The preflight bench

One focused pass before release

Caption generators solve the words. This check helps protect the image those words sit on.

  1. 01

    Pair the final exports

    Drop in the video and its SRT or WebVTT file. Files stay in local memory.

  2. 02

    Sample every cue

    The checker seeks into each timed cue and looks for face or dense visual overlap.

  3. 03

    Make the call

    Review exact timecodes, compare a safer position, mark protected regions, and export the list.

Visible, explainable alerts

A warning you can inspect—not a magic score.

The review shows which region triggered an alert, the cue’s exact time, and a suggested alternate zone. Add your own protected area for an interpreter or sign the automated pass may miss.

  • Face detection when the system supports it
  • Script-agnostic visual density heuristic
  • Free CSV export for an editor or client

Detection is advisory. Always watch the final export with captions enabled, include people who use captions in your review when possible, and check your publishing platform’s own caption rendering.
