Final Cut Pro X transitions when you don’t have enough media
In some situations you’ll get this message when you attempt create a transition between two clips in Final Cut Pro X:
There are new extra frames after the end of the outgoing clip and frames before the start of the incoming clip for the transition to work with. This applies to compound clips and other kinds of media as well as video clips.
There are many cases when you won’t want Final Cut to ripple trim the clips and reduce the duration of the storyline you’re editing.
An alternative is to use an Adjustment Layer to apply an effect to the end of the outgoing clip (or clips) and the start of the incoming clip, and to animate the effect’s parameters so the effect is strongest at the first frame of the incoming clip:
