Constellations: the night sky to your song

Choose one with the Constellation control on the template page, in Classic, in Studio's layer settings, in the Timeline's clip look, in the Layers tool, in Generate visualizer or on the Layer assets page. Type to search: a name, its IAU abbreviation (UMa), another of its names (the Plough, the Seven Sisters, Scorpio) or what its name means (the Hunter). The picker groups them as the sky is usually taught:

• Famous star patterns (the shapes people know by name, inside one constellation or across several): Big Dipper, Cassiopeia's W, Circlet of Pisces, False Cross, Great Diamond, Great Square of Pegasus, Little Dipper, Northern Cross, Orion's Belt, Orion's Sword, Pleiades, Summer Triangle, The Fishhook, The Keystone, The Kite, The Sickle, The Teapot, The Water Jar, Winter Hexagon and Winter Triangle.
• The zodiac (the twelve constellations the sun passes through in a year): Aquarius, Aries, Cancer, Capricornus, Gemini, Leo, Libra, Pisces, Sagittarius, Scorpius, Taurus and Virgo.
• Ursa Major family (the great bear and the northern figures round the pole): Boötes, Camelopardalis, Canes Venatici, Coma Berenices, Corona Borealis, Draco, Leo Minor, Lynx, Ursa Major and Ursa Minor.
• Perseus family (the hero, the princess he saved, her royal parents and the sea monster): Andromeda, Auriga, Cassiopeia, Cepheus, Cetus, Lacerta, Pegasus, Perseus and Triangulum.
• Hercules family (the great hero and the creatures, crowns and tools along the summer sky): Aquila, Ara, Centaurus, Corona Australis, Corvus, Crater, Crux, Cygnus, Hercules, Hydra, Lupus, Lyra, Ophiuchus, Sagitta, Scutum, Serpens, Sextans, Triangulum Australe and Vulpecula.
• Orion family (the hunter, his two dogs, the hare and the unicorn of the winter sky): Canis Major, Canis Minor, Lepus, Monoceros and Orion.
• Heavenly Waters (the river, the ship argo and the creatures of the water): Carina, Columba, Delphinus, Equuleus, Eridanus, Piscis Austrinus, Puppis, Pyxis and Vela.
• Bayer family (southern birds and creatures first charted by sailors in the 1590s): Apus, Chamaeleon, Dorado, Grus, Hydrus, Indus, Musca, Pavo, Phoenix, Tucana and Volans.
• La Caille family (southern instruments and tools named in the 1750s): Antlia, Caelum, Circinus, Fornax, Horologium, Mensa, Microscopium, Norma, Octans, Pictor, Reticulum, Sculptor and Telescopium.

• Every constellation's own page

Every star is where it is in the sky, as bright as it looks and in its own colour: places, magnitudes and colours from the Yale Bright Star Catalogue, a public domain star catalogue, and each figure's lines as the IAU charts draw them, through d3-celestial (both credited on the licences page). Two stars the eye sees as one, such as Alpha Centauri, are drawn as one. The sky round the figure is the real one too, to the faintest stars you can see from a dark place.

Each star answers its own part of the song by its colour: the red and orange stars the bass, the white and gold the mids, the blue the highs, so a bass line brings up Betelgeuse while the hats sparkle Rigel.

The famous star patterns are Big Dipper, Little Dipper, Orion's Belt, Orion's Sword, Summer Triangle, Winter Triangle, Winter Hexagon, The Teapot, Great Square of Pegasus, Cassiopeia's W, Northern Cross, The Sickle, The Keystone, The Kite, Great Diamond, False Cross, Circlet of Pisces, The Fishhook, The Water Jar and Pleiades.

• Licences

Night Sky: The constellation in a clear night sky over the hills: its lines draw themselves one on every beat, its real stars twinkle with the part of the song their colour answers, the Milky Way glows and a shooting star crosses on the big moments. Star Lore: The figure drawn in lines of light inside a glowing nebula, the way the old star atlases drew their heroes and beasts: comets run along its lines on the beat and its aura breathes with the bass. Planetarium Dome: The sky on a planetarium dome over rows of seats: the dome sways slowly as the projector turns the stars, its grid glows, the lights round its rim answer the spectrum and the figure lights a line on every beat. Telescope Eyepiece: Through the eyepiece: the view hops from star to star along the figure, one a bar, with the crosshairs on each and its name, brightness and place in the sky read out beside it. Bright stars throw diffraction spikes and the focus breathes with the bass. Star Chart: A printed star chart: the real stars inked by brightness on a grid of right ascension and declination, their Greek letters beside them, and a pen tracing the figure a line on every beat, the stars it reaches ringing as it goes. Star Sign Card: A card for a star sign or a night to remember: the figure in gold inside an art deco frame, its name in capitals and your own line under it, sparkles round the frame on the beat and a sheen of foil across it on the big moments.

