How to rescue a talking head filmed in a moving vehicle
Tell Vizard Agent the recording was made in a moving vehicle. It measures the voice against the engine noise before applying any cleanup, grades around the light changing through the windows, and uses cutaways over the seconds that cannot be rescued, which is usually the honest answer for a few of them.
What do you type into Vizard Agent?
Describe the conditions, not just the fix. "Remove the background noise" is a filter; saying it was recorded on a moving bus, with the engine under everything and the light changing, tells Vizard Agent what it's dealing with. Say what the piece is about, too, because that decides which cutaways belong.
Prompt
What does Vizard Agent actually do?
All of the measuring happens before any processing, and that order stops the noise cleanup from eating the voice it's meant to rescue. Vehicle noise is several things, a low engine hum, road roar and vibration that arrives as thumps, and one filter doesn't address all three. In the session behind this article it:
- Inspected a piece to camera recorded on an overnight bus between two cities, checking the source details and the audio spectrum to see what the noise actually was.
- Transcribed the speaker with word timings and measured the voice and the background loudness separately before deciding on any processing.
- Found portrait cutaways of a sleeper bus, the Bali coastline, spices and herbal preparation, and downloaded each for the sections it would cover.
- Generated a calm ambient bed suited to the subject and loaded a verified text-behind-subject treatment for the opening, checking background-removal options for that shot.
- Generated clean animated captions in the speaker's own language.
When does this not work well?
Some vehicle recordings can't be recovered. If the engine is louder than the speech, the microphone clipped on every bump, or the speaker is backlit against a bright window for most of it, cleanup makes the damage more obvious rather than less. Heavy vibration blurs the picture as well as the sound.
Common questions
Can it remove the engine completely? Rarely, and Vizard Agent will not try if that would hollow out the voice.
Will the voice still sound like him? That is the point of measuring first. Vizard Agent aims for cleaner, not different.
Do I need to supply cutaways? No. Vizard Agent sources relevant footage, or uses yours if you have it.
