S.T. Grand Corporation

Background
Unknown.

1st Logo (1980s-1990s)
Visuals: Footage of 3D space planets & stars moving further from view (in order: Earth, Sun, Moon, Jupiter and Saturn) on a black background is shown. After a few seconds, a TV tube like rectangle with a yellow border, with the three colors, and  inside and the "ST" wordmark - in a vintage-styled font - zooms at the center. White Thai text then appears above.

Technique: Besides the background footage, most of the logo is very simple animation.

Audio: Excerpt from the "Sunrise" movement of Thus Spoke Zarathustra.

Availability: Might appear on earlier VHS releases.

2nd Logo (1989-1999)
Visuals: Stars are shown emerging at the center of a black background. The ST logo from before, now in 3D and with the text textured in golden, flips back and settles near the top side. The logo is placed in a slight top-looking perspective. The words "S.T. VIDEO" in emerge below the logo with a widening effect.

Variant: In late 1990s releases, the white URL fades in above the name.

Technique: Choppy CGI (notice how the 1st half of the logo is in a slower framerate than the 2nd).

Audio: A jet-like noise and a thud is heard.

Availability: Seen on most 1990s S.T. distributed releases.

3rd Logo (1999-2002)
Visuals: A starry background fades in. The 3D S.T. logo is shown flashing at the left side, as it pans into a close-up and then rotates & faces into the center. The letters of "VIDEO" appear and move back placing themselves in order. The URL, also in yellow appears from below as it stretches out.

Variant: The logo has been reworked in 2002, with additional animation like having a lens flare emerge the logo & glowing effects. The logo now faces normally rather than at the top and there is no "VIDEO" subtitle.

Technique: The 3D CGI, while much better than before, still has some apparent flaws.

Audio: A majestic brass fanfare. The later variant has no sound.

Availability: Unknown

Technique: Unknown

Audio: A whimsical piece with many metallic sounds and whooshes during the animation, then a loud engine sound and an electric zap / hum is heard.
