BitMatch
What it is
BitMatch copies camera-card footage to multiple drives and verifies each copy, helping users decide when a card is safe to erase. It is free software for indie filmmakers, YouTubers, photographers, and small productions, with iOS and macOS listed as platforms. Standard verification checks destinations with SHA-256. Thorough mode rereads the source and adds MD5, while Paranoid compares every byte using SHA-256. Camera detection includes Sony, Canon, ARRI, RED, Blackmagic, Panasonic, Fujifilm, GoPro, DJI, Insta360, and generic DCIM. Transfer results can be exported as PDF, CSV, and JSON on Mac, iPad, and iPhone. Verified copies receive an ASC MHL inventory by default, which can be disabled in Advanced settings. Mac also supports optional SFTP uploads after local verification; the server must provide SFTP and SSH shell access, and S3 and WebDAV are unavailable. The app reads the source without writing to it and avoids overwriting conflicting destination files. The project describes BitMatch as beta software and notes that it has not tested every hardware, filesystem, and OS combination.
For and against

- Detects a wide range of camera systems
- Exports reports as PDF, CSV, and JSON
- Reads source media without writing to it
Against
- Beta software from a one-person project
- Not every device and configuration has been tested
- Remote backup supports SFTP, not S3 or WebDAV
The verdict
BitMatch offers multiple ways to verify camera-card copies, plus reports and optional SFTP backup on Mac. Its beta status and untested hardware combinations are worth considering before relying on it in a workflow.
Who it suits
BitMatch is aimed at filmmakers, YouTubers, photographers, and small production teams who copy camera footage to multiple drives. Its verification modes and reports may suit users who want to check transfers before clearing a card.
