Free beta · macOS

Catch delivery problems before your client does.

Drop in your export. It checks the file against the delivery spec — loudness, codec, resolution, colour, and the signal QC most tools skip — and tells you exactly what to fix.

From dropped file to clean delivery — in 30 seconds.

Drop an export, watch every check run, fix the two problems it flags, and re-verify. This is the whole loop.

The 5pm problem

Deliveries bounce for the dumbest reasons.

Not the edit. The technicals. A number that's off by a hair, a tag that never got set — and the whole file comes back while the client waits.

✕Loudness −19.8 LUFS, spec wanted −14
✕Colour primaries not set — flagged on ingest
✕Audio at 44.1 kHz, delivery needs 48 kHz
✕A stray black frame at the tail, missed on export
What it checks

Everything a delivery spec cares about — read from the actual file.

Not the filename, not what the app thinks it exported. The embedded metadata and the real signal, measured.

01 · Loudness

The part most tools skip

Integrated LUFS and true peak, measured against the standard your delivery uses.

  • Integrated LUFS
  • True peak dBTP
  • LRA
  • EBU R128
  • ATSC A/85
  • −14 social
02 · Video

Format & colour

Codec, geometry, frame rate, and the colour tags that get files rejected.

  • Codec · profile
  • Resolution
  • Frame rate
  • Rec.709 / 2020
  • HDR · PQ · HLG
  • Chroma · bit depth
03 · Audio

Every track, checked

Codec, channels, sample rate and bit depth — including multi-track layouts.

  • Channels · layout

04 · Signal QC

What a metadata read can't see

A real decode pass that catches content problems in the picture and sound.

  • Black frames
  • Freezes
  • Silence
  • Clipping
Targets

50 delivery presets — or build your own.

From social cutdowns to broadcast masters. Each one shows its source and whether it's a verified standard or a baseline to confirm.

Need something specific? Build a custom target from any resolution × platform — 2K scope, IMAX 1.43, a client's exact frame — and validate against it in one click.

See it in action

A clear verdict, and a shareable proof.

Every check reads as PASS, WARN or FAIL with the actual-vs-required numbers and a fix. Export the whole thing as an image to send a client or teammate.

delivery report
A validation report showing pass, warn and fail rows with fixes

The report. Severity-ranked results, plain-English fixes, and the measured properties — one image you can hand off as proof.

spec library
The spec library with categorised delivery presets

The library. Filter by category, search, and validate one file against a whole set at once.

Pricing

Free while it’s in beta.

Every feature, no limits, no account. I’m building this in the open — use it on real deliveries and tell me what’s missing.

Early users keep it: if paid plans arrive later, everyone here in the beta stays free.

Made by one person, in the open. If it saves you a bounce, you can buy me a chai — completely optional.
