Your Training Videos Aren't Accessible: A Practical WCAG and Section 508 Checklist

A training video can have accurate narration, attractive visuals, and closed captions—and still exclude learners. The captions may omit meaningful sounds. A diagram may never be explained aloud. Text may be too small. Color may carry the only distinction. The player may be impossible to operate by keyboard. A quiz may trap focus. The transcript may be an inaccessible PDF. The localized version may lose every accessibility asset created for English.

Accessibility must be designed across the whole delivery chain: source, script, visuals, audio, alternatives, player, page, interaction, and review. A generator supplies one part of that chain. Following a checklist improves the work, but it does not by itself establish WCAG conformance, Section 508 conformance, or legal compliance.

This guide summarizes practical production questions using current W3C Web Accessibility Initiative media guidance and Section508.gov synchronized-media guidance. Apply the standards and policies that govern your organization and seek qualified review.

First identify the media type

• Audio-only: a podcast or narration without video. Section508.gov guidance calls for an accessible transcript that conveys equivalent information.
• Video-only: silent animation or visual demonstration. Provide an equivalent text description or audio track according to applicable requirements.
• Synchronized media: audio and video work together. This is the normal training-video case and raises caption and visual-description requirements.

Do not copy requirements from one media type to another without analysis.

1. Write the script so listening carries the lesson

The least expensive time to solve visual-description problems is before production. W3C guidance notes that integrated description—having the main narration naturally describe important visual information—works well for many training videos.

Instead of saying “As you can see, move through these three stages,” write: “First verify the request, then obtain manager approval, and finally record the decision in the case file.” Instead of showing a red warning without narration, say what the warning means and what action follows.

• Narrate essential diagrams, charts, screen changes, labels, and actions.
• Avoid directional language that assumes sight unless the location itself matters.
• Give learners enough time to hear, read, and process information.
• Expand unexplained acronyms and define unfamiliar terms.
• Keep one learning objective per short module where practical.

2. Caption speech and meaningful sound

WCAG guidance defines captions as synchronized text alternatives for speech and non-speech audio needed to understand the content. That means dialogue, speaker identity when unclear, meaningful music, alarms, laughter, tone, and sound effects—not merely an unedited speech transcript.

The current Section508.gov caption guidance emphasizes synchronization, spelling, grammar, punctuation, important sounds, and adequate reading time.

• Human-review automatically generated captions.
• Correct names, jargon, acronyms, numbers, and punctuation.
• Identify speakers when the image alone carries that information.
• Describe meaningful non-speech audio.
• Keep captions synchronized and visible long enough to read.
• Position or style captions so they do not obscure required visual information.

3. Provide an accessible transcript

A transcript helps people who are DeafBlind, people using assistive technology, learners who need more time, people in low-bandwidth environments, and anyone searching for a specific step. A descriptive transcript can combine spoken content, meaningful sounds, and descriptions of important visuals.

Publish it as accessible HTML or another tested accessible format. Give it a clear heading, logical order, speaker identification, language metadata, and links that make sense out of context. A raw text dump buried behind an unlabeled download is not a complete transcript experience.

4. Handle important visual information

If the main audio already communicates every important visual fact, separate audio description may not be needed for that information. If the video teaches through unspoken diagrams, actions, on-screen text, scene changes, or demonstrations, provide an equivalent method appropriate to the requirement and context.

Options include integrated description in the main narration, a separate described version, a secondary audio track, or a descriptive transcript. W3C distinguishes these approaches and notes that the media player must support a separate track when that method is used.

5. Design readable visuals

• Use sufficient contrast for text, icons, controls, diagrams, and meaningful states.
• Do not use color as the only way to distinguish correct/incorrect, current/expired, or step A/step B.
• Keep on-screen text large, concise, and present long enough to read.
• Avoid placing required text inside visually busy backgrounds.
• Use consistent layout and signaling so learners can predict where information appears.
• Avoid unnecessary flashing, rapid cuts, parallax, and motion; evaluate applicable thresholds and provide controls where required.
• Do not assume a brand color or AI-generated visual is accessible without testing the actual frame.

6. Choose and test the player

The MP4 is not the complete user interface. The player must make controls discoverable, labeled, operable, and compatible with assistive technology. Test play/pause, seek, volume, captions, audio description, playback speed, full screen, focus order, visible focus, and exit behavior with a keyboard.

Section508.gov notes specific requirements for caption and audio-description controls in applicable ICT and provides an example where those controls appear at the same menu level as other program controls. Organizational and legal requirements vary, so test the actual destination: LMS, help center, portal, intranet, or embedded third-party player.

7. Make surrounding content and interaction accessible

A compliant player cannot repair an inaccessible course page. Check heading structure, language, link names, iframe title, focus order, error messages, timing, forms, quizzes, branching choices, completion controls, downloadable files, and responsive zoom. If the LMS wraps the video in SCORM, test the package with keyboard and assistive technology—not only the video file.

8. Preserve accessibility across languages

Every localized video needs reviewed captions, transcript, visual description, player language, control labels, and accessible surrounding content in the appropriate language. Do not reuse English caption timing blindly when translated narration changes pace. Maintain locale parity alongside source-version parity in the multilingual video pipeline.

Where Golpo ends and the publishing workflow begins

Layer	Responsibility
Golpo generation	Create narrated media from approved prompts, scripts, documents, and supported user media using selected visual and voice instructions.
Content team	Approve source, write accessible narration, review visuals, facts, pacing, language, and alternatives.
Caption/transcript workflow	Create, correct, synchronize, localize, format, and publish accessible text alternatives. Verify current capability per Golpo interface rather than assuming.
Player/LMS/website	Provide operable controls, caption and description support, focus behavior, semantics, interaction, and accessible surrounding content.
Accessibility review	Test applicable requirements and usability with trained reviewers and disabled users where practical.

Using Golpo does not make an output WCAG- or Section 508-conformant automatically. Conversely, an accessibility gap in the publishing player is not evidence about the generated narration. Review the complete system and assign owners to every layer.

Release checklist

• Approved source and learning objective.
• Essential visuals conveyed in audio or an appropriate alternative.
• Reviewed captions with meaningful sounds and speaker identification.
• Accessible transcript or descriptive transcript as required.
• Contrast, text size, timing, motion, and color-use checks.
• Keyboard-operable, labeled player controls with visible focus.
• Accessible page, quiz, downloads, and LMS wrapper.
• Localized accessibility assets for every released language.
• Automated technical checks plus manual review.
• Testing evidence, owner, exceptions, remediation plan, and review date.

FAQ

Do captions make a video accessible?

They are essential, but accessibility also includes visual information, alternatives, readable design, motion, the player, the page, interaction, localization, and testing.

What is the difference between captions and subtitles?

Accessibility captions include speech and meaningful non-speech audio. Dialogue-only subtitles may omit speaker identity, music, alarms, tone, and sound effects needed to understand the media.

When is audio description needed?

When important visual information is not conveyed in the main audio, provide an equivalent approach appropriate to the applicable requirement and delivery context.

Does Golpo make a video compliant?

No tool automatically proves conformance. The complete content, media alternatives, player, page, configuration, and testing determine the result.

Who should test?

Use trained reviewers and include people with relevant disabilities where practical. Automated testing alone cannot establish an equivalent and usable learning experience.
