Look at the video below shot by @bwhitz to test the low gop avchd hack . If you have not seen it before it sure is very very good and the best advert for the GH23, GhVK etc... I find it to be very jello/wobble free, more so from how it was shot. If you read the comment section, you will see that he could not get any stabilizer and had to shoot handheld and many shot are... in a moving train. I can't think of a lot of situation that can be worst than that. Now if you look at the shoots you can see that it has a lot of motion and in the train ones vibration. But strangely it is quite jello/wobble proof.




I know that as some said it before that the speed of the sensor does not change with the hack. In this case (low gop), I am asking myself if on longer gop the jello is more amplified because the codec is calculating much more from a single I frame every 12 frame. Like a cascading effect, where the next frame has to calculate from the last one that was compromised by the jello, and adds it next little motion which will affect the next one which will calculate from it, which result in a jello fest. I might be completely wrong in this but I am a bit intrigued by the above video, where with my experience you should see much more wobble. I did not see any post about it, if it has been discussed thoroughly, I don't mind if it is put back in the thread or deleted.
