Since Shorts are fast-paced, your "write-up" (script and description) should be concise:

YouTube automatically categorizes videos as "Shorts" if they meet these criteria: MP4 or MOV. Aspect Ratio: Vertical 9:16 (portrait) is recommended. Resolution: 1080 x 1920 pixels is standard.

For videos under 60 seconds, aim for a script of 30–45 seconds to leave room for visual pacing and prevent going over the limit.
