This article studies the transmedial process from the painting Nighthawks (1942) by Edward Hopper (the source medium) to the poem "Nighthawks" (2000) by Anne Carson and to two art GIFs created using the painting as a source (the target media). GIF is a file format that allows movement and an art GIF is a GIF which, in different ways, relates to an existing painting. The investigation is focused on repetition, which manifests in all three media products, and its effect on subjective time. Repetition can have different temporal effects in different media and can therefore be affected by transmediation. In literature, for example, repetition is often a way of slowing or stopping the temporal flow whereas, in painting, it can function both as a time stopper and as an index of movement and thereby temporal flow. Repetition in art GIFs is complex. Even though it represents the desire to add movement (and thus temporality) to a static image, it also halts time by not moving beyond the reiterated sequence it represents.
