FLASH Video Captioning

[NOTE: This FLASH captioning tutorial is also available as an MS Word document and as a PDF text file.]

You can publish your video clips to the web as FLASH Video with closed captioning. FLASH Video has been widely popular ever since the advent of the YouTube video sharing website. The problem with YouTube however, is that the video segments don't include closed captions. Captions provide an aid to people with hearing disabilities. They are also particularly useful when the viewer is watching your video while situated in a noisy environment.

Samples of captioned FLASH video are available at the CSULB Chemistry TestTube site and at the CSULB Education Department video lessons site.

This web page provides a list of tools required to publish your own video to the web. All but one of the required software applications are available at no charge, either as an element included with your computer's operating system (e.g. Windows Movie Maker, WordPad, FTP application) or as a free download off the web (MAGpie2). However, the most essential application required for publishing FLASH video to the web is not free. That is the Adobe CS3 FLASH Professional, which includes the Adobe CS3 FLASH Video Encoder.

Besides a list of required tools, this website provides detailed step by step instructions on how to start with a video file on your local computer and eventually publish it out to a common web server. The CSULB web server is available to all CSULB students, instructor members and staff.

Feel free to contact Walter Gajewski with questions or suggestions by email to gajewski at csulb dot edu or by phone at (562) 985-2266.

Tools

Video editor

Use the editor of your choice. Create an avi video file. (or an mov file on a Mac). Episode 10 of TechTips includes instructions on saving a movie file in the avi format from within the free Windows Movie Maker.

FLASH CS3 Video Encoder (included as part of Adobe CS3 FLASH Professional)

Flash CS3 Encoder from Adobe (stand alone application that is included with FLASH CS3 Professional). Be sure to read the Best Practices for FLASH Video Encoding document made available from Adobe.

Text Editor

WordPad (or text editor of your choice). It is convenient to use the XML editor built into Dreamweaver.

MAGpie2

MAGpie2 can generate the required *.dfxp.xml (Distribution Format Exchange Profile) text file.

    MAGpie2 (Media Access Generator) is a free download from the WGBH National Center for Accessible Media. Make sure to follow the Magpie2 instructions carefully. However, you are probably better off ignoring the instruction to install the GRINS player. GRINS is no longer free. Just use Quicktime.

FLASH CS3 Professional from Adobe

This will include the FLASH CS3 Video Encoder as an included but separate file and, depending on which configuration of the CS3 suite you purchased, you may also have the Dreamweaver application available.

FTP (File Transfer Protocol) application

You can use any one of several FTP applications available. If you are developing websites with Dreamweaver, use the built in file upload feature. Other possibilities are the FireFTP extension for the Firefox browser, the latest version of Internet Explorer (see Bonus Material at the end of this document), WS_FTP for Windows PC’s, or Fetch for Mac computers.


Process



Video Editor

Make a beautiful video and save it as a Windows *.avi file or a Mac QuickTime *.mov file. [NOTE: Replace the asterisk with a word of your choice.] Save this file in a new, emply folder. For puprposes of this tutorial, call the folder "flash."

Adobe CS3 FLASH Video Encoder (included as part of Adobe CS3 FLASH Professional)

Convert the video file to the FLASH *.flv format:

  1. Launch the Adobe CS3 FLASH Video Encoder
  2. File/Add. . .
  3. Browse to the AVI file you want to convert to FLV

  29. Exit Adobe CS3 Flash Professional

Dreamweaver (optional)

(optional) You can pull the index.html file into a web authoring application (e.g. Dreamweaver) and add additional elements (images, links, annoying background music, the usual stuff).

FTP (file transfer protocol) Application

Use an application like Dreamweaver, WS_FTP, FireFTP for FireFox, Fetch (on a Mac), or the latest version of Internet Explorer (see bonus material below) to move only the necessary files out to the web server.
First, test these files locally by double-clicking the index.html file to launch the video in its own web page with the title and captions. The Full Screen and Captions buttons (part of the player controls) should work properly.

Only six files are required to make this work:

  1. *.flv (file generated by Adobe FLASH CS3 video encoder)
  2. *.dfxp.mxl (file generated by MAGpie2)
  3. *.swf (file generated by Adobe FLASH CS3)
  4. AC_Runactivecontent.js (file generated by Adobe FLASH CS3)
  5. SkinUnderAll.swf (file generated by Adobe FLASH CS3)
  6. index.html (file generated by Adobe FLASH CS3)

[NOTE: in each of the three cases above, the asterisks represent a word generated by the software applications.]

Publish the finished project out to a web server:

  1. Create a new folder (outside the current folder) into which you will archive the unnecessary files.
  2. Return to the original folder. It should contain only the six necessary files listed above (and files that represent the optional elements you might have added to the index.html web page).
  3. Use your preferred ftp application to move the entire folder out to your web folder on the remote server. At CSU Long Beach, the web folder is the htdocs folder.
  4. Test the results by launching a web browser and entering the newly created
    URL (web address), usually http://www.csulb.edu/~myaccount/flash/index.html where "myacount" would be replaced by your actual account name.

Bonus Material

Use the latest version of Internet Explorer as an FTP application:

  1. Open a folder that contains the files (or folders) you want to upload to the server
  2. Launch Internet Explorer
  3. In the space where you usually enter a web address (starting with http://www etc.), enter an ftp address (ftp://ftp.csulb.edu) and hit Enter.
  4. A plain page with the message FTP root at ftp.csulb.edu will appear.
  5. Follow the on-screen instructions to click Page, and then click Open FTP Site in Windows Explorer.
  6. Enter your User Name and Password and then click Log On
  7. A new window displaying your server files and folders will open. At the top, click on Folders.
  8. The Folders list will open as the left hand pane of the FTP window. Click on the folder designated for your web files. At CSULB this would be the htdocs folder.
  9. Now you can drag files and folders from your desktop into the right hand pane of the ftp window and they will be copied to your web server. If you haven’t done so already, drag over the flash folder created earlier. This should make your flash presentation with captioning available to the world at: http://www.csulb.edu/~myaccount/flash/index.html (where "myaccount" would be replaced by your actual account name).
