How are subtitles created?

First, the speech is transcribed with timestamps. Then the text is split into subtitle lines in your browser: a new cue starts at pauses and sentence ends, each line stays within the length you choose, and each subtitle stays on screen long enough to read without overlapping the next one.

Which format should I choose?

Format	Where it's used
SRT	YouTube, video editors (Premiere, DaVinci Resolve, CapCut), social media, desktop players
VTT (WebVTT)	Video players on websites, the HTML5 `<track>` element, e-learning platforms

Line length guide

Landscape video: 37–42 characters, 2 lines.
Vertical video (Reels, Shorts, TikTok): 20–28 characters, 1 line.
Presentations and lectures: 42 characters, 2 lines; keep it at 2 lines for fast speakers.

To convert a subtitle file to another format (for example VTT to SRT) or shift its timing, use the studio. There you can also translate subtitles and create multilingual versions.
