Thanks. That's what I get for going into this half-informed with a full head of steam. I went back into Cinematize and imported a test section as 4:2:2 uncompressed and it looked a hell of a lot better. I was following someone else's 'template' so to speak when I imported things as DV footage. If the uncompressed video isn't prohibitive in terms of space, I'll probably have to go back, locate the in and out points of my original imports, and replace the source files.
