# Slide / Push — 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.

B pushes A out of frame (push), slides over it (cover) or A slides away to reveal B (reveal).

## What it does

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

Hard-edged panels move in one direction; reads like swiping between cards or pages.

**When:** Lists, steps, app demos, editorial and corporate explainers; "next point".

**Watch out:** Mixing directions randomly; keep one direction for "forward".

**Timing:** 0.3–0.5 s (CapCut Slide/Left/Right 0.47 s), power3.inOut

**Also called:** Slide, Left, Right, Up, Push Away 2, push transition, cover, reveal

### In FFmpeg

Same size/fps/pixel format on both inputs (see the Normalize card). offset = duration(A) - T = 5.0 - 0.4 = 4.6.
```bash
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=slideleft:duration=0.4:offset=4.6[v];\
[0:a][1:a]acrossfade=d=0.4[au]" \
  -map "[v]" -map "[au]" -c:v libx264 -crf 18 -c:a aac out.mp4
```
Push = `slideleft|slideright|slideup|slidedown`; cover = `coverleft…coverdown`; reveal = `revealleft…revealdown`; soft-edged wipe = `smoothleft…`.

### In HyperFrames

```js
tl.to("#s1", { x: -1920, duration: 0.5, ease: "power3.inOut" }, T);
tl.fromTo("#s2", { x: 1920, opacity: 1 }, { x: 0, duration: 0.5, ease: "power3.inOut" }, T);
```
Blocks: `directional-wipe`, `transitions-push`, `transitions-cover`; elastic: `rubber-band-bumper`.

### In Remotion

```tsx
import {TransitionSeries, linearTiming, springTiming} from '@remotion/transitions';
import {slide} from '@remotion/transitions/slide';

<TransitionSeries>
  <TransitionSeries.Sequence durationInFrames={90}><ShotA /></TransitionSeries.Sequence>
  <TransitionSeries.Transition presentation={slide({direction: 'from-right'})} timing={springTiming({config: {damping: 200}, durationInFrames: 15})} />
  <TransitionSeries.Sequence durationInFrames={90}><ShotB /></TransitionSeries.Sequence>
</TransitionSeries>
```
Total = 90 + 90 - 15 frames: the transition overlaps the two shots.
`slide()` is also the default presentation; directions: from-left, from-right, from-top, from-bottom.

### In CapCut

Transitions tab → Slide → Slide, Left, Right, Up, Push Away 2, Corner Slide. 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.
