1. A video encoding method comprising:
storing quantized data of a plurality of frames which have undergone a quantization process by serially storing the quantized data of the plurality of frames on a per quantized data of one frame basis;
determining a quantization parameter to be used when a quantization process of a next frame immediately following the plurality of frames is performed, based on quantized data of at least one frame among the quantized data of the plurality of frames;
performing the quantization process of the next frame based on the quantization parameter to generate quantized data of the next frame; and
executing encoding processes for entropy encoding quantized data of a plurality of frames including the next frame in parallel between the plurality of frames including the next frame,
wherein, in the determining the quantization parameter, the quantization parameter is determined based on (i) an amount of encoded data of a first frame when an encoding process for entropy encoding quantized data of the first frame has been finished, and (ii) an amount of quantized data of a second frame when an encoding process for entropy encoding quantized data of the second frame has not been finished, the first frame and the second frame being included in the plurality of frames.
