Media Preflight Kit

A step-by-step workflow for checking media metadata and preparing quick deliverables. 100% client-side.

Workflow

  1. 1) Verify duration

    Use Media Duration Analyzer to confirm length. This avoids “it’s 29.97s not 30s” surprises when exporting or placing in timelines.

  2. 2) Check bitrate/codecs

    Use Media Bitrate Checker to see stream details. This is useful for diagnosing “why is this file huge?” or “why is audio quiet?”

  3. 3) Extract audio (optional)

    If you only need the audio, use Video → Audio Extractor. Choose MP3 for smaller files, WAV for lossless.

  4. 4) Trim a clean segment (optional)

    Need a teaser clip or remove dead air? Use Audio Trim.

  5. 5) Make a shareable MP4 (optional)

    For quick previews (Slack, clients, etc.), use Image + Audio → Video to wrap an audio track in a still-image MP4.

Common pitfalls

  • Very large files can run out of memory in the browser.
  • DRM-protected videos often cannot be processed (and should not be).
  • Some formats may trim inaccurately when using stream copy.
