Ken Burns Effect
Ken Burns Effect
When incorporating a photograph into a video production, it is common to pan across and zoom into the still image. The American filmmaker Ken Burns used this extensively in his documentatries and the effect is often named after him. This Mathematica implementation presents the full picture in the "setup" phase. A green starting box (which can be moved using the locator and resized using the "start" slider) and a red ending box (similarly moveable and resizable) define the starting and ending regions for the effect. In the "pan & zoom" phase, the "step" through pan slider moves the center of the image smoothly from the starting point to the ending point, resizing smoothly from the size of the green box to the size of the red box. A variety of images from the Wolfram image library can be selected from the image menu.
