New caption tracks
Create Subtitles from Audio or Video
Use this cluster when the media has no subtitle track. Upload a file you own or are allowed to process, convert its speech into timed cues, review the result, and export for the intended player or editor.

Audio-only recordings need the same speech-to-caption timing as video, but video workflows often return to an editor or publishing platform. SRT is the broad compatibility choice; VTT is the web-native choice.

Create Subtitle Files from Audio
Audio-to-subtitle work starts without a picture, so language selection, names, speaker context, and the future video edit matter. This cluster explains how to build timed SRT or WebVTT from recordings and validate it against the eventual destination.

A video caption workflow must match the final cut and the publishing environment. These guides separate generation from rendering, show when a sidecar file is preferable, and provide checks for timing, speakers, sounds, and safe-area presentation.

Questions about this subtitle workflow
Can a subtitle generator work without an existing caption track?
Yes. It analyzes speech in an audio or video file and creates new timed cues.
Does creating a subtitle file burn text into the video?
No. The result is a separate sidecar file. Import it into an editor if you need open captions permanently rendered into the image.
Should I create SRT or VTT?
Choose SRT for broad editor and player support. Choose VTT for HTML5 video and browser-based players.
