> TL;DR: A punch-in zoom scales your shot slightly, usually 10 to 18 percent, to emphasise a line or hide a jump cut. Use one every few sentences on the lines that carry the point, keep your face in frame, and stay small on 1080p footage. In Vidiyo, ask "punch in on the key lines"; by hand, keyframe the clip's scale.

A [punch-in zoom](https://getvidiyo.app/glossary/punch-in-zoom) is the cheapest second camera there is. You shot one wide-ish frame; in the edit you make part of it tighter, and suddenly the video has two angles. Used on the right lines, it adds emphasis and hides jump cuts. Used on every cut, it turns into noise. Here's how to get the amount, the placement and the technique right.

## What is a punch-in zoom in a talking-head video?

A punch-in zoom is a jump to a tighter framing of the same shot, made by scaling the video up in the edit rather than moving the camera. On a talking head it does two jobs: it emphasises the line it lands on, and it disguises a jump cut by making it look like a cut between two cameras.

There's also a slower cousin, the push-in, where the scale grows gradually over a line. The punch-in is a cut; the push-in is a move. Both are [keyframes](https://getvidiyo.app/glossary/keyframe) on the clip's scale and position.

## How much should you punch in?

Punch in about 10 to 18 percent. That's enough for the change to read as a new framing, and small enough that the picture stays sharp and your face stays whole. On 1080p footage, stay at or below 20 percent, because you're enlarging pixels. Footage shot in 4K leaves more room, since the export is 1080p.

| Scale | Effect | When to use |
|---|---|---|
| 100% | Base framing | Most of the video |
| 110 to 118% | Clear but subtle punch-in | Key lines, alternate jump cuts |
| Up to 120% | Strong emphasis | A single big moment on 1080p footage |
| Above 120% | Noticeably soft on 1080p | Only with higher-resolution sources |

Position matters as much as scale. When you scale up, re-centre so your face stays in the upper middle of the frame, with your eyes around a third from the top. A punch-in that crops your forehead looks like a mistake.

## Where should punch-ins go?

Put punch-ins on the lines that carry the point: the hook, a number, a strong claim, a punchline, a turn in the story. Roughly one every two to four sentences is a good rhythm. Add them at raw jump cuts too, alternating normal and tight framing, so cuts read as deliberate.

Avoid punch-ins on:

- Every single cut. The emphasis stops meaning anything.
- Screen recordings and product UI. Scaling hides controls and text.
- Picture-in-picture or split layouts, where the speaker is already in a small frame.
- Lines where you gesture widely, since a tight frame cuts off your hands.

## How do I add punch-in zooms in Vidiyo?

Ask the assistant which lines to punch in on, or let it choose. It splits each line out of the clip by its words, scales it with your measured face kept centred, and checks the result for a cropped face. Every punch-in is a normal keyframe you can change by hand.

1. Tighten the cut first, so punch-ins land on final timing.
2. Ask "punch in on the key lines", or name them: "punch in on 'we shipped it in a week'".
3. For a slow move, ask "push in slowly over the last sentence". That's a push-in instead of a cut.
4. To hide jumps, ask "punch in on alternate cuts". Vidiyo's quality checks flag raw jump cuts with identical framing, so the assistant knows where they are.
5. Check the result. The assistant uses 10 to 18% by default and stays at or below 1.2x on 1080p sources, and its checks flag a cropped face.

You can also do it without chat. Select the clip, put the playhead where the line starts and open **Camera moves** in the inspector: **Punch in here** jumps to 1.15x from that frame, **Reset here** returns to the original framing, and **Push in** adds a slow 8% push over three seconds. They're ordinary framing keyframes, so you can change them later. More in [layers and keyframes](https://getvidiyo.app/features/layers-and-keyframes).

## How do I add punch-in zooms in other editors?

Split the clip at the start and end of the line, then raise the scale of the middle piece. That's a punch-in in any traditional editor. For a push-in, add two scale keyframes instead: 100% at the start of the line and around 110% at the end, with an ease so it doesn't start abruptly.

1. Place the playhead at the first word of the line and split. Do the same after the last word.
2. Select the middle piece and set its scale to about 110 to 118%.
3. Adjust its position so your eyes sit in the same part of the frame as before.
4. Check the top and bottom edges for a cropped forehead or chin.
5. For a push-in, keyframe scale from 100% to about 110% across the line instead of splitting.
6. Play the section at full speed; the punch-in should feel like a camera change, not a zoom.

## How do punch-ins work in vertical video?

They work the same way, but the room is tighter. In a 9:16 talking head your face often already fills the upper part of the frame, so a large punch-in quickly crops your head. Stay toward the low end of the range, and keep your eyes near the upper third so captions still have space below your chin.

Vertical video also has the platform interface to think about: the app draws buttons and text over the top and bottom of the frame. A punch-in that pushes your face up can push it under that interface. Check punched-in frames on a phone, or at least against a [safe zone](https://getvidiyo.app/glossary/safe-zone) overlay.

In Vidiyo, captions are placed after punch-ins using the measured face position, and the checks flag captions over a face or under the Reels, TikTok and Shorts interface. If a punch-in pushes a caption into trouble, the assistant sees the finding and moves the caption.

## What are common punch-in mistakes?

The common mistakes are zooming too far, zooming too often and zooming on the wrong line. Too far makes 1080p footage soft and crops your face. Too often makes the video feel restless. On the wrong line, the zoom says "this matters" about something that doesn't.

Two smaller ones: forgetting to re-centre after scaling, so your head drifts toward an edge, and stacking a transition on top of a punch-in, which doubles the effect. If you use a zoom blur transition, use it for a change of section, and let ordinary punch-ins be plain cuts.

## Honest limits

- Zooms are keyframed punch-ins and pushes; there's no cursor-follow or face-tracking zoom.
- Export is 1080p at 30 fps, so large zooms on 1080p sources lose sharpness.

## Frequently asked questions

### What is a punch-in zoom?

A punch-in is a cut or quick push to a tighter framing of the same shot, made by scaling the video up in the edit. In talking-head video it adds emphasis on a line and hides jump cuts by making them look like a change of camera angle.

### How much should I zoom in for a punch-in?

About 10 to 18 percent is enough to read as a new framing. On 1080p footage, staying at or below 20 percent avoids visible softness; 4K footage leaves more room because the export is 1080p.

### How often should I punch in?

On the lines that carry the point: the hook, a number, a claim, a punchline. Roughly one every two to four sentences works for most talking heads. On every cut, the effect stops meaning anything.

### What's the difference between a punch-in and a push-in?

A punch-in jumps to the tighter framing on a cut. A push-in moves there slowly over a line, like a camera creeping forward. Punch-ins add energy; push-ins add tension or intimacy.

### Can Vidiyo zoom to follow my cursor in a screen recording?

No. Vidiyo's zooms are keyframed punch-ins, and the assistant doesn't use punch-ins on screen recordings or product UI. There's no cursor-follow zoom.
