Knockout Video Film Distributors

(1981)
Logo: On a black background, we see these words in a computerized font:

KNOCKOUT VIDEO PRESENTS

Later Variant: Later on, the black background would be replaced with a rainbow background, equal signs would be added above and below the logo, and "PRESENTS" would be replaced with "PRESENTATION".

Technique: None.

Music/Sounds: None.

Availability: Seen on many pre-cert releases from the company, as many of them are considered as video nasties due to their very obscene films they distributed on their videocassettes such as Flesh Eaters.
