W-VHS is a high definition analog video tape format created by JVC. The format was originally introduced in 1994 for use with Japan's Hi-Vision MUSE broadcasts and is no longer supported; the tapes are no longer manufactured and no players are currently produced for this format.

The recording medium of W-VHS is a ½-inch magnetic metallic tape stored in a cartridge the same size as VHS. The tape can be used to store 1080i or 480i analog signals (but not 480p or 720p).The video signal is recorded using a method called Time compression integration, which "records separated Component, Luminance and Color signals offset by time in alternating parts of video track". Because the color signals are recorded in component form instead of the color under method used by SVHS, standard definition image quality for W-VHS is typically much higher, due to the lack of noise caused by a chroma sub-carrier. Audio is stored in the VHS HiFi or S-VHS Digital Audio formats.[ref]

W-VHS could be used capture, record, and playback a Standard or High Definition signal via an analog Y/Pb/Pr component interface. W-VHS has been used for medical imaging, professional previewing and broadcasting.

Currently, it is very difficult to find either W-VHS vcr's or tapes. Since W-VHS tapes are harder to find many people have been using the similar Digital-S (D-9) tape. While D-9 are still not that easy to find they are more available than W-VHS tapes in certain regions. JVC Professional even recommends the use of them for W-VHS. The runtime between W-VHS and Digital-S are not the same. A Digital-S tape with a length of 64min is approx 105min when used with W-VHS.
