# Accessible Product Demo Videos: Captions, Subtitle Files and Timed Scripts

Ship accessible product demo videos with on-screen captions, subtitle files and timed scripts for viewers on mute and people using assistive tech.

## Key takeaways

- Ship captions and an SRT/VTT with every external demo by default.
- Keep product names consistent across voice, captions and script.
- Avoid conveying meaning with colour or motion alone.
- Provide a text how-to twin for critical workflows.
- Recheck after rebuilds so accessibility artifacts stay in sync with the new audio.

Accessible product demo videos include on-screen captions, downloadable subtitle files, and a timed script that matches the voiceover. That helps people watching without sound and people using assistive technologies. Accessibility is part of shipping the demo, not a later patch.

## What DemoVexa already frames as default

DemoVexa's [why DemoVexa](https://demovexa.com/why-demovexa) accessibility line lists captions on screen, subtitle files and a script with timings for people who watch without sound or use a screen reader.

## Checklist before you publish

1. Captions readable on mobile (size, contrast).
2. SRT/VTT uploaded wherever the video is hosted.
3. Script available as text on the companion page.
4. No essential information only in non-text UI flashes.
5. Voiceover pace that captions can follow.

## Building accessibly in DemoVexa

Write and approve the Script first ([script docs](https://demovexa.com/docs/videos/script)). Generate voice ([voice docs](https://demovexa.com/docs/videos/voice)). Export formats and subtitle downloads ([render docs](https://demovexa.com/docs/videos/render)). Host text steps on docs or blog so screen-reader users are not forced through a player to learn the clicks.

## FAQ

### Are auto-captions enough?

No for product names. Review and upload a corrected file.

### Do burned-in captions hurt localization?

They can. Prefer separate subtitle tracks when you ship many languages; use burned-in for social muted feeds when needed.

### What about audio descriptions?

For complex visuals beyond UI chrome, consider an extended description on the page. Most SaaS how-tos are covered by a clear voiceover plus text steps.

### Who accepts the checklist?

Treat it like QA on the Export step before Publish.

### Does accessibility help SEO?

Transcripts and clear text twins help humans and machines. See [SRT and VTT subtitles](https://demovexa.com/blog/srt-vtt-subtitles-youtube-seo) and [getting cited by AI assistants](https://demovexa.com/blog/get-cited-by-ai-assistants).

### Is this legal advice?

No. It is product practice. Follow the laws and standards that apply to your markets.
