# Glitch — effect skill for transitions

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` 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.

The frame tears into displaced slices, colour channels split and noise flickers as A breaks into B.

## What it does

Built on [Glitch](https://github.com/heygen-com/hyperframes/tree/main/registry/blocks/glitch) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Horizontal slice offsets, RGB fringes, block noise and a flicker for a few frames around the cut.

**When:** Tech, gaming, cyber, music and edgy fashion pieces; "signal lost" moments.

**Watch out:** Corporate or calm content; long glitches stop reading as an artefact.

**Timing:** 0.2–0.5 s (CapCut Glitch 0.47 s, RGB Glitch 1.0 s); keep under ~20 frames

**Also called:** Glitch, RGB Glitch, Color Glitch, Urban Glitch, Signal Glitch 2, TV Flickers, digital glitch, datamosh

### In FFmpeg

Hard cut with RGB split + temporal noise for 0.3 s around it (both filters support `enable`):
```bash
ffmpeg -i a.mp4 -i b.mp4 -filter_complex \
"[0:v]trim=0:4,setpts=PTS-STARTPTS[x];[1:v]trim=0:4,setpts=PTS-STARTPTS[y];\
 [x][y]concat=n=2:v=1:a=0,\
rgbashift=rh=-24:bh=24:enable='between(t,3.85,4.15)',\
noise=alls=60:allf=t:enable='between(t,3.85,4.15)'[v]" -map "[v]" out.mp4
```
Add `xfade=transition=pixelize` or `hlslice` for blockier tearing.

### In HyperFrames

Shader `glitch` from `@hyperframes/shader-transitions` placed at the cut (t = 4 s):
```html
<div id="s1" class="scene" style="background:#0a0a0a"><video src="a.mp4" muted playsinline></video></div>
<div id="s2" class="scene" style="background:#0a0a0a"><video src="b.mp4" muted playsinline></video></div>
<script src="https://cdn.jsdelivr.net/npm/@hyperframes/shader-transitions/dist/index.global.js"></script>
<script>
  const tl = HyperShader.init({ bgColor: "#0a0a0a", scenes: ["s1", "s2"],
    transitions: [{ time: 4, shader: "glitch", duration: 0.5 }] });
  window.__timelines = window.__timelines || {}; window.__timelines["main"] = tl;
</script>
```
Each `.scene` needs an explicit background-color equal to `bgColor`. Or install the ready block: `npx hyperframes add glitch`.

### In Remotion

remocn `glitchCut()` presentation, 12 frames recommended:
```tsx
import {glitchCut} from '@/components/remocn/glitch-cut';
<TransitionSeries.Transition timing={linearTiming({durationInFrames: 12})} presentation={glitchCut()} />
```
It needs HTML-in-canvas for the full effect (CSS fallback elsewhere); render with `--gl=angle`. GL: `GlitchMemories`, `GlitchDisplace`, `StripDatamoshGlitch`.

### In CapCut

Transitions tab → Glitch → Glitch, RGB Glitch, Color Glitch, Urban Glitch, Signal Glitch 2, TV Flickers. Desktop: drag the tile onto the cut between two clips and set Duration in the right panel ("Apply to all" reuses it on every cut). Mobile: tap the small white square between clips, pick the transition, drag the duration slider, tap ✓. Tab labels and placement change between versions and regions.

- [Mix (Cross Dissolve)](https://varg.ai/how-to/skills/mix-dissolve.md): The two shots blend through each other. The quietest transition: "time passes" or "this continues".
- [Dip to Black](https://varg.ai/how-to/skills/black-fade.md): A fades to black, then B fades up. Marks the end of a section or a bigger jump in time.
- [White Flash](https://varg.ai/how-to/skills/white-flash.md): The frame blows out to white for a moment and opens on the next shot. Energy, memory or a camera snap.
- [Pull In (Zoom In)](https://varg.ai/how-to/skills/pull-in-zoom.md): The camera rushes into shot A and lands, still moving forward, in shot B. The signature short-form transition.
- [Pull Out (Zoom Out)](https://varg.ai/how-to/skills/pull-out-zoom.md): The camera jerks backwards out of shot A and keeps pulling back as shot B settles in.
