Multimedia resources can be added and used in support of a questionnaire's layout or content, regardless of the interviewing modes for which it is designed. Nevertheless, due to the inherent technological differences specific to field types, you need to keep in mind the planned interviewing mode(s) when you insert multimedia resources into your questionnaires.
For more detail on inserting and managing multimedia resources, see the links below.
