You can set how quickly you want the titles in your project to fade in and fade out. Setting the title fade duration makes the title appear more slowly or quickly over the video; it doesn’t affect the total time the title remains onscreen.
All titles in your project fade in and fade out at the same rate.
To set the title fade:
Open a project, and then choose File > Project Properties.
The File menu appears in a light gray bar across the top of your computer screen.
Drag the Title Fade Duration slider to the left to make titles fade in and out more quickly, or to the right to make titles fade in and out more slowly.
You can’t set animated titles to fade in or out.
