Although there are many benefits to video ethnography, there are also important issues that arise from the use of videos. For instance, there are numerous ethical issues regarding the privacy of research participants or subjects. Schaeffer addresses the issues of voluntary consent and confidentiality of data. Voluntary consent is the control of involvement in the research lying firmly with the participant who needs complete knowledge of the research and its goals to exercise this control properly. There must also be mutual trust and respect between the researchers and the participants. Confidentiality implies the proper use of the gathered data as to maintain the highest degree of confidentiality possible while also maintaining the integrity of the research.
