DVD-Video is a consumer video format used to store digital video on DVD discs, and as of 2003 is the dominant consumer video format in Asia, North America,Europe, and Australia. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e. g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typically, the data rate for DVD movies ranges from 3 Mbit/s to 9.5 Mbit/s, and the bit rate is usually adaptive. It was first available in November 1996 in Japan.

The DVD-Video specification was created by DVD Forum and can be obtained from DVD Format/Logo Licensing Corporation for a fee of $5,000. The specification is not publicly available and every subscriber must sign a non-disclosure agreement. Certain information in the DVD Book is proprietary and confidential.

To record moving pictures, DVD-Video uses either H.262/MPEG-2 Part 2 compression at up to 9.8 Mbit/s (9,800 kbit/s) or MPEG-1 Part 2 compression at up to 1.856 Mbit/s (1,856 kbit/s). DVD-Video supports video with a bit depth of 8-bits per color YCbCr with 4 : 2 : 0 chroma subsampling.

The following formats are allowed for H.262/MPEG-2 Part 2 video:
