Transfer Talk

Frequently asked questions you need to know before hitting transfer.

Who is Seatbelt for?

Seatbelt is made for creators who move a lot of data — filmmakers, editors, YouTubers, colorists, DITs.
If you work with large files, shoot on cards, and juggle external drives, Seatbelt gives you the confidence that your files actually made it — safely and cleanly.

Whether you’re offloading a camera card, copying media between SSDs, or archiving a finished cut, Seatbelt takes the guesswork out of the process.

Is Seatbelt faster than Finder?

Not always — Finder is heavily optimized by Apple. But Seatbelt is smarter.
Where Finder silently skips errors, Seatbelt verifies every single file using fast XXH64 hashing, and gives you detailed, human-readable logs for peace of mind.

If a copy fails, you’ll know about it — and see exactly which file was the problem.

What features make Seatbelt different?

Drag & drop simplicity – just drop files in and go
XXH64 hashing – cryptographic checksums for every file
Per-file and per-job logs – always know what transferred, when, and where
Grouped file sequences – treats IMG_0001.CR2 to IMG_0999.CR2 as one logical unit
Recent and most-used paths – get back to your usual folders instantly
Post-transfer hooks – trigger AppleScripts or custom workflows when a copy completes
Native macOS interface – built entirely in Swift, clean and responsive

Can I use Seatbelt for camera cards and offloads?

Absolutely. That’s one of its core use cases.
Just drag your folder or files from a CFExpress, SD card, or external SSD into Seatbelt, pick your destination, and hit transfer.
You’ll get speed, structure, and verification — every time.

Will it work with external drives and network shares?

Yes — Seatbelt works great with any volume macOS can mount: Thunderbolt SSDs, NAS volumes, USB drives, RAID arrays, etc.
It even remembers your most-used locations, so repeat jobs are faster to set up.

What does it cost?

Seatbelt is a one-time purchase — no subscription.
You get regular updates and support, and you’re backing an independent developer who actually uses the app.

Who built this?

Seatbelt is a one-person indie project.
No venture capital. No outsourced support. No bloat.
Just a fast, focused app — handcrafted by someone who lives and works in the same media trenches as you.
