Abstract: A coding parameter computation device includes a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: decomposing an original video into scenes and selecting one scene of the decomposed scenes; generating encoded scenes by applying a plurality of combinations of bitrates and resolutions to the selected one scene; evaluating a quality of each of the encoded scenes; estimating, for the one scene, a relationship between a quitting ratio and a bitrate; obtaining quitting ratio values by applying the relationship to throughput historical data of the one scene; calculating N discrete quantization values of the quitting ratio values by applying a clustering algorithm; and identifying combinations of a bitrate, a resolution, and a quality value corresponding to the N discrete quantization values.
