The trick to capturing pictures, and video, is to know where things are going to be and to put the camera up before they arrive. In the short term, this is a matter of luck, in the long term it becomes a matter of experience.
In winter, this is easier. Tracks in the snow provide some clues about what has been by, and where might be a good place to position a camera. As the snow piles deeper, the local wildlife is no more inclined to wade through it than we are, and cameras can be placed along cleared areas (such as plowed driveways) with greater success.
On the whole, getting good pictures and video requires luck, good camera placement, and wading through a great many bad photos and deer selfies.
