How to Add Captions to a Video (Auto Captions, 2026)
By the Maybe Lab teamThe fastest way to add captions to a video is auto-captioning: a tool transcribes the audio, you fix any errors, and it burns the text onto the video. Since most social and feed video is watched on mute, captions aren't a nice-to-have — they're what makes the message land at all. Here's how to do it, and how to skip the step entirely.
Captions vs. subtitles vs. burned-in
| Type | What it is | Best for |
|---|---|---|
| Auto captions | Machine transcription of speech | A fast first draft to correct |
| Burned-in (open) | Text baked into the video pixels | Social, ads, feeds — always visible |
| Closed captions (.srt) | A toggleable subtitle file | YouTube, accessibility, SEO |
| Subtitles | Translated text for other languages | International reach |
How to add captions, step by step
- Auto-transcribe the audio with a captioning tool.
- Proofread — fix product names, jargon, and numbers the AI misheard.
- Time them to the speech so lines appear as they're said.
- Style for legibility — bold, high-contrast, inside the safe zone.
- Export burned-in for social, plus an .srt file for YouTube.
Caption styles that actually read
Legibility beats decoration. Use a heavy weight, a solid or semi-opaque background behind the text, and keep lines short — two to three words for punchy social captions, a full line for explainers. Keep them within the vertical safe zone so platform buttons don't cover them, and match your brand type so they don't look bolted on.
Or skip the step entirely
Captioning is a chore because it comes after the edit. When a video is generated from a brief, the on-screen text is part of the design from the start — accurate, on-brand, and correctly placed with no transcription pass. Describe your video to Maybe Lab and it produces captioned motion graphics directly, the same way an AI video maker handles the rest of the production.
Adding captions FAQ
How do I add captions to a video?
Auto-transcribe the audio, proofread the text, time it to the speech, style it for legibility, and export it burned-in for social plus an .srt file for platforms like YouTube.
Do captions help video SEO?
Yes. A caption or subtitle file gives search engines and platforms text to index, which can improve discoverability, and it makes your video accessible to more viewers.
Should captions be burned-in or a separate file?
Burn them in for social feeds and ads where they must always show; use a separate .srt file on YouTube and for accessibility so viewers can toggle them.
Can I make a video that's already captioned?
Yes. A generator like Maybe Lab builds the on-screen text into the design, so the video comes out captioned and on-brand with no separate transcription step.
Captions are the difference between a muted video that works and one that gets scrolled past. Describe your video, and Maybe Lab makes it captioned from the first frame.
