LEARNING OBJECTIVES
1. Introduce Adobe Flash as an ideal multimedia format for developing and delivering online electronic educational
content for the radiologist educator.
2. Demonstrate basic features of Adobe Flash Professional for creating Flash movies.
3. Show how to create a short Flash video clip from a sequence of radiographic images.
4. Show how to create a basic Flash based multimedia educational presentation.

ABSTRACT
Adobe Flash is a widely compatible, versatile multimedia format for delivering animated graphics, interactive
content, digital video and sound over the Internet. Many commercial websites, news organizations and educational
websites use Flash extensively to deliver multimedia content. It is also an ideal format for online multimedia
educational presentations incorporating slides, graphics, images, narration and video. Flash movies can be used to
display image animations and video clips such as a stacked sequence of radiographic images, cine clips of moving
structures or a sequence of 3-D images. The purpose of this course is to demonstrate the basics of creating Flash
movies using Adobe Flash Professional. The attendee will learn how to create short Flash video clips of
radiographic image sets and how to create multimedia educational presentations suitable for web distribution in the
Flash format. The use of third party tools for converting existing PowerPoint presentations into Flash format will
also be discussed. No prior experience with Adobe Flash Professional is necessary as this course is designed as
an introduction to the Flash development environment.

FAQ: FLASH for the Radiologist

Background

What is FLASH?

          Adobe Flash or simply Flash refers to the Adobe Flash Player and the Adobe Flash Professional authoring
          program. Flash Professional can be used to create web applications, games and movies. The Flash
          Player is a client application available in most common web browsers. It supports vector and raster
          graphics1, a scripting language called ActionScript and bi-directional streaming of audio and video. Flash
          was introduced in 1996 and has become a popular method for displaying animation and interactivity in web
          pages. Flash is commonly used to create animation, advertisements, various web-page components, to
          integrate video into web pages and more recently to develop Internet applications. Flash files, traditionally
          called ―Flash movies‖ have a .swf file extension and may be an object of a web page or ―played‖ in a
          standalone Flash Player.

          Flash was initially released in 1996 by Macromedia as a vector based web animation tool. Users initially
          had to visit the Macromedia website to download the software. Over the ensuing years, Flash and Flash-
          based content became increasingly popular and by 2000 the Flash Player was being distributed with all
          AOL, Netscape and Internet Explorer browsers. Additional features were added including scripting
          language, support for MP3 audio and improved video support. According to Adobe, 99% of Internet-
          enabled desktops worldwide currently have Flash Player installed. 2 This compares with Java installed on
          85%, Microsoft Windows Media Player installed on 84% and Apple QuickTime Player installed on 67% of
          desktops in the same survey. Versions of Flash Player are available for all major platforms, browsers as
          well as many mobile devices. Adobe reports an installed base of over 750 million Internet connected
          desktops and mobile devices. Therefore, Flash is now a widely compatible Internet software environment.

Where is Flash being used on the web today?

          Due to widespread compatibility and the ability of Flash to handle graphics, animation, audio, video and
          user interaction, Flash is one of the most utilized media formats on the web today. 7 of the 10 most
          popular websites use Flash in some form. NewYorkTimes.com uses Flash to display video,
          advertisements and sets of photographs. Google video and YouTube both use Flash as their preferred
          format. Yahoo uses Flash to display video and advertisements. Amazon.com uses Flash for
          advertisements, to stream audio and to display some product images.

          Flash is being used extensively for web-based distance learning. Many sites that deliver online courses or
          online degrees are now using Flash to deliver their educational content over the web. RSNA is now using
          Flash as the primary method for streaming refresher courses from the annual meeting on its website. The
          slides, graphics, text transcript and audio from the original presentation can be integrated into an online
          web based presentation for at home CME that requires only a modest amount of bandwidth.

          Have you ever seen a slick graphic animation or interactive display on a website and wonder how did that
          website do that? Right click over the object. If the context sensitive menu that pops up includes the option
          ―About Adobe Flash Player‖ as one of the options, it was done using Flash.

Why use Flash over HTML alone?

          Hypertext Markup Language (HTML) alone is fine for creating static websites where text and images are
          placed a fixed positions. Even with plain HTML, website developers must design sites carefully to achieve
          a similar appearance across platforms and browsers. Web pages may display quite differently between
          platforms and browsers due to variability in installed fonts, font size, screen size, browser size and colors.

  Vector graphics is the use of geometrical primitives such as points, lines, curves, and polygons, which are all based upon mathematical
equations to represent images in computer graphics. Raster graphics represent images through a rectangular grid of pixels, or points of color
viewable via a computer monitor, paper, or other display medium. Raster graphics deal more practically than vector grap hics with photographs
and photo-realistic images, while vector graphics often serve better for typesetting or for graphic design.

