vertical-video

Make vertical 9:16 (or square 1:1) short videos for YouTube Shorts, Instagram Reels and TikTok from footage the user already has, with automatic reframing of 16:9 clips. Local with Reelary on Mac or Windows. Trigger on "shorts", "reels", "tiktok", "vertical video", "9:16", "square video", "social clip from my footage", "repurpose my footage for social". Not for posting to social networks or AI avatar videos.

If the reelary_* tools are missing or nothing is indexed, use the reelary skill first.

Steps

1. Get the hook and 3-8 beats (short-form favors a strong first 2 seconds). Keep the total under 60 seconds.
2. Call reelary_rough_cut with the beats as script, aspect: "9:16" (or "1:1") and max_clip_seconds around 3. 16:9 clips are reframed automatically.
3. List each scene with its clip; for empty_scenes suggest rephrasing, and set chosen to 1 or 2 to swap a weak pick.
4. reelary_save_project, suggest reelary_open_in_app to add captions or music, then reelary_export_video and poll reelary_job_status until done.

Without MCP: npx -y reelary cut "<beats>" --aspect 9:16 --save "<name>" then npx -y reelary export <project_id>.
