Though some would disagree, I do not believe that we must produce Hollywood quality video. Nor do I believe that it is necessary to hire anyone. The state of technology makes it easy to produce a very acceptable video of a home tour. You can either use still photos and Windows Movie Maker, or you can use a camera like The Flip and do moving video. Either way, a nice tour can be produced. I prefer stills for home tours, using a high end Canon digital and wide angle lens. However, for local color and nature, I like The Flip.
This is about background music. In either case, some videos do not need any voice on the soundtrack. That's particularly true if you have a Texas accent like mine. I prefer to do text cues of the home's features, rather than talking. In this case, and in the case of nature or outdoor videos, I like a subtle music track at low volume.
Wanting to be legal, I found several online sources to purchase royalty free music. What does royalty free mean? The music is not free, but to use it after you've purchased it, you do not need to pay any royalties to the artist. So, you buy it once, and you can use it over and over in your videos and on your websites and blogs.
The one I like the best is AudioMicro.com. It allows me to download a single song or an album, and the downloads are easy to accomplish in .wav or .mp3 formats. I can then just drag that music track into a video in The Flip software or in Windows Movie Maker. At around $1 per minute or less for the music, it is an affordable solution for real estate video music.