Adobe Flash Hands on Tutorial                                            RSNA 2007                                               Page 2 of 12
        HTML alone does not really support dynamic sites where text, images and animations are moving around
        on the screen. Traditionally these effects were achieved with animated GIF images or java applets.
        Animated GIFs can be used for simple animations but can take a long time to load since each step in the
        animation requires a separate image to be downloaded. Animated GIFs also lack interactivity. Java
        applets can be used to create animations and interactivity, but java applets require programming skill and
        can be less stable than Flash movies.

What are alternatives to Flash?

        Flash is somewhat unique in its ability to display animations with only minimal bandwidth requirement
        because it uses vector graphics and was designed initially as an animation program. For the purposes of
        displaying video over the web, there are multiple players and formats other than Flash capable of web-
        based video streaming, including QuickTime, Windows Media Player and RealPlayer. QuickTime comes
        installed on Apple computers but Windows users must download the Windows-based plug-in. Windows
        Media Player comes installed on most versions of Windows but Apple users must download and install the
        Mac-based plug-in. RealPlayer must be downloaded and installed on both Apple and Windows platforms.
        In contrast, as Flash Player is already installed on almost all platforms and browsers, you can be fairly
        confident that the maximum number of people can play a Flash based video without having to download
        any additional software. Other benefits of Flash based video include user friendly startup, watermarking,
        ability to make your own custom controls and piracy protection.

        For displaying pure video, Flash is the most compatible format; however Flash video may take up more
        space for the same amount of quality compared to other formats like H.264, .mov, .mp4 and .wmv.
        Displaying Flash video will also require you to convert your video to Flash and then set it up to work with a
        Flash player. This is not very difficult, but is more work than just uploading a completed .mov or .wmv video
        file to your website. Another advantage of Flash for video is that unless your visitors are especially savvy,
        they can only watch the video, not download it—minimizing piracy.

How can I convert my digital video to the Flash format?

        Displaying Flash video will also require you to convert your video to Flash and then set it up to work with a
        Flash player. This is not very difficult, but is more work than just uploading a completed .mov or .wmv video
        file to your website. Flash Professional can handle almost any native digital video format and convert it to
        Flash video (.flv). There are also standalone video converters that can convert most video formats to
        Flash.

What are the file types / extensions involved in creating a Flash movie?

        .fla       This is the "project" file, from which you export your movie. Never upload this to your server.
                   Analogous to .PSD files for Photoshop.

        .flv        Flash video file: contains compressed video for playback within a .swf movie or .swf player if you
                   are including externally linked video in your project. You upload this to the server.

        .swf       ―swiff‖ This is the movie file that is played by the Flash Player. It may contain links to .flv files if
                   flash video is utilized. You upload this to the server.

Where would Flash be useful for educational purposes?

        Flash is most appropriate for delivering web-based content; although it could also be used for CD-ROM or
        DVD-ROM based content such as electronic CME courses.

              Animations consisting of a stack of radiographic images for display on an educational website.
              Flash animation consisting of cine images of a moving structure.
              Flash based presentation incorporating text, graphics, images, video, narration.
              Flash based video demonstrating how to perform an interventional procedure on an educational
               website.

What are alternatives to Flash for delivering Web-based educational content?

        HTML alone       Capable of integrating text and images. Much educational content does not require
                         animations or video

        PowerPoint       PowerPoint presentations can be exported to HTML format and uploaded to your website;
                         however there are several drawbacks with this approach. Content is not readily compatible
                         between different browsers and appears best on Internet Explorer browser (Microsoft).
                         Content can be copied or ―stolen‖. Output may be inconsistent between browsers and file
                         sizes can be large.

        Windows Media (*.wmv / *.avi) Streaming video format. Can customize output size and bit rate. Generally
                      file size is large and often requires a broadband connection. Users must have Windows
                      Media Player installed (OK for most Windows platforms but Mac users must download and
                      install a plug-in). Quality degrades as bandwidth is reduced.

        QuickTime (Apple *.mov) Similar to Windows Media Video. Windows users must download and install a
                      plug-in. Compatibility and large file size are drawbacks. It is possible to export PowerPoint
                      presentations on the Mac platform directly to QuickTime movies (which then need to be
                      compressed further). This option in not available on Windows versions of PowerPoint.

        RealNetworks Another video format that is even less compatible than QuickTime and Windows Media.
                     All users must download and install the Real plug-in.

        Scripting and server side techniques: JavaScript, java applets, cgi-perl, Coldfusion, ASP. All can be used
                        to deliver interactive content (quizzes, user feedback) but require some programming
                        expertise. None do animation or video well.

What are alternatives to Flash Professional for creating Flash movies?

        While Flash Professional is the principal development environment for creating flash movies (.swf files),
        there are alternative ways of creating flash movies without learning Flash Professional.
                                                                                           rd
        Existing digital video can be converted to Flash video (.flv) through a variety of 3 party conversion tools.

