Введение

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.

Макет редактора

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).

Колонтитул

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

Предварительный просмотр (preview)

This region shows the output of the Sequencer at the time of the Playhead.

Секвенсор (sequencer)

This region shows timeline for managing the montage of strips.

Свойства (properties)

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

Совет

It is possible to create multiple instances of any view type in single workspace.

Производительность (performance)

Playback performance can be improved through several ways. The biggest impact on performance is to allow the Video Sequencer to cache the playback. There are two levels of cache, the first is a RAM cache, this is enabled by default but can be increased based on the amount of RAM available. The next level of cache is a disk cache which stores cached strips on disk. A disk cache can generally cache more than a RAM cache, but it can be slower. Both of these cache options can be configured in the Preferences.

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.
