Digitization, defined as the capture of data into computable 1 and 0 s, is a freeze-frame process: a digital image, a piece of text, a video or audio file are a fixed set of data that is only rendered dynamic when it is read or played, or otherwise executed. What, therefore, are the implications of digitising movement? Digital technologies and methods employed for such digitization take a variety of forms, but broadly, they can be divided into two categories: those which capture and record motion directly (such as motion capture), and those which reconstruct it (such as GIS cost pathways). This chapter will consider and compare these two classes of approach. By considering them in the context of their “digital epistemology,” it will seek to situate these two highly complementary methods between performance studies and the digital humanities. By combining historical perspectives from both areas, the chapter will offer an evaluation of how the digital capture and recording of movement can contribute to our understandings of past environments and processes.