        Many video editing tools are capable of exporting the video in Flash format (.flv or .swf).

        3rd party conversion tools are available for converting PowerPoint presentations into Flash movies. We
        reviewed a number of these tools last year and found several that are quick, easy to use and deliver good
        output. This may be the easiest way to go if your intent is to adapt an existing PowerPoint presentation to
        a web version for online distribution. These tools can be quite powerful and obviate the need to totally re-
        create the PowerPoint in Flash Professional manually. The best tools can accurately convert the slides,
        images, symbols, animations, slide notes, narration and timing into a Flash movie. Converting embedded
        video within the PowerPoint can be challenging.

What are alternative export formats for my Flash project?

        Flash documents (.FLA file) can be exported into a variety of formats besides the standard Flash movie
        (.SWF file). Individual frames can be exported as single images and the entire Flash document can be
        exported in an alternative video format or a stacked sequence of images. Since Flash is currently the most
        web compatible video format, it is generally suitable to display animated content only in Flash. However,
        there may be circumstances when you wish to have multiple formats available or want to display snapshot
        images of your Flash movie elsewhere on your website. Flash documents can be exported in the following
        formatd by selecting File | Export | Export Image…. or Export Movie…. within Flash Professional:

        Video Formats                                         Image Sequences (stacked images)
        Flash (*.swf)                                         EMF Sequence (*.emf)
        Windows AVI (*.avi)                                   WMF Sequence (*.wmf)
        QuickTime (*.mov)                                     EPS 3.0 Sequence (*.eps)
        Animated GIF (*.gif)                                  Adobe Illustrator Sequence (*.ai)
                                                              DXF Sequence (*.dxf)
                                                              Bitmap Sequence (*.bmp)
                                                              JPEG Sequence (*.jpg)
                                                              GIF Sequence (*.gif)
                                                              PNG Sequence (*.png)

How do I get Flash?

        Flash Player is free and comes preinstalled on all major web browsers. You may be prompted to download
        and install the latest version of the player if the site you are accessing requires the latest version of the
        Flash Player (latest version is Flash Player 10.0). Flash Player only allows you to play Flash movies (.SWF
        files).

        To create Flash movies, you need Flash® Professional, which is the developing environment for Flash.
        Adobe has just released a new version, Adobe® Flash® CS4 Professional (version 10.0). It can be
        purchased in a standalone version from Adobe for $249 (educational discount) or $699 retail. Flash® CS4
        Professional is part of the Creative Suite 4 which bundles several Adobe products aimed at the website
        developer. Adobe® Creative Suite 4 Web Standard is $399 (educational) and includes Adobe®
        Dreamweaver® CS4, Adobe® Flash® CS4 Professional, Adobe® Fireworks® CS4 and Adobe®
        Contribute® CS4. The CS4 Web Premium version adds Photoshop® CS4 Extended, Adobe® Illustrator®
        CS4 and Adobe® Acrobat® 9 Professional to the bundle and costs $499 educational. Dreamweaver® CS4
        is a web development tool for designing, developing and maintaining websites. Fireworks® CS4 is a tool
        for developing web user interfaces and creating and optimizing images for the web.

        It is also possible to create Flash movies without Flash Professional. Many third party software packages
        are capable of generating output in the Flash file format (*.swf). See Alternatives to Flash Professional
        above.

Introduction to FLASH Workspace
Opening Flash

Flash Professional Workspace
Multiple Panels
        Similar to Photoshop
        Panels can be shown / hidden using Window menu. Can always go back to the default layout or hide all
        panels
        Workspace can be extensively customized by rearranging panels

           Tools Panel: contains tools for drawing, coloring, selecting
           Stage Panel: displays what will be shown in the Flash movie
           Properties Panel: context sensitive property information based on the selected object. If no object is
            selected, the Properties panel displays information on the Flash document (size, publish settings,
            background color and frame rate).
           Timeline: displays animation timeline in frames
             Organizes and controls a document’s content over time in layers and frames.
             Like films, Flash documents divide lengths of time into frames.
             Layers are like multiple film strips stacked on top of one another, each containing a different image
                that appears on the stage
           Panel Well: can contain library panel & additional panels
           Workspace Layouts can be saved and set to serve as your default layout
           Window menu controls which panels are visible. If you don’t see what you want, go to the Window
            Menu. To hide all panels, F4
           New Flash documents can be displayed as new windows or new tabs
           Help: Flash Help (internal help) can browse and search F1

Terminology: Frames & Keyframes
   • Frame….Flash divides lengths of time into frames in the timeline

   • Keyframe….frame in which you define a change to an object’s properties for an animation or include
      ActionScript code to control some aspect of the document

