This is termed CUT TO, and is unnecessary to write in the script unless there is some risk of confusion. This means the ending scene, or shot, fades out while the next fades in. FADE OUT at the end. Both terms are unnecessary . If you need to fade to black, write FADE OUT at the right margin.

Specifying shots and other technical things interferes with reading the story. Avoid using shots if at all possible. The writer's job is to tell the story in words. The director's job is to tell it cinematically. He will decide what shots are necessary.
