The Reliable In-Camera Playback Patch will work on all GH1 and GF1 cameras. However, the GF1 is inherently limited to scanning its sensor at a rate no faster than 30fps. As a result, GF1 SH mode 720p50 and 720p60 videos are actually recorded at 25p and 30p, respectively. These video files contain duplicated frames in order to make them play back at 50p or 60p, as intended.

The Fast Action 3-Frame GOP Patch will work on all GH1 and GF1 cameras, but is particularly well-optimized for the GF1. Its SH mode records in native 720p25 and 720p30 formats, without inserting redundant duplicate frames. This patch's 3-frame GOP is also highly useful in recording rapid motion without smeared details. While this patch is currently compatible with PTool 3.55d, I'm working on a GF1-specific Version 2 release that will take advantage of PTool's new features.

Thank you a lot :) Now, if I'm right, you used to recommend the "LPowell: Fast Action 720p30/25" patch as the best one for GF1, even better than the "reliable" one. Are you planning to make V2 of that patch as well, or is this "Reliable In-Camera Playback Patch - Version 2" the best solution for GF1 nowadays? Thanks again :)
