+## Overview
+
+The plugin allows you to import and export video files using the JavaCV interface to FFmpeg. 
+It supports all formats and compression methods known to ffmpeg (i.e. virtually all known video types).
+
+During import you can select the necessary frame range and perform the simplest operations on images like flip and convert to grayscale.
+The resulting sequence of images is displayed as a virtual image stack (optionally decimated) or converted to a 5D hyperstack with customizable field order and number of z-slices and time-frames.
+
+Export allows you to save the image stack or hyperstack to video in the required format and compression.
+
+The plugin depends on another plugin - [JavaCV Installer](https://imagej.net/plugins/javacv-installer), which must be installed in ImageJ (see Installation details below). 
+
+## Usage
+
+***Import***
+
+1. Select menu "Import Movie Using FFmpeg..." from the Import menu
+2. Specify the video file
+3. Configure import options in the user interface
+
+***Export***
+
+1. Make required image stack active
+2. Select the Save As menu item - "Export Movie Using FFmpeg..."
+3. Customize export options in the user interface
+4. Specify the video file to save
+
+## Installation in Fiji
+
+Running the plugin requires installation of the [JavaCV installer](https://imagej.net/plugins/javacv-installer), which installs the interface for FFmpeg.
+Although you can install the JavaCV installer and then add FFmpeg manually as described in the JavaCV installer description, 
+this is not necessary as the plugin will check for the availability of the required components and offer to download and install them automatically.
+
+Therefore, the following simple procedure is recommended:
+<ol>
+  <li>Install the video plugin </li>
+  <li>Run the import or export command, and the plugin will install everything by itself (several restarts of ImageJ will be required) </li>
+</ol>
+
+To install the video plugin:
+<ol>
+  <li>add VideoImportExport update site https://sites.imagej.net/VideoImportExport/ using the update sites manager </li>
+  <li>install the plugin normally using the updater </li>
+</ol>
+
+
