Chromatic Split — 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).

Red, green and blue channels pull apart around the cut, then snap back together on the new shot.

What it does

Built on Chromatic Aberration Wipe by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Colour ghosts offset horizontally or radially for a few frames, with a slight zoom.

When: Fashion, music, tech promos; as a lighter alternative to a full glitch.

Watch out: Large offsets on text; keep the split brief.

Timing: 0.2–0.5 s; peak offset on the cut

Also called: RGB split, chromatic aberration transition, colour fringe, Rainbow Warp

In FFmpeg

Channel split ramping around a cut (rgbashift supports runtime enable; offsets are fixed per window, so stack 2 windows for a ramp):

ffmpeg -i a.mp4 -i b.mp4 -filter_complex \
"[0:v][1:v]concat=n=2:v=1:a=0,\
rgbashift=rh=-10:bh=10:enable='between(t,3.8,3.9)+between(t,4.1,4.2)',\
rgbashift=rh=-30:bh=30:gv=6:enable='between(t,3.9,4.1)'[v]" -map "[v]" out.mp4

In HyperFrames

Shader chromatic-split from @hyperframes/shader-transitions placed at the cut (t = 4 s):

<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: "chromatic-split", 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 chromatic-radial-split. Slide variant: npx hyperframes add chromatic-aberration-wipe.

In Remotion

Custom presentation rendering three copies of children with mixBlendMode: 'screen', tinted R/G/B via CSS filters and offset by presentationProgress; or @remotion/effects/chromatic-aberration on a canvas-based <Video>.

In CapCut

Transitions tab → Glitch / Distortion → RGB Glitch, Rainbow Warp. 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. Or Effects → Video effects → an RGB split effect for a few frames.
