Systems and methods are directed to acquiring, generating, manipulating and/or editing refocusable video data/frames. The refocusable video frames may be light field video frames that may be focused and/or refocused after acquisition or recording of such video frames. In one aspect, a method comprises: selecting a first key frame, wherein the first key frame corresponds to one of a plurality of refocusable light field video frames; selecting a second key frame, wherein the second key frame corresponds to one of the plurality of refocusable light field video frames which is temporally spaced apart from the first key frame such that a plurality of refocusable light field video frames are temporally disposed between the first and the second key frames; determining virtual focus parameters for the first key frame and the second key frame; and generating video data.
