what i needed to copy & paste were exactly laid out in another Project. i just needed the chunks copied and put in between bits of another Project. they didn’t need to trimmed or re-edited. so (sigh)… i did everything i needed to do with the Project to be copied from: exported, uploaded, given a final approval. once i knew there were no further edits to complete on it, i took out all the transitions (all basic Fade to Color transitions) and exported a Quicktime file. now, i’m not at a proper computer, so i can’t detail what the settings are, but it’s the initial options that pop up; i just changed the option from “Open Quicktime” to “Do nothing.” because it’s exporting at the exact same quality as what’s in the Project, there’s either extremely little or no loss in quality.

once that finished, i simply imported that MASSIVE Quicktime file into FCPx. i laid markers into the Project to be copied into, then just did in & out points on the file to be copied from. dragged those bits into where they needed to go, and done.

of course, all of that is absolutely non-sensical, especially in light of my ability to copy & paste things in unrelated Projects to other Projects with any problem, whatsoever.

best of luck to you. judging by your last post, you’re not having much fun yet, and i don’t fault you, especially considering this your first time in anything FCP related. despite this kerfuffle/issue/nightmare, everything else i’ve edited in FCPx has worked like an absolute dream. i would suggest perhaps investing in Mr. Jordan’s training if you really want to know how to do most everything you need to do. it’s an incredible resource and tool.

again: good luck.
