Please, shoot identical footage with identical settings using still scenes and motion (use tripod) using original video bitrate and simplified video bitrate patches. After this look at clips at low level.
Start with simplified, as this is current firmware.

ok, no problem... I'll shoot tomorrow,'couse I'm going out now...
Love the Cat digging thru the flower pots on the 720 samurai shot.... 
Quick question to Tester or Jobless.
Are these all the tweaks with these setting? or are these being left out (default)?:
MJPEG Size 1280M = Ticked
MJPEG Enco 1280M = Ticked
MJPEG E1 Quality = 400
MJPEG E1 Table = 103
MJPEG E2 Quality = 350
MJPEG E2 Table = 116
MJPEG E3 Quality = 250
MJPEG E3 Table = 120
MJPEG E4 Quality = 200
MJPEG E4 Table = 125

just updated w/ jobless 'd' settings........oh my....
have a shoot tonight---will use AVCHD1080p24 jobless 'd'!!!!
If needed how hard is it to revert to pre-hacked firmware??

Tested AVCHD 60i vs. 24pN, and yes, no question, the chroma is recorded much better in the 24pN mode.
Also tested MJPG vs. AVCHD/pN, using Pappas settings. Resolution looks actually pretty comparable, but there's a disturbing chroma alias that looks very very much like what the Canons do. Question here though is: why did it do that on the Pappas settings, but not on the other settings? Weird.

Also, the chroma is just crazy higher on the newest firmware build. The 1080pN shots were from yesterday, the 1080i and MJPG shots were from today. Nothing changed on the camera at all, the settings are exactly the same, but the colors are far more saturated on today's shots.

I just tested out D setting with native 24fps. Oh man.. IT IS BEAUTIFUL..
Yes, samuri pan in SH mode will cause the camera to stop recording, but when will I ever need to samuri pan? NEVER. It handles just fine when panning faster than normal.
Barry,
Thanks for 60i vs 24fps test shot and avchd vs mjpeg shot. To me this higher bitrate AVCHD at native 24fps with no recording time limit is the winner over 1080p MJPEG with 3 minute limit.

Personally I'm struggling to think of a reason to shoot high bitrate MJPEG as opposed to high bitrate AVCHD (including native 24/25p + playback in camera). Would be good if someone can do a test of both at their optimum settings. As bumkicho mentions though, the file benefits of AVCHD make it a no brainer for me.
I think just aesthetically, it offers something different. It almost looks like HPX3000 footage or Adapter footage versus Straight DSLR video footage if that makes sense.

Yes, it does make sense. I guess you're saying it looks a bit more "film-like"? Could that be approximated later when editing?
Nah, not saying more film-like. Haha. I've long since realized that film is film, digital is digital. Within both realms there are different looks to choose from.
I'm just saying that the AVCHD looks different, to my eye, than the Photo JPEG. I like the look of both, having both wouldn't be harmless.
Dunno what you would do to get the Photo JPEG look out of the AVCHD.

I tried this setting and I'm getting weird splotchy artifacts at 720p as if the bitrate is too low. I just did a test shot of my room right after installing the patched firmware, so my iso was set to 1600. 1080p mode doesn't seem to have these artifacts. Maybe I set one of the parameters wrong?
Here's what I'm talking about: http://dl.dropbox.com/u/1017296/splotch.MTS

They certainly seem to have obvious differences - though from what I'm seeing the higher bit-rate AVCHD holds it together a bit better? Lack of moire and other artifacts.
Add artifacts

Unless I'm crazy... that's what appears to be happening.
I set the camera on the tripod and shot with yesterday's settings. Then I updated the firmware and shot with today's settings. Those shots were taken about 30 seconds apart from each other, but the chroma is hyper-saturated on today's, versus yesterday's. Same camera settings, same white balance, same everything. I left the camera in the mode I'd established for yesterday's shots, and shot. Then I updated the firmware to today's and shot again. No other differences in operation, but the resulting images are quite different.

Hey all,
I've been putsing around DvxUser for some time now. However, I just decided to sign up and really get active since I started getting involved with this firmware hack. I just wanted to add my two cents to what I've discovered.
By the way for anyone who's interested I've been using the C and D settings primarily and I'm really loving my GH1! It's like a new camera.

- Everything I've shot has been beautiful since the hack
- AVCHD seems to be holding up well even upon up-ressing ine AE
- Only issue I've seen is that 24pN (native 24) footage, according to After Effects, is 23.971 frames per second.

I've been testing with the D setting and what's weird is in 720p I can get around 35mb/s with my shutter speed at about 1/200 if I shot the same scene ( trees and bush ) with a 1/50 i would only get about 10mb/s and the there isn't enough detail.
