@peternap, I made sure not to include any footage with the exposure trail / judder symptoms; I was only mentioning it as an anomaly that I noticed in some of the footage later in the day, after the GH2 had been cooking in my camera bag under the sun.
@LPowell, never noticed any frame rate issues / judder, or anything out of the ordinary in your footage after it was baking in the sun for a while?
Read review of sigma lense on bhphoto that it had what he called ghosting trails. Might be what you describe as exposure trails? Here is copy and paste of reviev:
This lens is overall great. fast, sharp focus, very sharp image overall. The only problem i noticed right away was a blue ghosting on high contrast objects, such as black and white text, or even outdoors where a light wall meets a darker colored background. This only occurs within the f/1.4-2.8 range. Sadly, i bought this lens specifically to use in that range. The ghost color is not particularly noticeable at 1:1 or less, but if you need to crop to a certain area, you'll be out of luck.
Another flow motion test here. I noticed for the first time after my GH2 had been sitting in intense heat for a few hours that there were are times where the framerate got a little wonky and there were exposure trails which normally would not be there. Don't see how the 2 are connected at all though. I did this video to test low light and a higher 1600 iso to see how well it holds up. You have to download if you want to see what the shadows actually look like.
Hmm, no matter what setting, AF100 just seems inherently soft. Great thing about the GH2, is that with just the right pick of the lens and an ND fader, sharpness at -2; it achieves that perfect level of sharpness, very much like film. Af100 is a vastly superior tool when all options are considered... but for pure iq, it seems so far behind at this point it just makes you shake your head.
I have af100 camera and gh2 and i consider af100 to be the better camera on overall performance. Gh2 has better resolution but not so much as in the video. Af100 has a lot more settings than gh2 to tune to get the picture you like. If you film a closeup of a woman you usually make the picture softer, on af100 you can adjust the detail level to make that shoot. In gh2 you have to do the softening in post. LPowells video was filmed with -3 on detail and i think that is a little to soft. I seldom go under 0 detail because then picture starts getting soft and i dont like it since i use gh2 as b cam
I recently revised my settings and got much better results from the AF100:
GH2 Daylight Settings
Film Mode Smooth
Contrast -2
Sharpness -2
Saturation -1
Noise Reduce -2
WB Daylight
A-4
M-2
AF100 Daylight Scene File
Gamma CINE-LIKE D
Matrix NORM2
Detail Level -2
V Detail Level -2
Detail Coring -7
Chroma Level -1
Chroma Phase 0
Master Ped -9
DRS OFF
Skin tone DTL OFF
Here's a more clinical comparison the AF100 (left side) vs Flow Motion v2 (right side):
Lens: Leicasonic 14-50mm f2.8-3.5
ISO 200; f6.3; 1/60 second
AF100 Scene File was matched to GH2, using CINE-V with NORM2, WB 5.6K
GH2 patched with Flow Motion v2, in Smooth Film Mode, WB Sunlight A-4 M-4
AF100 footage was shot in 1080p30 PH mode.
GH2 footage was shot in 80% Slow Motion in 24H mode, and conformed to 30p.
Footage was cropped and composited in After Effects CS5.5, rendered at 50Mbps.
GH2 Film Mode settings:
Smooth
Sunlight WB
A-4
M-4
AF100 Scene File settings:
Detail Level: -3
V Detail Level: 0
Detail Coring: -4
Chroma Level: -2
Chroma Phase: 0
Master Ped: -2
DRS: OFF
Gamma: CINE-V
Matrix: NORM2
Skin Tone DTL: OFF
Sorry for the delay in production, but I finally updated the first post at the top of this page with a video comparison between the AF100 and Flow Motion v2. What was challenging was matching the AF100's dynamic range and color balance to the GH2. While I'm not completely satisfied with my settings, I think it's close enough to judge the motion picture quality of the two cameras. I'm actually quite pleased with the GH2 color balance:
Smooth Film Mode: -2, -2, -1, -2
Sunlight White Balance: A-4, M-4
On the AF100, I used CINE-V gamma and the NORM2 matrix. While I like the look, I think it has a bit more contrast than the GH2 in Smooth Film Mode. As expected, AF100 details aren't as sharp as the GH2 using Flow Motion v2. I'd like to see how much I can sharpen the AF100 before noticeable aliasing sets in...
Here it is again, AF100 on the left, Flow Motion v2 on the right:
@wilcovdakker Yes, you can combine anamorphic MJPEG settings with the AVCHD settings in Flow Motion v2. Here's a link to a downloadable PTool patch file for the anamorphic version of my GH2 100Mbps MJPEG Low Light Patch:

@L1N3ARX "Having fun grading some flow motion V2.02 footage. Trying to go for an organic film-like look here."
Both videos look great! It's almost a better look than film IMO. Organic, yet hyper-real. What lenses are you using here?
Edit: Oh ok, Simga 30mm 1.4... just looked at the vimeo description. That's my "go-to" lens on the GH2 as well. Love it.
I read somewhere that flowmotion would allow me to have immediate in-camera playback and allow me to cut down or turn off the AGC via the Pasadena settings. Is this true?
Basically, I am looking for a stable patch that provides a high bit rate and the ability to directly playback in cam without the need to switch it off first. I am also wanting to implement the Pasadena sound settings.
I am more interested in stability and direct playback than push the camera to its limits. As far as the sound hack goes I am just trying to limit or eliminate the Automatic Gain Control (AGC).
@Cavemandude I'd be interested to examine a sample of your original GH2 footage if you can make it available for download?
