What is a radio cut?

The test every interview-driven film has to pass: does the story hold up when you can only hear it?

Why cut for the ear first?

Because in interview-driven filmmaking, the voices carry the narrative load. Viewers follow a documentary primarily through what people say; picture confirms, colors, and deepens, but it rarely rescues a spoken story that doesn't track. Cutting audio-first exposes the structural problems while they're still cheap to fix — a missing piece of context, two subjects contradicting each other without payoff, an ending that arrives before the argument does.

It's also a defense against self-deception. B-roll, music, and montage are anesthetics: they can make a broken sequence feel finished. A radio cut removes the anesthetic. Editors who listen to their assembly on a walk, screen off, tend to hear the sag in minute fourteen that looked fine on a monitor. The discipline is old and simple — close your eyes; if you're still interested, the film is working.

Where does a radio cut sit in the workflow?

1. Start from marked material. Transcripts get read and annotated — often as a full paper edit — or selects get flagged directly in the footage.
2. Sequence the voices. Arrange the chosen bites into narrative order in the timeline: setup, complication, turn, resolution. Whatever picture rides along with the interview clips is tolerated, not designed.
3. Listen, don't watch. Play the sequence with the monitor dark or your back turned. Note every point where attention drops, logic jumps, or a voice repeats itself.
4. Restructure until the audio flows. Swap bites, cut redundancy, move the strongest voice earlier. Changes at this stage cost minutes, not days.
5. Then dress the picture. Once the radio cut plays, layer b-roll, archival, and music over it — the audio spine becomes the rough cut's skeleton.

Where did the term come from?

From radio, literally. Broadcast and public-radio documentary producers built entire programs from interview tape and narration, and their structural craft — the ordering of voices, the handoff between speakers, the reveal held for the right moment — migrated into television and film documentary along with the people who practiced it. Calling the audio-first assembly a "radio cut" acknowledges the debt: it is the version of the film a radio producer could broadcast as-is.

The technique remains standard on oral-history projects, branded interview films, and episodic documentary, and it has an obvious kinship with podcasting, where the radio cut simply is the deliverable. Some editors say "A-roll cut" or "audio assembly" for roughly the same object; the eyes-closed test is what defines it, not the label.
