-PRISM is a video encoder that embeds a clip by what is happening in it, not by where the
-camera is. It learns that split by recombining one clip's action with another clip's context
-in language, where such combinations come free.
+PRISM is a video encoder that captures viewpoint-invariant action semantics, matching the
+same action across egocentric and exocentric views. It decomposes each video into
+view-invariant and view-variant latents and recomposes them across videos under language
+supervision, which stays semantically valid beyond the co-occurrences observed in training.
