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, speed ramp), transitions (whip pan, zoom, glitch, light leak,
masks, FFmpeg xfade, Remotion and shader transitions), words on screen (headlines, callouts, lower
thirds, reviews, end cards and CTAs), showing a product (UI walkthroughs, cursor clicks, device
mockups, code and terminal screens, agent flows) and visuals (counters and charts, logo walls,
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 animated number or chart, a logo wall or a background
while editing a video. Not for choosing an editing service (use varg-video-editing) or generating
new footage (varg-ai).

The takes are text. Building them needs ffmpeg for the FFmpeg recipes, Node for HyperFrames
(npx hyperframes) and Remotion, and nothing for the CapCut steps a person follows by hand.

# 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
- One transition family per video. Mixing whips, glitches and page curls in one edit looks like a template sampler.
- Most joins should be plain cuts. Use a transition where it means something: a change of place, time or idea.
- Before you join clips in FFmpeg, normalise frame rate, timebase, resolution, SAR and pixel format (`fps=30,scale=1920:1080,setsar=1,settb=AVTB,format=yuv420p`). Mismatched inputs are the most common reason `xfade` and `concat` fail.
- Keep on-screen text inside the safe zone: 10% from the edges on 16:9, and clear of the caption and UI bands on 9:16.
- Text stays on screen at least as long as it takes to read twice; numbers land on a round, final value and hold.
