Thanks for your helpful comment, Jim. What I meant is obvious if you've ever seen it on a SpeedGrade timeline: clips which are brown in color, have no information, and represent parts of the imported timeline which were, for whatever reason, not transferred/imported into SG. So you have an incomplete timeline, which means, if you were to work all day and all night on it and, say, ignore those "brown clips", you'd then be saving and exporting back to Premiere a color-graded but incomplete set of instructions, and I don't know what that would do to the project, nor am I going to try. Does that make it kind of clearer?
By the way, FYI, there's a new e-book on SpeedGrade, which I hope PeachPit Press will print and publish as a normal hand-holdable book:
Adobe SpeedGrade: Getting Started, 1/e
You can get it for the Kindle or the Kindle app.
