Accessible Social Video Checklist for Small Businesses

An accessible video is not a separate version made at the end. The strongest workflow builds access into the script, framing, sound and review from the beginning. That makes the final piece clearer for more viewers and easier to adapt across a website, YouTube and social platforms.

Start with the information, not the effects

Before filming, write the one thing a viewer should understand or do. Then check whether that message still works in three conditions: without sound, without seeing every visual detail and without reading small text quickly. If any condition removes essential information, plan an alternative before production.

This is especially important for short videos built around a reveal, a product demonstration or a person speaking over supporting footage. The audience should not need one sensory channel alone to understand the offer, deadline or next step.

1. Caption speech and meaningful sound

W3C’s Web Content Accessibility Guidelines require captions for prerecorded audio content in synchronized media at Level A.^[1] Captions include more than dialogue when another sound is needed to understand the video. Speaker identification, a door closing, laughter or an alarm may matter to the meaning.

Write captions from the final audio, not an early script. Keep them synchronized, proof names and technical terms, and place them where they do not cover faces, products or essential on-screen information. W3C notes that captions should not obstruct relevant visual information.^[2]

2. Review automatic captions

Automatic captioning is a useful starting point, not a finished approval step. YouTube says automatically generated captions can misrepresent speech because of pronunciation, accents, dialects or background noise, and recommends reviewing and editing them.^[3]

Use a short review list: spelling, punctuation, speaker changes, numbers, addresses, product names and the timing of each line. If the video exists in English and French, review each language as its own deliverable instead of assuming an automatic translation carries the same tone or detail.

3. Make important text readable

Avoid placing essential information in a thin font over moving footage. W3C recommends considering font family, size and the contrast between text and its background.^[4] A solid or partially opaque text background often gives more dependable contrast than a shadow alone.

Keep one short idea on screen at a time.
Use sentence case instead of long passages in all capitals.
Leave the text visible long enough to read without pausing.
Keep captions separate from prices, dates and calls to action.
Check the final export on a phone, not only on a desktop editing monitor.

4. Describe essential visual information

If a visual carries information that the narration never explains, add that information to the spoken track, provide audio description, or create a descriptive text alternative. WCAG addresses prerecorded visual information through audio description or a media alternative, depending on the conformance level and format.^[5]

A restaurant video does not need narration for every close-up. But if the only evidence of an allergen notice, event date or accessibility feature appears silently on screen, that detail should also be communicated another way. The same principle applies to before-and-after results and charts.

5. Record clean, understandable audio

Captions do not replace clear sound. Choose a quiet position, monitor the microphone with headphones and record a short test before the full answer. Keep music below speech and avoid placing the speaker directly beside refrigerators, ventilation or a busy street when a quieter setup is available.

If several people speak, ask them to introduce themselves or identify them in the captions. A visible, well-lit face can also help some viewers understand speech; W3C recommends considering speaker visibility when feasible.^[4]

6. Avoid unsafe flashing

Fast edits are not automatically inaccessible, but flashing can create a serious barrier. WCAG 2.2 says web content should not flash more than three times in any one-second period unless it remains below defined thresholds.^[6] Review strobe effects, rapid white frames, animated graphics and footage containing strong repeated flashes.

When the effect is not essential, remove it. When the subject itself contains flashing light, choose safer footage and avoid using the most intense sequence as the opening.

7. Give the post useful surrounding text

The caption around a social post can carry context that does not fit inside the video. Name the service, explain the result, repeat the deadline and include a clear next step. On a website or long-form platform, a transcript can also make spoken information easier to scan and reference. W3C notes that captions and transcripts share much of the same text, so one can help produce the other.^[2]

A compact pre-publish review

Watch the video once with sound off.
Listen without looking at the screen.
Proof every caption against the final audio.
Check important text on a phone at normal viewing distance.
Confirm captions do not cover essential visuals.
Remove unnecessary flashing or rapid full-screen brightness changes.
Repeat the offer, deadline and next step in the post text.
Ask someone who did not edit the video to review it.

Accessibility is not a claim that one checklist can guarantee. It is a production practice: identify the information, provide more than one way to receive it, test the actual export and correct the barriers you find.
