Frequently asked questions
What's the difference between translating VTT and SRT?
Both carry timed text, but WebVTT (.vtt) is the web-native format — it supports browser track captions and cue settings like position and styling, while SRT is the universal editor and player format. SubtitleFlow reads and exports both; translating a VTT keeps it as a valid .vtt.
Will my WebVTT cue settings and styling survive translation?
Yes. SubtitleFlow rewrites only the spoken text inside each cue and regenerates the file cleanly, so cue timing and structure stay valid for HTML5 video and web players.
Which languages can I translate WebVTT into?
100+ languages with context-aware AI, including Spanish, Chinese, Japanese, Korean, French, German, Portuguese, and Arabic, with the timing preserved.
How do I translate a WebVTT (.vtt) caption file?
Upload your .vtt file to SubtitleFlow, pick a target language, and the context-aware AI translates each cue into 100+ languages. It exports a valid WebVTT file with cue timing and structure preserved, ready for HTML5 video, web players, and learning platforms.
