Punch-in
Also known as: digital punch-in, zoom in edit, crop zoom in post
Zooming into a clip in the edit, either as a sudden cut to a tighter frame or a smooth push, to emphasize a moment or create a second angle.

What it means
A punch-in enlarges part of a clip in editing. A hard punch-in jumps instantly from the original framing to a tighter crop, often on a beat or a punchline, which is common in vlogs and comedy. A smooth punch-in uses keyframes to push in gradually, adding tension or focus.
It is also a practical trick. With high-resolution footage, a punch-in creates a second shot size from a single camera, which helps hide jump cuts in talking shots and adds variety to action sequences.
Every punch-in is a form of digital zoom, so it spends resolution you cannot get back.
How it works in practice
Record at 4K or higher if you plan to deliver in 1080p, so you can punch in up to about two times without visible softening. A 4K delivery leaves less room, unless you recorded in 5.3K or more.
Use hard punch-ins on beats, reactions or punchlines, and keep them modest, around 110 to 130 percent. For action, a slow push-in toward the takeoff of a jump builds anticipation before the big moment.
Combine a punch-in with stabilization: tighter frames magnify shake, so smooth footage matters more. A little extra smoothing before punching in keeps the result clean.
What to watch out for
Punching in too far on low-resolution or heavily compressed footage makes it soft, noisy and blocky. Check the result at full screen on a large display, not just in the small preview window.
Repeated punch-ins become a tic. Use them where they add meaning, not on every sentence or clip, or viewers start to notice the technique instead of the content.
Wide-angle distortion near the edges of action camera footage can look odd when you crop toward an edge. Keep punch-ins near the center of the frame for the most natural look, and watch for artifacts that become visible when enlarged.
How RawClip handles it
RawClip uses your clips at their recorded framing and delivers the highlight in 4K and 1080p. The 4K version gives you room to add punch-ins later if you edit further, starting from your finished highlight.
