Thats right, Blender allows you to animate (almost) everything that a user can manipulate. Including, oddly, the track assignment for a clip. Anyway here is proof that even a strip’s toggle switches can be keyframed. I chose flip x and color correction on/off. Then for good measure I added a noise modifier to the keyframes.

I added a bit of opacity noise too, just for good measure. I did have to change the strip’s blend type (at the top of the properties panel) to Replace, for the opacity to take effect. I guess you could apply the colour correction switch usefully to footage that has a alternate frame beat, say with flickering florescent lights, careful modification of the period using cycles modifier could help.

 

Have a play and show us how crazy you can get animating weird values!
