Filmography technique
The Ken Burns effect is a type of panning and zooming effect used in film and video production from non consecutive still images. The name derives from extensive use of the technique by American documentarian Ken Burns. This technique had also been used to produce animatics, simple animated mockups used to previsualize motion pictures, but Burns's 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.

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 segue 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. Many styles of limited animation, such as Japanese anime, also use still image panning to compensate for a lack of movement on screen. In anime production, a cel that is meant to be held and panned is called a "hold cel," and marked in production with the word "" (止メ). The American studio Filmation frequently used panning as a way to cut costs and fill time.

In film editing, the technique may be achieved through the use of a rostrum camera, although today it is more common to use digital editing. Virtually all non linear editing systems provide a tool to implement the simplistic effect, although only some software, 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 also labelled "Ken Burns Effect". On the Windows platform, AVS Video Editor, Windows Movie Maker, Pinnacle Studio, Serif MoviePlus, Avid Media Composer, Sony Vegas Studio (and Movie), Ulead VideoStudio, Adobe Premiere, and PicturesToExe also have pan and zoom features built in; otherwise, it is still available through third party extensions. Microsoft Photo Story creates videos with both random and customisable Ken Burns Effects automatically from selected images. ProShow Gold/Producer from Photodex and PhotoFilmStrip (free applications) also come with this effect. On the Mac platform, programs such as Final Cut Pro, Final Cut Express, iMovie, Adobe Premiere also have the ability. Adobe and Apple products (excluding iMovie) allow the user to set keyframes to further customize the process. The mobile video editing app KineMaster (for Android and iPhone) has "Ken Burns/Crop and Pan" as the default setting for photo cropping. The effect is found in various screensavers and slideshows, such as Apple. Windows PCs have the option of 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. Specific 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.

Steve Jobs contacted Burns to obtain the filmmaker's permission to create the term "Ken Burns Effect" for Apple's iMovie video production software zoom and pan effect (the description had been Apple's internal working title while the feature was in development). Burns initially declined, saying that he did not allow his name to be used for commercial purposes, but finally he had Jobs give him some equipment (which he later donated for nonprofit use) in exchange for permission to use the term in Apple products. In February 2014, Burns stated in his AMA ("Ask Me Anything", a question and answer interactive interview) 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 (the DNA of storytelling), 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", says he does not really understand what these Apple users are telling him and tries his best to make a quick escape.
