时间轴基础

使用时间轴来排列片段、设置时长并添加声音。当您准备好将画布媒体编辑成影片时，从这里开始。

开始之前

选择您想要使用的片段和影片的宽高比。两个片段就足够练习剪辑了。

打开时间轴

您可以在两种布局中打开时间轴：

  • The Video Editor tab at the top of the canvas, next to Story, Canvas, and 3D Stage. This is the full editor: Assets on the left, the preview in the middle, Properties on the right. An empty timeline says "Turn your shots into a video" and offers Let Agent build my timeline, or you drag a shot in from the Assets panel.
  • The Video Editor button on the left toolbar of the canvas. This keeps you on the canvas: it opens a floating Player panel and the same timeline as a strip along the bottom of the canvas, with the same toolbar.

打开了播放器面板和时间轴条的画布。下方是视频编辑器标签页。

时间轴上有什么

  • Panels. Assets on the left, with tabs ASSETS, EFFECTS, TRANSITIONS, MOTIONS, and SFX; the preview in the middle; Properties on the right for the selected clip. Each panel can be hidden or resized.
  • Tracks. Video and image clips on the Main track, where the main-track magnet helps close gaps when you reorder clips; audio on the Music track; text clips on their own track.
  • Playhead. The vertical line that marks the current frame. Drag it to scrub; hold Shift while scrubbing to snap to clip edges.
  • Toolbar. Left to right: keyboard shortcuts (?), zoom, the timeline aspect ratio, play with the timecode, fullscreen, Select tool (V), Razor tool (C), Delete left of playhead (Q), Split (S), Delete right of playhead (W), the main-track magnet, snapping (N), Generate captions, Add text (T), and Export.
  • Magnet and snapping. The main-track magnet closes gaps when you reorder clips on that track. Other tracks can keep gaps, and adding a clip at a chosen time can leave one. Check the sequence starts at zero. Snapping aligns clips with nearby edges; it does not close gaps. Press N to toggle snapping or hold Alt to pause it while dragging.
  • Properties. With a clip selected, the right panel opens with PROPERTIES, COLOR, and EFFECTS tabs. Properties holds the clip's layout (scale, rotation, opacity, crop, position), its sound (volume, fade in and out, Generate captions, Detach Audio), its playback (speed, Reverse, fade in and out), and its dimensions. See Clip properties, Effects and color, and Keyframes. Transitions live in the TRANSITIONS tab of the left panel.

观看当前影片

按空格键或点击播放从播放头位置开始观看。Home返回开头。左/右箭头移动一帧；按住Shift移动五帧。上/下箭头跳转到上一个或下一个剪辑点。

在编辑前观看完整序列。检查镜头顺序和时长以及单个片段。

如果出现问题

我找不到时间轴。打开画布顶部的视频编辑器标签页，或左侧工具栏上的视频编辑器按钮。

时间轴是空的。上面还没有任何内容。在资产面板中的镜头上使用添加到时间轴，拖入一个镜头，或点击让智能体构建我的时间轴；请参阅添加和重新排序片段。

工具显示为灰色。时间轴在生成字幕时会锁定。等待字幕生成完成。

我看到时间轴但没有画面。将播放头移动到片段上。时间轴的空白部分不显示任何内容。
