[illya laney] "So dynamic and unlimited won't help timeline playback when a color correction or LUT filter is applied?"
They can, but the poster is working with PR4444 media on a 2008 powerbook, unless they are working on an Esata array- the content will never playback in realtime- the disc speed is not fast enough to handle that data stream-
it has nothing to do with RT if the disks are not fast enough.
