MediaLens Video Inspector & QA

【Never Fail a Media Delivery Again】

MediaLens is a professional, local-first media inspection and automated QA station built for video creators, post-production editors, colorists, and media engineers on macOS.

In professional video production, small metadata oversights lead to expensive rejections: incorrect color space tags (Rec.709 vs. BT.2020 PQ), missing audio channels, dropped subtitles, jittery frame rates, or web playback buffering due to a misplaced FastStart moov atom. Digging through pages of raw terminal outputs is error-prone, exhausting, and wastes turnaround time.

MediaLens transforms raw technical metadata into actionable quality decisions and client-ready proof.

### CORE FEATURES & PRO WORKFLOWS

1. Deep Single-File Media Inspection - Instant overview of container wrappers, file size, exact duration, stream tracks, and embedded metadata. - Comprehensive video parameters: resolution, frame rate (FPS), bitrate, color primaries, transfer characteristics, matrix coefficients, and chroma subsampling. - Smart Risk Diagnostics: automated alerts for missing audio tracks, duration discrepancies, inconsistent frame rates, or incomplete color tags. - One-click SHA-256 integrity checksum calculation.

2. Side-by-Side Multi-Version Diff - Compare up to 4 files side-by-side (Master Archive vs Web Proxy vs Platform Delivery). - Instant diff detection across file size, codecs, color profiles, audio channels, and subtitles. - Differences are highlighted clearly in red/amber; identical fields remain clean and organized.

3. Automated Batch Folder QA - Recursively audit entire project directories in seconds. Monitor progress with real-time pass/fail/review statuses. - Built-in delivery presets: • Standard Media Delivery • Web & Mobile Streaming • Editing Import Verification • Master Archival • Broadcast Master Standards • HDR Wide Color Gamut (Rec.2020 / PQ / HLG) • HLS & DASH Streaming Distribution - Smart incremental caching and pause/resume support for effortlessly scanning huge media libraries.

4. Container ISO Box Hierarchy & FastStart Verification - Visual ISO Box (Atom) tree browser for MP4, MOV, and M4V files (ftyp, moov, mvhd, trak, mdat). - FastStart Verification: verify that the moov atom is located before mdat to eliminate web buffering delays and black first-frames. - Inspect fragmented MP4 (fMP4) chunks and parse local HLS (.m3u8) and DASH (.mpd) manifests.

5. Client-Ready Delivery Reports - Export beautiful, standalone HTML delivery audit certificates ready for client sign-off. - Export structured JSON and tabular CSV reports for pipeline automation and studio archiving. - Home Path Redaction: automatically sanitize sensitive user directory paths before sharing reports outside your studio.
