varg-video-edit-library

A library of named edits an agent adds to footage, each with what it looks like, when to use it, the common mistake and how to build it in FFmpeg, HyperFrames, Remotion and CapCut. Cuts and pacing (J-cut, L-cut, match cut, jump cut, speed ramp, smash cut), transitions (whip pan, zoom, glitch, light leak, masks, every FFmpeg xfade, Remotion TransitionSeries, HyperFrames and GL shader transitions), words on screen (headlines, callouts, lower thirds, quotes and reviews, end cards and CTAs), showing a product (UI walkthroughs, cursor moves and clicks, device mockups, code and terminal screens, AI agent flows) and visuals (counters and charts, customer logos, grids and carousels, backdrops). Use when someone asks for a transition, a cut, a title, a lower third, a testimonial, an end card, a CTA, a screen-recording zoom, a cursor, a phone or laptop mockup, a code or terminal animation, an agent workflow animation, an animated number or chart, a logo wall, a carousel or a background while editing a video. Not for choosing an editing service (use varg-video-editing) or generating new footage (varg-ai).

# Video edit library

Named edits for footage you already have. Every take in `references/` gives the look, when to reach for it, the mistake people make with it, timings, and a recipe per engine: FFmpeg for flat files, HyperFrames (HTML + GSAP) or Remotion (React) when the edit is a composition, and the CapCut path when a person will finish the edit in the app. The cards with previews live at https://skills.varg.ai/browse/edit-video/.

Most takes are built on open components from other people's libraries: HyperFrames by HeyGen, remocn, GL Transitions, Magic UI, Aceternity UI, Fancy, Codrops and others. Each take names its component, author and license; keep that credit when you use it.

## How to use it

1. **Name the take before you build it.** Read the person's ask ("make the logo pop at the end", "zoom into the button when I click") and find the take in the index below. Open only that reference file.
2. **Pick the engine the project already uses.** A plain MP4 and a shell: FFmpeg. A HyperFrames or Remotion project: that framework's recipe, and the listed registry component when one exists (`npx hyperframes add <name>`, `npx shadcn@latest add @remocn/<name>`). Do not switch frameworks for one effect.
3. **Keep the timing from the card.** Durations and easing are the part people get wrong. A transition longer than 12 frames at 30 fps starts to read as a scene of its own; text needs at least the time to read it aloud.
4. **Check the cut.** Grab a still at each edit point (`ffmpeg -ss <t> -i out.mp4 -frames:v 1 edit-<t>.jpg`) and look at it before you hand the video back.

## Rules that hold for every take
