this formula estimates the perceptual quality of digital video files by considering key properties that affect viewer experience. each factor in the formula scales in a specific way with changes in the underlying video file properties. below is a summarized description of how each factor influences the overall quality score.

• resolution factor: increases logarithmically with the video resolution. baseline: 640x480, 0.3072 megapixel
• frame rate factor: increases logarithmically with the frame rate. baseline: 30
• bit depth factor: increases logarithmically with the bit depth. baseline: 8
• bitrate factor: modeled using a sigmoid function relative to the optimal bitrate. baseline: resolution * bitdepth * framerate * codec_factor
• codec factor: adjusts the optimal bitrate based on codec efficiency relative to a baseline codec. baseline: h264
• quality score: additive aggregation with weighted contributions from each factor

the score is suitable for estimating quality in contexts where detailed subjective testing is impractical. furthermore, it can aid in decision-making for video encoding settings, streaming quality selection, or benchmarking.
