How to reduce background noise from a video?

Profile picture of the author Entreprenette by
Hi guys,

I have a couple of video clips which have been recorded in quite a loud restaurant. I want to reduce the background noise a bit, but I don't want to completely remove it.

So far I can only find out how to remove it completely using Audacity. I tried this, but it left the sound really tinny and horrible.

Is there another way?

Thanks for your help.

Jo

    When you do it in Audacity make sure you do the minium noise removal.

    I've only used Audacity, apart from the noise removal feature in Camtasia. When using Audacity are you making sure to select a sample of the audio with just the noise only?

    Thanks for coming back to me. I have re-tried Audacity using minimal noise removal and I also had a go at izotope (thanks for that link, a very handy tool).

    However, once I had a reasonable audio file I then tried to import it back into imovie and there is no way to import just sound!

    Is that right, or am I missing something?? Mac imovie users - Help!

    Thanks

    I use Camtasia Studio, and it has a built-in noise removal tool that works great every time I use it. I don't know if that's something you want to look into, but it's practically a one-click process with little hassle.

    What did you save the sound file as?

    You should be able to import it. Same as sound effects that can be added. It can go on it's own timeline I believe.

    If you have a hundred bucks lying around I will suggest you grab screenflow though to edit with instead.

    Ok, I have imovie hd - but I was just able to go to file - import - and I selected an mpeg 4 file which filled itself in on the timeline automatically.

    Glad the izotope link worked for you. Once you have the fixed audio, import it into iTunes first, then when in iMovie click the music note icon in the right middle of the screen and from the drop down list, choose iTunes. You can then navigate to the file.

    I know with imovie, if you take the audio file and turn it into an mp3, you can upload it into imovie through itunes. Then you can just drage the audio track over the video and poof, you are up and running.

    Adobe Audition is what I use and the noise redcution facility allows control over the level of reduction - but costs!

    Guys, I have found the solution to the problem using Camtasia alone.

    Enable noise removal.

    Then click Advanced.

    The trick is to tick both Remove Clipping and Remove Clicks and set the Sentivity to 100 for both

    Absolutely no background or weird plumber sounds anymore. Just my voice.

    In fact, I found a much better background noise reduction when I had manually selected the background noise part (when I'm not talking). Do this by adjusting the green and red indicators to select the background noise region. Then click on 'Use manual noise selection'.

    PS: I did not enable voice (male / female) optimization. If I do that, a little background noise comes again.

    Note: Camtasia Version 7.1.0 was used.
