1. A method for recompressing video data comprising:

  • acquiring a recompression parameter including a reduction rate of reducing a target bit rate of output video data with respect to a bit rate of input video data encoded in a first encode scheme;

    recompressing the input video data by a first transcoder including the first encode scheme and a first compressibility, if the reduction rate is smaller than a threshold value, to generate the output video data; and

    recompressing the input video data by a second encode scheme different from the first encode scheme and a second compressibility smaller than the first compressibility, if the reduction rate is not less than the threshold value, to generate the output video data.
