What Is a Radio Cut?
A radio cut is an early edit of a film or video assembled from audio alone, with no attention paid to the picture, so the editor can hear whether the story holds together before spending time on visuals.
Close your eyes and listen to your rough cut. If the story still makes sense, if the argument lands and the emotion tracks, you have a working radio cut. If it falls apart the moment you stop watching, the structure is broken and no amount of pretty b-roll will save it.
That is the entire philosophy. Sound carries the story. Get the sound right first.
What a radio cut is
A radio cut, sometimes called a radio edit, is a stage in editing where you lay out all the audio in sequence, dialogue, interview answers, narration, and judge the piece purely on what you hear. The picture is an afterthought at this point. You are building the spine.
It earns its name honestly. The test is whether the cut would work as a radio program. No visuals, no graphics, no establishing shots. Just voices telling a story in an order that makes sense.
The radio cut is a kind of assembly edit, but a specific one driven strictly by sound. As one widely cited description puts it, a radio edit is 'a way to edit a project and tell the story by laying out all the audio first.'
Where it sits in the workflow
For talking-head heavy projects, the order usually runs like this: transcribe the footage, build a paper edit from the transcripts, turn the paper edit into a radio cut, then layer in picture to reach a rough cut, then refine to a fine cut, and finally lock.
So the radio cut is the bridge between the plan on paper and the first real timeline. It is where the abstract structure of the paper edit gets tested against actual recorded sound, with its real pauses, breaths, and pacing.
Why editors swear by it
The reason is brutal honesty. Visuals are seductive. A gorgeous drone shot can trick you into thinking a sequence works when the underlying story does not. Strip the picture away and you cannot hide behind production value. The story either holds or it does not.
It also saves enormous time. Cutting picture is slow. You sync, you choose angles, you find cutaways. If you do all that and then discover the structure is wrong, you throw the work away. The radio cut lets you fail cheap and fix the story while changes are still easy.
This is the same instinct behind audio-first editing in podcasts and the reason documentary editors transcribe before they cut. The words and the sound are the foundation. Everything visual is built on top.
A worked example
You are cutting a 12 minute documentary segment from three interviews and forty minutes of location sound. You start by pulling the strongest answers into a sequence on the timeline, audio only, arranged to make an argument: the problem, the turn, the resolution.
You play it back with your eyes closed. The middle sags. Two interviewees make the same point back to back, which feels repetitive, and the emotional payoff arrives too early, so the ending has nowhere to go. None of that was obvious on paper. It is obvious the second you just listen.
You cut one redundant answer, move the payoff to the end, and tighten a rambling setup. Now it plays. Only then do you start adding picture, knowing the spine is solid. You did not waste a single hour syncing footage to a structure that was going to change.
Radio cut versus rough cut
People mix these up. A radio cut is audio only and exists to test structure. A rough cut includes picture and is the first version that actually resembles the finished film. The radio cut comes first and feeds the rough cut.
Think of it as a staircase. Assembly and radio cut establish the order. Rough cut adds the visuals. Fine cut polishes timing and rhythm. Picture lock freezes it for sound mixing and color.
Common mistakes
The first mistake is skipping it. Editors who jump straight to cutting picture often build beautiful sequences on broken foundations, then have to tear them apart late, when changes are expensive.
The second is letting redundancy survive. On audio alone, two people making the same point is glaring. Cut the weaker one. The radio cut is where you find that kind of fat.
The third is manufacturing meaning while you rearrange. Reordering whole answers to build a clear argument is exactly what a radio cut is for. Splicing fragments of different sentences together to make someone say something they did not is a frankenbite, and it is an ethics problem, not an editing technique.
How this connects to the pre-edit
The radio cut lives in the pre-edit, the work that happens before you build the finished timeline. ScriptCut is designed for exactly this stage: you transcribe the footage, highlight the strongest spoken moments, arrange them into a sequence, and play any clip to hear how it sounds before you commit. Because every selected line carries word-level timecode, your audio-first structure exports as a real timeline to Resolve, Premiere, or Final Cut, so the radio cut you hear is the rough cut you start building.

Frequently asked questions
What is a radio cut in editing?
A radio cut is an early edit assembled from audio alone, with no picture, so the editor can judge whether the story works on sound. The test is simple: if it holds together with your eyes closed, the structure is sound.
What is the difference between a radio cut and a rough cut?
A radio cut is audio only and tests structure. A rough cut includes picture and is the first version that resembles the finished film. The radio cut comes first and feeds the rough cut.
Why do documentary editors make a radio cut?
Because sound carries the story. Building the audio spine first reveals pacing and structure problems early, when they are cheap to fix, before any time is spent syncing and choosing visuals.
Is a radio cut the same as a paper edit?
No. A paper edit is a plan built from printed transcripts before touching the timeline. A radio cut is the next step, where you actually assemble the audio and listen to whether the plan works.
