tuu recognizes the camera and the operator behind it, copies the card to your main drive and your backup drive at the same time, and checks every file on both. The tile turns green only when both copies are confirmed.
Built for DITs, video producers and event crews. Windows version in development.

tuu watches for new volumes. Camera cards are picked up on their own; your main and backup drives are never mistaken for one.
It reads the camera's serial number from the clips and looks up who shoots with it. A new camera is asked about once, then remembered.
The card is read once and written to both drives in parallel, into the right folder for production, operator and card number.
Both copies are read back from disk and compared by checksum. Green means both are confirmed. Now the card can go.
Plug in a card reader and tuu starts. Camera folder structures (DCIM, PRIVATE, CONTENTS, XDROOT, M4ROOT) and clips in the card root are recognized.
Serial numbers come from clip metadata via exiftool or from Sony and Canon XML sidecars. Each camera is linked to its operator once.
Recorders and drones that write no serial number are recognized by their folder and file pattern, such as a HyperDeck's device name.
One read of the card, two writes. Free space on both drives is checked before the first byte moves.
Every file is hashed with XXH3 while copying, then both copies are read back from the drives and compared. Not from cache, from disk.
Production, operator, card number. Numbering runs per operator and per production and continues where it left off.
Each card gets a fingerprint. Insert the same card again in the same production and tuu tells you it is already backed up instead of copying it twice.
A designed PDF report, an Excel sheet and a CSV with every card, operator, device, file count, size, paths and timestamps.
Hidden system files like .Spotlight-V100, .fseventsd and ._ files are left out of the copy and the fingerprint.
Turn on the Final Cut Pro handoff and tuu passes every verified card straight to Final Cut. The production becomes an event, and each operator and each card gets its own keyword collection.
Clips stay on your main drive, where tuu just verified them. Final Cut links to them instead of copying them a third time. You confirm the library once per import.
tuu builds Production / Operator / Operator_Card 01 on the main drive and mirrors it exactly on the backup. Every card folder carries the operator's name, so it stays clear even when it is moved or sent on its own.
An existing card folder is never overwritten. If a folder is already there, tuu stops and tells you.
At the end of the shoot, export the log for your client. Every card, who shot it, on which camera, how much data, where both copies live and when they were verified.
| Operator | Card | Device | Files | Size | Start | End | Status |
|---|---|---|---|---|---|---|---|
| Lena | 1 | Sony FX6 · SN 5012347 | 38 | 96.4 GB | 09:12 | 09:31 | Verified |
| Lena | 2 | Sony FX6 · SN 5012347 | 41 | 104.9 GB | 12:47 | 13:08 | Verified |
| Nils | 1 | Canon EOS C70 · SN 0331007 | 22 | 61.3 GB | 10:05 | 10:17 | Verified |
| Nils | 2 | Blackmagic HyperDeck Studio Mini | 1 | 177.4 MB | 17:37 | 17:37 | Verified |
Example data. The full report also lists folder, main path and backup path for every card.
tuu reads standard camera card layouts and clip metadata. Serial number support depends on what each model writes into its files.
Clip formats: MP4 · MOV · MXF · CRM · CR3 · BRAW · R3D · INSV · LRV
The same workflow for Windows workstations.
The client report as a PDF in one click, without going through the browser.
Optionally eject the card as soon as both copies are verified.
A signed Mac app that opens without security warnings.
Both run on two Macs, for example your editing station and your laptop on set. Pick what fits how often you shoot.

While copying, tuu computes an XXH3 checksum of every file on the card. After copying, it reads each file back from the main drive and from the backup drive and computes the checksum again. Only when all three match for every file does the card turn green.
Most cameras write their serial number into the clips or into sidecar files. tuu reads it, and the first time it sees a camera it asks you which operator it belongs to. From then on every card from that camera goes to that person's folder automatically.
Some recorders and drones write none. tuu then recognizes the device by its folder layout and file naming. Two identical units of the same model without serial numbers cannot be told apart; assign those cards manually.
Yes, with the Final Cut Pro add-on. After each verified card, tuu creates the event and keyword collections in Final Cut and links the clips on your main drive. Final Cut asks once which library to use. BRAW and R3D footage needs the Blackmagic or RED plugin in Final Cut, as with any manual import.
No. Two folders on one disk are not a backup. tuu checks that both targets sit on different physical drives and will not start otherwise.
A Mac with macOS and a card reader. tuu uses exiftool to read camera metadata. Windows support is in development.
No. tuu only reads from the card. Formatting stays your decision, in the camera, after the tile is green.
