CardFlow

Summary

CardFlow is a professional camera card offload tool for macOS, providing photographers and DITs with full xxHash64 verification, ASC MHL v2 chain of custody, and PDF delivery reports. Insert card to start copying; every file is verified from destination to ensure complete delivery.

What is CardFlow?

CardFlow is a professional camera card backup and verification tool built for same-day photography, event production, and DIT workflows. The system re-reads every file from the destination and compares hash against source; only identical content is marked as verified. Pro edition offers DIT mode: preserves full card directory structure, creates ASC MHL v2 manifests, and exports PDF offload reports. Rust core engine balances speed and stability; supports macOS 14+ Apple Silicon.

Core Capabilities

• Full xxHash64 verification — reads source and calculates hash, writes to destination, re-reads from destination and calculates hash again, compares both to ensure match
• Dual-destination backup — one offload can write to two different disks, with separate hash verification for each destination
• Auto-skip verified files — when the same card is offloaded again, already-verified files are not re-copied; after continued shooting, only new content is processed
• DIT mode — preserves full card directory structure (DCIM, PRIVATE, AVF_INFO), creates ASC MHL v2 manifest and chain of custody
• PDF delivery reports — one-click export from History: source & destination volumes, Clips Overview, video format data, and per-file hash
• Camera identification — auto-detects camera model and serial number; even with identical models, serial distinguishes each body
• Flagged problem files — checks read errors and file structure anomalies (JPEG, RAW, MOV, MP4) during copy; flags individual files and retains in History
• Flexible sources — supports memory cards, SSDs, and HDD folders as sources; applies same verification and reporting workflow

Pros

• True verification complete — re-reads from destination and compares hash; green progress indicates verified data, not just written data
• Auditable delivery records — ASC MHL v2 manifest logs per-file xxHash64 and every offload result; subsequent offloads of the same card append to the same chain
• One-time license purchase — no monthly fee; license is perpetual; first year includes software updates, renewal available for continued updates
• Rust core engine — balances speed and stability; interface stays responsive; provides Traditional Chinese and English UI with real-time remaining time estimate
• Complete History records — every offload has full record; status color indicates result (green complete, yellow warning, red incomplete delivery, gray canceled); per-file detail view available

Positioning & best fit

CardFlow is built for professional photography and film production workflows that require auditable delivery records. Standard edition suits daily photography work with full hash verification and auto-skip of verified files; Pro edition provides full card structure, MHL, and PDF reports needed for DIT delivery.

• DIT and post-delivery teams — need ASC MHL v2 chain of custody and PDF offload reports to provide auditable delivery records to production
• Same-day photography and event production — need fast backup with full verification; after continued shooting, only new content is processed
• Multi-camera shoots — need to distinguish card sources by camera serial; alerts when card does not match previously bound body
• Workflows requiring dual-destination backup — one offload creates primary copy and safety backup, with separate verification for each destination
