VideoVault

Listen to Lecture Videos in the Background

If your lecture is already a video file on your iPhone — from Files, an export, or Photos — VideoVault can play it while you take notes in another app or lock the screen. Import the lecture, enable Background Playback (Lifetime Pro), and treat the soundtrack like a study podcast. VideoVault does not fetch lectures from online course sites or generate transcripts.

Real-world scenarios

Review a recorded seminar while commuting

Import last week’s seminar recording, start playback, lock the phone, and scrub ±15 seconds when you need to rehear a definition.

Take notes in a separate app

Play the lecture in VideoVault, switch to Notes or a PDF reader, and keep the audio running with background playback enabled.

Queue a week of class clips

Build a playlist of lecture segments in order so one session flows into the next without reopening Library each time.

Step-by-step

  1. Gather lecture files offline

    Save or copy lecture videos you are allowed to keep into Files, iCloud Drive, or Photos, then import them into VideoVault.

  2. Organize by course with playlists

    Create a playlist per class or week and add the imported clips in syllabus order.

  3. Turn on Background Playback

    With Lifetime Pro, enable Background Playback in Settings before you start a long study block.

  4. Use speed and skip controls

    In Player, adjust speed for dense sections and use ±15 second jumps to revisit examples without scrubbing blindly.

How VideoVault helps

  • Local library means lectures remain available offline after import.
  • Playlists mirror course structure better than a flat camera roll.
  • Background playback supports note-taking and commuting workflows.
  • Optional Extract Audio (M4A) creates lighter study audio from video lectures you own.

FAQ

Can VideoVault open my school’s streaming portal?

No. It plays local files you import. Download or export lectures only when your school’s rules allow it, then import the file.

Will it transcribe the lecture for me?

No. VideoVault does not offer AI transcription or captions. Use Player controls and notes instead.

How do I keep lectures if I delete the app?

Export a Full Library Backup to Files or iCloud Drive first. Restore Purchase alone will not bring media back.

Can I listen at 1.5x or 2x?

Yes. The in-app player includes playback speed options suitable for review sessions.
