THANK YOU !!!
yes...12800 ISO in all modes.
Ive proved you can drop a GH2 rig from 5 feet and it still works. Must have been the patch. ha
Thanks again for your help,

Although Flow Motion v2 works reliably with the extended ISO patch, recording at a high ISO will inevitably increase the GH2's sensor noise and decrease its dynamic range. ISO 12800 is noticeably noiser than ISO 3200-6400 and the increased noise level will consume a significant portion of FM2's bitrate. Personally, I prefer to minimize noise and maximize DR by setting ISO no higher than 1600.
800 ISO is my maximum speed when shooting with the GH2. Every time I've shot higher than this I ended up junking the footage because it just wasn't good enough. ( noise, banding, poor color, etc... )
If I need to go higher than this I would look at renting a Canon 5D MK3 ( $175 per day in Toronto ) or the Canon C300 ( $250 per day in Toronto, which seems like a steal ), or the Sony FS-100. ( $175 per day in Toronto )
My solution for ISO's higher than 1600 was to buy a Nikon D5100 ($550 @ Amazon), whose sensor has a 1.5-stop DR advantage over the GH2:

Naturally, that works best for those of us who bought Nikon-mount lenses to share between the cameras.

No, you'll need specific GH1 hacks for your GH1. lpowell has a 100Mbps patch linked above your post though. Give it a try.

My computers are struggling with playback after upgrading to the new Flow Motion patch. I used to be able to play them fine in VLC, but now the video stops and freezes up after a few seconds on almost all shots. Any suggestions on how to easily watch the clips so I can log them?
No problem here running Flow Motion ver 2.02 videos using either Windows Media Player or VLC Media Player : Windows 7 64-bit, old Intel i7 920 CPU, old ATI 4850 graphics card, 12 GB RAM, 120 SSD boot-drive.
This is the second time that this has happened to me, and I don't know if it's because of the Flow Motion hack. But when I press record to stop, my camera just freezes up and the only way (that I've found) to get it un-frozen is to remove the battery. And then of course that shot isn't saved. Has anyone ever experienced something like this?
That isn't old! I run an Win7 64bit, Athlon64 4200+, 2gb ram, Nvidia GTS250, 2gb ram, 1TB hdd. That's old!
My pc is about 4 years old, which I consider to be pretty out of date, but still usable.
What memory card are you using? The FlowMotion ver 2.02 patch needs a fairly speedy SD card when filming in 24H mode. ( 24L mode is less demanding on the memory card )

Erik, I'd look at the drives your using. You aren't playing the video straight off the SD card, right? Are your drives internal or external (usb)? Have you checked to see if they're fragmented to hell? That can cause your problem. I've never run into what you describe except when I'm playing files on an external slow USB drive while performing other file operations on the same drive.
I was using a Sandisk Extreme HD Video 16GB 30MB/s the first time and a Sandisk Extreme 32GB 45MB/s the second time. (This was on 2 different shoots / days). I was using the HBR mode.

Love love love the patch.. Only one 'bug'... When shooting in 24L the remaining time is completely incorrect. 24H doesn't seem to have this problem. Basically the counter will say example: 3 hours... but as it counts it will simply skip forward a second here and there. End up recording 2 hours and 20 minutes. Not a big deal if you have tons of cards, but very frustrating on a long shoot. I had an all day shoot with two 64gb cards and 4 16gb cards. Seeing as I can shoot around 3.5 hours on 24L on a 64gb card, I thought I was covered... Nope.. Had to kill off one of my other cameras to rob the cards to finish the shoot.
Still LOVE the patch, the counter just isn't accurate on 24L. Wonder if it would be possible to fix that glitch...?
My only other gripe is that in HBR mode I could only record 1.5 hours on a 64gb card... DANG. That wont do. My clients would laugh if I handed them 160+GB worth of files for a 4 hour shoot. If you can bring that down to a reasonable bitrate as an alternate patch, THAT would save my butt. Otherwise I'm back to Sanity 5 for HBR 25p shoots. I have one tomorrow so I had to get on here to find a 25p patch that wont eat through a 64gb card that quickly.
Seriously amazing work. Love the patch... Using it for everything except the shoot tomorrow!

In the course of developing Flow Motion v2, I encountered a wide variety of failure syndromes (and had to figure out how to fix them). This, however, is the first time I've heard of the GH2 freezing up when you try to stop a video recording. If you can recall the camera settings you were using at the time it froze, I'd be very interested to try to reproduce this behavior.
The inaccurate time counter in 24L mode is a side-effect of a technique I used to enable the GH2 to reliably span across 4GB files at bitrates as high as 60Mbps. Unfortunately, the time counter's calibration doesn't understand how to predict FM2's high bitrate usage.
The problem with HBR is that unlike the other video modes, Panasonic didn't provide us with a low bitrate option for it. As a result, Flow Motion v2 can only record HBR video with a peak bitrate of 100Mbps. I've been testing a lower bitrate version of Flow Motion recently, and have been debating how low a bitrate it should use. Have you found that 24L mode produces acceptable video durations on your SD cards?
I'm not sure what you mean by camera settings, I think on the first shoot I shot on Standard -1,-2,-1,-2 and second shoot I used Nostalgic at -1,-1,0,-2
Both of the shots were with a Panasonic 14-140mm lens, and froze during an outdoor shoot with HBR mode. The second shoot I was also using a Juicedlink CX231 + Rode NTG2 attached directly to the camera.
It's just weird that it only froze up that 1 time on both of those days.
...You need to keep in mind that the FlowMotion patch is a variable bit-rate patch, that will change it's recording bitrate depending on the complexity of the images it has to record. So I would always expect the time remaining to move around a bit depending on what I'm doing with the camera.
