Sony Dynamic Digital Sound

Background :  is a cinema sound system developed by Sony that was first introduced in 1993 with Last Action Hero. Unlike its two main competitors (Dolby Digital and DTS), there was no home media variant of this sound system. As a result, adoption of this sound system was limited and relatively few titles (especially independent films) took advantage of the system's full capabilities (up to 8 channels).

1st Logo (June 18, 1993-1999)
Nickname : "Breaking the Digital Sound Barrier", "The Pyramid", "Supernova"

Logo : A couple of white shooting stars shoot across the screen, then go into a large, zooming-out, blue supernova. A flash occurs, leaving behind several yellow stars shooting at the screen, and a large sparkle in the center and several lens-flare-like circles appearing in the middle of the screen. Then, a glowing tilted horizon with red and black colors underneath it fades in as a large yellow pyramid swings into the center, and the large stylized text "SDDS" zooms out onto the triangle, leaving behind several blue dust as it does so. "" appears below "SDDS", and all the text begins to glow. The slogan "BREAKING THE DIGITAL SOUND BARRIER" fades in below the whole thing as the triangle zooms in. When the triangle disappears completely, the horizon turns into dust scatters all over the screen before fading out with the slogan.

Trivia : The whole logo was done on SGI workstations. Modeling and animation was done by Elizabeth Keith using Alias/Wavefront PowerAnimator. Compositing and rainbow effects were done using Alias/Wavefront Composer. Particle effects were made using custom software.

FX/SFX : Very great CGI animation for 1993. This was done by Sony Pictures Imageworks.

Variant : In German, it says "Durchbrechen der Digitalen Schallmauer".

Music/Sounds : A series of whooshes and descending synths are heard all around the speakers playing the logo (whether they be on your computer, in a theater, or elsewhere). Then,an explosion occurs, alongside a deep synth note. It then turns into a bell note, then an ascending trumpet and an orchestral hit.

Availability : Extinct. It appeared on theater chains using the system during the time period.

Editor's Note : None.

2nd Logo (1999-2014)
Logo : We start out on a black screen for a few seconds before the camera moves, revealing a sea-blue set of shapes with fish swimming in it. The camera turns away, then goes under a crack revealing an entire undersea environment with rocks, fish and reefs. After a few seconds of footage in the sea, the camera then rises out of the ocean and heads straight into a series of trees into a jungle. The camera pans all through the trees in there before transitioning into a different shot of the jungle, where birds fly out from the trees. The scene then directly fades into old stock footage of a volcano. When the camera swings directly into the volcano, the inner part of the volcano becomes CGI and we zoom deeper into it before the text "SDDS", in the same font as before, appears in yellow and shoots at the camera. The environment disappears and becomes nothing but smoke. The Sony logo appears briefly and faintly in yellow, before the smoke clears out and the SDDS logo appears at the left of the screen, with "Sony Dynamic Digital Sound" next to it.

Variants : All of the sequences in this logo have spun-off into their own trailers. The "Volcano" trailer follows the same ending as the main version, while the "Jungle" and "Undersea" trailers end by fading into the same ending animation, albeit now tinted blue.

FX/SFX : It's all live-action except for the subtle scene transitions, and the inner part of the volcano and ending. All of the scenes are well-shot with perfect CGI animation.

Music/Sounds : A dark fanfare that starts off whimsically, before gaining jungle drums and becoming more louder during the volcano sequence. The fanfare grows more and more dramatic as the SDDS logo shoots out, before turning silent and drawing back in some drums. Three string notes are heard before an orchestral hit occurs.

Availability : Might still be seen in theaters using SDDS.

Editor's Note : None.
