How to make a factory tour video when the machines are too loud
Upload the whole walk-through and name the stages. Vizard Agent keeps only the lines that are genuinely audible over the machinery, uses everything else as picture with captions, and cuts the whole process, from intake to finished product, into something short. It doesn't fight to clean audio the machines have drowned.
What do you type into Vizard Agent?
State the audio rule in the brief, before anything else. Otherwise Vizard Agent will try to salvage the drowned lines with noise reduction, which gives a thin, obviously processed voice. Name the stages in order, because the process is the structure, and say who the video is for, because the jargon level follows from that.
Prompt
What does Vizard Agent actually do?
The first half of the job is finding out what is on the tape: where each stage appears and which lines can actually be heard. Vizard Agent then decides shot by shot whether the speech carries. The lines that don't become picture with a caption, which is what a broadcast editor does in the same situation. In the session behind this article it:
- Read the client's project history and reviewed frames from their previous video to match its style.
- Transcribed the speech and built a shot map of the whole recording, a 2364-second (39-minute) underground winery tour filmed at 1080x1920 and 30fps.
- Made a lightweight copy for visual analysis and searched it for each stage, from the floor, intake and sorting to the tanks, concrete vessels, tasting and cellar, retrying the one search that failed.
- Reviewed extracted frames of every stage, narrowed them to the best shots and checked which speech was intelligible.
- Checked the caption and music tools for the parts that would run silent, then cut a vertical Reel of up to 45 seconds covering the whole process.
When does this not work well?
A process video can only show the stages that were actually filmed, and a walk-through tour tends to skip whatever machine wasn't running that day. Footage that is loud all the way through leaves nothing usable as speech, a wandering tour has to be rebuilt into order in the edit, and some stages may only get two seconds.
Common questions
Can it clean up the noisy audio? Somewhat, but it usually shouldn't. Vizard Agent prefers captions to a processed voice.
How long can the source be? As long as the tour. Vizard Agent mapped a thirty-nine-minute walk-through here.
Will it find each stage? Yes, if it was filmed. Vizard Agent searches the shot map for each stage you name.
