Hide a jump cut by scaling the next segment 110–130%. Reads as a second camera angle in talking heads.

## What it does

Built on [Camera Punch-In](https://github.com/heygen-com/hyperframes/tree/main/registry/components/yt-camera-move) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

After the cut the same shot is suddenly tighter (or wider), so the jump feels like a deliberate camera change.

**When:** Every 2–3 jump cuts in a talking head, on emphasis words, punchlines or a change of point.

**Watch out:** Punching past ~130% on 1080p footage shows softness; alternate in and out rather than zooming tighter every time.

**Timing:** Instant (0 frames) or a 3–6 frame ease into the new scale

**Also called:** punch-in, zoom cut, digital zoom cut, punch in on a jump cut

### In FFmpeg

Static 125% punch-in on the second segment (crop keeps the centre, scale restores the size):
```bash
ffmpeg -i take.mp4 -filter_complex \
"[0:v]split[p][q];\
 [p]trim=0:2.5,setpts=PTS-STARTPTS[w];\
 [q]trim=2.5,setpts=PTS-STARTPTS,crop=iw/1.25:ih/1.25,scale=1920:1080,setsar=1[t];\
 [w][t]concat=n=2:v=1:a=0[v]" -map "[v]" -map 0:a out.mp4
```
`crop` evaluates w/h only once, so for an animated push use `scale=w='...t...':h=-2:eval=frame,crop=1920:1080` or `zoompan=...:d=1`.

### In HyperFrames

Tween the inner wrapper, never the timed clip:
```js
tl.set("#seg2 .inner", { scale: 1.25 }, 2.5);           // instant punch
// or eased: tl.fromTo("#seg2 .inner", {scale:1.1}, {scale:1.25, duration:0.15, ease:"power2.out"}, 2.5);
```

### In Remotion

```tsx
<Series.Sequence durationInFrames={75}>
  <AbsoluteFill style={{transform: 'scale(1.25)'}}><Video src={take} trimBefore={75} /></AbsoluteFill>
</Series.Sequence>
```
`pushCut()` from `@remotion/transitions/push-cut` (v4.0.500+) is a ready hard cut with a short punch-in and a 2-frame flash.

### In CapCut

Select the segment after the split → Basic → Scale (e.g. 125%), or add Position/Scale keyframes for an eased push.
