Newbie to Audacity Help on Removing White Noise

I have a video with talking and sound in the background and I want to hear only the voices getting rid of the white noise. I have extracted the audio from the video. I saw something on vocal isolation wasn’t sure if this what would help on this project or is it just using noise reduction. Any help would be appreciated.
Thank you

Vocal isolation is supposed to bring-out the “center channel” vocals in a stereo recording. So noise reduction isn’t the purpose but it might actually help since the noise should be random in the left & right channels. But, it’s “heavy processing” and there can be artifacts (side effects) so you’d have to try it to see how it works in your situation.

But first, try [u]Noise Reduction[/u]. You feed-in a sample of noise-only and it tries to isolate the signal from the noise. But again there can be artifacts, especially if the noise is bad, so it’s something you just have to try. Noise Reduction works best when you have a constant very-low level background noise… When you don’t really need it.
