HDV: High definition digital video format commonly used by cameras to record to DV cassette tape. This format was developed by JVC but is commonly found in Canon and Sony cameras as well. HDV is based primarily on lossy MPEG-2 compression which is based on older technology and is not as efficient as H.264/AVC/MPEG-4 compression. HDV formats include HDV 720p, HDV 1080i, and HDV 1080p. the DV cassettes are not recommended as a preservation format but prove to be an efficient and effective capture format. However, as the industry begins to move away from tape-based recording, this format is becoming less common. [ Video Glossary ]
