Video High Density

Background
Video High Density (VHD) was a Japanese videodisc format, not unlike the CED or Laserdisc. It was marketed mainly by JVC or Victor Company of Japan, and in a lot of ways it was similar to a CED. It was released in 1983 and players were made until around 1987. Discs continued to be made until the early 1990s.

1st Logo (1983-1986?)
Logo: On a light grey/white background, some blocky text slowly rotate, it turns out to be the VHD logo, which consists of blocky letters with rounded corners, the logo constantly changes colors and the outline shines throughout, After a while, the logo rotates back and fades out.

Variant: After the VHD logo fades out, another logo of a publisher/company might appear, such as Pack-In-Video, or Victor (with the "His Master's Voice" trademark on the left).

Technique: Just the logo shining, changing colors and rotating, which is a bit simple, but alright.

Music/Sounds: A choir for the first half, for the second half, it turns into a flute with some guitar strums, electronic sounds play throughout.

Availability: Extremely rare. Seen on releases from launch until some time in the late 80s.

2nd Logo (1986?-Early 1990s)
Logo: On a light and dark grey tile floor, a shadow of the words "VIDEO", eventually, the floor zooms out as we see the word "VIDEO" in gold. A few seconds later, the text "DISC" in the same style and color as "VIDEO" zooms out. As they finish zooming out, the tile floor fades to a dark/light grey gradient. As it finishes the transition, the VHD logo from before fades in, this time in white.

Technique: The moving text and the floor, all CGI.

Music/Sounds: A cheerful orchestral theme.

Availability: Like before, it's extremely rare. Seen on later releases on the format.
