2 minute max. Most people have about a 1 minute attention span on Real Estate videos. 80% should be of the house itself and then the other 20% could be of the view from the house and surrounding areas. Use fast motion when moving around the landscape. Example. Start close on the house and fly backwards facing house until you are about 200 feet out. The whole clip should be about 3 seconds.
