Errant: The Kinetic Propensity of Images is a project about the automatic analysis and visualization of motion in the cinema. It consists of a two-channel video projection. The left channel shows the decomposition of the optical flow of a shot into basic motion patterns. These motions are extracted using unsupervised machine learning methods. It is possible to reconstruct approximately the original shot's optical flow by combining those latent motions. The right channel shows the reconstruction of the optical flow.

The material consists of three films directed by King Hu 胡金銓:
A Touch of Zen 俠女 (1971)
Legend of the Mountain 山中傳奇 (1979)
Raining in the Mountain 空山靈雨 (1979)
