Definition
Aspect ratio describes the proportional relationship between a video's width and height, written as width:height. A 16:9 video is wider than it is tall; a 9:16 video is vertical. Choosing a ratio affects framing and cropping, so keep important interface details and captions inside the visible safe area.
Scenario in a product workflow
A product screen composed for 16:9 may place a sidebar and explanatory caption across a wide frame. In 9:16, those elements need a different composition and may require a shorter sequence. Preview each export instead of assuming a center crop keeps controls and text readable.
How to apply it
Select the destination and placement first. Recheck the composition at that ratio because interface details, subtitles and end cards can move near crop or overlay areas.
A practical review
Create a separate preview for every intended placement. Inspect corners, subtitle safe areas, interface overlays and end cards after reframing. Do not rely on a center crop when the product UI or pointer is near an edge.
A decision to make before production
Choose the frame for the destination before composing the screen capture. If the same story must serve portrait and landscape placements, plan a reframe or alternate scene layout instead of shrinking the entire interface.
How it differs from resolution
Aspect ratio describes the shape of a frame, such as 16:9. Resolution describes its pixel dimensions, such as 1920 × 1080. Two files can share a ratio while having different resolutions.
When a team uses the term “aspect ratio” in a brief or review, agree on the intended meaning before production. That prevents the script, visual plan and success measure from drifting apart.
