Card offload

Camera card offload for Mac and Windows, verified

A card offload is the moment footage leaves the camera card and lands on your drives. Until every copy is checked, the card is the only safe version. tuu makes that step boring: insert the card, and tuu copies, verifies and tells you when it is safe to format.

What a safe card offload needs

More than one copy. tuu writes the card to your main drive and every backup drive in one pass. Each drive must be its own disk.
Verification from the drive, not from memory. Every file is hashed with XXH3 while copying, then read back from each drive and compared. MD5, SHA-1, SHA-256, SHA-512, XXH32, XXH64, XXH128 and C4 can be added.
A clear green. The card only turns green when every copy on every drive matches. Then you can eject it and format it in the camera.
Proof. Each card folder gets an ASC MHL v2.0 manifest and an offload certificate, on every drive.

How a card offload works in tuu

Insert the card. tuu detects the card layout (DCIM, PRIVATE, CONTENTS, XDROOT, M4ROOT and more) and starts on its own.
tuu reads camera model and serial number and knows who shot it. A new camera is linked to its operator once.
The card is copied into your folder structure, for example Lena/Lena_Card 01, on every drive at once.
Every copy is read back and checked. Green means verified everywhere.

Cameras and recorders

ARRI, RED, Sony (including VENICE), Canon, Blackmagic, Phantom, Nikon, GoPro, DJI and Insta360 cameras – including cinema camera magazines that keep each clip in its own folder – and audio recorders from Sound Devices, Zoom, Tascam and others (Broadcast WAV with bext and iXML). Formats include MP4, MOV, MXF, ARRIRAW, R3D, BRAW, CRM, CINE, Codex ARX, N-RAW, CinemaDNG, CR3, INSV and WAV.

After the offload

A client report as PDF, Excel or CSV, a backup sync for everything else in the production folder, and an optional handoff to Final Cut Pro, Premiere Pro and DaVinci Resolve. More on the backups: camera card backup to several drives. Step by step: help.
