Agree with above comments. First learn the art of photography and videography, composition, technical skills (exposure, white balance, depth of field) & get yr drone qualifications & drone insurance. There is no such thing as a real estate template, it completely depends on the property. The general rule for video is keep it less than 3 mins, no shakes, bright exposure & licensed music that fits the property. A ten million lakeside estate gets quite a different approach than a 200k downtown condo.
