A native Mac app for finishing & online artists, editors and QC teams: check a real file against what the platform actually requires — codec, raster, frame rate, colour, audio, loudness — and hand over a clean PDF QC report.

The curated spec library is the product — browse it with no file attached, then point Checkpoint at a real deliverable and let it do the checking.
Pick a platform and deliverable and see the exact tech spec — grouped by domain, with severity, guidance and a source citation.
Point at a real deliverable. The engine reads its metadata — codec, raster, frame rate, colour, audio, timecode — and scores it against the spec.
An opt-in decode pass measures loudness (LUFS / LRA / true peak) and scans for black and frozen frames.
Auto-verified rows sit beside manual checks (textless, A/V sync, illegal levels) — then export a print-ready PDF QC report.
See it in action
Browse the spec, attach a real file, and every parameter is scored pass / warn / fail — sources cited, nothing hidden.






A branded, per-parameter QC report — expected vs found, with an overall verdict — the deliverable you hand to production, post and the platform.

Everything scored against the chosen spec — no guessing, no spreadsheet, no separate tools.
223 curated delivery specs from 69 organisations across 24 countries and growing — streamers, broadcasters, theatrical and delivery standards — each rule with severity, guidance and a source citation. New platforms are added continuously, so the library keeps growing through Spec Updates.
Not in the library — or a house / client standard of your own? Create a custom preset with your own rules (fields, matchers, ranges). It lives under My Presets and verifies files exactly like a built-in spec.
Reads a deliverable's codec, raster, frame rate, colour, audio and timecode via AVFoundation, and flags every parameter pass / warn / fail. QuickTime & MP4 — ProRes, H.264, HEVC.
ITU-R BS.1770-4 / EBU R128 integrated LUFS, loudness range and 4× oversampled true peak — validated against the EBU Tech 3341 test signals.
The decode pass samples the picture for black frames and frozen frames, so silent delivery-killers surface before the platform's QC does.
Auto-verified rows sit alongside manual checkboxes — textless elements, A/V sync, illegal levels — for a complete, defensible sign-off.
A branded, per-parameter QC report with an overall verdict — the deliverable you hand to production, post and the platform.
Specs change. Optional Spec Updates keep the library refreshed as platforms revise their delivery requirements — and lapsing keeps every spec you already have.
Built from scratch with no third-party or proprietary code and no external binaries — fully App Sandbox-clean and Mac App Store native.
Where it fits
Checkpoint QC isn't another metadata viewer or scope. It answers a different question.
