MASTER COPY

Beta
Intense film production set

Data Loader Tool

Is Your Data Copy
Safe?

Copy complete. Verified. Zero worries.

Who Made This

Built by Filmmakers,
for Filmmakers

"As a cinematographer working on commercials and music videos, I've always questioned why data copying was a black box on set."

ALPS — Cinematographer / Developer

Did the copy actually complete? No one could be sure, yet we moved on to the next shoot.
I wanted to build a tool that truly serves filmmakers.
I still use it on my own productions and continue improving it.

The Problem

Sound Familiar?

Finder Copy Uncertainty

Copy finished, but is it really okay? Discovering file corruption during editing is irreversible.

Verification Takes Forever

Running verification after copy means waiting the same amount of time again. On set, that's not an option.

DIT Tools Are Expensive

Paying thousands for peace of mind? Not realistic for independent videographers.

The Solution

Why It's Faster

Concurrent Verification

Verifies data as it's read. When the copy finishes, verification is already done.

Guaranteed Writes

Bypasses OS cache. Confirms data is written to disk before moving on.

Fast Hashing

xxHash + Apple Silicon optimization. Hash calculation faster than disk I/O.

Benchmark

Proven with Real Data

200GB real production footage. Verified with zero additional wait time.

Master Copy with verification 3m 49s
Finder Copy + Separate Verification 4m 11s

Fastest, even with verification.

Pipeline verification eliminates additional wait time. Far more efficient than copying with Finder then verifying separately.

Frequently Asked Questions

What's the difference from Finder copy?
Finder just copies. Master Copy verifies while copying. When it's done, you're guaranteed the copy is correct.
Does it work on Intel Mac?
Yes, tested and confirmed. It's even faster on Apple Silicon (M1–M4).
What is MHL?
Media Hash List. An industry-standard hash list format for film production. Sometimes required for deliveries to Netflix and others. Master Copy generates it automatically.
Subscription or one-time purchase?
Planned as one-time purchase. Buy once and use that version forever.
Will it delete my original data?
Absolutely not. Master Copy is copy-only. It has no features that touch original files.
