Everything about every stream

Drop in a file and get an instant, beautifully organized breakdown of what it really contains.

Deep metadata

Container, video, audio, subtitle, chapter, and image streams — codecs, profiles, bit rates, color primaries, HDR, chroma, languages, and more.

Frame thumbnails

A grid of real frames decoded straight from the video stream, evenly spread across the timeline, with optional timecodes.

Cover art & posters

Embedded artwork is extracted losslessly from the container, displayed beside the metadata, and saved back to disk in its original bytes.

Archive-ready reports

Branded vector templates — a full archival report or a classic contact sheet, with your logo and custom fields. Export PDF or image, or print.

Private by design

Fully sandboxed and 100% offline. No analytics, no network access — your files never leave your Mac.

Truly native

A modern SwiftUI app built for Apple silicon and Intel. Fast, light, and at home on macOS.

Speaks your language

Fully localized in English, German, Spanish, Portuguese (Brazilian and European), and Russian.

1,500+ properties, your pick

Every property MediaInfo knows, with per-stream toggles for what shows on screen and what makes it into printed reports.

A batch at a time

Open a whole folder's worth of files — each stays in the sidebar with its format badges, one click from comparison.

Bitrate over time

One pass charts every stream's bitrate plus the container total — spot VBR spikes, starved sections, and encoding problems at a glance.

Fixity checksums

MD5 and SHA-256 computed in a single streaming pass — copy them, print them on reports, and carry them in every export.

JSON & CSV export

Machine-readable metadata with raw and formatted values and stable keys — ready for MAM ingest, catalogs, and spreadsheets.

Metadata

The truth, not the file extension

Media Inspector reads what's actually inside the container — every stream, every property — and formats each value the way humans read it: Mb/s, timecodes, byte sizes, dates.

  • Codec, profile & level, resolution, frame rate, scan type
  • Bit depth, chroma subsampling, color space, HDR metadata
  • Audio channels & layout, sample rate, compression mode
  • Subtitle tracks, chapters, and per-stream languages
  • Fixity checksums and a live bitrate graph, right on the Container tab

Thumbnails

See the content, not just the numbers

Frames are decoded directly from the video stream itself — no guesswork, no proxies — and laid out on an adjustable grid with frame-accurate timecodes.

  • Evenly distributed across the file's whole timeline
  • Adjustable thumbnail size, optional timecode overlay
  • Perfect for verifying content and spotting corruption

Reports

Reports worth printing

Turn any inspection into a crisp, vector PDF. Pick a template, tune it with live preview, then export as PDF or image, or print — every template renders true vector output, not screenshots.

  • Archival report — full metadata for every stream, with optional thumbnail pages
  • Thumbs sheet — a classic contact sheet with frame-accurate timecodes
  • Fixity checksums and the bitrate graph as first-page report cards
  • Brand it — your company name and logo on every page
  • Custom fields for facility, source media, catalog numbers…
  • Custom headers, paper size, orientation and margins
  • Prefer raw data? JSON, CSV, and plain-text exports are one menu away

Exports

Data that travels well

Reports are for people; exports are for pipelines. Every inspection leaves the app in whichever shape the next tool needs.

  • JSON — nested streams with raw and formatted values and stable keys, for MAM ingest and tooling
  • CSV — one flat table of every property, spreadsheet-ready
  • Plain text — the classic human-readable report
  • Computed checksums ride along in every export

Archives & collections

Built for people who keep media safe

Archival facilities, film and tape archives, post houses, and serious collectors — Media Inspector turns every ingest into documentation you can file, print, and trust.

Provenance on the page

Add your own fields to every report — facility, original media, catalog number, barcode — and they render as a dedicated card right below the file summary.

Verify every transfer

Confirm a digitization came out right — codec, bit rate, bit depth, color, HDR metadata — then seal it with MD5/SHA-256 fixity checksums before the source tape goes back on the shelf.

