I'm tasked to change a graphic title in a credit roll, and re-insert into a 23.98 SR master, plus one scene at the head of the tape.
The first insert goes in as planned... cue to the tail, set In/Out and insert Video Only. FCP aborts the insert every time. No amount of rebooting, preferences, nothing.
Eventually it dawned on me that FCP was choking because the video that I was trying to insert is text. When I rendered out the credits as Quicktime, reimbedded in the timeline and re-attempted the insert, it worked.
