I don't think this is the right forum for my question, but I hope that
someone with the necessary savvy can point me in the right direction.

I have a number of video files that I captured from a tape in my
camcorder, with the concourse of a Firewire board and Kino. In one of the
tapes the sound is pretty awful, in that there is a lot of background
noise (mostly wind) that makes all other sounds inaudible.

Anybody know of any tools that would allow me to remove that background
noise, so that the other sounds (mostly conversations) become audible?

Any pointers would be much appreciated.

If the files are in a format (avi or mjpeg or mpeg) that tools like
mjpegtools or avidemux can handle you could separate audio (e.g. with
lav2wav) from the video part, denoise that audio track (for example with
audacity) and then re-mplex them together.

The problem is that if the noise is very high you can't probably get rid
of it...

The 'compand'er in SoX can work pretty well. It won't be super
user-friendly because noise itself isn't. You'll have to
determine where in the dynamic range the noise exists and then
use the compander to reduce the gain of anything below the
majority of the noise. This has worked pretty well for me in the
past. So does audacity most of the time. But it requires a
section of the sound file with only noise in it in order to
calibrate its algorithm.

G'luck...
