The Ken Burns effect is a type of panning and zooming effect used in video production from still imagery. The name derives from extensive use of the technique by American documentarian Ken Burns. The technique, previously known as "animatics", predates his use of it, but his name has become associated with the effect in much the same way as Alfred Hitchcock is associated with the dolly zoom. The feature enables a widely used technique of embedding still photographs in motion pictures, displayed with slow zooming and panning effects, and fading transitions between frames.
Usage
The technique is principally used when film or video material is not available. Action is given to still photographs by slowly zooming in on subjects of interest and panning from one subject to another. For example, in a photograph of a baseball team, one might slowly pan across the faces of the players and come to a rest on the player the narrator is discussing. By employing simulated parallax, a two-dimensional image can appear as 3D, with the viewpoint seeming to enter the picture and move among the figures. The effect can be used as a transition between clips as well. For example, to from one person in the story to another, a clip might open with a close-up of one person in a photo, then zoom out so that another person in the photo becomes visible. The zooming and panning across photographs gives the feeling of motion, and keeps the viewer visually engaged.
In film editing, the technique may be achieved through the use of a rostrum camera, although today it is more common to use software. Virtually all non-linear editing systems provide a tool to implement this technically simple effect, although only some systems, such as iMovie and Openshot for Linux, specifically call it a Ken Burns Effect; it is usually simply referred to as pan and zoom. Final Cut Pro, Apple TV and Apple's iMovie video editing program include a photo slideshow option labelled "Ken Burns Effect". On the Windows platform, 4K Slideshow Maker by 4KDownload, AVS Video Editor, Windows Movie Maker, Pinnacle Studio, Serif MoviePlus, Avid Media Composer, Sony Vegas Studio, Ulead VideoStudio, Adobe Premiere, and PicturesToExe also have pan and zoom features built in or available through third-party extensions which may be used to achieve the effect. Microsoft Photo Story is a free application that creates videos with both random and customisable Ken Burns Effects automatically from selected images. ProShow Gold/Producer from Photodex is a favorite application by still photographers that use this effect to great measure. Another free multiplatform Ken Burns effect application is PhotoFilmStrip. On the Mac platform, Final Cut Pro, Final Cut Express, iMovie, Adobe Premiere, and others also have the ability. Particularly, Adobe and Apple products allow the user to set keyframes to further customize the process. The mobile video editing app KineMaster has "Ken Burns / Crop and Pan" as the default setting for photo cropping. The effect is found in a great number of screensavers and slideshows. Apple uses it in their screensavers. Windows PCs can use Greg Stitt's "MotionPicture" and Gregg Tavares's "Nostalgic", among others. The effect can also be seen in the N73 smartphone by Nokia, applied to the slideshows the phone creates from the pictures stored in it. Many seventh-generation video game consoles also feature versions of this effect, including Nintendo's Wii Photo Channel, Sony's PlayStation 3 and within the Last.fm app for Xbox 360.
Use by Apple
contacted Burns to obtain the filmmaker's permission to use the term "Ken Burns Effect" for Apple's video production software. Burns initially declined, saying that he did not allow his name to be used for commercial purposes. Instead, Burns had Jobs give him some equipment in exchange for permission to use the term in Apple products. In February 2014, Burns stated in his AMA on Reddit that Steve Jobs "asked my permission. I said yes. And six billion saved wedding, bar mitzvahs, vacation slideshows later, it's still going. But our attempt to wake the dead relies on a much more nuanced and complicated relationship to the photograph, as well as the soundtrack." Burns says that on occasion, strangers will stop him on the street to enthusiastically describe how they use the Ken Burns Effect on their Apple software or ask him questions. Burns, who writes his speeches longhand and calls himself a "Luddite", claims not to really understand what these Apple users are telling him and tries his best to make a quick escape.
