Optimize your video creation workflow with Remotion.

Add, replace, and optimize the looping demo videos in the onboarding "welcome" bento grid (packages/ui/src/features/onboarding). Covers the ffmpeg compression workflow (the scripts/optimize-onboarding-videos.mjs wrapper), the faststart + right-size best practices that keep playback smooth, the first-frame poster convention, and how to wire a new clip into WelcomeScreen. Use when onboarding demo clips feel laggy, when a clip is being added/swapped/re-recorded, or when posters and videos drift out of sync.

Produces Hunk videos by driving the real TUI headlessly in a PTY, compositing captioned 1080p frames in Chromium, and encoding with ffmpeg. Use for feature demos, workflow explainers, announcements, launch videos, and full-release roundups.

This skill should be used when comparing two videos to analyze compression results or quality differences. Generates interactive HTML reports with quality metrics (PSNR, SSIM) and frame-by-frame visual comparisons. Triggers when users mention "compare videos", "video quality", "compression analysis", "before/after compression", or request quality assessment of compressed videos.

AI audio editing pipeline: Whisper word-level transcription → Claude segment classification (KEEP/CUT_FILLER/CUT_FALSE_START/CUT_STUTTER/CUT_DEAD_AIR) → ffmpeg with 40ms qsin crossfades and room-tone fill → optional Cleanvoice cloud polish; plus GateScan/GateRepair for noise-gate ticking artifacts. Modes: --preview, --aggressive, --polish. Workflow: Clean. USE WHEN clean audio, edit audio, remove filler words, clean podcast, remove ums, cut dead air, polish audio, trim recording, cut stutters, ticking audio, clicking audio, audio clicks, gate artifacts, popping audio. NOT FOR video composition (use Remotion).
