SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve? Turning long lecture, live-session, or cohort recordings into polished captioned videos requires manual transcription, subtitle timing, slide detection, and multi-part video assembly. This Skill automates that entire pipeline from raw Zoom or screen recordings to a distributable 1080p MP4. ## Core Features & Use Cases - Automated Transcription & Correction: Converts Zoom WEBVTT transcripts or chunked Whisper output into word-timestamped segments, with LLM-based proper-noun correction. - Karaoke-Style Subtitles & Assembly: Generates ASS subtitle files with word-level highlighting, slide title cards, zoom effects, illustration overlays, face PIP, and endcards via a config-driven ffmpeg render script. - Distribution Pipeline: Uploads to YouTube as unlisted and posts Discord forum announcements with automatic 7-day link expiry for cohort sessions. - Use Case: You have a 2-hour Zoom cohort session recording. Run the lightweight path to produce a captioned video with endcard in a few hours, upload it unlisted to YouTube, and post a Discord notice that expires automatically. ## Quick Start Ask the agent to turn the lecture recording in this folder into a captioned video and prepare it for Discord sharing.

Frequently Asked Questions about lecture-recording-captions

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add subtitles to a lecture recording automatically?▼

Convert the audio to timestamped segments using Whisper in 10-minute chunks or reuse a Zoom WEBVTT transcript, then run the provided scripts to generate ASS subtitle files and an ffmpeg render script that burns karaoke-style captions into the video.

Can I use Zoom cloud transcripts instead of Whisper for subtitles?▼

Yes. Zoom cloud recordings include a WEBVTT transcript whose Korean quality is comparable to Whisper. Convert it with vtt_to_segs.py, fix proper nouns, then run add_words.py to create the word-level timestamps the renderer requires.

Why does make_video.py fail with KeyError: 'words'?▼

The renderer requires word-level timestamps in each segment for karaoke highlighting. Sentence-level sources like Zoom transcripts lack them, so you must run add_words.py first to distribute timing across words proportionally by character count.

What ffmpeg build is needed for ASS subtitle rendering on macOS?▼

The default Homebrew ffmpeg lacks libass and freetype, so ass and drawtext filters are unavailable. Install ffmpeg-full and use /opt/homebrew/opt/ffmpeg-full/bin/ffmpeg for subtitle burning and text rendering.

When should I skip slide title cards and zoom effects?▼

Skip them when the source screen constantly changes between slides, browser, and webcam, as with full Zoom window recordings. Set runs to a single full-length entry and leave titles, zoom, and illustrations empty so only subtitles and the endcard are applied.
