 Introduction
 ************
 
-Blender is a versatile software used for modeling, sculpting, 2D drawing, animation, and video editing.
+The Video Sequencer allows you to place images, videos, sounds, and scenes
-Most of the work is done in so-called editors:
+on a timeline and combine them into a new video. This section only describes its UI;
-tools for viewing and modifying your work through a specific part of Blender.
+to read more about its usage, see the :doc:`Video Editing </video_editing/index>` section.

-There are a couple of editors that can manage video:
-the :doc:`Compositor </editors/compositor>`, the :doc:`Movie Clip Editor </editors/clip/index>`,
-the :doc:`Image Editor </editors/image/index>` (only for still images), and the Video Sequencer.

 Performance

+Playback performance can be improved in 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,
+The method with the most impact is to allow the Video Sequencer to cache the playback.
-this is enabled by default but can be increased based on the amount of RAM available.
+There are two levels of cache: a memory cache, which is enabled by default
-The next level of cache is a disk cache which stores cached strips on disk.
+(and can be enlarged if RAM allows), and a disk cache, which is slower but has more capacity.
-A disk cache can generally cache more than a RAM cache, but it can be slower.
+Both of these can be configured in the :ref:`Preferences <prefs-system-video-sequencer>`.
-Both of these cache options can be configured in the :ref:`Preferences <prefs-system-sound>`.
 
 Another way to improve performance is by using :ref:`Strip Proxies <bpy.types.SequenceProxy>`.
-These are used to cache images or movies in a file that is easier to playback
+These are copies of source images and videos with a lower resolution and/or quality,
-by reducing the image quality by either decreasing the resolution and/or compressing the image.
+making them faster to load than the originals.
