This is the best thing I loaded to my GH2. Stable, reliable and excelent image quality in all modes, works for cards with 24/30/36/45MBps constant write speed or above depending on the version loaded. Best option is to use 45MBps cards and above, which I used for the tests.

setg is the recomended version, safe and great quality. seth and seti are for lower speed cards, but does not have same quality of setg. setj has more aggressive settings for even better quality.

four versions: (use setg if you have proper card, it is safe and avoids all mosquito noise and texture mud in the high bitrate modes)

setg: for cards with constant write speed 36MBps and above, I frames compression = 3

seth: for cards with constant write speed 24MBps and above, I frames compression = 4

seti: for cards with constant write speed 30MBps and above, I frames compression = 3.5

setj: for cards with constant write speed 45MBps and above, I frames compression = 2.5

The base is FlowMotion 2.02 from LPowell because he did a great careful job to tweak the quantization, matrices and tables and get perfect image quality in all modes with quiet camera or camera movements.

The modifications are in datarate and gop to make it completely stable and reliable without stop recording in all modes. For best image quality use the 24H, SH, FSH and HBR. The 24L, H, FH does not have the same quality and are for save memory space and for you to try in lower speed cards if needed.

The bitrate is very well distributed among the I, B and P frames giving a fluid random texture and noise in all modes and isos, The gops and datarate are well balanced to each other with the benefits from the quantization, matrices and tables from FM202.

In the setg 24H, SH, FSH and HBR, the texture is beautiful, noise is homogene, no macroblocking, no mosquito noise, no texture mud. Great use of the 8 bit codec in dark areas, excelent high iso performance which cleans ok with neatvideo and with a small amount of film grain you cannot tell it was shoot in high iso. Optimal results for blu-ray output and big screen projection.

720p 60p upscaled to 1080p works great for slow motion, just use your skill to denoise, sharp and upscale it. Apply film grain to your taste. If you like the feel of the original noise, just keep it, or just remove a little bit of chroma noise keeping the luma noise, and no need film grain.

No stop recording in all tests with setg. tested with green grass under sun and shadow and also tested in all modes with the four Stray's colour death charts. Tests done with 6400 iso which is very difficult to the hack to handle and it worked ok. Tests also done in the end of card space (3 minutes left) and no stop recording also. Sandisk 32GB SDHC 45MBps was used.

The audio has Pasadena settings, from FM202.

Spanning was not tested with this patch. Also it needs transcoding with 5DtoRGB free software before editing to avoid the diagonal pattern (rain). It is clean after converted to Apple ProRes. I Converted to the LT version with great results and smaller fle sizes.

If somebody wants to test spanning I recomend to use the lower bitrate modes and tweak the TOP and BOTTOM datarate limits in the advanced settings for testers in PTool.

Enjoy!
