In qualitative research, it is crucial for the researcher to ask whether, in light of his or her object and goals, it would be more appropriate to conduct systematic observations, to produce a handwritten or recorded field journal, to conduct interviews (structured or not), to photograph, to videotape and so on. The proper response to these questions will determine, to some extent, the quality, scope, adequacy and feasibility of the empirical data gathered.
One should ask, then, under what circumstances video recording arises as a necessary resource to conduct qualitative empirical research.
After recording, all the videotaped material must be identified, cataloged and stored properly right after it is produced in order to ensure the access to each item and its analysis.
