Aspect ratio

A ratio compares width with height. A 16:9 image is wider than it is tall, while a 9:16 image is vertically oriented. Other formats may be square or use different widescreen proportions. The ratio can describe a camera recording, a finished programme, a screen or a crop. Always identify which one is meant when discussing a production, because a source image and final delivery can use different shapes.

Aspect ratio is separate from resolution. Two frames can share the same ratio but contain different numbers of pixels. A change in aspect ratio may require cropping, adding background space or reframing the image. Cropping removes parts of the original picture, so important faces, captions and visual details should not be placed too close to the edges.

For a project with multiple outputs, decide whether the camera framing should protect a common central area or whether separate compositions will be created. A wide master may not convert neatly to vertical delivery, particularly when subjects move across the frame. Discuss resolution and frame rate alongside aspect ratio so the full recording and delivery plan is clear.

The frame shape affects what can be included and how viewers perceive the scene. A wide frame can accommodate several speakers or a broad environment; a vertical frame may emphasize a single person or an upright subject. Neither format is universally superior. The intended platform, screen and visual purpose should guide the choice.

A mismatch between source and destination can lead to unwanted bars, stretching or cropping. Stretching changes the shape of people and objects, while cropping can remove meaningful action. Letterboxing adds bars within a frame to preserve a wider image; pillarboxing does the same for a narrower image within a wider frame. These may be appropriate choices if agreed and checked on the actual destination.

The table describes common shapes, not universal platform rules. Check the receiving service's current specifications and preview the image in its intended player. Where one shoot must serve several formats, consider separate camera framing, additional coverage or a planned re-edit rather than relying on automatic cropping. Keep titles and lower thirds within the safe area for each version.

A framing guide or overlay can help the camera team preserve alternate crops, but safe areas do not guarantee that every composition will work. A speaker may move off center, or a second person may enter at the edge. Rehearse the action and review the full scene. If the camera records a higher resolution master, that may offer cropping flexibility, but it cannot restore information outside the captured frame.

A production team filming an interview in Abu Dhabi must deliver both a landscape programme and short vertical excerpts. During planning, the team decides whether the interview will be captured with additional space around the speaker or recorded in separate compositions. The choice accounts for the background, microphone placement and where titles will appear.

1. Confirm the required frame shape and pixel dimensions for every destination.
2. Set camera guides for the planned crop and keep essential action inside the usable area.
3. Record a test with the speaker moving naturally, then inspect each intended version.
4. Create and review separate exports rather than stretching one frame to fit another.

The editor can make a vertical cut from the interview only if the speaker remains within a useful crop and no critical visual information is lost. If the framing is too wide or the speaker crosses the frame, a separate take may be more effective. Review subtitles and graphic placement in every output, because text that fits the landscape master may be obscured or clipped in a vertical version. The final exports are checked on a phone and a desktop screen before delivery, not only in the editing timeline.

• Confusing aspect ratio with resolution or pixel count.
• Stretching an image instead of preserving its proportions.
• Cropping a wide master without checking faces, action and titles.
• Assuming one framing will serve every platform equally well.
• Exporting a ratio that has not been tested in the receiving player.

Do not treat bars as automatically incorrect: they may preserve the intended image. The issue is whether the framing is deliberate and the destination supports it. Avoid making delivery decisions from a thumbnail alone. Inspect the complete image at the intended display size and verify that graphics, captions and important movement remain visible.
