Changelog

Version 3.4 November 2026

Reports, rebuilt: six purpose-built documents in a new Export Report window — and every measurement Media Inspector takes, now on paper. Plus audio checked in every sample, and HDR light levels held to what the file declares.

• Six reports, one window. QC Report, Spec Sheet, Archival Report, Contact Sheet, Delivery Manifest and Comparison Report, each built to answer one question — in a new three-pane Export Report window that now hosts the Text, JSON and CSV metadata exports too.
• A QC verdict you can sign. Check a file against any conformance policy and get PASS, PASS WITH WARNINGS or FAIL, every issue with what was actually found, and a sign-off block with signature lines and Approved / Rejected boxes.
• Measured vs. declared, on paper. Bit rate, loudness, true peak, MaxCLL and MaxFALL are measured from the essence and printed beside what the file claims — Matches, Differs by +160%, or Not declared.
• A spec sheet for clients. One page in plain words: a hero frame, a headline like “4K · HDR10 · 23.976 fps”, the picture and file details, and every audio and subtitle track — always exactly one page.
• Delivery manifests. Every file in one table, with totals, a pass / warn / fail tally and checksums in full — plus a CSV export with raw seconds and bytes for your spreadsheet or MAM.
• Comparison reports. Two or three files side by side, differences first — master against proxy, before and after a transcode — with an optional SHA-256 check for byte-identical copies.
• It measures for you. When a section needs loudness, light levels, bit rate or checksums, the measurement starts on its own and shows its progress. Exports wait for it, so a finished report never contains a placeholder.
• Your brand, every format. A brand kit in Settings — name, logo, accent color, contact line — styles every report. Export a vector PDF, PNG or JPEG pages, a self-contained HTML file that reads well on a phone, or CSV for tables.
• Reports in Shortcuts. Generate Report now takes a report type, a policy and a format — PDF, HTML or CSV. Manifests and comparisons turn every input file into one document, and existing shortcuts keep working.
• Audio integrity, measured. The analysis that draws the waveform and measures loudness now finds what metadata can't: silent or duplicated channels, mono phase cancellation, dropouts with their timecodes, and silence at the start, the end and in between.
• Honest HDR light levels. A new policy checks declared MaxCLL and MaxFALL against the measured picture: it fails files more than 10% brighter than they claim, and warns when the values look like boilerplate.
• A bigger policy library. Eighteen built-in policies in seven groups, now covering HD streaming masters, Dolby Vision profile 8, US broadcast and streaming loudness, and caption line limits for 608 and TTML.

Fixed

• Conformance rules on measured values read in plain words (“Loudness (measured)”) instead of internal codes, wherever rules appear.
• Exported page images are always tagged sRGB, instead of the main display's color profile.
• Reports made from Shortcuts, or for several files at once, include every measurement their options ask for — loudness and HDR light levels were missing.
• Properties with several values no longer end in a stray slash (“dvhe.08 /”) when one of them is empty.
• Files opened through a symbolic link show their real size in the JSON export and in checksum progress.
• New engines: FFmpeg 9.0.2 and MediaInfo 26.10, with their security fixes and better reading of MXF, MP3 and Opus.
• DTS:X tracks show their real speaker layout — 7.1.4 or 5.1.4, with the height channels listed.
• SDR files that carry mastering-display metadata are no longer labeled HDR10.
• HEVC video reports scan type, bit rate mode, maximum bit rate and buffer size, so policies on them evaluate.
• HDR light levels measure ProRes 4444 masters.
• Offline Macs keep working: a purchase verified within the last 30 days opens without a connection.
• Truncated MPEG-TS files no longer hang while reading.

Version 3.3 August 2026

Loudness metering, measured HDR light levels, full Dolby Vision colour, automatic analysis, and the essentials of every stream at a glance.

• EBU R128 loudness. Every audio stream now reports integrated loudness, loudness range and true peak — measured from the audio itself, with a short-term loudness curve.
• Measured HDR light levels. MaxCLL and MaxFALL are measured from the picture and shown next to the values the file declares, with a brightness timeline for the whole programme.
• Dolby Vision, in colour. Profile 5 files decode through the full Dolby Vision pipeline, so previews and thumbnails show true colour instead of the magenta cast other tools display.
• HDR thumbnails. Thumbnails from HDR sources display with real highlight range on HDR displays, and are tone-mapped correctly everywhere else.
• Quick stream facts. Every stream tab opens with the essentials — format, resolution, channels, bit rate, language, duration — so the basics never need a scroll.
• Smoother with long files. Switching between feature-length files is instant, live resizing stays smooth however much is on screen, HDR analysis is about ten times faster, and thumbnails arrive in a third of the time.
• Automatic analysis. Two opt-in switches run the measurements for you the moment a file opens: waveform, loudness and bitrate for every audio stream, HDR light levels for every video stream — cards already open.
• Timecode under the pointer. Hover any timeline chart and a dotted cursor shows the exact timecode at that point — spot something odd on a waveform and know precisely where to look.

Fixed

• Switching files no longer flashes the previous file's waveform or loudness curve.
• Dolby TrueHD in Matroska no longer measures about 0.85 LU too quiet, and multichannel WAV files without a channel mask no longer count the LFE toward loudness.
• Dolby Vision profile 5 thumbnails and light levels are no longer oversaturated: colors match the equivalent HDR10 encode, and measured MaxFALL no longer reads high.

Version 3.2.1 July 2026

Per-channel audio waveforms and much faster thumbnails.

• Audio waveforms. Every audio stream draws one waveform lane per channel with its peak level in dBFS, on the Audio tab and optionally in reports.
• Faster thumbnails. Hardware-accelerated decoding makes thumbnails up to 35× faster on transport streams and 2–3× faster on typical files.

Version 3.2 July 2026

The Facts tab, hardware thumbnails and two more languages.

• Facts tab. A plain-language summary of any file, with format badges and a storage breakdown.
• Japanese and Chinese. The app and its property catalogue are now localized in eight languages.
• Opening from Finder. Double-clicking a file and “Open With” now work reliably in every case.
• Sharper policy drafting. “New Policy from File” now surveys every stream, so mixed audio and video files draft correctly.

Fixed

• Opening files from the Finder works again — double-click, Open With, or dropping a file onto the app icon.
• Thumbnails for MPEG transport streams no longer take ages to generate.
• No more crash in the policy picker on macOS Sonoma, and the Facts tab's layout and storage chart are fixed.

Version 3.1 March 2026

Conformance policies, kind-level tabs and batch export.

• Conformance policies. Describe what your files should be and every file gets a pass/fail verdict, with a shareable policy document and a built-in starter library.
• Kind-level tabs. One Audio tab listing nine streams instead of nine tabs, with a sub-bar to move between them.
• Batch export. Select many files and export PDF, text, JSON or CSV for all of them at once.

Version 3.0 December 2025

Media Inspector 3: a new interface, a new engine, and reports.

• Built for modern macOS. A native macOS interface, with thumbnails that stream in as they decode instead of after indexing the whole file.
• Reports. Archival-grade PDF reports and thumbnail sheets, with live preview and printing.
• Shortcuts and checksums. Analyze files, compute MD5 and SHA-256, and generate reports straight from Shortcuts.
• A new engine. Decoding moved from FFmpeg 4.4 to FFmpeg 8.1 and metadata from MediaInfo 21.09 to 26.05 — years of new codecs, containers and HDR formats, recognized out of the box.
