How do you reduce wind gust sounds from video?
Two possible ideas. When writing this answering I'm thinking in terms of the capabilities provided by Audacity but I think the same concept will work with other software.

Pick a silent part of the video with only the wind sound but no other sounds that you would like to keep, select that as the noise profile then apply noise reduction whenever there is the wind noise.

Apply a high pass filter to the audio. This will help reduce the effects of the wind noise. Again consider only applying this when there is wind.
