Videos share most properties with images, because they are just image sequences. They can imported by dragging the file into the tree-view or the scene view.
Sequences of images can be imported by importing a sample, and changing the number with the symbol % in the file name.
You can download the sample image sequence here.
You can change the framerate by adjusting the property Time Multiplier in the section Time in the property inspector.
