According to one embodiment of the present invention, a screen recording preparation method (100) for evaluating software usability using additional data (240) of a user session carried out by a computing system (300) comprises at least the following steps in an initial phase (IP): loading (110) a screen recording (200) comprising a number of N time-ordered screenshots (210) of the user session from a storage medium (310) and detecting (120) visual features within each of the N screenshots (210), wherein each of the features is attributed a position within the respective screenshot (210) and a score identifying the feature, and creating (130) a set of metadata containing an identifier of each of the N screenshots (210) and the features detected within each of the N screenshots (210) and setting (140) a threshold similarity value. The method (100) comprises a cycling phase (CP) treating the metadata with the following steps: comparing (150) a number of n consecutive screenshots (210) from an xthscreenshot (210) of the screen recording (200) onwards for similarity, wherein similar screenshots (210) have a similarity value deviation below the threshold similarity value, wherein the similarity value is based on the number of common features that have the same score within all of the n screenshots (210), for n ∈ {2, 3, 4, ... ,N-x+1} as long as the n screenshots (210) are similar and attributing (160) the n similar screenshots (210) to a screenshot cluster (220) and saving (170) information defining the screenshot cluster (220) to a storage medium (310) and reinitialising (175) the cycling phase, wherein x is replaced by x+n, as long as x+n ∈ {2, 3, 4, ... ,N-1}.According to further embodiments of the invention, a computing system, a computer program and a computer-readable storage medium are configured to perform a method according to an embodiment of the present invention.]
