The most important thing to do is to create Bins for every different type of file you are using. Bins are the folders in the Browser that you can place different types of files. Each project uses a different type of organizational system, but it is best to divide different types of footage you have shot into different Bins based of relevance and production dates. If you are using photos, stock footage, music, or sound effects, they should all have their own labeled bins. Once you begin editing you will be chopping your video clips into smaller subclips for creating sequences. Give each sequence its own Bin and then put each tiny subclip into its respective Bin so you know exactly where each subclip is being used. Likewise, make sure every video and audio clip is properly labeled and numbered for easy access.
