Short-Form Video Script Structure: Hook, Setup, Value, CTA

If you are not on camera, the script is the video. There are no facial expressions to lean on and no charisma to paper over a weak line. The good news is that structure is learnable in an afternoon, unlike presence.

This is the structural reference: the four parts, how many words each one gets, three templates to copy, and the specific way each part fails. For the texture of the sentences themselves, see how to write scripts that sound like a person.

First, the word budget

Speaking pace is about 2.5 words per second, so length is arithmetic:

Video length	Total words	Hook	Setup	Value	CTA
15 seconds	35 to 40	8	5	20	5
30 seconds	70 to 80	10	12	48	8
45 seconds	110 to 120	12	18	75	10
60 seconds	145 to 155	12	22	105	12

Write to the count, not to the feeling. A 30-second video carrying 120 words is a 48-second video that people skip.

The proportions matter more than the exact numbers: the value section takes 60 to 70% of the words, and everything else is scaffolding around it.

Hook: the first three seconds

One line. It has to work with no setup at all, because there is none yet.

• “You are editing videos the slow way.”
• “I posted every day for 30 days without showing my face. Here is what happened.”
• “There is one setting that doubles your watch time.”

Four hook shapes that reliably work: a bold claim, a specific number, a question the viewer has already asked themselves, or the end of the story told before the beginning.

How it fails. It announces instead of starting. “Today I want to talk about video editing” is an announcement. Anything beginning with “Hey guys” has already lost. The other failure is a hook that needs context to make sense, which by definition it cannot have.

Setup: one or two lines

Just enough context for the value to land. Who this is for, or what the problem was.

• “I used to spend two hours per video trimming clips and syncing captions.”

How it fails. It becomes a preamble. Every sentence here is a sentence the viewer might leave during, so if the value would land without a line, delete the line.

Value: the middle, and the reason the video exists

Teach one thing. A method, a result, a story with a lesson.

• “Now I write the script first, paste it into a tool that generates the voice, the captions and the cuts, and I spend the time I saved on the next script.”

One idea per video. If you have three, you have three videos, and posting three is better for you than cramming three.

How it fails. Two ideas. It feels generous and it halves the completion rate, which is the metric that decides whether the video gets shown to anyone new.

CTA: the last line

Say exactly what to do. Follow, save, comment a word, open the link.

• “Save this for the next time you are staring at a blank timeline.”

How it fails. Asking for three things, or summarizing. The viewer was there thirty seconds ago and does not need a recap.

Together, those four parts come to about 75 words: a 30-second video.

Three templates you can copy

Replace the brackets, keep the rhythm.

The result template

“[Number] [thing] in [time] without [pain]. Here is what I did. First, [step one]. Then, [step two]. The part that mattered was [insight]. Do this and [result]. [CTA].”

The mistake template

“Stop [common action]. It looks productive and it is killing your [metric]. The reason: [mechanism in one line]. Do [alternative] instead. I switched [time ago] and [specific result]. [CTA].”

The story template

“[Moment where things went wrong]. I thought [assumption]. Then [turning point]. What I learned: [lesson in one sentence]. If you are [situation], [advice]. [CTA].”

When the structure changes

Under 15 seconds, drop the setup entirely. Hook, value, CTA. There is no room for context.

Over 90 seconds, the single value section becomes three beats with a small hook in front of each, because attention has to be re-earned roughly every 20 seconds.

Tutorials invert the proportions: the setup shrinks to nothing and the value section becomes numbered steps, where the numbering itself does the work of holding attention.

Using it

Write five hooks before you write anything else. Hooks are the hard part, and separating them keeps you from polishing paragraph two of a video that has no reason to exist. Then fill in the rest for the ones that survived.

When a script is finished, the production workflow takes it to a posted video. In MonkeyTalker that loop runs about three minutes per video once your character exists, and the free plan needs no card. Write one 75-word script with the structure above and put it through today.
