Free subtitle generator (SRT and VTT)
How to use it
- Choose an MP4, MOV, MP3, M4A or WAV file, up to 3 minutes and 25 MB.
- Pick 2 to 3 words per cue for vertical video, or full sentences.
- Download SRT or VTT and import it into your editor or upload it with your video.
Short cues or full sentences?
Vertical videos are watched on a small screen, often fast. Short cues of two or three words are easier to read at a glance and leave more of the frame visible. Full sentences suit longer explainers, horizontal video and accessibility files.
SRT vs VTT
Both formats are plain text files with timed lines. SRT is the most widely supported by video editors. VTT is the web standard and is commonly used by web players. If you are not sure, start with SRT.
Questions
Will the subtitles be burned into my video?
No. These are separate files. ViralAri's editor can burn in styled, word-by-word captions when you export a checked draft.
Is my file stored?
No. It is sent to the speech model for this request only.
