wjs-overlaying-videolisted

Use when the user has one or more video clips and wants to add post-production on top — AI-generated cover as first frame, HTML/CSS captions synced to SRT, kinetic illustration overlays at hook moments, chapter chips, end-card CTA, or any other timed motion graphics. Most often used as the downstream of `/wjs-segmenting-video` — pick up where that skill stopped (raw cropped clip + per-clip SRT) and produce the upload-ready MP4. Backed by HyperFrames so everything compiles to ONE final encode — no cascade of re-encodes. Triggers — "加封面", "加字幕", "加动画", "加 CTA", "做后期", "post-production", "title card", "kinetic captions", "end card".

# wjs-overlaying-video Post-production for a video clip: cover, captions, illustrations, CTA, custom motion graphics — all composed in ONE HyperFrames project and rendered in a SINGLE final encode. No cascade of decodes/re-encodes (each cascade pass degrades quality and burns time). ## When to use - **Downstream of `/wjs-segmenting-video`** — the segmentation skill hands you cropped clips + per-clip SRTs; this skill turns them into upload-ready MP4s with cover/captions/illustrations/CTA. - User has a finished video and wants to dress it up with motion graphics: opening hook, key-quote callout, closing slogan, chapter cards, AI-generated cover as first frame. - User wants HTML/CSS-quality captions on a video (kinetic word-by-word highlighting, custom fonts, large outlined text, seekable per cue). - User wants illustration overlays at specific hook moments — diagrams, big text emphasis, flow charts. **Don't use** for: - Splitting one long video into clips → use `/wjs-segmenting-video`. - Creating the source SRT → use `/wjs-transcribing-audio` (then `/wjs-translating-subtitles` if you need a different language). - Full HyperFrames productions where the source isn't a fixed video → use `hyperframes` directly. - 微信视频号 / 抖音 upload (no public API for those) → this skill produces the MP4; upload is manual. ## What this skill IS — and IS NOT | Is | Is not | |---|---| | Everything that goes ON TOP of a video clip: cover, caption, chapter, illustration, CTA | Cutti
