It is often not possible to determine how long a title should appear when it is first created. I can modify the text a title after the fact, but I cannot modify its duration. How does one do this?
Welcome to the forum.
To alter the Duration of a Title (or Still Image), just click+drag on the Head, or the Tail. I like to also have the Info Panel open, when I do that, so that I can see exactly what the change is.
PS - before one creates a Title, or Import a Still Image, they can alter the Duration in Edit.Preferences>General.
