Add accurate, high-contrast captions that match the speech, keep lines short and stay inside the safe area. They help people watching without sound and improve accessibility.
Many people watch short videos with the sound off. Captions keep them with you, and they help viewers who are deaf or hard of hearing.
Style
- Font: a bold, simple sans-serif.
- Contrast: white text with a thin outline or a soft box behind it.
- Size: large enough to read on a small phone.
- Highlight: color the key word or the word being spoken, but sparingly.
Timing
- Show each line as it is spoken, or a beat before.
- Keep lines to about two short rows.
- Avoid flashing text that changes faster than people can read.
Placement
Keep captions inside the safe area so the app interface doesn't cover them. Read vertical video safe zones.
Accuracy
- Fix names, brands and numbers by hand.
- Don't rely only on automatic captions. Always proofread.
- Match the spoken language, or provide translated captions as a separate version.
Closed vs open captions
- Open (burned in): part of the picture, always visible. Common for social.
- Closed (a separate file, like SRT): viewers can switch them on or off. Better for YouTube and websites, and good for accessibility and search.
Provide a transcript
For videos on your site, add a transcript or summary beneath the video. It helps readers and search engines. See video SEO for business websites.
