Conflict While Changing Cross Dissolve Duration in FCP
If you are unable to change the duration of a Cross Dissolve while working in Final Cut Pro, chances are their is not enough pad on each clip to allow for it.
When I say pad, I'm talking about the fact that in order for FCP to perform a cross dissolve, their has to be enough media at the end of the out going clip and at the head of the incoming clip to allow for it.
Example: if your original captured media clip was 8 seconds long, when you set your in and outs for the clip, the in point should be marked somewhere around 3 seconds into the clip. It doesn't really matter where the in point begins Just don't place it at the very beginning of the captured media. The same goes for the end of the clip. Don't place your out point at the very end of the captured media, unless you know that you are definitely going to perform a straight cut into the next clip. The room that you are leaving at the beginning and end of clips is what FCP will use to perform the Cross-Dissolve.
