A small part of a considered workflow
Supports up to 500 plain-text cues and files under 1 MB. Styling, positioning, karaoke tags and VTT metadata are not supported. Cue IDs and NOTE comments are omitted. This editor does not transcribe speech or fetch captions from YouTube.
Read captions against the final audio, including speaker changes and meaningful sounds. Timing checks cannot establish transcription accuracy or accessibility quality. Review on the destination player before publishing.
Your files and your draft
Text drafts save in this browser when storage is available. Local video files are played on this device and are not stored in your draft or uploaded. A JSON project backup restores the editable rows; the publishing export contains only the chapter list, shot list or captions. Keep a backup before clearing browser data.
