This tab allows you to create a transition between the clip you have selected and the next clip on the sequence. Transitions will allow your clip to gradually transition to the next one.
Applying a Transition
There are two ways to apply a transition to a clip.
Adjusting the Transition's Duration
In the Transition tab, you can set the duration of your transition in seconds. You can also change a transition's duration by resizing the orange transition bar over the clip on the Video Track. Just drag and slide the bar to adjust the duration.
How to begin a movie with a fade-in
If you want your movie to start with fade-in effect, you need to insert a blank clip (using the "Insert Blank" button on the toolbar) before the first clip on the Video Track. With the blank clip selected, apply the "Fade" transition.
