Improvising to Videos

I am asking myself the question – how to improvise to videos? I have discovered that ‘free music’ sounds etc (for me anyway) easily fits into almost any video, at least much more that music with rhythm/melody. Why is this? I think its is partly because when listening to the music (free music) one can assign the sounds easily to different ares or aspect of the video – especially if there are many movements going on and, for me again especially, if its an abstract video or region within the video. I’m developing these thoughts and wonder what others think.

Maybe Im balmy?

Within this in mind I made this video recently and then overlayed my own sounds:
