The screenplay step is only as good as the story it reads. A few habits make the difference between a scene list you accept and one you rewrite.
Write in scenes already
Paragraph breaks become scene candidates. If your story jumps location or time, start a new paragraph. If two events share a place and a moment, keep them together.
Name people once, clearly
Introduce each character with a name and one visual fact. "Leyla, a courier in a yellow jacket" gives the character bible something to hold on to; "she" does not.
Say what the camera sees
Interior thoughts do not shoot. "He was afraid" becomes "he checks the door twice". The screenplay step keeps concrete actions and drops abstractions.
Keep dialogue short
Lines under twelve words survive lip sync well and read naturally in subtitles. Long speeches become monologues over B-roll, which is fine, but decide that on purpose.
End with an image
Close the story on something visible. The last scene sets the mood for the assembly and the music choice.
