Do I need consent for data sharing for textual and audio-visual material separately?
Not unless the data will be re-used and shared for different purposes e.g. if only transcripts will be archived and audio recordings not. In that case consent for data sharing is needed for transcripts, but not for audio. However, it is recommended for researchers to obtain consent that applies equally to all the materials resulting from the research. If data need to be anonymised, there may be a problem for sharing audio-visual data, as they are not easily anonymised and the damage to data integrity may be higher. In such cases separate consent for data sharing may need to be sought for textual and audio-visual data, whereby anonymised textual data can be shared whilst non-anonymised audio-visual may be preserved differently. See information on consent for using or sharing audio-visual material.
