A dependency-light Python script (standard library only) that sizes a subjective test DESIGN. From your number of sources (SRC), conditions (HRC), clip length, vote time, and fatigue-limited session length, it computes the full-factorial PVS count (SRC*HRC), the total voting time, the training and stabilizing-clip overhead, and the number of fatigue-limited sessions required; it flags when the design exceeds one session and suggests splitting; and it prints a ready-to-fill ITU-T P.910 §14 report

Fora Soft Video Engineering Handbook
This planner sizes a subjective test design from sources, conditions and clip length and flags when the test needs more than one session. Our seven-volume handbook covers the context for the test: Volume 1 on quality metrics and codec comparisons, Volume 3 on delivery QoE, and Volume 6 on AI quality models that rely on subjective data. Written by Nikolay Sapunov, CEO at Fora Soft.
