Iv'e been trying to get proper playback of the RED proxy files in FCP. I've followed the Kona's white paper to no sucsess. Where I have been Scratching my head is the Footage was shot 4K Hd: 3840x2160. So dragging the proxies across yields 1920x1080, 960x540, and 480x270. I cannot find a Kona playback setting that plays these back without causing much havoc in the image. Most of the white paper and playback settings refer to 2K proxies, 2048 and their derivatives. If there is any direction that this list could offer it would be greatly appreciated. Proper Codecs installed.
