A video can carry essential information through speech, sound and visuals. Production planning should identify each channel and preserve its meaning for people who cannot rely on that channel.
What you will leave with: Leave with an accessibility deliverables list tied to the script, final edit and publishing player.
Use this when
- A video depends on on-screen instructions or unspoken demonstrations.
- Automatic captions are being published without review.
- A production quote excludes transcripts and accessible versions.
This is not a complete legal compliance assessment or a claim that captions alone make every video accessible.
Mark where the information lives
Review the script or storyboard and mark meaning carried by speech, essential sounds, on-screen text and visual action. A presenter saying as you can see may leave the central instruction entirely visual. A sound effect may communicate an alert that is otherwise absent. Identify these dependencies before recording.
Decide which information can be integrated naturally into the narration and which needs a separate alternative. Ask whether the demonstration still makes sense without seeing the screen and whether the message remains understandable without hearing the soundtrack. These are diagnostic questions, not a substitute for testing with the relevant audiences.
Specify the appropriate alternatives
W3C's media guidance recommends planning accessibility from the beginning and addressing descriptions of necessary visual information alongside captions, transcripts and the media experience. The exact requirements depend on the content and format; a transcript and captions are not interchangeable in every situation.
Write the required files and review responsibilities into the production brief. Include language versions, synchronization, important speaker identification and any necessary visual description. Ask the publisher what the chosen player supports before promising a format. A deliverable that cannot be used on the actual destination is unfinished work.
Review the final edit, not an old script
Use the final audio and picture to check alternatives. Scripts change, words are improvised and graphics are updated during editing. Automatic transcription can provide a starting point, but a responsible reviewer must check names, technical terms and statements where a small error changes the meaning.
Inspect timing and readability in the actual viewing context. Confirm that captions do not obscure essential demonstrations or labels. For descriptions, preserve the information needed to understand the action without inventing details that are not present. Keep the accessible version aligned with the same factual and legal checks as the main film.
Publish and maintain the complete package
Test playback controls and access to the alternatives after upload. A correct caption file may be missing, disabled or associated with the wrong language. A transcript link may point to an earlier cut. Treat these as release failures rather than assuming the exported files prove successful delivery.
Store version relationships so that later edits trigger review of every dependent asset. If a product warning changes, update the video, captions, transcript and descriptive material together as applicable. Record any unresolved limitation openly and assign it. Do not report a video as fully accessible on the strength of one checked component.
Make the reasoning concrete.
A hypothetical appliance brand makes a tutorial showing how to attach a removable water tank.
Integrated explanation
Opening: The presenter names the alignment mark and describes the locking action while demonstrating.
Hypothesis: Essential visual information becomes available through the explanation.
Risk: The wording must match the actual action and not omit a safety step.
Reviewed alternatives
Opening: The final captions and transcript are checked against the released edit.
Hypothesis: People receive consistent instructions across formats.
Risk: A transcript copied from an earlier script may preserve an outdated sequence.
The producer assigns review owners before filming and checks the whole published package after upload.
Take the questions into your next brief.
Use these prompts in your own notes. Nothing is submitted from this page.
Information
Which meaning is carried only by sound or visuals?
Deliverables
Which alternatives does this format require?
Ownership
Who creates and checks each version?
Destination
Can the publishing player expose the alternatives correctly?
Changes
What later edit should trigger a complete version review?
Watch for the wrong conclusion.
- Treating automatic captions as a finished deliverable.
- Checking alternatives against a script rather than the final cut.
- Assuming captions communicate essential unspoken visuals.
- Uploading files without checking their availability in the player.
Your next action
Mark one storyboard for audio-only and visual-only meaning, then add the necessary alternatives and reviewers to its production plan.
