Certain systems and methods are directed to acquiring, generating, manipulating and/or editing (for example, focusing or refocusing) 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 of comprises: (a) selecting a first key frame, wherein the first key frame corresponds to one of a plurality of refocusable light field video frames, (b) 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, (c) determining a virtual focus parameters for the first key frame and the second key frame, and (d) generating first video data corresponding to the plurality of refocusable light field video frames which are temporally disposed between the first and the second key frames using (i) the virtual focus parameter for the first key frame, (ii) the virtual focus parameter for the second key frame and (iii) the refocusable light field video data corresponding to the plurality of refocusable light field video frames which are temporally disposed between the first and the second key frames, wherein the first video data includes a plurality of video frames, each video frame including a virtual focus depth which is based on the virtual focus parameter(s) for the first key frame and/or the second key frame.
