Abstract
Provided are methods and apparatuses for performing motion estimation encoding and decoding on a video. A method of encoding a video includes splitting a picture by using a maximum coding unit; splitting the maximum coding unit into prediction units, according to a split mode indicating a split form of the maximum coding unit; performing motion estimation on a prediction unit having a size equal to or less than a predetermined size from among the prediction units included in the maximum coding unit, and obtaining a motion vector of the prediction unit having the size equal to or less than the predetermined size; and obtaining a motion vector of a prediction unit having a size greater than the predetermined size, by using the motion vector of the prediction unit having the size equal to or less than the predetermined size.
