Abstract
Qualitative research that focuses on social interaction and talk has been increasingly based, for good reason, on collections of audiovisual recordings in which 2D flat-screen video and mono/stereo audio are the dominant recording media. This article argues that the future of ‘video’ in video-based qualitative studies will move away from ‘dumb’ flat pixels in a 2D screen. Instead, volumetric performance capture and immersive performative replay rely on a procedural camera/spectator-independent representation of a dynamic real or virtual volumetric space over time. It affords analytical practices of re-enactment – shadowing or redoing modes of seeing/listening as an active spectation for ‘another next first time’ – which play on the tense relationships between live performance, observability, spectatorship and documentation. Three examples illustrate how naturally occurring social interaction and settings can be captured volumetrically and re-enacted immersively in virtual reality (VR) and what this means for data integrity, evidential adequacy and qualitative analysis.
