Statistical Properties¶

Complexity¶

To understand the nature of each test video. A similar plot has been made in UHD Video Encoding in CPU Versus GPU: Quality and Performance Trade-Offs.

mendevi plot ctc.db -x rms_time_diff -y rms_sobel -c ref_stem -m profile -s 'ref_stem=' ''

Energy per frame as a function of the number of frames during encoding

Reproduce¶

    for profile in sd hd fhd uhd4k; do
        mendevi prepare $video -p $profile
    done
