I’m recording a video course but unfortunately, the microphone and the camcorder don’t like each other pretty much. There’s always a background noise like in the first and last 5 seconds of this example (downloadable .mp3 in my dropbox with the noise and some words):
Thanks for your answer. They are round-about 18 videos… re-recording with lip-syncing would be more time-consuming than accepting an underwater sound or just reducing the cam sound slightly with noise reduction
But I guess I’ll try for fun whether lip-syncing is possible. First step to Hollywood
Bring strong coffee. It’s called “Looping” where a short segment of video (film) is presented over and over and the actor presents the lines repeatedly getting closer and closer to picture sync each pass.
Your sound recorder has automatic gain control—AGC. The good news is it will always record something and it doesn’t matter what your voice volume is. The bad news is it can’t tell the difference between voice and background noise.
It produces Noise Pumping.
I don’t understand how you got a video camera to make that much noise, unless the noise is really coming from your room and not the camera. Is that computer fan noise?
There is one possibility. Because of the way AGC works, the noise is never there at the same time as the voice. You might be able to use the Punch tools to “cover up” the beginning and ending noises without affecting the rest of the voice.
Thanks, I’ll try this and get back to the forum afterwards. That was my impression, too. One can only hear the camera when I’m not talking.
It’s definitely the combination camcorder - lapel microphone. I tried it with cable-bound microphones and the noise is a lot less.
In the future, I’ll use a different microphone or record the audio with the computer to lay it over the video afterwards.
I tried, but I don’t know if I did it correctly, but didn’t worked for my purpose. The first seconds were silenced, but there still were the noisy parts later in the track.
I tried the Punch Copy/Paste, but since English isn’t my mother tongue, it was a little bit hard to understand how it works. I guess I understood now, but it didn’t work the way I intended.
Thanks to all of you for your help!
My “solution”: I re-tried the noise reduction. From other videos, I copied ~15 seconds of the camera noise to get the reduction a better sample. After trying different settings, I finally found one that isn’t too disturbing and you still hear some camera sound, but I’ll just leave it like that now.
