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).
• Constraints — reading-speed/line-length target if non-standard.
