6 Digital Advantage No Generational Loss No Generational Loss Digital Audio (CD-quality) Digital Audio (CD-quality) No Static or fuzziness No Static or fuzziness Progressive-Scanned Image (not interlaced) = sharper image, no blurring Progressive-Scanned Image (not interlaced) = sharper image, no blurring Can Carry Non-video Data Layers for interactivity Can Carry Non-video Data Layers for interactivity Superior Transfer of Colors Superior Transfer of Colors

7 What is Compression? Video files are huge – need for compression algorithms Video files are huge – need for compression algorithms Most Common: Most Common: MPEG-1 Small movie size, poor quality MPEG-1 Small movie size, poor quality MPEG-2 Decent at a reasonable file and screen size – used for CD or Web-based MPEG-2 Decent at a reasonable file and screen size – used for CD or Web-based MPEG-4 Near DVD quality with monitor-size movies MPEG-4 Near DVD quality with monitor-size movies

8 Codecs A Codec is a coding method that facilitates the distribution and smooth playback of digital movies. This is apply when saving the movie before playback. Viewers are in stalled on the computer that employ the same codec. A Codec is a coding method that facilitates the distribution and smooth playback of digital movies.

9 Codec CodecQuality Typical Use Indeo Small enough for Web playback Quality movies that will be played back from the hard drive CinePak Decent movie quality at CD data rates Playback from CDs on PCs and MACs Sorenson Good quality movie Used with QT for both PC & MACs DV-NTCS Very High Quality Used for transferring video clips from camcorder H.261 Decent over phone lines & ISDN Used for tele conf.

10 File Formats.AVI (Audio Video Interleave)-- Open architecture so designers can include many types of compression and playback options to suit their projects..AVI (Audio Video Interleave)-- Open architecture so designers can include many types of compression and playback options to suit their projects..MOV --Quicktime is cross-platform compression that retains high quality..MOV --Quicktime is cross-platform compression that retains high quality.

11 Streaming Video Server-based streaming video begins playback as soon as viewer opens Web page. Each type of streaming video format requires a special server-based deployment, equipment, or development package. Server-based streaming video begins playback as soon as viewer opens Web page.

12 Video Streaming Streaming Type Background Typical Use RealMediaRM RealNetworks proprietary -- viewer & developer Creates Web-based or server-based streaming movie Windows Media Format (WMV) Free player, encoder, & production software Creates Web-based or server-based streaming movie. QuickTime (MOV) Free player Best quality generally speaking than other two types.
