If you want to create a DV project:

• Get familiar with DV terminology by learning about digital video, D1, DV, and various pixel aspect ratio footage (see About D1, DV, and various pixel aspect ratio footage) and using square-pixel footage for output to D1 or DV NTSC (see Using square-pixel footage for output to D1 or DV NTSC).
• Use output templates for export by making a movie (see Making (rendering) a movie), changing output module settings (see Changing output module settings), and creating and using output module templates (see Creating and using output module templates).
• Choose correct composition size by understanding basic composition settings (see Understanding basic composition settings), setting frame size (see Setting frame size)and pixel aspect ratio (see Setting pixel aspect ratio for compositions), and setting frame rate and resolution (see Setting frame rate).
• View non-square pixels on a square monitor by seeing About D1, DV, and various pixel aspect ratio footage.
• Create graphics in other applications to use in your DV project by seeing the Using square-pixel footage for output to D1 or DV NTSC.
