What is the difference between SRT and VTT?

Both store captions with timings. SRT is the most widely supported format; VTT is the web standard used by HTML5 players. YouTube accepts both.

Can I change the line length?

Yes. Choose the maximum characters per line and lines per caption, and the preview updates before you download.

Which languages are supported?

More than 90, detected automatically. The subtitles are in the language spoken in the video.

How much does it cost?

Your first 2 videos are free (up to 20 minutes each) after confirming your email. Then credit packs start at $5 for 5 videos. Each credit includes subtitles, the transcript and chapters.
