Most clipping advice is about judgement — what to cut, how to hook. This one is about the boring settings that quietly decide whether your good edit actually looks good in the feed. Get them wrong and a strong clip arrives soft, cropped, or with its caption hidden behind a button. Get them right once and you never think about it again.
Aspect ratio: 9:16, always
Vertical short-form lives at a 9:16 aspect ratio — taller than it is wide, filling a phone screen top to bottom. Every major short surface is built for it.
Export anything else and you pay for it. A square clip leaves empty bars above and below. A landscape clip gets either letterboxed into a small strip or awkwardly cropped. Both signal "this was made for somewhere else," and both waste the screen real estate that vertical gives you for free. If your source footage is horizontal, you reframe it to vertical rather than dropping it into a 9:16 canvas with black bars — more on that below.
Safe zones: keep the good stuff centred
This is the spec clippers most often miss. The full 9:16 frame is not fully visible. Each app lays its own interface over the edges:
- The right side holds like, comment, share, and profile buttons.
- The bottom holds the caption, the audio label, and the account name.
- The very top can carry a status bar or a following/for-you toggle.
Anything important that sits under those areas gets covered. A face tucked into the bottom-left, a caption line that runs to the bottom edge, a key detail pinned right — all at risk.
| Zone | What lives there | Your content |
|---|---|---|
| Centre | Nothing from the app | Faces, action, the point of the clip |
| Right edge | App buttons | Keep clear |
| Bottom | Caption, audio, handle | Keep your own captions above it |
| Top | Status / feed toggle | Avoid pinning text here |
The rule of thumb: imagine a margin around the frame and keep faces and your own captions inside it. When you place captions, sit them in the middle third vertically, not jammed to the bottom where the app's own text lives. Caption craft beyond placement is in captioning for retention.
Resolution: export high, always
Exporting at a high resolution — commonly 1080 by 1920 for vertical — does not magically sharpen weak source footage, but exporting low throws away quality you actually had. Platforms compress everything on upload, so you want to hand them the cleanest possible file to compress from. Start soft and the result is blocky; start sharp and it survives compression far better.
A blurry clip loses viewers in the first second regardless of how good the moment is. Technical sharpness is table stakes for holding attention.
Reframing horizontal source to vertical
A lot of clippable material — interviews, gameplay, panels — is filmed horizontal. Do not paste it into a vertical frame with black bars top and bottom; that leaves a tiny centre strip and looks unfinished. Instead:
- Crop and reframe to follow the subject, so the person or action fills the vertical frame.
- Use a split or stacked layout when two things matter at once — a common approach for gameplay with a facecam, or two speakers.
- Punch in on the speaker at the moment they matter, keeping their face in the safe centre.
The goal is a frame that feels made for vertical, not squeezed into it.
A quick pre-export checklist
- Aspect ratio 9:16. No square, no landscape, no bars.
- Resolution high. Export at the best your editor offers, typically 1080 by 1920.
- Faces centred. Nothing important under the app's buttons or bottom bar.
- Captions in the safe middle. Above the app's own caption line, clear of the right-side buttons.
- No leftover watermark. A recycled-looking export can dampen reach — see watermarks kill reach.
Getting these right is invisible when you do it and obvious when you do not. It is the floor your editorial work stands on. Once the spec is handled, the craft — hooks, pacing, moment selection — is what does the heavy lifting; see how to edit a viral clip and the multi-platform clipping workflow for adapting one master across surfaces.
A sharp, well-framed clip protects watch-through, but reach turning into views is never guaranteed — what you earn depends on the views your clips receive at a program's rate. Results vary and this is not financial advice.
