PowerPoint animation
PowerPoint animation is a form of animation which uses Microsoft PowerPoint and similar programs to create a game or movie. These animations are created slide-by-slide or by using PowerPoint's Custom Animation feature. Using Custom Animation, drawing tools and slides within PowerPoint, the animator makes a game or movie.
Custom Animation
Custom Animation is a set of effects which can be applied to objects in PowerPoint so that they will animate in the Slide Show. They can be added under the Custom Animation function (Slide Show | Custom Animation) or through the use of Visual Basic for Applications (VBA). PowerPoint 2000 and earlier versions introduced basic effects such as Appear, Dissolve, Fly In and so forth. In PowerPoint 2002/XP and later versions, the Custom Animation feature was improved, adding new animation effects grouped into four categories: Entrance, Emphasis, Exit and Motion Paths.[1]
Entrance effects can be set to objects so that they enter with animations during Slide Show. Emphasis effects animate the objects on the spot. Exit effects allow objects to leave the Slide Show with animations. Motion Paths allow objects to move around the Slide Show. Each effect contains variables such as start (On click, With previous, After previous), delay, speed, repeat and trigger. This makes animations more flexible and interactive, similar to [[Adobe Flaslide Show is clicked.This feature is the basis for the majority of PowerPoint games, which usually involve clicking objects to advance in the game.
Games
Using hyperlinks and Animation Triggers, one can create games such as Jeopardy, using the tools to maneuver from question to answer. Taking this same principle, the animator can also make more complex games similar to a dungeon game or escape-the-room game. In this format, the animator can create a domain where the player chooses to go right or left, or pick up objects, and so forth. The process takes time, but is generally cheaper and easier than using multimedia software such as Adobe Flash.
For more experienced users, Visual Basic for Applications (VBA) is also commonly used in PowerPoint to keep scores, enter inputs and so forth. With the help of VBA, animations can be programmed with more flexibility.[2]
Movies
PowerPoint can also function as a movie maker program. The animator using PowerPoint works similarly to an animator using cels, using a succession of slides to create the illusion of movement. Many tools within the PowerPoint program can be easily used for maximum effect. Drawing tools such as AutoShapes, contains lines, connectors, basic shapes, block arrows, flowchart components, 'freeforms' (AutoShapes drawn by the mouse on pen tool)
and banners, callouts and action buttons, help draw out a slide. Custom Animations and sound tools can also be used to help add excitement to the project and create interest in what might have been an otherwise dull presentation. The process of drawing out multiple slides takes time, but, again, it is considered to be less expensive and easier to use than buying and using professional graphics animation software.
Another way to produce these animations is by animating a cartoon as a single slide acting as a frame of film. This allows the slide show to run like an animated film. This is time consuming, but the artist has much more control and can do much more detailed and precise animation. It also allows control over the timing of the animation. This also make editing of the animation easier afterwards. On average, month's work of such animation usually ends up at about a minute in length. A three minute animation can take around three to four months to complete depending on the amount of detail, these lengthy cartoons usually run around 1,800 slides.
Using Custom Animation, cartoons or movies similar to those created in Adobe Flash can be done with PowerPoint. With minimum time, an animator can produce a simple show similar to a stick figure movie, where the body movements are animated using Motion Paths and Emphasis effects. An example released under PowerPoint Heaven,[3] has a section called the Shadow Fighter series which demonstrates PowerPoint movies.[4]
Distribution
While PowerPoint offers various distribution formats, notably in PowerPoint Show (.pps, .ppsx) and web page (.html), it should be noted that not all animation functions work accurately when saved as a web page[5] or executed with a PowerPoint Viewer.[6] Standalone EXE is also an alternate way for a creator to distribute his work with PowerPoint Viewer embedded.[7] This allows for the audience without access to PowerPoint to view these works, as well. Animation works can be easily created by amateur artists which are then distributed on the web[8], though technical knowledge is required to create a notable work. A screen capture can also be used to manually convert a PowerPoint movie into a more viable format (e.g. WMV).
Drawbacks
Though animations can be created easily using Custom Animations provided in Microsoft PowerPoint, it may be much more tedious to complete a project in PowerPoint than in professional animation programs such as Adobe Flash due to the absence of key frames and tweening.
When effects such as Emphasis Grow/Shrink and Spin are applied to objects, they may appear to be jagged or pixelated when previewing in the slide show. In addition, excessive use of these effects may degrade the slide show's performance. (PowerPoint's built in Hardware Graphics Acceleration feature does help in minimizing these setbacks, however[9] which requires a video card that supports Microsoft Direct3D.)
PowerPoint 2000 and later versions introduced macro security to help protect computers from malicious code within a PowerPoint presentation. This led to disabling all VBA or macro code by default, causing presentations containing codes unable to run properly. This complication can be easily fixed by adjusting the macro security settings to Low.[10] Security Warning in PowerPoint 2007 alerts the user of macros in a presentation as soon as it is opened, giving the option to run the presentation with or without the macros enabled.
