Do you mean whether including a video instead of an image or nothing affects the ranking of a page? I do not think it does.

We have listed video and audio feeds as separate (but equal) features, normally coded as present or absent. 

I would believe it, but do they have measurable effect on ranking? I guess it would be too difficult to verify whether adding such features have measurable effects, though they certainly affect the ranking of the "Video" and maybe "Images" tab.
