BeatDance

BeatDance is an original creation tool for turning your own audio into beat-synced 3D music ball videos.

Import an MIDI, MP3 or M4A file from your device — or pick a video and let the app extract its audio track — and the app analyzes the rhythm and automatically builds a 3D scene in seconds. During preview, the ball bounces, rolls, and interacts with generated structures such as boards, rails, pipes, and bells exactly on the beat, so the motion and the music stay visually locked together.

Before generating, you can pick the part of the song you want: drag the two handles on the waveform to select a section, or use auto-trim to remove the silence at the start and end. The 3D scene and the exported video use only that section.

Unlike tools that require manual 3D editing, BeatDance focuses on fast automatic scene generation. After importing audio, users can directly get a playable scene without placing platforms or adjusting timing by hand.

BeatDance also includes features designed for visually distinctive results:
- Seamless loop playback and export, with loop-aware scene construction for continuous replay
- Curved World styles that bend the whole scene for a more unique visual look
- A first-person view that places you inside the scene for a more immersive way to watch the ball
- A "Props" panel for choosing which charms (star, heart, bell) and fixtures (bulb, torch, flower) may appear in a scene
- A "Color" panel with several picture styles and an adjustable vignette
- A customizable default background with adjustable brightness and reflection strength
- Automatic preset cycling that switches between saved presets at the interval you set
- Multiple ball materials, trail effects, impact effects, extra effects, and wall textures
- Adjustable lighting: brightness, color warmth, environment light direction, and environment light strength
- Audio trimming so you can build a scene from just the section you want
- Video export for saving the generated result to your device
- A relatively lightweight installation footprint for a 3D scene creation workflow

BeatDance is built for creators who want to quickly turn music into stylized 3D rhythm visuals on mobile.
