# Subtitle & Caption Skill

Subtitles fail when they're too long to read before they vanish, badly segmented, or a literal
translation that overruns the timing. Good subtitling obeys real constraints: **reading speed** (≈17
chars/sec / ~160–180 wpm), **line length** (~42 chars), **max 2 lines**, and sentence-aware segmentation.
This skill writes or translates captions to those rules — readable, well-timed, and condensed to fit.

## Required Inputs

Ask for these only if they aren't already provided:

- **The content** — a transcript, script, or existing subtitles (with timecodes if you have them).
- **Task** — caption (same language), translate-subtitle (to another language), or SDH (deaf/HOH captions with sound cues).
- **Format** — SRT, WebVTT, or plain; and any platform limits (YouTube, broadcast, Netflix-style specs).
