Treat preflight as a release gate

This audit decides whether a video can publish, needs revision, or must stop for a safety, evidence, or access failure. Bring the objective, storyboard, final cut, captions, transcript, text alternative, practice task, source record, version, and correction owner. Do not average hard failures into a favorable score.

W3C’s media accessibility guidance and How People Learn II provide important access and learning context, but neither certifies a local video. Record evidence and owner beside every item. Approval expires when the task, media, source, learner context, or platform changes.

Checks 1–4: purpose and scene logic

Check 1 states an observable learner outcome. Check 2 explains why moving media is necessary. Check 3 assigns every scene a learner question and evidence role. Check 4 makes consequential cues and reasons visible before action. Remove scenes that serve only prestige or production effort.

Ask whether a static or searchable format would better serve any segment. If so, separate it. Keep visual and narration jobs complementary rather than duplicating dense text. CMU’s active-learning guidance supports worked examples and learner decisions, not feature tours.

1. Outcome is observable.

2. Video has a medium-specific advantage.

3. Every scene serves a question.

4. Cue and reason precede action.

Checks 5–8: pacing and learner action

Check 5 segments content around meaningful subgoals. Check 6 gives control through pause, replay, speed, and chapters where supported. Check 7 places prediction or practice before key reveals. Check 8 provides feedback plus a changed-context task and outcome check.

Do not treat duration or completion as comprehension. A short compressed lesson may fail pacing; a longer structured one may be usable. Record prompts and assistance on the practice task. CAST’s guidelines support learner control and varied engagement while preserving the objective.

5. Chapters match instructional subgoals.

6. Learner can control pacing.

7. Attempt occurs before reveal.

8. Feedback and transfer check exist.

Checks 9–12: media accessibility

Check 9 verifies accurate synchronized captions and meaningful sounds. Check 10 supplies a structured current transcript. Check 11 describes essential visual information through narration, text, or audio description. Check 12 verifies contrast, legibility, keyboard, focus, and accessible player behavior. Meaning cannot depend on color, cursor, location, or sound alone.

Test the delivered player with alternatives, not just source files. Auto-generated captions require review. If integrated narration already describes an essential visual, document that decision. Keep every access asset synchronized with the same release.

9. Captions pass content and timing review.

10. Transcript matches the final cut.

11. Essential visuals have an equivalent.

12. Player and displayed text are operable.

Checks 13–16: evidence and maintenance

Check 13 verifies claims, sources, permissions, privacy, and safe sample data. Check 14 records platform or process version and asset dependencies. Check 15 creates change triggers and a dated review. Check 16 provides a correction path and learner notification for material errors. A polished obsolete video is an instructional failure.

Run a dependency scenario: change one interface label or source conclusion and identify affected scenes, captions, transcript, practice, and text alternative. If the team cannot find them, improve modularity and traceability before release. Assign a single maintenance owner with backup.

13. Claims, rights, privacy, and sample data verified.

14. Versions and dependencies traceable.

15. Review and event triggers scheduled.

16. Correction and notification owned.

Resolve failures through dependent checks

For each failure, record repair, evidence, owner, and due date. Re-run downstream checks: a new scene needs access review; a changed objective invalidates practice and verification; a new platform reopens player tests. Archive prior approval. Set full review by 2027-02-10.

Passing sixteen checks means one release is coherent and accessible enough for bounded use. It does not guarantee learning, transfer, reach, or revenue. Observe first divergence with consent and appropriate privacy, preserve unsuccessful cases, and revise without making claims beyond the evidence.
