Product Demo Caption Review Checklist
Review a demo’s captions against its real audio, timing, speaker changes and meaningful sounds before publishing the final player experience.
When to use this template
Use this after creating a caption draft for a product recording, including captions initially produced by an automated tool.
Choose another approach when: You want to publish unchecked auto-captions, treat translated subtitles as a complete accessibility review, or assume a transcript file proves captions work in the actual player.
Gather these inputs
- The final video cut and its actual audio.
- An editable caption draft with timing.
- The intended publishing player and appropriate review access.

Worked example
Illustrative example, not a Crany customer result. Replace every example detail with facts you can verify.
In a fictional app demo, automatic captions turn “not available in beta” into “now available in beta.” The reviewer corrects the negation against the audio before publication. They also fix the product name and check that captions do not cover the button being demonstrated. The final check uses the published player with captions enabled. An accurate source file alone would not reveal that the wrong language track was uploaded. No claim is made that captioning by itself covers every visual-access need in the demo.
How to use it
- Review the caption text against the final audio rather than an earlier script.
- Correct meaningful errors and inspect timing, speaker context and placement in playback.
- Verify the correct track in the actual published player after upload.
Check before using it
- Automatic output is reviewed rather than accepted as accurate by default.
- Necessary non-speech information is considered along with speech.
- The checked caption file corresponds to the final video cut.
What to measure
Track corrected meaning-changing errors and verified player access. Captions make necessary audio available to more viewers; a passing caption review is not a full media-accessibility conformance assessment.
