简介

Blender is a versatile software used for modeling, sculpting, 2D drawing, animation, and video editing. Most of the work is done in so-called editors: tools for viewing and modifying your work through a specific part of Blender.

There are a couple of editors that can manage video: the Compositor, the Movie Clip Editor, the Image Editor (only for still images), and the Video Sequencer.

This section describes only the interface of the Video Sequencer, to read more about usage of the Video Sequencer read the Video Editing section.

Editor Layout

The Video Sequencer is composed of multiple regions (see figure 1). They are described in more detail in the next sections. Figure 1 shows the combined Sequencer & Preview view type. This view can be broken up into the following regions:

Figure 1: Sequence Editor shown in the Sequencer & Preview view type.

Header (red), Preview (yellow), Sequencer (blue), Properties (gray), Panels & Tabs (yellow), Toolbar (purple).

标题栏

This region displays menus and buttons for interacting with the editor. The header changes slightly depending on the selected view type (see below).

预览

This region shows the output of the sequencer at the time of the playhead.

序列容器

This region shows timeline for managing the montage of strips.

属性

This region shows the properties of the active strip. Is divided into panels and tabs. Toggle on or off with N key.

工具栏

This region shows a list of icons, clicking on a icon will changes the active tool. Toggle on or off with T key.

视图类型

The Video Sequencer has three view types which can be changed with the View Type menu (see figure 1; top left).

序列容器

查看时间轴和片段属性。

预览

查看预览窗口和预览属性。

序列编辑器 & 预览

同时查看预览和时间轴以及两者的属性。

Tip

可以在单个工作空间中创建任意视图类型的多个实例。

性能

可以通过多种方式改善回放性能。对性能的最大影响是允许视频序列器缓存回放。缓存有两个级别，第一个是内存（RAM）缓存，默认下已启用该级别，但能根据可用的内存量增大。下一个缓存级别是磁盘缓存，该缓存将缓存的片段存储在磁盘上。磁盘缓存通常大于内存缓存，但其速度较慢。这两个缓存选项可在 偏好设置 中设置。

Another way to improve performance is by using Strip Proxies. These are used to cache images or movies in a file that is easier to playback by reducing the image quality by either decreasing the resolution and/or compressing the image.