   • Tween….Flash can automatically fill in the frames between keyframes to produce fluid animations without
      having to draw each individual frame. Called ―tweening‖ for between

Exercise 1: Creating a Flash Movie from a stack of Radiologic Images

    Goal: Create a Flash Movie (.swf) of a stacked sequence of radiologic images for your website

Steps
   1. Launch Flash
   2. Select New from the File Menu
   3. Select Flash File (ActionScript 2.0) then OK
   4. Select File | Import | Import to Stage…. (or Ctrl-R)
   5. Navigate to Flash Course\Exercise1\CardiacCT\1001.jpg and click open
         -You will be prompted to import all of the images in the folder (they are numbered sequentially) YES
         -Each image will be imported as a KeyFrame on the timeline
   6. Click anywhere on the stage outside the images to deselect the images
         -Properties panel will then reflect Properties for the Document (instead of the images)
   8. Click on Size Button on Properties Panel (says 550 x 400 pixels)
         -Document Properties dialog pops up
   9. Select Match: Contents
         -This will resize & recenter the stage to fit the content of the movie (the imported images)
   10. Save Flash file: File | Save As…
         -Call it Exercise1.FLA in the Working Folder
   11. View the movie: File | Publish Preview | Default (HTML) or F12

   Export Options
       File | Export | Export Movie….
       -Choose Animated GIF as an example
       -Reduce size of Animated GIF to 250 pixels

   Image Import Considerations
      •   All major Image formats are supported for import
      •   Flash will compress the imported file if not already compressed using JPEG algorithm (you can set the
          quality factor) when you publish the file
      •   Flash will leave imported JPEG images at their imported quality (will not recompress)
      •   Limited image editing tools in Flash once imported (cannot crop)
      •   Best to optimize image first (Photoshop, Fireworks or ImageReady), resize & save as JPEG
      •   Smallest file size with adequate quality: remember web only needs 72 dpi
      •   Size: Ideally No larger than 640 pixels wide (although you can scale in Flash)
      •   For multiple images in sequence, name files sequentially: CT1.jpg, CT2.jpg, CT3.jpg

Exercise 2: Incorporating Video

Video can be incorporated in 2 different ways:
     Embedded: the entire video is imported into the main .swf file (can create large main file size)
     Play externally as a .flv file (Best for clips >30 sec & those with sound)
Embedding video
     Makes the main file bigger
     Quality isn’t as good as playing an external .flv file
     Appropriate for very short video (<30 sec) without sound where you don’t want to maintain separate files or
        when you need precise frame by frame control
External video file
     Video is imported, compressed using one of the Flash Player’s two supported codecs and saved as a .flv
        file
     The main .swf file will contain links to the .flv file. Both files need to be uploaded to your website
What video formats can be imported into Flash ?
     QuickTime (.mov)
     Digital video (.dv)
     MPEG (.mpg or .mpeg)
     Windows Media (.asf or .wmv)
     Video for windows (.avi)
Video Compression
     Flash handles video compression through the use of codecs (compressor/decompressor)
     Sorenson Spark (older but works on Flash 6 & 7 players)
     On2 VP6 (newer, better quality but requires Flash 8 player)

If you have an existing PPT file you want to web-distribute:
Use of 3rd party tools for doing a PPT to FLASH conversion
    We evaluated 20 PowerPoint to FLASH 3 rd party conversion tools last year. They come in two general forms:
    PowerPoint plug-ins and Screen recording software. Conversion tools that work as a PowerPoint plug-ins are
    relatively easy to use. Narration can be added by recording sounds within PowerPoint. Then the conversion
    tool is launched within PowerPoint to trigger the conversion process. Animations, narrations, slide notes and all
    slides are captured and turned into a Flash based presentation. Screen recording software works by capturing
    everything on the screen or within a window as a video. Any presentation software can be utilized (not
    PowerPoint specific). Mouse movement is captured. The recording can then be exported in multiple video
    formats, including Flash video. File sizes tend to be much larger than with the PowerPoint plug-in tools.

Example: PPT  Flash Conversion Steps
    Choose PowerPoint Presentation
    Add narration to PowerPoint presentation within PPT
          - Best to use a hands free / lapel microphone or USB Condenser Microphone
          - PowerPoint will record slide timings along with the narration that will be captured by the PPT to
              FLASH converter
          - To Pause or Resume Narration Recording: Right Click……Pause Narration or Resume Narration
    Launch 3rd party tool to convert to FLASH
          - PowerConverter is shown in this example
          - Follow steps in Dialog Box to convert the narrated PowerPoint file to FLASH (or EXE) format
          - Choose FLASH player style: simple, or with thumbnails & speaker notes
          - View the Result
    Distribute Output:
          - Upload to web server
          - Can e-mail link to website
          - Place on shared network drive
          - Distribute on CD-ROM
