Tony,
If you missed this step, here’s what I do. And it’s not updated yet in my article except in some of the comments.
I let FCP capture a whole tape, and I’ll name the capture something like Tape 001.
When it’s done there are lots of clips in the browser, depending on how many times the camera was started. I then open each clip into the viewer, and decide if I want to keep it, and change the name to something appropriate. I also open my capture scratch folder, and any of the clips I don’t want, I just toss from there.
After all the clips have been renamed in the browser, I select them all and control click to rename, file to match clip. in an instant, you see all the QT clips in your capture folder change, and you’re done.
Does this help?
