That may seem the same, but the secret's to make the interviewee relax and talk naturally, otherwise it sounds extraordinarily uncomfortable and fake.
These are just my viewpoints on the best strategies, but do not get the interviewee to look into the camera - they are not a presenter. If you really must be behind the camera, get a second person / mate to do the talking. I am sure many folks only know what they have read in many marriage periodical articles about wedding videography and photography. I have read the majority of these articles and they range between generic to sheer nonsense- particularly those articles with the check list of significant questions that should be asked a videographer.
Use any method to make them relax, and then introduce the questions you actually need to ask into the conversation.
