+Video
+=====
+
+Validates that a file is a valid video that meets certain constraints (width, height,
+aspect ratio, etc.). It extends the :doc:`File </reference/constraints/File>` constraint
+and adds video-specific validation options.
+
+.. versionadded:: 7.4
+
+    The ``Video`` constraint was introduced in Symfony 7.4.
+
+==========  ===================================================================
+Applies to  :ref:`property or method <validation-property-target>`
+Class       :class:`Symfony\\Component\\Validator\\Constraints\\Video`
+Validator   :class:`Symfony\\Component\\Validator\\Constraints\\VideoValidator`
+==========  ===================================================================
+
+Basic Usage
+-----------
+
+This constraint is most commonly used on a property that stores a video file as a
+:class:`Symfony\\Component\\HttpFoundation\\File\\File` object. For example, suppose
+you're creating a video platform and want to validate uploaded video files::
+
+    // src/Entity/VideoContent.php
+    namespace App\Entity;
+
+    use Symfony\Component\HttpFoundation\File\File;
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    class VideoContent
+    {
+        #[Assert\Video(
+            maxWidth: 1920,
+            maxHeight: 1080,
+            maxSize: '100M',
+            mimeTypes: ['video/mp4', 'video/webm'],
+        )]
+        private File $videoFile;
+    }
+
+.. warning::
+
+    This constraint requires the ``ffprobe`` binary to be installed and accessible
+    on your system. The constraint uses ``ffprobe`` to extract video metadata.
+    You can install it as part of the `FFmpeg package`_.
+
+Options
+-------
+
+``allowedCodecs``
+~~~~~~~~~~~~~~~~~
+
+**type**: ``array`` **default**: ``['h264', 'hevc', 'h265', 'vp9', 'av1', 'mpeg4', 'mpeg2video']``
+
+Defines which `video codecs`_ are allowed. If the video uses a codec not in this
+list, validation will fail::
+
+    // src/Entity/VideoContent.php
+    namespace App\Entity;
+
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    class VideoContent
+    {
+        #[Assert\Video(
+            allowedCodecs: ['h264', 'hevc'],
+        )]
+        private $videoFile;
+    }
+
+``allowedContainers``
+~~~~~~~~~~~~~~~~~~~~~
+
+**type**: ``array`` **default**: ``['mp4', 'mov', 'mkv', 'webm', 'avi']``
+
+Defines which `video container formats`_ are allowed::
+
+    // src/Entity/VideoContent.php
+    namespace App\Entity;
+
+    use Symfony\Component\Validator\Constraints as Assert;
+
+    class VideoContent
+    {
+        #[Assert\Video(
+            allowedContainers: ['mp4', 'webm'],
+        )]
+        private $videoFile;
+    }
+
+``allowLandscape``
+~~~~~~~~~~~~~~~~~~
+
+**type**: ``boolean`` **default**: ``true``
+
+If set to ``false``, the video cannot be landscape oriented (i.e., the width
+cannot be greater than the height).
+
+``allowPortrait``
+~~~~~~~~~~~~~~~~~
+
+**type**: ``boolean`` **default**: ``true``
+
+If set to ``false``, the video cannot be portrait oriented (i.e., the width
+cannot be less than the height).
+
+``allowSquare``
+~~~~~~~~~~~~~~~
+
+**type**: ``boolean`` **default**: ``true``
+
+If set to ``false``, the video cannot be a square (i.e., the width and height
+cannot be equal).
+
+``maxHeight``
+~~~~~~~~~~~~~
+
+**type**: ``integer``
+
+If set, the height of the video file must be less than or equal to this value
+in pixels.
+
+``maxRatio``
+~~~~~~~~~~~~
+
+**type**: ``float``
+
+If set, the aspect ratio (``width / height``) of the video file must be less
+than or equal to this value. For example, a square video has a ratio of 1,
+a 16:9 video has a ratio of 1.78, and a 4:3 video has a ratio of 1.33.
+
+``maxWidth``
+~~~~~~~~~~~~
+
+**type**: ``integer``
+
+If set, the width of the video file must be less than or equal to this value
+in pixels.
+
+``minHeight``
+~~~~~~~~~~~~~
+
+**type**: ``integer``
+
+If set, the height of the video file must be greater than or equal to this
+value in pixels.
+
+``minPixels``
+~~~~~~~~~~~~~
+
+**type**: ``float``
+
+If set, the total number of pixels (``width * height``) of the video file must be greater
+than or equal to this value.
+
+``maxPixels``
+~~~~~~~~~~~~~
+
+**type**: ``float``
+
+If set, the total number of pixels (``width * height``) of the video file must be less
+than or equal to this value.
+
+``minRatio``
+~~~~~~~~~~~~
+
+**type**: ``float``
+
+If set, the aspect ratio (``width / height``) of the video file must be greater
+than or equal to this value.
+
+``minWidth``
+~~~~~~~~~~~~
+
+**type**: ``integer``
+
+If set, the width of the video file must be greater than or equal to this value
+in pixels.
+
+``mimeTypes``
+~~~~~~~~~~~~~
+
+**type**: ``array`` or ``string`` **default**: ``video/*``
+
+See the :ref:`File mimeTypes option <reference-constraints-file-mime-types>` for a
+description of this option and a list of common video MIME types.
