Here is my first preliminary test comparing the hacked GH2 vs the GH1. The GH2 was using the following settings
720p SH mode
This is not a recommended setting, but has been working just fine for me producing 720p footage with average bitrates over 40mb a second with out causing any errors on PNY cards.
Just a slightly higher bitrate than Vitality’s recommended settings. Again, Vitality is stressing not to mess with the GOP right now, as I did with 720p, so do so at your own risk.
The GH1 was using lpowell’s 75mb high reliability patch
Both cameras used the same lens, same f-stop WB kelvin and shutter settings. The GH1 was used at 100iso and the GH2 at 160iso accounting for the difference in ISO ratings between the cameras.
Thanks to mpgsvcd in this thread: http://www.personal-view.com/talks/discussion/335/ptool-3.60d-gh2-avchd-encoder-settings/p1 We now have a greatly improved 720p mode for the GH2, and the first useful bitrate hack for the camera. Play the video below in “Original” quality on youtube to take a look at how the windmill motion is captured. For the most part, this will remove the macro blocking that was evident in this mode due to the low bitrate before the hack.
Vitality does it again! I’ll have more information as I start and try the patches myself. For now the most recent information is in this forum.
