Douyin Script Duration Calculator

Problem

Douyin talking-head videos often feel too rushed or too loose when pacing does not match a target length. Creators usually estimate speaking time by ear or re-record until the script fits 15s, 30s, 45s, 60s, or 90s. This skill turns that guesswork into a structured check before filming.

How it works

Given a script, it first counts characters in several views: total characters including punctuation, characters excluding punctuation, pure Chinese characters, and effective spoken words. It then estimates duration using common Douyin speech paces: about 2.8 chars/s for standard speech, 3.5 chars/s for a fast hook style, 2.2 chars/s for steady explanation, and 4.0 chars/s for urgent sales-style pacing.
It also matches the result to short-video formats, suggests a primary and fallback version, and can generate a 30-second condensed version or a 45-second standard version. The output includes a segmented shot-by-shot timeline, pacing, pause, subtitle, and camera-switch suggestions, plus a rhythm check for opening hook, information density, and closing call-to-action.

Boundaries

This is a local, text-based duration and pacing aid for Chinese talking-head scripts. The speed model is heuristic; real timing still depends on pauses, emphasis, tone, and visual cuts. Condensed versions may lose nuance, so review the final wording before recording.
