Choose the composition from the job
| Shape | Example dimensions | Useful when |
|---|---|---|
| 16:9 horizontal | 1920 × 1080; 3840 × 2160 | People, action or graphics need width; a desktop or physical widescreen is the main viewing space. |
| 9:16 vertical | 1080 × 1920 | A full-height phone presentation is primary; one person or a vertically arranged action fits naturally. |
| 1:1 square | 1080 × 1080 | The selected feed placement and creative benefit from a balanced central composition. |
| 4:5 portrait | 1080 × 1350 | A taller feed placement is specified without requiring a full 9:16 frame. |
These are planning examples, not universal upload requirements. Advertising placements, page layouts and platform interfaces change. YouTube’s official aspect-ratio guidance explains that its player adapts to different shapes and advises against baking padding into the file. Confirm the exact placement instead of adding black bars by habit.
What a centre crop actually removes
Take a 3840 × 2160 horizontal recording. A full-height 9:16 crop is only 1215 pixels wide: 2160 × 9 ÷ 16. It retains about 31.6% of the original width. Almost two-thirds of the horizontal scene sits outside that crop.
That crop has enough source pixels to scale down to 1080 × 1920. But a person at the left and a product at the right cannot both remain visible unless they fit inside the narrow selected area. Reframing can follow one subject; it cannot show two separated subjects at once.
From a 1920 × 1080 source, the same crop is approximately 608 × 1080. Exporting it at 1080 × 1920 requires enlargement. Depending on the footage and destination, that may reveal softness or compression. The resolution guide separates those pixel limits from composition.
One deliberately shared composition
This can work for a single seated speaker or a compact demonstration. Display framing guides during the test and keep the essential action inside the planned vertical area. Check hands, props and headroom, not just the face.
The horizontal version may need a carefully chosen background to avoid feeling empty. Do not centre every shot automatically; choose the compromise because it works for both pieces.
Separate takes for repeatable action
Record the explanation or product action horizontally, then adjust the camera and blocking for a vertical take. Use the same approved wording and continuity details. This often produces stronger compositions than forcing both outputs from one frame, but requires time in the shot plan.
It is suitable for controlled demonstrations, presentations to camera and some portraits. It is inappropriate to ask for a genuine event reaction or an unsafe operational task to be repeated merely for a new orientation.
Separate cameras for an unrepeatable moment
If a ceremony, event or live demonstration needs both formats, a second planned view can protect the vertical output. Decide who monitors it and whether a static position can cover the action. More cameras add recording, synchronisation and editing work; they do not eliminate staffing limits.
Test one finished sample before the filming day
Make a short example with the intended subject position, captions and logo. View it at the actual phone or display size. Check whether interface overlays hide text, whether the action remains clear and whether the final frame gives the viewer a useful next step.
Supply the camera team with the primary orientation, required alternative versions and a screenshot of the real placement. That small decision belongs in the brief. It is much cheaper to move a chair before recording than discover in the edit that the second speaker disappears.
