Video aliasing

Aliasing / staircase artefact (high-frequency ratio)

What we measure and how

Aliasing score computed from the ratio of high-frequency to total spectral energy in the frame's Fourier domain. High values indicate insufficient anti-alias filtering during scaling. Reports the file's mean vs `aliasing_max_hf_ratio` from the spec.
