Clearance, Coverage and Clean Audio: Three Terms Behind Reading Source Footage
Before the first cut, three trade terms decide what you can use: clearance, coverage and clean audio. Here is what each one means in plain words and how to check it.

Why the checking comes before the cutting
New editors tend to open a project, drag the first promising clip onto the timeline and start trimming. Most of the problems I see in feedback rounds were already baked into the recordings before that first cut, and nobody had looked at them. Reading source footage is the habit of examining what you have been given before you decide what to make from it.
Three terms come up constantly when we do this: clearance, coverage and clean audio. They sound like jargon, but each one is a simple question. Can we use this? Do we have enough of the right material? Can people hear what was said? This article takes them one at a time, in the order I check them on a new project during these mid autumn weeks, when many teams are sitting on recordings from summer and early fall events.
Clearance: do you have permission to use it
Clearance is the trade word for permission. A recording is cleared when the people who own or appear in it have agreed to the use you plan. For an event highlight, that usually means the organiser has authorised the recording and the speakers know it may be shortened and shared.
In our course every sample project is labelled with what it permits, and we ask learners to treat their own footage the same way. Before you edit, find out who recorded it, who approved the recording, and where the finished video is meant to appear. A recording made for internal review may not be fine for a public page.
If the answer is unclear, ask the organiser in writing and keep the reply with the project files. It takes five minutes and saves you from re-editing or withdrawing a video later.
- Who recorded the event and who authorised it
- Whether speakers and guests know the recording may be shared
- Where the finished video will be published
Coverage: what the cameras actually caught
Coverage describes how completely the recordings capture an event: which sessions, which angles, which moments. Good coverage means you can choose between options. Thin coverage means you cut with what exists, even if the best moment was filmed from the back of the room with the speaker half out of frame.
Scan the material before you plan anything. Note which parts of the event have more than one angle, where there are gaps, and whether the opening, the closing and the audience reactions were caught at all. A recap without a beginning or an end is hard to shape, and it is better to know that on day one.
Keep a simple log with timecodes and a one-line note for each stretch of footage. Daniel's rule in feedback sessions is that if you cannot describe a clip in one line, you have not really watched it yet.
Clean audio: can every word be understood
Clean audio means speech that is clear, steady and free of distracting noise. It matters more than most beginners expect, because viewers forgive a soft image far sooner than a muffled sentence. If a speaker cannot be understood, the clip is rarely worth keeping, however good the moment looked.
Listen on headphones, then again on a phone speaker, since many people will watch that way. Mark clipping, wind, room echo, music that drowns the voice and sections where levels jump. Also check that audio and picture stay in sync across the whole recording, not just at the start.
Be honest about what editing can fix. Small level differences and low hum can be improved. A voice recorded far from the microphone in a loud hall usually cannot be rescued, and the better choice is to leave that moment out or cover it with a clear caption placed carefully.
- Listen on headphones and on a phone speaker
- Mark noise, echo, clipping and sudden level changes
- Confirm sync holds from start to end
A short check you can run on any recording
Put the three terms together and you have a quick routine. First confirm clearance, so nothing you build later has to be taken apart. Then log coverage, so you know the real shape of the material. Finally mark audio quality clip by clip, so your selection already favours what people can hear.
This routine does not make the edit for you, but it changes the edit. When you reach clip selection you are choosing from a labelled list, not hunting through hours of video. You also know early which moments cannot be used and why, which keeps the conversation with the organiser short and factual.
Learners who do this check usually finish the later modules faster, because their questions arrive earlier and are smaller. Instead of asking why a clip feels wrong, they can say it fails on audio, or that coverage ends before the closing remarks.
Keeping meaning intact from the first look
Reading footage is also where respect for the source begins. When you watch a speaker closely before cutting, you learn what they were actually arguing, where a sentence builds to its point and which remark depends on the one before it. That knowledge is what lets you shorten without distorting.
Make a note of any comment that only makes sense with its lead-in, or any joke that needs its setup. Those are the places where a careless trim changes the meaning, and they are easier to protect when you have flagged them before editing starts.
This is the same value we return to throughout the course: respect the source. Clearance, coverage and clean audio are not paperwork. They are the practical ways of showing that respect before a single clip lands on the timeline.
Clearance, coverage and clean audio are three plain questions: can we use it, do we have enough, and can people hear it. Answer them before you edit and the rest of the process gets calmer. Your selections are better informed, your conversations with organisers are shorter, and the finished highlight stays faithful to what was actually said. Start your next project with a log, not a cut.
