Here's a wierd one!
Open project file, save as new project name. Import new photos and sound tracks, start new sequence. Add the elements to the sequence: premixed track, jumpback bg, still image, edit in appropriate b-roll with 8 point matte. Here's where it gets wierd.
Because the type treatment of the original show is a huge part of the new one, I opened one of the original sequences, pasted one of the lower thirds over the new sequence. Fine, just changed the name and title and location. Kept all the attributes. All good. Then selected a "call out" piece of title from the original sequence and pasted that in. IT DOESN'T SHOW UP IN THE TIMELINE, BUT I GET A RED RENDER BAR WHERE I PLACED IT. I can see it in the canvas. If I double click it, it opens in the viewer and from there I can cut it in again. There's nothing to select to delete the original instance.
I'm about to repair permissions, run fcp rescue and I hope it will then show up. Phantom clip!!
Strange. Anyone else ever see this one?
