Free app converts 4K Panasonic GH4 video to pristine 10-bit HD


The incoming Panasonic GH4 has broken new ground with 4K, high-bit-rate video for a mere $1,700, but if you want more than 8-bits? That'll be another $2,000 for the AV interface unit. Fortunately, hacker Thomas Worth has just released a simple Mac command-line program that'll let you do a neat trick with GH4 files: convert the 4K, 16-million color video to 10-bit HD with a billion hues. It works using pixel summing, in which the extra 4K pixels are used to fill in missing color information, resulting in true, 10-bit DPX files in HD. As shown after the break, the result is a sharper image, smoother color gradients, easier grading and less loss in detail during image processing. The only cost is much larger 17.7MB images, but then you can get a lot of hard drives for two grand.
