Different settings for different cards. If you have at least a class 6 or 10 use the settings from the link I posted. If you have a class 4 use the settings from the first page.

ok went bak to 4000000 and it worked fine ..i wounder y anything over 4000000 is making the video look choppy, it could be my card..anyone know? good question oedipax... one more thing i never experienced the camera stop recording at 60 p ss120 or higher even with very fast pans back and fourth ..(with the first D settings)

Native 24p/25p
Video Buffer 84,000,000
Video Bitrate Adj 60,000,000
Overall Bitrate Adj 56,000,000
Limiting Bitrate Adj 60,000,000
Camera settings: AVCHD FHD
The above settings work perfectly for me using a Transcend 8GB class 10 card, even with insane pans. So getting a card with higher data rate should sort out the write speed problems.

Great to hear. Have you tried this card with mjpeg? I am going to put together a list of all the cards tested and what works with what, so as much info as possible would be great.

great idea,and Issac if you dont mind regarding the mjpeg, can you also keep track if the card allows for play back in camera, my class 4 will allow recording but not play back, im not sure if any had luck playing back mjpeg ..

I'll try MJPEG. TBH things are changing so quickly on here (hourly!) that I'm not sure what the recommended MJPEG settings are
. Will dig around and see...

Here goes - some low light footage. ISO 1600, Nikon 50mm @ f/1.4, 1/50, 1080p24n "D" settings, "Smooth" mode without any changes. Enjoy my dog sniffing around for a place to use the bathroom, some flowers, a fence, and frogs croaking.
Thanks for uploading this. FPN is still there @ 1600 ISO, but not nearly as bad as I remember it. And, I've still got some 800 ISO footage that I looked at and it is surely worse than this under low/no light.
Even on the 7D and 5D I never exceeded 1250 ISO, don't think I'll have to with the GH-1 and fast glass, either.

I tried these settings and I'm still getting splotchy video at 720p60fps. I'm getting these splotches at all ISOs now. I'm also making sure I shoot at a shutter speed of at least 50. The 720p60fps video was fine using the D settings and B settings though.
I tried once with the video buffer checked and once without it and the problem was there both times. I'm not using any other parameters other than the third party battery, version change, and native 24p.
I'll post the video again to show what I mean: http://dl.dropbox.com/u/1017296/splotch.MTS
Is anyone else getting this problem or is it just me?

Your shutter speed must be 60 or faster ( 100, 125, etc)
If you put shutter at 50, Gh1 duplicate frames and create problems for codec with these settings.
As for shooting 720 60p you should use shutter speed 125 for nicer motion blur regardless of settings you use. (even with original firmware)

I really believe it has to do with the types of cards. Everyone should post what card they're using, like the EXACT model, and their settings. Isaac, I have a list of settings already written down if you want to PM me what you have, or I'll PM you. I even had a thread in the Gh1 forum for this already, but nobody posted.

You'll likely see MJPEG settings are in the MJPEG thread.
I was shooting 50 shutter last night with no problems. I'll try again today using the hedges of codec death.

I did a few tests with the high bitrate AVCHD patches. ptool3 settings were:
Native 24p/25p
Video Buffer 84,000,000
Video Bitrate Adj 60,000,000
Overall Bitrate Adj 56,000,000
Limiting Bitrate Adj 60,000,000
Camera settings: AVCHD FHD
I like to take a still shot before video so I can recall the camera settings later. This test was to see how much noise there was at ISO1600 in a typical indoor situation. The camera settings were:
exposure: 1/50sec
Focal Length: 54mm
Aperture: f/5.6
ISO: 1600
This was with the 14-140mm lens - complete with polarising filter I recall.
I'm in the UK so the video frame rate is my preferred 25f/sec.
Still image (warning - large!)
Video (approx. 84MB)
According to quicktime, the bitrate was 42.34 Mbit/sec.
The next video was with the 20mm f/1.7 lens.
Exposure: 1/50sec
Focal Length: 20mm
Aperture: f/4.5
ISO: 1600
Still image
Video (approx. 70MB)
According to quicktime, the bitrate was 28.93Mbit/sec.
Not sure if they're of much use to anyone, but I think they look pretty clean considering that I deliberately forced the conditions to be sub-optimal. You can see how noisy the still images are. Obviously reduction to 1080p helps a lot there.
Oh and don't complain about the piano playing. I think I was putting her off by continually pointing large lenses at her.
[edit] just wanted to add. These are all unprocessed straight out the camera (contrast, sharpness dialled down), imported into FC and then exported.
[edit 2!]
Also thought I'd throw up a low ISO shot from today as well. This was taken with the same patched AVCHD settings as before.
Exposure: 1/60sec
Focal Length: 140mm
Aperture: f/5.8
ISO: 100
Data rate according to Quicktime: 37.48 Mbit/sec
Still image
Video (approx. 46MB).

Thanks for posting the stills, video and settings, Paul. I'm going to pick up a Class 10 card or two here in a moment.
So the 84M buffer on your Class10 Card is going great? I tried it on this crap 16gb Transcend card and it looked like water paint. Went back to 40M and it fixed all of my issues.
Also, random, how do you like the 20/1.7? I can't seem to find any clips showing its strengths or weakness, particularly how it performs wide open with NDs with great composition.
Checking your video after it downloads.

Sorry? These are AVCHD clips.

Ah I see what you're saying. No - they've been passed through Final Cut (as I mentioned in the post). The export was at the highest settings. If you really want the MTS files I can put them up I guess...
