如何在 3SAX 中构建节拍同步动画

Build the beat-synced animation by setting the music BPM in the Music Group (MG), then arranging your camera, role, scene, and audio tracks to that beat in the Scheduler (AC) timeline. The tool syncs to your audio metadata; it does not create music.

在音乐组（MG）中设置音乐 BPM，然后在调度器（AC）时间轴上按该节拍排列相机、角色、场景和音频轨道，即可构建节拍同步动画。工具跟随你的音频元数据同步，不会自行创作音乐。

How to do it in 3SAX V3

在 3SAX V3 中怎么做

1. Open the Material Group (SG) panel. Upload your PNG parts, set Part ID / Parent ID, baseX / baseY, Anchor, Scale, Layer, and Z-perspective to build parts.

1. 打开素材组（SG）面板。上传 PNG 部件，设置 Part ID / Parent ID、baseX / baseY、锚点、缩放、图层、Z 透视，搭建父子树。

2. In the Music Group (MG) panel, upload your audio clip with Clip ID, Duration, and BPM, or enter a built-in NT note codec melody. Confirm auto-filled rests when prompted.

2. 在音乐组（MG）面板上传音频片段，填写 Clip ID / 时长 / BPM，或使用内置 NT 音符编解码输入旋律。提示时确认自动补齐的休止。

3. Open the Action Group (AG). Bind the material group, add action units with seq frame ranges, and use auto-suggest sequence to match each target part's states.

3. 打开动作组（AG）。绑定素材组，添加动作单元并设置 seq 帧范围，用自动建议序列匹配目标部件的状态。

4. Bind parts to skeleton joints in the Skeleton (BONE) panel so attached parts move together.

4. 在骨骼（BONE）面板把部件绑定到骨骼关节，让附着部件一起运动。

5. In the Scheduler (AC), place events on the 4-layer timeline: camera (L2), role tracks (L1, stacked), scene (L3), audio (L4). Align frame ranges to the BPM.

5. 在调度器（AC）的四层时间轴上放置事件：相机（L2）、角色轨道（L1，可叠加）、场景（L3）、音频（L4）。将帧范围对齐 BPM。

6. Create events in the Events (EVT) panel, trigger them from actions, and chain AC+MUS pairs in the scheduler.

6. 在事件（EVT）面板创建事件，从动作触发，并在调度器中串联 AC+MUS 对。

7. Open Canvas (CANVAS) to preview. Drag characters to fine-tune dx/dy, edit rot/scale; changes sync back to the codes.

7. 打开画布（CANVAS）预览。拖动角色微调 dx/dy，编辑旋转/缩放；改动会同步回编码。

8. Run whole-project validation, fix red hints and listed errors, confirm rest-fill, then render to MP4 (720x1280 or 1280x720) in RENDER.

8. 运行整项目校验，修正红色提示和错误列表，确认休止补齐，然后在 RENDER 渲染 MP4（720x1280 或 1280x720）。

What you CAN and CANNOT do

能做与不能做

CAN: save actions, music, schedules, and events to the LIBRARY server and reload them in one click.
CAN: drag one sentence into a one-shot clip to auto-arrange all panels.
CANNOT: compose music or generate songs. Wrong audio metadata or an unmatched seq triggers red hints or code rejection; a broken parent-child tree makes parts fly apart, and unresolved validation errors stop the render.

能：把动作、音乐、调度、事件保存到 LIBRARY 服务器，一键加载回对应面板。
能：输入一句话生成一次性短片，自动编排所有面板。
不能：创作音乐或生成歌曲。音频元数据错误或 seq 不匹配会触发红色提示或编码被拒；父子树断裂会让部件飞散，未解决的校验错误会阻止渲染。
