# Video Subtitles

### Subtitles render spoken audio as on-screen text so the content still works for sound-off viewers and for audiences in other languages.

## Why do they matter so much in commerce?

A large share of mobile viewers watch with the sound off. Without subtitles the product explanation simply doesn't land — and in short-form, where the first few seconds decide whether someone stays, that loss is expensive.

## What styling actually reads well?

Strong contrast against the background, placement inside the lower safe area, and no more than two lines at a time. The bottom of the frame collides with UI buttons easily, so check it on a real device.

## Frequently Asked Questions

**Q. How accurate is auto-captioning?**

Good on ordinary speech, unreliable on brand names, product names, and jargon. Reviewing just those terms before publishing is the efficient approach.

**Q. Do subtitles help SEO?**

When the subtitle text is exposed on the page, search engines and AI can read the video's content as text, which makes it far easier to interpret than video alone.
