MiniDVD
MiniDVD or 8 cm DVD (also "3 inch DVD") is a DVD disc with a reduced diameter of . It has been most commonly used in camcorders due to its compact size. The most common MiniDVDs are single layered and hold 1.4 GB of data, but there are variants that can offer up to 5.2 GB of storage space, through a combination of dual layers and dual sides. 8 cm DVDs were originally used for music videos and as such became known as DVD single, similarly to how 8 cm optical discs were previously used for music singles on compact discs (i.e. CD single and miniCD). However the MiniDVD format has been mostly used as recordable discs in DVD-based camcorders during the 2000s; a single layer disc can record up to 30 minutes of standard definition video. A number of movies and TV shows have also been released on the format in the mid-2000s, usually targeting children using low-cost small players.

CDVD
cDVD ("Compact DVD") discs, also known as mini-DVD discs (not to be confused with 8 cm DVDs), are regular data CDs that contain MPEG-2 or MPEG-1 video structured in accordance with the DVD-Video specifications (such as a VIDEO_TS directory containing properly authored IFO/BUP and VOB files, typically on a Mode 1 data track formatted with the UDF 1.02 filesystem). In the early 2000s, CD recorders and their discs were significantly more available and inexpensive than DVD-R equipment, promoting demand for miniDVD; however, DVD-Video content on other media does not conform to specifications. When using full resolution video and a single AC-3 soundtrack at typical medium quality encoding settings, a 74 minute (650 MB) CD-R can hold approximately 10 to 15 minutes of material, increasing to about 45 minutes at rather lower quality. By using non-standard resolutions, long GOPs, more B-frames, and high-compression quantization matrices, it is possible to store up to 2 hours of video ...

Universal Media Disc
The Universal Media Disc (UMD) is a discontinued optical disc medium developed by Sony for use on its PlayStation Portable handheld gaming and multimedia platform. It can hold up to 1.8 gigabytes of data and is capable of storing video games, feature-length films, and music. UMD is the trademark of Sony Computer Entertainment for their optical disk cartridge (ODC). Video storage format While the primary application for UMD discs is as a storage medium for PSP games, the format is also used for the storage of motion pictures and, to a lesser degree, television shows for playback on the PSP. The video is encoded in the H.264/MPEG-4 AVC format, with the audio in ATRAC3plus or PCM. Video stored on UMD is typically encoded in 720×480 resolution, but is scaled down when displayed on the PSP. To date, there are around 1,500 films released on UMD (around 1,000 are common for all regions and around 500 are region exclusives). The American punk rock band The Offspring released th ...
