Video Huset
From the Audiovisual Identity Database, the motion graphics museum
(Early 80's)
Visuals: On a hot purple background, there is a white object, resembling the Cryllic letter "ф" with the left hole briefly filling in with white, kinda like a blink. The object then morphs into a mirrored "h", and then to the connected letters "vh" while a TV tube-shaped border grows around it. It then cuts to the top left corner as the text "VIDEO-HUSET A.S" wipes in below in white.
Technique: The object blinking and morphing, the text wiping.
Audio: A low-volume bell when it "blinks", followed by a ascending synth warble.
Availability: Can be found on videos from the era, Such as Poco... Little Dog Lost.
