How long should a YouTube Short be?
Shorts can run up to 3 minutes, but length and performance are different questions. Most Shorts that do well sit between 20 and 45 seconds.
Scripting and prompting
Writing the thing before you generate it — length, hooks, structure and captions.
Leaxor writes a script for every video, but knowing what makes a Short hold attention is still what decides whether it gets watched. The questions below cover how long a Short should run, how to structure the script, what a strong hook looks like, how captions get onto the video, and what a negative prompt actually changes.
They're answered for YouTube Shorts. Most of it carries over to TikTok and Reels.
How do I write a script for a YouTube Short?
Three parts: a hook in the first three seconds, the payload, and a resolution. Everything else is padding.
