Import Video & Subtitles

Prism Lines uses local video + subtitles as raw material. Import TV series, films, interviews, or any subtitled video.

Supported Video

Add files to the in-app library or use Import to pick a local path. Common formats include MP4, MKV, MOV (see your build’s release notes).

TIP

For a first run, choose a moderately sized episode with clear subtitles to experience the full workflow quickly.

Subtitle Sources

TypeNotes
EmbeddedSubtitle tracks inside the video file; pick a language track at playback
External.srt, .ass, etc. alongside the video or via a path you specify
MultilingualKeep multiple tracks; switch or compare while learning (if supported in your version)

If timing is slightly off, adjust offset in Settings.

How Material Is Split

After import, the app:

  1. Parses the subtitle timeline;
  2. Maps each cue to a learning unit (sentence + start/end time);
  3. Links video segments for playback during study.

No manual cutting—Prism Lines splits by subtitles automatically. Next: Learning Session.

Compliance

  • Use video and subtitles you have the right to use.
  • Prism Lines does not provide or distribute any media; it only processes files on your computer.
