How Do I Time a Laser Dance Animation to the Beat?
Open ILDA Files, set CATEGORY to Characters, and search for Gangnam Style or Clap and Sweep. Open a cue in ILDA Viewer. To check the whole routine, start at 20 fps with BEAT SYNC → Off - Loop Freely. If you want a short repeat over music, set MUSIC BPM and choose how many beats to play before the animation goes back to its first frame.
Gangnam Style in the Cinema software preview. Watch the crossed wrists and galloping steps as the camera moves.
Why does Clap and Sweep start over so soon?
- Open Clap and Sweep in ILDA Viewer and expand PLAYBACK CONTROLS.
- Set FPS to 20 fps, MUSIC BPM to 120, and BEAT SYNC to 1 Bar (Very Slow). One bar lasts two seconds. The Viewer repeats the first 40 frames of the 137-frame file.
- Set BEAT SYNC to Off - Loop Freely and watch how the arm movement develops after the opening. The full file lasts about 6.85 seconds at that frame rate.
How do I choose a loop for my track?
Use the Looping frame count in PLAYBACK CONTROLS to see exactly how much choreography fits. At 120 BPM and 20 fps, two bars hold 80 frames. That gives you a longer excerpt of Clap and Sweep. The full Gangnam Style cue has 247 frames and takes just over 12 seconds at 20 fps.
For a short loop, watch the jump from the last pose back to the first. A wrap during a gesture can look abrupt even when the duration is right. If you want the complete choreography to land on a musical phrase, prepare an excerpt with matching start and end poses or use a cue authored for that phrase length. The general ILDA timing guide shows how BPM and FPS affect the frame count.
MUSIC BPM sets a repeat interval. Start playback on your downbeat when comparing it with a track. The Viewer does not detect that downbeat for you. Set the playback timing again in the player that will use the exported ILDA file.
Can I try these dances in OSC-1?
Yes. In Creator → Import Shapes → 3D Import, choose CLAP AND SWEEP under Mannequin renders (2D) and click PLAY RENDER to draw the recorded outline. For an animatable GANGNAM STYLE clip, load FEMALE FIGURE and choose it under DANCE in the clip picker. The OSC-1 3D guide covers both workflows.
