After you've determined the type of music you need, it's time to start analyzing potential songs. Consider the song's pacing. Songs with a steady rhythm are easy to change to suit your video style. Hoping to include your favorite, Top 40 hit? Popular, radio songs are usually structured in 4-5 parts and can be difficult to transition. Try to choose simple songs that are easy to loop. If you're looking for an instrumental song, be sure to find something that was recorded with real instruments. Songs made with digital samples can make your video feel unprofessional and out of date.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
