Catch the bounce before you upload.

A bounced delivery costs a re-render, a re-upload and a day of goodwill. Preflight batch-checks EXR headers, file naming and QuickTime codecs against the client's delivery spec - in your browser, before anything leaves the building.

The problem

Deliveries bounce on mechanical mistakes

The spec sheet is exact. Renders aren't.

Clients publish precise requirements - 16-bit half EXR, lossless compression only, contiguous frames from 1001, approved QT codecs. One artist's render settings drift and the whole package bounces on arrival.

The cost isn't the fix. It's the round trip.

A wrong compression setting takes minutes to fix - after you've discovered it. Add the multi-hour upload, the rejection email a day later, the re-render, the re-upload, and the note in the client's memory. Prevention is a ten-second scan.

Big shops script it. You shouldn't have to.

Facilities run in-house Python delivery checkers. Freelancers and small vendors get spot checks and hope. Enterprise QC suites exist - at hundreds of dollars a month or facility-level pricing. There was nothing at freelancer price. Now there is.

Features

Everything the rejection email would have said

EXR checks incl. ACES

Compression, bit depth, channels, resolution, pixel aspect, scanline-vs-tiled, embedded timecode and ACES (AP0) colour - from the first 64 KB, never the pixels.

DPX, TIFF & PNG headers

DPX bit depth and log-vs-linear transfer (catches a linear plate where the spec wants log), plus TIFF/PNG bit-depth and resolution - not just name checks.

Naming & frame checks

Padding, start frame, gaps inside sequences, mixed versions in one delivery, spaces and unsafe characters - against your token pattern.

QuickTime/ProRes checks

Codec identification (all six ProRes flavours), resolution and frame rate from container atoms - catches the accidental Proxy in a 4444 delivery. MXF is detected and flagged.

Spec presets + share

Six generic presets (streamer EXR pull, ACES, DPX 10-bit log, UHD, ProRes review) and a deep editor for your client's exact spec sheet - export/import a spec as JSON to share one ruleset across the studio.

Delivery manifest

A per-item manifest - type, resolution, codec/compression, bit depth, frame range, timecode - exactly what the recipient's ingest wants, as CSV or JSON.

Verdict + fix list

READY or NOT READY at the top, then a deduplicated fix list in plain English - not four hundred rows of the same error.

Reports for the delivery email

CSV for your records and a clean printable preflight report to attach - proof of diligence, dated, spec named.

How it works

Ten seconds between you and a clean upload

1

Pick the spec

Choose a preset or encode the client's spec sheet once - it saves for next time.

2

Scan the delivery folder

Headers and names are read locally. A 100 GB delivery takes seconds.

3

Fix, re-scan, upload

Work the fix list until the verdict says READY. Attach the report to the delivery email.

FAQ

Questions, answered

Does my footage upload anywhere?

No. EXR headers come from the first 64 KB of sampled frames; QuickTimes are read by container atoms. It all happens in your browser - pixels never leave your machine.

Which specs are included?

Generic presets modelled on publicly documented streamer-style requirements, plus a custom spec editor for the exact sheet your client sent. We are not affiliated with or endorsed by any streamer or studio.

What formats are checked?

EXR, DPX, TIFF and PNG image sequences and QuickTime/MP4 containers (all six ProRes flavours identified). MXF is detected and flagged for a manual look; full MXF essence parsing is on the roadmap.

What browser do I need?

Folder scanning works best in Chromium browsers (Chrome, Edge, Brave) via the File System Access API; others fall back to a basic folder picker.

Is a clean preflight a guarantee?

No - it checks headers and names, not pixel content or creative approval. It's built to catch the mechanical rejections that bounce deliveries most often.

Is there a free trial?

Yes - 14 days, no credit card, plus a one-click example delivery so you can see a full preflight report immediately.

Upload once. Deliver once.
