Getting Started on Seatbelt

Your first transfer

Mon, 01 Jan 0001 00:00:00 +0000

Getting started with Seatbelt takes about ten seconds. Launch the app, drag a folder or a set of files onto the window, choose a destination, and press Transfer. Seatbelt copies every file, verifies it with a checksum, and shows you a clean summary when it’s done.

If anything goes wrong, like a read error, a permissions issue, a drive that disconnects mid-copy — Seatbelt will tell you exactly what happened and which files were affected. No silent failures.

Drag & drop workflow

Mon, 01 Jan 0001 00:00:00 +0000

Seatbelt is built around drag and drop. Drop files from Finder, from your desktop, or straight from a mounted camera card. You can drop multiple sources at once and Seatbelt will queue them in order.

Your most-used destinations are remembered automatically, so repeat jobs are just a drop and a click.

Supported formats

Seatbelt is format-agnostic — it transfers any file macOS can read. Camera RAW files (CR3, ARW, RAF, DNG), video rushes (MXF, BRAW, R3D, ProRes MOV), audio, documents, disk images — everything is treated the same way: copied and verified byte-for-byte.

Seatbelt also understands file sequences. A folder of numbered frames like IMG_0001.CR2 through IMG_0999.CR2 is recognised as a single logical group, making it easy to track large shoots at a glance.

Seatbelt vs Finder

Finder is heavily optimised by Apple and it’s fast. But it doesn’t verify what it copies, and when it runs into an error, it stops. If you’re not watching the screen at that moment, a stopped copy is easy to mistake for a finished one. On a busy offload on set, that can be a costly mistake.

Seatbelt is smarter. It verifies every single file using fast industry standard hashing, and gives you detailed, searchable logs for peace of mind. If a copy fails, you’ll know about it. And you’ll be able to quickly find the problem file or drive.
