How long should the final product-ad message remain on screen?

Start With the Actual Message

Write the final message exactly as it will appear, including the product name, offer condition, action, and any required qualifier. Count the rendered words rather than estimating from the design brief. A short phrase such as “See the full size guide” may be readable sooner than a longer message containing a product name and qualification.

Treat each language as its own layout. Translation can change word length, line breaks, and visual density, so the original-language timing cannot simply be copied. Keep the product visible while the CTA is shown; a readable instruction is not useful if the final frame hides the item or its relevant detail.

1. Freeze the exact CTA copy and list every language version.
2. Render each version in its intended font size, line count, contrast, and safe area.
3. Run a phone reading test at normal viewing distance without pausing.
4. Check whether the product, action, and any qualifier remain visible together.
5. Record the first unbriefed response for each current language/layout. Revise a missed action or condition, then document the new version and who reviewed it; do not claim a population-wide slowest-reader result.

Use a Phone Reading Test

The test should reproduce the delivery context as closely as possible: the final frame should appear after the preceding shot, on a phone, at the intended crop. Ask a reviewer who did not write the line to read it once and state the action. Do not prompt them by explaining the message beforehand.

Record two observations separately: whether the words were read, and whether the meaning was understood. A viewer may technically finish the sentence but miss a small condition, a changed product variant, or the action button area. If either observation fails, the ending needs more time, simpler copy, clearer hierarchy, or a different final frame.

Record the layout and the first reading

Keep one row for each language and final layout. Record the exact message, export revision, visible interval, crop and phone orientation. Before any explanation, ask what action and condition the viewer understood; a paraphrase can test meaning without turning the exercise into a speed-reading contest.

This proposed check provides layout observations, not a population reading speed, accessibility certification or advertising result.

Diagnose Before Adding Seconds

Extra time is not always the correct repair. If the text is crowded, increasing duration leaves a crowded frame on screen for longer. First remove nonessential words, separate the action from the qualifier, or improve contrast. If the product disappears behind the text, change placement or the background treatment before extending the hold.

For an CartVisual workflow, planning and review determine the brief; CartVisual does not publish the video to stores or prove that a CTA performs. The current storyboard layout supports 9, 16 or 25 planned shots. Check the selected models, available settings and stage quotes in the workspace; the current product video overview describes the workflow. Those production choices do not establish a universal CTA reading duration. For the distinct opening task, use product recognition versus later brand attribution; a readable final CTA cannot repair an unidentified opening.

1. If reading fails but the frame is clear, simplify the copy or add hold time.
2. If comprehension fails, expose the product and action more clearly.
3. If one language fails, revise that localized layout rather than averaging all timings.
4. Treat a repeat check as a check of that version, not proof about the slowest person in the audience. Include an unbriefed reviewer who has not memorized the line, record any missed qualifier, and revise the actual layout when a reading problem remains.

Worked Exercise: A Fictional CTA

Fictional example: a 15-second product clip ends with “Choose your finish and see the full size guide.” The team initially leaves the line visible for 0.5 seconds. On a phone replay, the reviewer reads only “Choose your finish.” The message therefore fails even though the frame is visually attractive.

The team tests a shorter version, “Choose a finish. See the size guide.” It remains in two lines and keeps the product beside the copy. In this invented exercise an unbriefed reviewer states the action and size-guide request after one normal playback. If the same person has memorized the first version, label a repeat observation accordingly rather than presenting it as a new first reading. The chosen hold is a fictional layout decision, not a platform requirement or audience-performance result.
