A Script That Splits Into Scenes Cleanly
Write the script so its sentence boundaries are the scene boundaries, and each scene contains the noun its visual has to match.
What it is for
Shapes a script so the tool's automatic scene split lands where you meant it to, and so each scene contains the word its visual will be matched against. Use it before generating a narrated video from text. It prevents forty-word scenes, stranded pronouns with random images, and a video that overruns its target length.
The skill
A script-to-video tool cuts your script at sentence boundaries and gives each piece its own visual. Your punctuation is the edit. Write it that way. - One visual idea per sentence. If a sentence mentions a warehouse and a phone, only one of them can appear, and you do not get to choose which. - Put the concrete noun in the sentence that needs the picture. A scene's visual is matched to the words inside that scene: "efficiency" returns nothing you want, "forklift" returns a forklift. - Split long sentences even where the grammar holds. Forty words become one scene sitting on one clip for fifteen seconds. - Never strand a pronoun in its own sentence. "It cuts the wait in half" has no subject to match, so it gets an arbitrary image. - Spell numbers, units and abbreviations the way they are spoken. Written "2026", "API" and "$4.5M" are a coin flip in a synthetic read. Length, before you generate anything: - Budget about 140 words per finished minute, then cut ten percent. Narration lands slower than reading, and every scene needs a breath at its edge. - The first sentence is the claim. Not a greeting, not the company name, not "in this video we will". - The last sentence is one instruction. A list of three is a list of none. After it generates: - Read the scene list before watching the video. A bad split is obvious in the list in ten seconds and takes ten minutes to find by scrubbing. - Merge any scene under about two seconds into its neighbour. A visual that arrives and leaves before it registers is worse than one fewer scene.
How to install it
1. Open the tool and start a new conversation, project or template. 2. Paste the text below wherever the tool keeps standing instructions — usually called system prompt, instructions, or persona. 3. Save it so it applies to every run rather than a single message.
