  * SECTION: gesvideotrack
  * @short_description: A standard GESTrack for raw video
+ *
+ * Sane default properties to specify and fixate the output stream are
+ * set as restriction-caps.
+ * It is advised, to modify these properties, to use
+ * #ges_track_update_restriction_caps, setting them directly is
+ * possible through #ges_track_set_restriction_caps, but not specifying
+ * one of them can lead to negotiation issues, only use that function
+ * if you actually know what you're doing :)
+ *
+ * The default properties are:
+ * - width: 1280
+ * - height: 720
+ * - framerate: 25/1
+ * - max-framerate: 25/1
+ * - views: 1 (related to stereoscopy)