A visual fingerprint

Contact sheets give each asset a recognizable face — spot the right master at a glance and catch corrupted or black frames without scrubbing.

Your letterhead, not ours

Company name and logo on every page, plus a custom header line — reports look like they came from your facility, because they did.

PDF, image, paper

Export a vector PDF for the digital catalog, a high-resolution image for the MAM or the tape box, or print it and drop it in the physical file.

Safe for closed networks

Fully offline and sandboxed — nothing is uploaded, ever. Use it on air-gapped ingest stations and restricted facility networks with confidence.

Frequently asked questions

What file formats does Media Inspector support?

Everything its FFmpeg and MediaInfo engines can parse: MP4, MOV, MKV, WebM, AVI, MXF, MPEG-TS, and DVD-Video among the containers, with video codecs from H.264, HEVC, AV1, ProRes and VP9 to MPEG-2, and audio from Dolby TrueHD, Dolby Digital and DTS-HD to AAC, FLAC, Opus, MP3 and PCM. If a file plays somewhere, Media Inspector can almost certainly dissect it.

Is Media Inspector a MediaInfo app for the Mac?

Media Inspector is built on MediaInfoLib — the same open-source engine behind MediaInfo — wrapped in a fully native macOS app. It also goes beyond metadata: real decoded frame thumbnails, embedded cover-art extraction, and branded, print-ready PDF reports.

Do my files ever leave my Mac?

No. Media Inspector is fully sandboxed and works completely offline — it has no network access, no analytics, and no telemetry. Everything is analyzed locally on your machine.

Can it generate contact sheets?

Yes. The Thumbs Sheet report template lays real decoded frames on a page with frame-accurate timecodes and a file summary header, and exports as a vector PDF or a high-resolution JPEG image — ready for a MAM system, a catalog, or a printed folder.

Which metadata properties can it display?

Over 1,500 properties across container, video, audio, subtitle, chapter and image streams. You choose per stream type which properties appear on screen and which are included in printed reports.

Can it verify files with checksums (fixity)?

Yes. Media Inspector computes MD5 and SHA-256 in a single streaming pass — on demand or automatically on open — shows them on the Container tab, prints them on the archival report's Fixity card, and includes them in JSON and CSV exports.

Can it graph bitrate over time?

Yes. A single pass over the file charts the bitrate of every stream plus the container total — the combined graph on the Container tab, per-stream graphs on the Video and Audio tabs — and the graph can be included on the archival report.

Can I export the metadata as JSON or CSV?

Yes. Alongside PDF and plain-text reports, every inspection exports as machine-readable JSON (raw and formatted values with stable keys) or a flat CSV — ready for MAM ingest, catalogs, and spreadsheets.

Why is Media Inspector a good fit for archival facilities and film archives?

It turns every ingest into filing-ready documentation. The archival report template combines full per-stream metadata — enough to verify that a digitization came out right before the source tape goes back on the shelf — with custom provenance fields, your facility's branding, and optional thumbnail pages. The contact sheet gives every asset a recognizable visual fingerprint for the catalog, and both export as archivable PDF or image.

Can reports carry my company's branding and archival metadata?

Yes. Reports print your company name and logo on every page, plus an editable header line and a custom-fields card with a title of your choosing — name the fields anything your workflow needs (Facility, Original Media, Catalog Number, Barcode…) and their values render right below the file summary. Your template settings persist, so a whole collection gets consistent documentation.

Does it work on air-gapped or restricted facility networks?

Yes. Media Inspector has no network capability at all — analysis, reports, and exports all happen locally, so it behaves identically on ingest stations and QC workstations that never touch the internet. Nothing is uploaded, logged, or phoned home.

What are the system requirements, and what languages does it speak?

Media Inspector requires macOS 14 (Sonoma) or later and runs natively on both Apple silicon and Intel Macs. The app is localized in English, German, Spanish, Portuguese (Brazilian and European), and Russian.
