简介

The Video Sequencer allows you to place images, videos, sounds, and scenes on a timeline and combine them into a new video. This section only describes its UI; to read more about its usage, see the Video Editing section.

编辑器布局

The Video Sequencer is composed of multiple regions. 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:

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 a timeline for managing the montage of strips.

侧栏

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

工具栏

This region shows a list of tools. Toggle on or off with T.

视图类型

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

Tip

It's possible to have multiple Video Sequencers in one workspace, each with its own view type.

性能

回放性能可由多种方式改善。

The method with the most impact is to allow the Video Sequencer to cache the playback. There are two levels of cache: a memory cache, which is enabled by default (and can be enlarged if RAM allows), and a disk cache, which is slower but has more capacity. Both of these can be configured in the Preferences.

Another way to improve performance is by using Strip Proxies. These are copies of source images and videos with a lower resolution and/or quality, making them faster to load than the originals.
