Video script generator that writes YouTube, Shorts and Reels scripts from your content

How long should a video script be?

Work backwards from the runtime. Natural spoken delivery lands at roughly 150 words per minute, a little slower for teaching, a little faster for high-energy short-form. That single number gives you every script length you need: about 75 words for a 30 second Short, about 120 to 150 for a 60 second Reel, and roughly 1,200 words for an eight minute YouTube video.

The mistake is writing to a word count instead of to a runtime. A script that reads well on the page but runs 40 seconds over gets butchered in the edit, and what gets cut is almost always the specific detail that made the video worth watching. Write to the clock and the edit stays intact.

Short-form has one more constraint that long-form does not: there is no runway. You cannot spend eight seconds introducing yourself, because the swipe happens first. The hook has to carry information, not throat-clearing, and the payoff has to arrive before the viewer decides you are stalling.

Writing the hook, which is most of the job

A hook works when it opens a gap the viewer wants closed. The reliable shapes are a specific claim that sounds contestable, a number that is bigger or smaller than expected, a mistake the viewer is probably making, or the end of the story told first. What does not work is a greeting, a channel intro, or a preamble about what the video will cover.

Because Adapter.to writes from a source, the hook has something real to reach for. If your blog post contains a result, the hook can lead with that result. If your podcast contains a disagreement, the hook can lead with the disagreement. A blank-prompt script generator has to invent a hook, and invented hooks are exactly the ones that sound like every other video in the feed.

Once the script exists, the rest of the launch is downstream of the same source. You can pull the YouTube title options and the YouTube description with timestamps, the TikTok script for the vertical cut, and the posts that promote the video on LinkedIn and X, all from the one source you already pasted.

If the video is specifically a YouTube upload rather than a generic explainer, the YouTube script generator is the version tuned to that: script length worked back from your runtime, sections that become chapters, and a hook written for the first fifteen seconds where YouTube decides whether the video travels.
