A few days ago Thomas Worth of Rarevision (5DToRGB and RAWMagic) asked me for some original files from the GH4 so he could develop an experimental app he had in mind. The result is an embryonic new command-line app for the Mac, which takes 8bit 4:2:0 4K H.264 files from the GH4 and resamples them to 10bit 4:4:4 in 2K DPX format.
These images (download the original 4K file at Vimeo to get even a clue of the full performance of the camera) are rather lovely. I’m also very impressed with the 2K slow-mo at 96fps. It is an improvement on the KineRaw MINI from last year which only shot 96fps at 720p, though there is still some moire and aliasing at the higher frame rate.
