How to zoom in on a video
Last updated 2026-10-20
To zoom in on a video, scale the clip up so the frame shows only the middle of the picture. That is a static zoom. For a zoom that moves, animate the size with keyframes or add a push-in effect. On 1080p footage, about 150 percent is the practical limit before it turns soft, and 200 percent leaves only 960 by 540 pixels.
Static zoom or animated zoom
A static zoom is one fixed enlargement. The clip is scaled up, and its edges fall outside the frame. Use it for a tighter framing that holds for the whole shot. An animated zoom changes the enlargement over time. It points at something, or adds energy to a flat shot. For still photos, the Ken Burns guide covers the same idea.
iMovie's Crop to Fill is a static zoom. Apple says the area inside an adjustable frame fills the viewer, and that the frame is constrained to 16:9.
| Method | Movement | Best for |
|---|---|---|
| Crop zoom | None, it holds | A tighter shot that stays tight |
| Size keyframes | Any speed you set | A push-in or snap you time yourself |
| Push-in | Slow zoom toward a subject | A slow build on a face or product |
| Punch | Holds, then snaps in | Emphasis on one line |
| Focus Zoom | Zooms in, holds, returns | Pointing at a detail |
| Whip Zoom | Fast crash with a small bounce | A hard reveal, used once |
Punch-ins on a talking head
A jump cut removes a pause or a flub and leaves the speaker in the same spot, so the picture jerks. A tighter framing after the cut changes the shot enough that the jerk reads as an edit you meant. Pick two sizes, such as 100 and 125 percent, and switch between them only at cuts, or tighten only on the lines that need weight.
Small changes look like errors. At 105 percent the viewer sees a wobble, not a new shot. Around 120 to 130 percent the change is obvious. At the default setting, Woven's Punch starts near 118 percent and Push-in near 124 percent.
Two mistakes are common. The first is punching in at every single cut, so nothing stands out. The second is zooming toward the center of the frame, which crops off the top of the head. Aim the zoom at the eyes. Effects never move text or captions, so captions stay put during a punch-in.
What zooming does to resolution
Zooming enlarges pixels you already have. Zoom into 1920 by 1080 footage at 200 percent and only the middle 960 by 540 pixels remain, stretched back to fill the frame.
A 4K clip (3840 by 2160) at 200 percent still shows 1920 by 1080 pixels, so it stays sharp in a 1080p edit. The Zoom slider on Woven's zoom effects tops out between 130 and 150 percent. The Crop tab's slider goes to 400 percent, which few sources can support. Treat the top of the slider as a limit, not a target.
| Zoom | Pixels shown | Width and height kept |
|---|---|---|
| 120% | 1600 by 900 | 83% |
| 150% | 1280 by 720 | 67% |
| 200% | 960 by 540 | 50% |
| 400% | 480 by 270 | 25% |
How far to go
A zoom needs a target: a face, a product, a number on a screen. A zoom with no target looks like a mistake. Finish on a held size for a beat instead of stopping mid-move. Use these as starting points.
- Slow push. Ten to twenty percent across a long shot, so it is felt and not noticed.
- Punch-in. 120 to 130 percent, at a cut or on a key line.
- Emphasis zoom. Focus Zoom or Punch on one line, then return to the wide shot.
- Crash zoom. Near the effect's maximum, once per video.
Zoom in Woven
Woven has three routes: the Zoom slider in a clip's Crop tab for a fixed zoom, Size keyframes for one you time yourself, and zoom effects that animate for you. Only one effect is active at a time, so when effects overlap, the one that starts last wins.
Ask in chat
- Punch in to 125 percent on the second half of this clip.
- Add a slow push-in on the product shot, aimed at the label.
- Alternate wide and tight at every cut in the interview.
- Add a whip zoom on the reveal at 12 seconds.
Or do it by hand
- 1Split at the cut. Put the playhead on the cut and press ⌘B, so the part you want tighter is its own clip.
- 2Fixed zoom. In the Crop tab, slide Zoom under Framing to the size you want, such as 125 percent. Double-clicking the clip on the canvas then lets you drag the zoomed picture until the eyes sit high in the frame.
- 3Moving zoom. Choose Add, then Video Effects, and click + on Push-in, Punch, Focus Zoom or Whip Zoom. Drag the effect's edges on the Effects track to set its length.
- 4Aim it. Click the effect on the Effects track. On the Framing page, pull the focal point onto the face, then set the Zoom percentage. Reset framing returns the point to the center and the zoom to its default.
- 5Check the softness. Play it back and look at the tightest frame. If it looks soft, lower the zoom.
Common questions
Scale the clip up and move it so the part you want stays in the frame. In Woven, the Zoom slider in the Crop tab does this, up to 400 percent.
Apple describes Crop to Fill, which shows an adjustable frame over the clip. The area inside it fills the viewer, and the frame is constrained to 16:9.
A quick zoom into part of the shot, often at a cut, for emphasis or to hide a jump cut. In Woven, the Punch effect holds, then snaps into the zoom.
An enlargement that changes over time, such as a slow push-in or a fast whip zoom. Woven has Push-in, Punch, Focus Zoom and Whip Zoom.
Yes, because only the middle pixels are kept. At 200 percent, 1080p footage keeps 960 by 540 pixels. 4K footage stays sharp at 1080p up to 200 percent.
Use Focus Zoom, which zooms toward a detail, holds, then returns. Drag its focal point onto the detail.
