Build meaning that survives without audio
A viewer may encounter an ad in a quiet office, on transit, or with audio unavailable. Captions and purposeful on-screen text help carry essential meaning, but they should be concise enough that the screen does not become a dense transcript.
Write dialogue and visuals so the core idea remains understandable without relying on music cues or an unexplained sound effect. If a sound changes the meaning, provide a text cue or another visual signal that conveys the same information.
Keep text legible in the real frame
Preview every aspect ratio and placement at realistic screen size. Captions can collide with platform controls, subtitles may cover product details, and a carefully designed title can disappear when a vertical crop centers on the wrong part of the frame.
Use adequate contrast, sensible line lengths, and a safe area appropriate to the destination. Avoid flashing transitions or rapid overlays that make a short asset harder to follow, particularly when the viewer needs time to read a claim.
Make access a creative constraint
Accessible video does not mean adding a checklist after the edit. Script, framing, speaker pace, caption style, and information hierarchy can all be planned together so the campaign feels deliberate in both sound-on and sound-off contexts.
For a Dynamic Video Campaign, include caption review and device QA in each version’s acceptance criteria. That gives every audience variant a better chance of communicating its intended point rather than treating accessibility as an optional master-file enhancement.
From perspective to practice.
