“We’re talking about recapturing just the finished Sequence. Even if you highlight the clips in the Sequence, FCP will recapture all the raw media from those clips, not just what’s in the Sequence. Media 100 would only capture the exact media in the timeline. ”
That’s not true…
You can create a duplicate of your sequence, make offline clips and capture these clips which have only media used in the sequence plus handles you specify. And you can retain your original sequence linked to the original full media.
Its all explained on page 1452 of the user guide and I’ve had occasion to use this many times. Of course this procedure is only as accurate as the original capture was. People who name (or allow names to be) tape names like “001”, or do “Capture now” and don’t name clips before capture, resulting in scores of “Untitled, Unditled01” etc, would have some trouble making this work.
