vimeo link shows me still muddy in the flowers- I don't see any huge improvements.
I'm thinking vimeo compression here?

yeah it's vimeo. I thought it looked funny myself so I downloaded the real file. The downloaded file looks *much* better.
I find this interesting because some files that are uploaded to vimeo do not exhibit this mud while others do even though the source material looks fine either way. I think vimeo doesn't do an equal job compressing different files that are uploaded to it.

Vimeo is no good
Vimeo is no good
Vimeo is going to suck ass at showing high detail, Vimeo isn't any good. I use it to host the 'original file' and give you a quick peak at the content (maybe you don't think the test I did was any good because the scene wasn't high enough detail. That is why I show the vimeo, it's sort of like a preview)
To get the full effect you must download the original .MTS on the right side of the page at the bottom.
New shot will be up soon too, walking and talking interview style in the woods. Just a new perspective/scene with the same settings, but totally different than the flowers.
Good luck,

Embedded Vimeo clips do not have HD button turned on. When played directly on Vimeo website IQ is much better. For careful examination you would need to download the MTS files as others have suggested.

Your video is the same as myn and jobeless, also 47,92fps reported by MediaInfo.
And as some players (I use ZoomPlayer) play footage at this framerate it can be quite high probability that camera is affected by same problem.
As 720p24 footage (cropped from 1080p24) show good framerate and plays fine in camera.

Holy mother of mercy... I just tried out the D settings, shot in FHD with kit lens at f14 - f/22, 1/50, auto-focus, waving it around like mad.
I just transcoded into prores and put it in FCP. To say the least, I'm nothing short of completely shocked, flabbergasted and amazed. Clean footage, no mud, crisp details, flawless motion blur. My my my my my - today is a good day. I see my GH1 as a completely new camera now.
Thanks to all who made this possible, including everyone who donated & tested, and especially to Tester13

Perhaps this means something, perhaps not - but I've noticed that with native 24p clips out of the gh1 that is imported into final cut pro, FCP lists the field dominance as "Upper (Odd)" even though frame rate is "23.98 fps." For progressive clips in FCP, the field dominance column is typically marked as "None." Field dominance is usually associated with interlaced material.

I patched using the jobless "C" settings. I am not seeing any bitrate increase. Twice I have patched and reset the camera and then shot 90 seconds of hand-held walking-around video only to find the files are only 150-160 MB. That's about 14 mbps. I downloaded the jobless flowers .mts and can see how great it looks and that it has a file size of 108MB for 25 seconds.
Am I missing something?

Avchd is variable codec. You need hi-detailed scene in order to increase the bitrate.
Actually I was experimenting with D setting in low detail scene and I got 9 426 Kbps.
I wanted to see how codec dealing with gradient color banding. It seems that is still there...
I'll post clips leter....
1080 with newest AVCHD patch.
There is no comparision with not-patched firmware but improvement is clearly visible.
Footage is not representative.
Kit lens, ISO 200...ladies and gents I have a brand new GH1-i where "i" stand for improved
I suggest downloading bigger file.

Thanks to tester for his ingenious work and deditation to project.
Bravo!

still seeing slight mud in pavement and lots of rolling shutter (click back and forth frame by frame @ 7:02 on second file).
But the color looks vibrant- great hi's/lows./
This is great progress

Are you using Autofocus? On the big file?
When you zoom in to leaves on wall-- I go frame for frame and every 2 frames or so---the leaves in the shadows/ or BG of the front leaves goes out of focus, in focus, out of focus, etc, etc.
yes, I used autofocus. and maybe also pressed to de-focus while recording.
rolling shutter is different story. overall I am really impressed with result.
Great stuff, IanB! I was a bit underwhelmed by the Vimeo version but the MTS original looks spot-on. I'm going to patch my camera in a few minutes and go shoot some on my own.
One problem - when I load the MTS file into Cineform NeoScene, it rejects the file. Do you know of a way to transcode from MTS to another format like ProRes? When I've got some test footage I'll try FCP's Log and Transfer as well.
can't get firmware to update
can't get firmware to update
so my GH1 has 1.32 already installed from Panasonic. I downloaded the ptool3.exe and moded the 1.32 to increase the AVCHD bitrate and saved the moded firmware as GH1__133.bin, copied it to the SD card but I can't get the camera to update once the SD card is installed. I've tried over and over, even using different version numbers for the moded firmware. nothing works. what am I doing wrong?

Hmm.. I use NeoScene to transcode MTS to cineform avi all the time. It is in window version and it may be different in mac version.
Oh I do too, but Cineform didn't work for me just now on the MTS file IanB uploaded. Wondering if it's something to do with it being from the modified firmware, or just a coincidence or something got messed up on the Vimeo side. It should be identical to the original, but maybe not.
I'm about to patch my camera and go shoot some tests so I'll have other footage to try and will report back.
