01 / 05
flow knows what has been copied.
All of it without touching the card: flow only reads the source, you format when you decide it is time.
More situations from set
Shooting day from the recording date.
The card knows whether it is Day 01 or Day 03. Footage shot past midnight splits into days, and a clip and its XML never land in two.
A card never overwrites a card.
The next card from the same camera goes into its own folder. The first copy stays in place.
One card, two projects.
A day already copied to another project is visible and unchecked. A click will not drop one client's footage into another client's folder.
Camera clock set wrong.
Correct the date before copying. The footage goes into the right shooting day.
You see the card before the Mac mounts it.
MacBook slot, USB reader, Blackmagic drive. flow shows the media and its reader, even when the card is empty.
Copying is the first step.
flow compares checksums for the source files and their copies. It saves the result in an ASC MHL report.

Copy, verification, report. Describe the process in your quote.
Copy the ready-to-use paragraph alongside.
"We ingest footage from set in a controlled process: we write a 1:1 copy to two independent drives, compute and compare xxHash64 checksums and save an ASC MHL report. Every ingest ends with a result we can verify, not with a declaration."
This wording assumes an active flow Pro plan, two target drives and a completed verification.

Before you format a card
What to check after offloading camera footage: file verification, a second copy and the ingest report.
