Preparing and publishing applications.
Before a multimedia application is ready for distribution and publishing it must be prepared. Preparing the application for distribution requires optimizing files, pictures, sound and video for use either on the internet or other medium. The main difference in between publishing to CD/DVD and the internet is that particular attention must be paid to file size when publishing on the internet. CDs hold up to 700mb and DVDs up to 7 GB whereas on the internet any files must be downloaded as they are needed.
When using the internet as the distribution medium file sizes are very important as large files can take a long time to be downloaded and displayed in a browser. Most applications used for creating multimedia components have built-in functions for optimizing pictures, video and sound. Drawing applications like Fireworks, Photoshop and Paint.net have options that allow the user to reduce the size of the file by reducing the quality of the picture. Different file types can also be used to reduce the size. Options for .gif files allow the user to select the number of colours in the picture and add transparency. Jpg options allow the user to reduce the quality of the picture and remove any unused colours meaning the user can find a balance between picture quality and file size. Files like .jpg and .png can be very large and would take a long time to download; this can affect the look of the page while the browser downloads the image. If there are too many large files to be viewed on a web page the page can take a long time to load and there is every possibility that the user will get fed up waiting and leave the page. Files like .jpg and .png can be very large and would take a long time to download; this can affect the look of the page while the browser downloads the image. If there are too many large files to be viewed on a web page the page can take a long time to load and there is every possibility that the user will get fed up waiting and leave the page.
Sound editing applications allow the user to record sound for a multimedia presentation and export the recording in a variety of file types including .mp3 and .wav. Mp3s allow the use of CD quality sound without the large file sizes.
Video and animation applications like Flash and Windows Movie Maker allow the user to select the quality and size of the video and sound. Some programs allow the user to set a size and the program publishes the file to meet the set size.
When publishing to CD or DVD file sizes are not as important as files are already on the system on the CD or DVD and do not need to be downloaded. On a CD or DVD instead of size like when publishing to the internet the user can focus on quality.

Online and Offline delivery mediums.

Most programs for creating files to be used in multimedia presentations include settings and options to optimize files for publishing. Flash allows the user to choose which files type/types they want the production to use. File types that can be used for publication are .swf which exports the flash movie in a format suitable for uploading to internet, .html allows the user to export the html for the file. Gif, jpeg and png file type can be selected to export the image of the movie. Windows and Macintosh Projector option export the file for use with a projector. QuickTime movie (.qt) is an Apple files also for movies. Settings allow the user to choose which version of flash and action script should be used. Other settings allow the user to set the jpeg quality, add a password and edit sound options. Flash allows the user to create advertising animations, components for web pages, to add video and create web sites making it a popular choice to add interactivity and animation to web pages. Flash works by manipulating vector and raster graphics and supports audio and video streaming. A scripting language called Action Script is used mainly to control vector animations. There are many software applications, devices and systems that support Flash. Adobe Flash Player, available for most browsers is used to playback flash movies and animations. Mobile phones and other devices also support Flash Player to allow the use of games, web applications and movies. Flash files on the internet require a browser with Adobe Flash Player to view.
Before being uploaded to the internet web sites and web pages should be validated. Validation is the process of checking the html files for any spelling or grammar errors in the file. Browsers work by reading html files that tell the browser where and how to display text and other medium. Because browsers will accept and try to display any html file even one with problems any errors in the html language can lead to the browser not displaying the page the same in all browsers. When web pages have been validated they are ready to be uploaded to the internet. To upload a file to the internet first you must have a space on the internet to put it. There are thousands of companies offering web space both paid for and for free. Paid for hosts are generally faster, more reliable servers than free sites which can use advertising to pay for the space. Once you have somewhere to upload the web pages to you must then get it there from your computer, this is done with the use of a FTP (file transfer protocol) program. FTPs allow the user to connect to an ftp address which is the address of their space on the internet. The user must have an FTP address, sometimes called Host Name, username and password to connect to their web space. Once connected files can be uploaded by browsing to the containing folder on the computer and either dragging on to the webs pace of clicking upload. As some hosts have trouble reading files with capital letters it is important the all file names are in lower case.
Offline Delivery
Offline delivery methods include CDs, DVDs and Flash drives. CDs and DVDs have become the standard medium for delivering large amounts of data as they are cheap and reliable. Some DVDs (DVD RW) allow the user to use the disk like a drive adding and removing files as required. Flash Drives are portable drives that use flash memory to store data and allow the user to add and remove files as needed. Flash memory is used is many devices today including mobile phones, digital cameras, mp3 players and video consoles.
