This paper will examine how animated avatar-based interviews in online games can be in a documentary, which play an important role as the visual research data or form in an ethnography approach. This animated interview is conducted to investigate the issue of the construction of the contemporary identity of the Korean youth, and their ‘avatar' lives (as virtual game characters) and culture in animated online games, such as Massively Multiplayer Online Role-playing Games (MMORPGs). In this proposed discussion, I will offer virtual research methods which are applied to my visual practice, using records of avatar-based interviews and participant observation in Korean MMORPGs in relation to ethnography and virtual worlds. This paper will interrogate how these recorded auto-created animations of online practice can be engaged with an animated documentary in ethnography in virtual and real worlds, compared with self-created animation in a non-fiction context. For this reason, I will briefly introduce how the recorded auto-animated documentary is used to produce or purpose the primary data by online practice in a ‘visually based ethnography'. This animated practice engages with specific Korean youth identity, comparing the ‘avatar' with the real lives of participants. Importantly, this paper will mainly indicates the (ethnographic) research method, using the auto-created animated documentary, but not particularly present the meaning of the specific case of 'Korean-ness'. Eventually, this paper will propose new possibilities of auto-animated documentaries in a different or another mode of animated representation between animation and reality. This will facilitate explicating the unknown truth or question in an alternative or non-conventional way to interpret the non-material phenomena and context by representing the visual actuality, event or process.
