Definition
“Copy” is a standard communication term used on film sets—especially over walkie talkies—to acknowledge that you have received, understood, and will act on the information or instructions given. It’s the on-set equivalent of saying, “I hear you, I understand, and I’m on it.”
Clear, concise walkie communication keeps a set running efficiently, and “copy” is one of the most essential pieces of that vocabulary.
Purpose and Use
Film sets rely heavily on fast, reliable communication. Departments are often spread out over large spaces—multiple floors, distant exterior locations, trucks, holding areas, and unit bases. Walkies keep everyone connected, and responses need to be short and unambiguous.
“Copy” communicates the following in one word:
- Message received
- Message understood
- Action will be taken (if required)
This makes it a core part of on-set radio etiquette, used constantly by grips, electrics, ADs, camera team, transport, locations, and more.
When To Use “Copy”
On set, “copy” is appropriate when:
- You are confirming an instruction
- You are acknowledging information
- You are signaling readiness or comprehension
Examples:
- “Grips, fly in a 12-by.”
- “Copy, on our way.”
- “Locations, lock up the alley.” – “Copy.”
- “Camera is two minutes out.” – “Copy that.”
“Copy” helps keep channels free of unnecessary chatter while still confirming communication.
Variations
There are several related responses used on set:
- Copy That: Slightly more emphatic acknowledgment.
- 10-4: Borrowed from police codes; same meaning as “copy.”
- Roger / Roger That: Acknowledges receipt, commonly used with headsets or IFBs.
- Stand By: Means you heard the call, but cannot answer or act immediately—not the same as “copy.”
Understanding these variations helps you respond accurately without cluttering the channel.
Why It Matters
Walkie discipline is one of the most important but undervalued skills on a professional set. Using “copy” correctly:
- Prevents miscommunication
- Keeps channels clean
- Saves time and reduces errors
- Shows professionalism, especially for PAs, trainees, and junior crew
A fast, efficient set depends on clear communication, and “copy” is the backbone of that clarity.
