure to follow this thread, a bit intimidating (in the good way
) but a pleasure. Thank you for my new camera

This is a great idea. Hot Rod Cameras? Zacuto? Redrock Micro? Anyone have good contacts at these companies to see if they might be interested in donating some gear to Tester13?

No, I won't accept anything from Zacuto, Redrock, Hot Rod.
But from smaller and cheaper brands for normal people, yes, we must give them a chance to be more widely known. So, even if you small one man company doing some innovative things, it could be your chance.
