The Digital8 Video Format (D8)
The Digital8 format, also known as D8, was introduced in the late 1990s and replaced Sony's analog Video8 and Hi8 formats.
Digital8 is a transition format which is a compromise between the digital MiniDV format and Sony's existing 8mm formats. Digital8 uses the same digital codec as MiniDV but in the traditional 8mm cassette tape. Digital8 is backwards-compatible with previous 8mm formats which is an advantage for existing Sony users.
Digital8 is not a strong player in the digital video market — MiniDV is dominant.
