A title card or annotation must be readable long enough to do its job. Design review should happen inside the moving sequence, where backgrounds, captions and interface overlays can change the experience.
What you will leave with: Leave with a frame-and-timing review for essential text in one video.
Use this when
- Small text looks good in the editor but fails on phones.
- Captions cover a product label or lower-third graphic.
- A key qualification appears too briefly to read.
This is not a universal safe-area template or a complete video-accessibility assessment.
Identify the text that carries meaning
List every on-screen label, number, name, instruction and qualification. Mark which information is essential and where it is also available through narration or an accessible alternative. Do not rely on a tiny disclaimer to repair a broad spoken claim. If the condition materially changes the promise, integrate it into the explanation. Separate necessary content from decorative typography. A busy frame often needs fewer simultaneous messages rather than a more aggressive font treatment. Decide what the viewer must read before deciding how much the design can contain.
Test the moving background
W3C's media guidance calls attention to readable overlay text and information that should not rely exclusively on vision. Review contrast against the actual frames behind the graphic, including transitions and bright or textured moments. A label may be clear over one shot and disappear over the next. Consider a stable backing or different placement where appropriate. Keep the text large enough for its intended viewing context and test the actual export. Do not treat a desktop preview or a still image as proof that the whole sequence is readable.
Give the viewer enough time
Read the graphic at a realistic pace while watching the sequence, without pausing or knowing the words in advance. Allow for the competing task of understanding the image and speech. Complex numbers or unfamiliar names may need more time than a short familiar phrase. Simplify or split dense content rather than assuming viewers will stop the video. Keep entrance and exit animations from consuming most of the reading window. Ask a fresh reviewer what they could actually read and remember, and treat missed information as a design problem to investigate.
Check the destination frame
Preview the video where it will appear, including captions, player controls and platform overlays. Different aspect ratios or crops may require genuinely adjusted graphics rather than a center crop of one master. Check essential content at narrow sizes and after compression. Keep editable text and version records so a factual correction can be made without rebuilding the entire film. Review names, values and qualifications separately from visual polish. Successful readability means the intended information remains available in context, not that the graphic merely stays inside a template's guide lines.
Make the reasoning concrete.
A hypothetical training video shows a three-step setup while a lower-third identifies the instructor.
Resolve competition
Opening: The editor moves or shortens the lower-third so it does not cover the relevant control or captions.
Hypothesis: Viewers can follow the setup and identify the speaker.
Risk: A visually balanced composition can still obscure essential information.
Preserve qualification
Opening: A condition attached to a numerical example is spoken and displayed clearly.
Hypothesis: The number is less likely to be interpreted without its boundary.
Risk: A fleeting footnote would not provide an equivalent explanation.

Take the questions into your next brief.
Use these prompts in your own notes. Nothing is submitted from this page.
Essential text
Which words or numbers carry necessary meaning?
Alternatives
Where is that information available beyond the graphic?
Background
Does contrast remain adequate throughout the shot?
Timing
Can a fresh viewer read it without pausing?
Destination
What captions, overlays or crops compete with it?
Watch for the wrong conclusion.
- Approving graphics only as still images.
- Using tiny text to qualify a major claim.
- Assuming one safe-area guide fits every destination.
- Letting animation consume the useful reading time.
Your next action
Watch one exported video at its intended display size and record every essential text element that is obscured or too brief to read.
