Wipe — effect skill for transitions

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/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://skills.varg.ai/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.

A moving edge replaces A with B across the frame while both images stay still.

What it does

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

A straight (or soft) line travels across; on one side A, on the other B.

When: Classic "meanwhile", retro TV, comparisons and before/after.

Watch out: Diagonal and corner wipes in serious content can look dated.

Timing: 0.4–0.8 s (CapCut Wipe Left/Right 0.47 s), linear or ease-in-out

Also called: Wipe Left, Wipe Right, Wipe Up, linear wipe, edge wipe

In FFmpeg

Same size/fps/pixel format on both inputs (see the Normalize card). offset = duration(A) - T = 5.0 - 0.5 = 4.5.

ffmpeg -i a.mp4 -i b.mp4 -filter_complex \
"[0:v]fps=30,settb=AVTB,format=yuv420p[a];[1:v]fps=30,settb=AVTB,format=yuv420p[b];\
[a][b]xfade=transition=wipeleft:duration=0.5:offset=4.5[v];\
[0:a][1:a]acrossfade=d=0.5[au]" \
  -map "[v]" -map "[au]" -c:v libx264 -crf 18 -c:a aac out.mp4

Others: wiperight, wipeup, wipedown, wipetl/wipetr/wipebl/wipebr, diagtl…diagbr, smoothleft… (soft edge).

In HyperFrames

Clip-path wipe on the incoming wrapper:

tl.fromTo("#s2", { clipPath: "polygon(0 0,0 0,0 100%,0 100%)", opacity: 1 },
  { clipPath: "polygon(0 0,100% 0,100% 100%,0 100%)", duration: 0.5, ease: "power2.inOut" }, T);

Comparison divider: before-after-wipe.

In Remotion

import {TransitionSeries, linearTiming, springTiming} from '@remotion/transitions';
import {wipe} from '@remotion/transitions/wipe';

<TransitionSeries>
  <TransitionSeries.Sequence durationInFrames={90}><ShotA /></TransitionSeries.Sequence>
  <TransitionSeries.Transition presentation={wipe({direction: 'from-left'})} timing={linearTiming({durationInFrames: 20})} />
  <TransitionSeries.Sequence durationInFrames={90}><ShotB /></TransitionSeries.Sequence>
</TransitionSeries>

Total = 90 + 90 - 20 frames: the transition overlaps the two shots. wipe() directions include diagonals: from-top-left, from-top-right, from-bottom-left, from-bottom-right.

In CapCut

Transitions tab → Slide / Basic → Wipe Left, Wipe Right, Wipe Up. 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.
