A method for encoding video signals including a first step of generating the information on picture characteristics at least including the luminance information of the input video signals in terms of a pre-set time interval as a unit, a second step of calculating the mean bit rate of the input video signals, a third step of calculating the information on the amount of bits generated per pre-set time interval of the input video signals, a fourth step of calculating the encoding difficulty per pre-set time interval based upon the information on picture characteristics, information on the amount of generated bits and the information on the total amount of usable data, a fifth step of determining the encoding bit rate per pre-set time interval by applying the encoding difficulty to a function for finding the encoding bit rate pre-set by the mean bit rate and a sixth step of encoding the input video signals in accordance with the encoding bit rate obtained per said pre-set time interval.
