GH2 Recording Problem - Can anyone help me with this

Jeff. OIS should ALWAYS be OFF when mounted on a tripod and probably also on a shoulder mount or stabilizer. If left on it interprets ANY movement as something to be compensated for.

What caused your problem could be anything that caused a slight movement you likely couldn't even feel, a gust of wind, a "flexing" of the floor a bit of a distance away from you. You've already found out you can record without getting that jump by keeping the OIS OFF so you essentially solved your own problem.

I encountered the same problem while shooting an indie feature this past weekend with my GH2. Random video stutter, just like in Jeff's vids. My first suspicion was that it might be related to monitoring on an LCD via HDMI, and I know Panasonic cripples this output with random frame drops. But then I looked back at some video I shot without the HDMI monitor and saw the same stuttering. The OIS on the lens was my next suspicion, although it seemed counter-intuitive that something that's supposed to stabilize an image can actually destabilize it!

I checked some footage from the same shoot where I used a Canon lens instead of the Panny 14-140. No stutter. There ya go.

Hoping others can verify this, and maybe we can get Panasonic to solve it with a firmware upgrade? Until then, OIS goes OFF.

I have had the same effect where you get an occasional "blip" where the picture jumps for about a couple of seconds. It seems to only occur when the MEGA OIS is being used. I might have expected this effect if the camera was on a tripod or some other support- but in my case the camera really is being hand held for which the OIS is intended! I noticed that on the various firmware updates most relate to the OIS in video mode with the last one saying it was improving the stability of the OIS in video. So perhaps it is a bit of a weakness in that area?
