Seed captions from the script

Start from the written script, narration plan, or lyric timing and create caption cues that stay connected to the video timeline.

  • Caption cues seeded from scene text and narration.
  • Timeline placement against generated and source clips.
  • Cue editing for wording, duration, and line breaks.

Import, audit, and resync subtitles

Bring in existing SRT, VTT, LRC, ASS, SBV, or TTML files, then check readability and timing before the final render.

  • Subtitle import for common caption formats.
  • Quality audit for long lines and dense cues.
  • Linear resync tools for captions that drift.

Export captioned video cuts

Burn captions into the final video or export sidecar subtitle files for YouTube, social platforms, and review workflows.

  • Burned-in or sidecar captions.
  • SRT, VTT, ASS, LRC, SBV, TTML, and transcript exports.
  • Synced captioned output from the same project state.
