Using multimedia
Some of the most exciting pages on the web use multimedia items such as sound, movies or animation. If you have multimedia items
that you wish to display on the web, it can often be the case that you can add them to your page in Freeway in the same way as adding
text or graphics—by creating boxes on the page to hold them or by dragging and dropping the file onto your page.
Some multimedia content requires additional “plug-in” software in the browser to properly display, or sometimes the format used for
the multimedia files may be completely unsupported—so it is important to understand the current level of support in browsers for each
type of multimedia file so you they can be made to work on the widest range of device for the vast majority of web visitors.
Multimedia content in Freeway is often referred to as “plug-in” content and it is important to note that plug-in content cannot be
previewed in Freeway’s Page view. However, some can be seen working in Preview mode, which is based on the same “engine” that
drives Apple’s Safari browser, but sometimes the functionality has been “sandboxed” and will not play until it has been uploaded live to
the web unless you edit the code first (by inserting http: before the // in the embed code supplied by YouTube for example).
When playing certain kinds of multimedia content you can specify additional or optional parameters using Actions to control how it
displays, and any such Actions will be listed in the appropriate section of this chapter.
If you use very large video or audio files on your web page, it is generally a good idea to let the visitor know what they will encounter
on the page before it occurs. This gives visitors the freedom to decide in advance if they wish to view it or not, as it can be frustrating to
wait for a very long time to download over a slow connection.
In the past it was often necessary to offer alternative options for certain multimedia files so the visitor would be able to choose their
preferred file type to use. More recently, however, support in modern browsers is far more universal, and it is now possible to include
automatic “fallback” options so that if one file type is not supported, another file type will be offered for the visitor’s browser to use.
Note 1: Many modern browsers ship with recent multimedia plug-ins. However, while many include Flash plug-ins as standard,
many PC browsers do not include the QuickTime plug-in. It is important to take this into account when considering including
QuickTime-based multimedia content in your designs.
Note 2: Plug-in content will always play on top of other items on the page, even if other layered items are above the box
item containing the plug-in content. If you want to prevent this default behavior (which can only be done in Freeway Pro, you
might want to try selecting the item you want to appear above the multimedia content (such as a CSS Menu’s drop-down sub-
menu), go to Item>Extended, click on the “Div style” tab, then enter the Name/Value pair of z-index and 99 to force the item
to display above the plug-in content. If you still find that the plug-in content is appearing above other items on your page, Pro
users can select the item on the page again and add another Name/Value pair—this time using wmode and transparent.
Types of multimedia content
HTML5 video
Cross-browser support for HTML5 video is now very good—and it should be used for offering video content wherever possible. The
reason it is considered to be the best method for offering video is because it offers alternative file formats to be used if HTML5 is not
supported (such as in Firefox for Mac and PC) and also because it can be made to fall back to Flash for older browsers and some mobile
devices.
How to offer a movie file as HTML5 video
The first thing you need to do is to save your movie file so it is encoded as H.264 and saved as either an .mp4 or .m4v file. If the file
was not offered in that format you can usually convert it very quickly by using a free video converter application such as Miro Video
Converter http://www.mirovideoconverter.com/ or by using a free online service such as the one at OnlineConvert.com http://video.
online-convert.com/convert-to-mp4 . Both of these will let you
convert many different video file types to MP4.
Once you have your .mp4 or .m4v file you can drag and drop it
on the Freeway page and then, with the item selected, look at the
options in the Item Output Settings tab of the Inspector.
• Type: If you have your page set to HTML5 or XHTML5, this
popup will be set to Video by default, which means that the video
will be output by Freeway as HTML5 video. If you have the page
set to any other HTML level (HTML 4.01 Transitional, XHTML 1.0
Transitional, etc.) the popup will display as QuickTime because the
page will not validate correctly unless it has an HTML5 declaration
in the head tag.
