Create a Custom Visualizer from a Still or Video

Background Motion Studio creates a visualizer scene from scratch or from your own still or video. It layers the same V3 engine drawings used by Sonic Weaver over your chosen media, and keeps the scene editable before you continue in Classic or Studio.

Choose a starting point

1. Open Background Motion Studio. Press Start blank V3 visualizer, choose a bundled background, or import an image (PNG, JPEG, WebP or GIF) or an MP4/WebM video. You can also generate a still from a built-in shader recipe.
2. For an image or video, press Build custom visualizer layers. The tool adds the selected V3 drawing and editable particle/glow layers. On still images it may also suggest a foreground from edge colors; refine it with the manual cutout tool. This analysis is local and does not identify semantic subjects. Video is treated as one clip layer, not automatically split into moving subjects.
3. In Background layers, select each layer to adjust its visibility, order, opacity, blend mode, position, scale, rotation, brightness, motion and fit. V3 layers expose the selected engine's mode and declared controls; drawing layers expose their amount and colour.
4. Open Custom recipe editor to set up and save your own particle, wave or glow drawing recipe. To save an engine recipe, select a V3 layer and choose Save selected V3 layer. You can add, edit, update or delete recipes; their cards show the creation date and use count. Recipe settings stay in this browser and can be managed from the Background Motion workspace in either editor.

Preview with your music

• Attach a local song in Beat-reactive audio. The shared analyzer supplies spectrum, onset and beat data to the V3 drawing; without a song, the built-in beat clock drives the preview. The source track stays in your browser.
• Choose Animated visualizer, press Preview, and scrub the preview position to inspect a frame. The source video is muted; the optional song is the visualizer soundtrack.
• Set loop duration, frame rate and output aspect/size. Export a PNG still or a 3–30 second WebM loop. Downloaded loops and stills are listed in Background & layer assets when local browser storage is available.

Save or continue editing

Save the complete layer stack as a local visualizer template, save one layer, or download the scene JSON. Source images and videos are kept in IndexedDB on this browser and are not inside the JSON; the files do not sync across devices or profiles. A rendered PNG or WebM can be returned to Classic or Studio for further editing and audio/timeline work. The scene recipe itself currently stays in Background Motion Studio.
