# Invisible Cut — effect skill for cuts & pacing > **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q="` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page. Hide a cut inside a frame that is fully covered (a passing object, a dark wall, a blur) to fake one continuous shot. - **Type:** [Effect](https://varg.ai/how-to/effects.md) · [Cuts & pacing](https://varg.ai/how-to/browse/skills/cuts.md) - **Slug:** `invisible-cut` - **Status:** live - **Publisher:** HeyGen (community) - **License:** Apache-2.0 - **Source:** https://github.com/heygen-com/hyperframes/tree/main/registry/components/whip-pan-cut - **Works in:** Claude Code, Claude.ai, Codex, Cursor, OpenClaw, Gemini CLI, Any MCP client, varg Studio - **Requires:** ffmpeg, HyperFrames (npx hyperframes), Remotion, CapCut (by hand) - **Cost:** Free — the take renders locally; generated footage, if any, bills by the model ## What it does Built on [Whip Pan Cut](https://github.com/heygen-com/hyperframes/tree/main/registry/components/whip-pan-cut) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's. The camera passes behind a pillar or into darkness; when it comes out we are somewhere else, with no visible edit. **When:** One-take illusions, travel and transformation reels, product reveals through an object. **Watch out:** If the cover does not fill the whole frame for at least one frame, the edge of the cut flashes. **Timing:** Cut on a fully covered frame; optionally a 2–4 frame crossfade inside the cover **Also called:** hidden cut, seamless cut, stitch cut, one-shot illusion, wipe-by ### In FFmpeg Cut on the fully covered frame and smooth it with a very short fade inside the cover (offset = A length - T): ```bash ffmpeg -i a.mp4 -i b.mp4 -filter_complex \ "[0:v]fps=30,settb=AVTB[a];[1:v]fps=30,settb=AVTB[b];\ [a][b]xfade=transition=fade:duration=0.1:offset=3.9[v]" -map "[v]" out.mp4 ``` ### In HyperFrames Cover-and-cut overlays: `hw-scribble-transition` and `mk-clone-wall-transition` fill the frame, the host cuts beneath, then they clear. Camera versions: `whip-pan-cut`, `zoom-through-transition`. ### In Remotion Use `fade()` with `linearTiming({durationInFrames: 3})` placed exactly on the covered frames, or `TransitionSeries.Overlay` to drop a cover element over the cut without changing timing. ### In CapCut Cut on the dark/covered frame; add a short Mix (0.1–0.2 s) or a mask that follows the passing object if the cover is not perfect. ### Ready-made components - [Whip Pan Cut](https://skills.varg.ai/component/hf.whip-pan-cut/) (hyperframes): npx hyperframes add whip-pan-cut - [Zoom Through Transition](https://skills.varg.ai/component/hf.zoom-through-transition/) (hyperframes): npx hyperframes add zoom-through-transition - [Scribble Transition](https://skills.varg.ai/component/hf.hw-scribble-transition/) (hyperframes): npx hyperframes add hw-scribble-transition - [Text Clone Wall Transition](https://skills.varg.ai/component/hf.mk-clone-wall-transition/) (hyperframes): npx hyperframes add mk-clone-wall-transition - [Push Through](https://skills.varg.ai/component/remocn.push-through/) (remocn): npx shadcn@latest add @remocn/push-through ### Where this comes from - [FFmpeg filters: xfade](https://ffmpeg.org/ffmpeg-filters.html#xfade) - [Remotion: ](https://www.remotion.dev/docs/transitions/transitionseries) - [HyperFrames: compositions](https://hyperframes.heygen.com/concepts/compositions) ## Use when - One-take illusions, travel and transformation reels, product reveals through an object. ## Not for - If the cover does not fill the whole frame for at least one frame, the edge of the cut flashes. ## Install - Claude Code: `claude plugin marketplace add vargHQ/skills && claude plugin install varg@varg` - Codex: `npx skills add vargHQ/skills --skill varg-video-edit-library -a codex -y` - Cursor: `npx skills add vargHQ/skills --skill varg-video-edit-library -a cursor -y` ## Example output https://s3.varg.ai/how-to/previews/69c8fae4041c/take-invisible-cut.mp4 — blur between two shots, with the timeline strip of the edit.
