How do I sync an animation to a BPM value?

如何让动画与 BPM 值同步
Last updated: 2026-10-21

Set the BPM on your audio clip in the Music Group panel, then align your action frame ranges in the Action Group and place short action events on the scheduler audio layer so each beat lands on a frame boundary.

在音乐组(MG)面板为音频剪辑设置 BPM,然后在动作组(AG)对齐动作帧区间,并把短动作事件放到调度器音频层的节拍边界上。

How to do it in 3SAX V3

在 3SAX V3 中的操作步骤

1. Open MG (Music). Upload your audio clip and set Clip ID, Duration and BPM.

1. 打开 MG(Music),上传音频剪辑,设置 Clip ID、时长和 BPM。

2. Or use the built-in NT note codec: enter tone + melody; confirm the auto-filled rests.

2. 或使用内置 NT 音符编解码:输入音色+旋律,确认自动补齐的休止。

3. Open AG (Action). Bind the material group and add action units with seq frame ranges (e.g. 01:0-5) sized to one beat.

3. 打开 AG(Action),绑定素材组,添加动作单元,按一拍长度填写 seq 帧区间(如 01:0-5)。

4. Use auto-suggest sequence so each seq matches the target part's available states.

4. 使用“自动建议序列”,让 seq 匹配目标部件的可用状态。

5. Open AC (Scheduler). On the L4 audio layer place the clip; on L1/L2/L3 place action, camera and scene events on beat boundaries.

5. 打开 AC(Scheduler),在 L4 音频层放置剪辑;在 L1/L2/L3 把动作、镜头、场景事件放在节拍边界。

6. Link triggers in EVT and chain AC+MUS pairs so music and motion start together.

6. 在 EVT 中设置触发事件,串联 AC+MUS 配对,让音乐与动作同时开始。

7. Open CANVAS to drag the character, adjust dx/dy, rot and scale; changes sync back into the codes.

7. 打开 CANVAS 拖动角色,调整 dx/dy、旋转和缩放,改动会同步回代码。

8. Run whole-project validation, fix the listed errors, then RENDER to MP4.

8. 执行整项目校验,按错误列表修正,然后 RENDER 导出 MP4。

What you CAN and CANNOT do

可以做什么,不能做什么

  • CAN: set BPM per clip, reuse music from LIBRARY, extend finished clips by editing codes.
  • CANNOT: expect the tool to compose music, auto-detect BPM from a file, or auto-quantize your frames.
  • Wrong inputs show red hints; bad seq ranges or unconfirmed rests block the render, and mismatched layers make parts fly apart.
  • 可以:为每个剪辑设置 BPM,从 LIBRARY 复用音乐,编辑代码扩展已完成片段。
  • 不能:让工具自己作曲、自动从文件识别 BPM,或自动量化你的帧。
  • 输入错误会显示红色提示;seq 区间错误或休止未确认会阻止渲染,层不匹配会导致部件错位飞散。