Every control is in the editors, labelled, and SW Agent can set each one by its name (for example "switch the constellation to the Southern Cross", "set the line tracing to a line every bar" or "set the constellation scene to Star Chart"). The look's own settings:

• Primary color: Primary color used by the engine palette.
• Secondary color: Secondary color used by the engine palette.
• Background: Background used by the engine palette.
• Opacity: Visualizer opacity.
• Sensitivity: Bounded overall audio response.
• Spectrum range: How much of the 40 Hz to 14 kHz range the visual spans, from the bass up. Lower it to give the bass and mids more of the bars.
• Frequency scale: How the bars are spread across the frequencies. Log spreads them by octave, mel by how pitch is heard, and linear by hertz, which gives most bars to the highs.
• Auto-level: Lifts every part of the spectrum to its own recent range, so quiet highs move as much as loud bass. A note held for several seconds settles lower as it adapts. 0 shows the raw spectrum.
• Primary audio source: Primary audio source.
• Frequency focus: Which part of the spectrum drives this visual; while no explicit audio source is set, the motion envelope follows this selection.
• Burst intensity: Glow and trail swell on sharp hits; 0 keeps bursts off.
• Ambient bed: Prominence of the standing background layer behind the beat-born elements.
• Wake length: How far motion trails stretch behind beat-born travelers; 0 removes the wake.
• Audio contribution: Maximum contribution from the primary audio route.
• Audio dynamics: How much of the band's movement reaches the visual. 1 = full dynamics; 0 holds it at a steady level for a calmer, more constant look.
• Audio attack: Envelope attack in milliseconds.
• Audio release: Envelope release in milliseconds.
• Geometry scale: Geometry scale.
• Motion direction: Rotate the animated visual pass to face this direction; the general background stays fixed.
• Speed: Time-based motion; default major cycle is 6–12 seconds.
• Color mode: Duo palette, primary→secondary gradient, or full rainbow sweep.
• Glow: Glow.
• Global glow: Shared emissive strength across the frame.
• Pulse intensity: Beat pulse scale for spawn, size, and shake.
• Beat response: How hard every engine hits on each detected beat.
• Beat smoothing: How long each beat hit rings out before it settles.
• Beat attack: Seconds for a hit to swell to full. 0 snaps instantly.
• Beat release: Seconds for a hit to fade, overriding Beat smoothing. 0 follows it.
• Beat shake: Frame kick strength on each beat.
• Motion echo: Motion echo.
• Blur: Blur.
• Chromatic aberration: Chromatic aberration.
• Beat sync all: Route beat energy into spawn, shake, pulse, speed, and scale.
• Symmetry and tiling: Reshape the whole picture: mirror it, fold it into a kaleidoscope, or tile it (the plane groups p1, p2, p4m and p6m).
• Kaleidoscope folds: How many mirrored copies go round the kaleidoscope.
• Symmetry angle: Turns the mirror line, or the kaleidoscope, in degrees.
• Kaleidoscope spin: How fast the kaleidoscope turns, in turns per bar of the song (0.25 is once a phrase).
• Tile size: Each tile's size as a share of the frame.
• Tile gap: The gap between tiles, as a share of a tile; it shows the background colour.
• Warp: Bend the whole picture: a twist, a bulge, waves or ripples that move once a bar, a polar unroll, or a fisheye lens.
• Warp amount: How strong the warp is.
• Warp centre: Where the warp is centred in the frame.
• Constellation: Which constellation or star pattern the look shows: any of the 88 constellations, or a famous pattern such as the Big Dipper, Orion's Belt or the Pleiades. Its stars are the real ones, where they are in the sky.
• Line tracing: How the figure's lines appear: one line drawn on every beat or every bar, the whole figure held a while and then drawn again, or the figure always whole.
• Star names: Show the names of the figure's brightest stars (Betelgeuse, Rigel) beside them.
• Twinkle: How much the stars twinkle. Each star answers its own part of the song by its colour: the red stars the bass, the white and gold the mids, the blue the highs.
• Background stars: How many of the real stars round the figure are shown, brightest first.
• Sky motion: How much the sky drifts and turns, the dome sways and the eyepiece moves from star to star.
• Greeting: Your own line on the card, such as "Happy birthday, Leo" (the card says "Written in the stars" without one), and under the title in the other looks.
• Loop length: Seconds before the sky's drift, the twinkle and the haze repeat exactly, so a clip loops without a seam.
• Title and artist: Show or hide the song title and artist this visualizer draws.

Ask for one by name ("make a constellations visualizer with Orion", "make a Big Dipper visualizer", "the Pleiades for TikTok") and SW Agent builds the project with that figure already chosen. A name the sky shares with an animal or a creature of myth (the Lion, the Phoenix) is the constellation when you say so: "make a Phoenix constellation visualizer". In an open project it puts the figure on the look, or changes any of its settings. Assistants connected over MCP can open the editors on any figure too.
