Suggested exercise, not a reported test: Make a fictional three-scene employee induction, then change one policy sentence in both language versions.
Visit HeyGen ↗Check pronunciation, caption agreement and whether the reviewer can identify the exact scene and language that changed.
Count revision rounds per approved language and the people who need access, alongside generated video time.
Keep the approved script, language versions and permission records together so a future update does not reuse withdrawn material.
