Funnily enough, I tend to edit my videos so that, from just before I start the props, through to them spooling up and the bird taking flight, the sound slowly fades out, and music slowly fades in. I then end the videos in the reverse, with the sound of the props slowly fading back in as the music fades out, and then stop the video just as the props cut out totally.
So I like the sound being recorded, but don't use a lot of it.
