Built to be updated
Policies change on their own schedule, and a training video that contradicts the current policy is worse than none. Build short modules around single procedures, tie each to the policy or document version it teaches, and log which version is live in the learning management system. When the policy changes, regenerate the affected module, keep the rest, and retire the old file rather than leaving it in a shared folder where someone will find it. Package modules to the standard your LMS uses, such as SCORM 1.2, SCORM 2004, xAPI or cmi5, so completion records show who saw which version.
A multilingual workforce
Translate for the workforce you have, not only the markets you sell to: a Dutch warehouse may need Polish and Romanian as much as Dutch. Localise voice, captions and on-screen text, and pick the right variant, such as Brazilian or European Portuguese, Latin American or European Spanish. Some countries set rules: in France, Article L1321-6 of the Labour Code requires documents containing obligations for employees, or information they need to do their work, to be in French. Keep a terminology list per language for equipment, roles and safety terms, so every module calls the same thing by the same name.
Captions and accessibility
Training is often mandatory, so everyone required to take it must be able to. WCAG 2.1 and 2.2 at level AA, the usual benchmark, expect captions for prerecorded video (success criterion 1.2.2) and audio description where important information is only visual (1.2.5). Writing narration that describes what matters on screen removes most of the need for separate audio description. Use sidecar caption files so learners can switch language, keep diagrams high in contrast, and never rely on colour alone to show which option is correct. In Europe, EN 301 549 carries the same criteria into public procurement.
Experts as reviewers, not afterthoughts
A generated scene can look right and be wrong: gloves missing in a chemical-handling scene, a forklift loaded unsafely, a step skipped in a clinical procedure. Subject-matter experts should review visuals as well as scripts, because learners copy what they see. Give them a structured sign-off: accuracy of every step, equipment and safety gear shown, regulatory wording, then approval for release. In Synthetic White, approvals and workflows assign those roles and record each sign-off in an audit trail, and saved presenters, sets and equipment keep modules consistent, so an update does not introduce a new-looking warehouse halfway through a course.
