SRT Captions Overview
SRT (SubRip Subtitle) files contain timestamps that sync captions to your audio. VocalLab generates SRT files automatically alongside your audio — as short phrases or word by word.
What SRT enables
- Karaoke-style captions — words highlight as they're spoken
- Auto-captions on YouTube and TikTok that are perfectly timed
- Accessibility — captions for deaf/hard-of-hearing viewers
- SEO — YouTube indexes caption text for search
How VocalLab's SRT works
When you generate audio, VocalLab also calculates the exact timestamp for every word. The SRT file maps each caption — a phrase, or a single word in word-by-word mode — to its precise start and end time in the audio.
SRT vs. other subtitle formats
| Format | Use case |
|---|---|
| SRT | Universal — works on YouTube, TikTok, most video editors |
| VTT | Web video players (HTML5) |
| ASS/SSA | Advanced styling (karaoke effects in video editors) |
VocalLab exports SRT — the most widely supported format.
