    15. 15. Minimal resources and expertise Accessible by most High quality possible Audio Only Can require extensive postproduction Requires ubiquitous Plugin Great resolution - can be combined with Streaming Video Slide Shows Real-time Acquisition Requires Plugin with appropriate CODEC Excellent for Screens - Bad for Motion Screen Capture Production Issues User Accessibility Quality of Delivery Method
    16. 16. Extensive resources and skills needed CD must be distributed to user Can integrate variety of media. Bandwidth less of an issue. CD-ROM Full range of video production possible Requires a tape deck Great for full motion, weak on high resolution Video Tape Design issues, variable production expertise Easy access Broad range of options, generally static Web Sites Production Issues User Accessibility Quality of Delivery Method
