How to add subtitles to a video
- Drop your video (MP4, MOV or WebM) in the box, or try the sample.
- Choose the language spoken in the video, or let it be detected. To get English subtitles for a video in another language, choose Translate to English.
- Press Make subtitles. The AI downloads once (about 40 to 75 MB) and then works on your device.
- Play the video to check the captions. Click any line to fix a word or change its timing.
- Download the .srt or .vtt file, or press Make video with subtitles.
Subtitles that are easy to read
The AI gives a time for every word, so the captions are cut where people pause and at the ends of sentences, with short lines that are easy to read on a phone and appear exactly when the words are spoken. Choose Short lines for the punchy, few-words-at-a-time captions popular on TikTok and Reels.
SRT file or burned-in captions?
- SRT or VTT file: upload it with your video to YouTube, Facebook, LinkedIn or Vimeo, or load it in VLC. Viewers can turn the subtitles on and off, and search engines can read them.
- Video with subtitles: the captions become part of the picture, in the style you chose, so they show everywhere, including Instagram, TikTok, WhatsApp and on muted autoplay, where most people watch without sound.
Making the video plays it through once in the background, so a 2-minute video takes about 2 minutes.
