Proper Kona 3 Settings for RED proxy's

[Patrick Carpenter]

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.

This is a little hard to understand. So are you trying to playback 4k full proxies? or just 4k proxies in general? From our tests 4k proxies are less reliable then 2k proxies, and generally even on a good system doing anything higher then M is ruff. For 4k proxies I like to work with the S or even the P and that's on a 8core with 8+ gigs of mem. I guess what I really need to know is what kind of system are you on (ie how good is your mac)?

I've tried them all. The system that i was attempting to play them back from is a 8core mac @ 6 gigs of ram. Being they all yielded similar results in playback (F,Hand P) I began to suspect a kona setting might be wrong. Stuttered playback, pink frames, frozen image, ect. Sync feed to box is correct. Hope this help clarify. I'm trying to get on our other FCP station that has over 16gigs of ram but it's midway thru another project.

So far my best results in 4KHD are from the _M proxies (960x540) but place them into a 1920x1080 timeline and scale them 200%. Then use an AJA 1920x1080 setting, such as 1080p23.98 8-bit.

The key is to make the timeline compatible with AJA, not the source file or proxy size. If its still too jerky in unlimited RT you can go down to the _P's and scale 400%.
