There was a founder who shot a whole product demo against a bright window with the camera's own mic. The raw footage mistakes that cost the most to fix are unusable audio, no cutaway coverage, exposure that drifts shot to shot, and no B-roll. Each one turns a two-hour edit into a two-day one.
I have been briefing shoots and cleaning up the results for about nine years. The pattern is boring and consistent. The expensive edits are rarely expensive because the story was hard. They are expensive because the footage arrived broken in a way that only a person sitting in the timeline discovers, long after everyone has gone home (see Video Edit vs. Video Production: What's the Difference?).
Why does bad audio cost the most to fix?
Bad audio costs the most because there is often nothing to fix. Video you can color-grade, crop, and stabilize. Audio recorded off a camera mic in a room with an air conditioner is frequently gone, and re-recording means getting the person back.
The usual culprits: camera-mic sound instead of a lavalier or shotgun, a fan or fridge humming under every line, and clipping when someone laughs into a hot mic. A denoiser can pull a light hiss down. It cannot invent the mid-range that a bad mic never captured, and heavy noise reduction leaves voices sounding like they are talking through a tube.
The most expensive sentence in any edit is "can you clean up the audio." Sometimes the honest answer is no, and the reshoot costs more than the whole original shoot.
Budget-wise, a decent lavalier mic runs about $30 to $200 and a recorder maybe $150. That is a rounding error against a half-day reshoot at $800 to $2,500. Rode publishes a good plain-language explainer on why an on-camera mic is the weakest option (rode.com). Get sound off the camera and monitor it with headphones while recording. If you can hear the hum, so will everyone.
What happens in the edit when there are no cutaways?
Without cutaways, an editor cannot shorten anything without a visible jump cut. Every trim you want to make later is blocked because the picture jumps and the viewer sees the seam.
A cutaway is any shot that is not the main talking head: hands on a keyboard, the product on a table, a wide of the room, the interviewer nodding. You use them to hide edits. When you cut two sentences out of an answer, the person's head snaps position. Lay a cutaway over that moment and the cut disappears. No coverage means the editor is stuck with either the jump cut or keeping every rambling pause.
This is the single most common thing I flag on client footage. People shoot the interview and forget the coverage, then ask why the final video feels slow. It feels slow because I could not tighten it. Wikipedia has a clean definition of the concept if you want to send it to a shooter (B-roll).
On set this costs five minutes. After the main take, shoot 30 to 60 seconds of the person's hands, the screen, and a couple of wide angles. That is the entire fix.
Why does inconsistent exposure double the grading time?
Inconsistent exposure doubles grading time because the colorist has to match every shot by hand instead of applying one look across the whole video. When clips are shot at different brightness, a single grade makes half of them look wrong.
Auto-exposure is the usual cause. The camera hunts every time the subject moves or a cloud passes, so a static interview breathes brighter and darker across one answer. Mixed lighting is the other one: someone sits half in window light and half in a warm lamp, and now the skin tone shifts mid-sentence.
Here is roughly how the cost stacks up.
| Problem on set | 30-second on-set fix | Cost if it lands in the edit |
|---|---|---|
| Auto-exposure hunting | Lock manual exposure | 2 to 4 hours of shot-by-shot matching |
| Mixed window plus lamp light | Kill one source, pick one | Skin tones that never fully match |
| No white balance set | Set a custom white balance | Green or orange cast on every clip |
| Filming into a window | Turn the subject 90 degrees | Silhouette, unrecoverable highlights |
Lock exposure manually and pick one dominant light source. A flat, even setup is faster to shoot and hours faster to grade.
How does missing B-roll inflate the final bill?
Missing B-roll inflates the bill because the editor either builds motion graphics to fill the gaps or leaves the video looking thin, and the first option is billable design time. B-roll is the supporting footage that shows what the person is talking about.
Someone says "our warehouse ships hundreds of orders a day" and there is no shot of the warehouse. Now I have three options: hold on the talking head and hope nobody drifts, buy a stock clip that never quite matches, or animate something. Animation is real hours. A 60-second explainer that should cost one to two edit days can balloon to four or five when I am building visuals the shoot did not capture (see How Long a Video Edit Actually Takes and Why).
Stock footage is not free either. A single licensed clip runs $50 to $200, and it always looks like stock because it is somebody else's warehouse. Adobe and other editors have written plenty on how coverage drives edit pace, and it lines up with what I see: the shows that cut fast are the ones with a deep B-roll bin. Shoot the thing you mention. If you say it, show it.
What is the short pre-shoot checklist that prevents all of this?
The checklist is five lines, and running it costs about ten minutes before you roll. Every item on it maps to one of the expensive problems above.
- Audio: mic off the camera, headphones on, kill any hum you can hear. Record a 10-second test and actually listen back.
- Cutaways: after every main take, grab 30 to 60 seconds of hands, product, and two wide angles.
- Exposure: lock it manually, set a custom white balance, do not let the camera decide.
- Lighting: one dominant source, subject turned away from any bright window.
- B-roll: list what the script mentions out loud, then shoot each of those things.
I keep this taped to the inside of a gear case. It is not sophisticated. It just catches the four things that generate 80 percent of the extra edit hours I bill. If you are hiring a studio for the shoot and the edit, ask whether they capture coverage as standard. If you are shooting it yourself and sending us the files, this list is what keeps your quote where it started. You can see how we work at https://subsecondstudio.com (see What to Send a Freelance Video Editor Before the First Call).
One more thing that is not on the card but matters: shoot ten seconds of room tone, meaning silence in the space with nobody talking. It gives the editor a clean bed to patch audio gaps. Nobody remembers it and everybody needs it.
FAQ
Can an editor really not fix bad audio?
Sometimes, not always. Light hiss and background hum can be reduced. What cannot be recovered is missing frequency range from a poor mic or heavy clipping from a signal that was too loud. When the source is that damaged, re-recording is the only real fix, which is why on-set audio is the highest-leverage thing to get right.
How much B-roll should I shoot for a short video?
A rough rule is two to three times your final runtime in coverage. For a 60-second video, aim for two to three minutes of B-roll and cutaways across several subjects. It feels like too much on set and is exactly enough in the timeline.
Does better raw footage actually lower the edit cost?
Yes, directly. Clean audio, locked exposure, and real coverage remove the two things that pad an edit: manual shot matching and building visuals to cover gaps. A well-shot 60-second video is often a one to two day edit. The same length shot badly can run four to five. The savings show up on the invoice, not just the timeline.
