Systems and procedures for transforming video into a condensed visual representation. An example procedure may include receiving video comprised of a plurality of frames. For each frame, the example procedure may create a first representation, reduced in one dimension, wherein a visual property of each pixel of the first representation is assigned by aggregating a visual property of the pixels of the frame having the same position in the unreduced dimension. The example procedure may further form a condensed visual representation including the first representations aligned along the reduced dimension according to an order of the frames in the video.
