  3. 3. Analog vs. Digital <ul><li>Read Articles: </li></ul><ul><li>http://www.vbrick.com/WhitePapers/WhitePaper_AnalogVsDigitalVideo.pdf </li></ul><ul><li>http://et.sdsu.edu/sphares/videowebpage/digitizing.htm </li></ul><ul><li>http://amo.net/NT/02-21-01ANADIG.html </li></ul><ul><li>http://www.recordingconnection.com/resources-t-ad.html </li></ul><ul><li>http://cameras.about.com/library/weekly/aa022501a.htm </li></ul><ul><li>http://www.loronix.com/solutions/whitepapers/analogvsdigital.asp </li></ul><ul><li>http://www.discovery.mala.bc.ca/web/schlombstj/Differences.htm </li></ul><ul><li>http://www.fiber-optics.info/articles/analog-v-digital.htm </li></ul><ul><li>http://www.vdoss.com/analogvsdigital.htm </li></ul><ul><li>http://www.marchnetworks.com/products/analogvsdigital.asp </li></ul><ul><li>http://www.eco.utexas.edu/Homepages/Faculty/Norman/ECO361N.Daily/Video.Editing/avd.htm </li></ul><ul><li>http://www.imakenews.com/designreview/e_article000099678.cfm </li></ul><ul><li>http://www.vcdhelp.com/digitalvsanalog.htm </li></ul>
  4. 4. Capturing & Converting Analog to Digital <ul><li>VHS, S-VHS, or High 8 tapes = analog signal </li></ul><ul><ul><li>Digitize using software encoder & video input device </li></ul></ul><ul><ul><ul><li>Firewire 1394 Card </li></ul></ul></ul><ul><ul><ul><li>USB </li></ul></ul></ul>
  5. 5. Digital Input to Computer <ul><li>Firewire 1394 </li></ul><ul><li>Sony’s I-Link </li></ul><ul><li>USB & converter </li></ul>
  6. 6. Digital Advantage <ul><li>No Generational Loss </li></ul><ul><li>Digital Audio (CD-quality) </li></ul><ul><li>No Static or “fuzziness” </li></ul><ul><li>Progressive-Scanned Image (not interlaced) = sharper image, no blurring </li></ul><ul><li>Can Carry Non-video Data Layers for interactivity </li></ul><ul><li>Superior Transfer of Colors </li></ul>
  7. 7. What is Compression? <ul><li>Video files are huge – need for compression algorithms </li></ul><ul><li>Most Common: </li></ul><ul><ul><li>MPEG-1 Small movie size, poor quality </li></ul></ul><ul><ul><li>MPEG-2 Decent at a reasonable file and screen size – used for CD or Web-based </li></ul></ul><ul><ul><li>MPEG-4 Near DVD quality with monitor-size movies </li></ul></ul>
  8. 8. Codecs <ul><li>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. </li></ul>
  9. 9. Codec Used for tele conf. Decent over phone lines & ISDN H.261 Used for transferring video clips from camcorder Very High Quality DV-NTCS Used with QT for both PC & MACs Good quality movie Sorenson Playback from CDs on PCs and MACs Decent movie quality at CD data rates CinePak Quality movies that will be played back from the hard drive Small enough for Web playback Indeo Typical Use Quality Codec
  10. 10. File Formats <ul><li>.AVI (Audio Video Interleave)-- Open architecture so designers can include many types of compression and playback options to suit their projects. </li></ul><ul><li>.MOV --Quicktime is cross-platform compression that retains high quality. </li></ul>
  11. 11. Streaming Video <ul><li>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. </li></ul>
  12. 12. Video Streaming Best quality generally speaking than other two types. Free player QuickTime (MOV) Creates Web-based or server-based streaming movie. Free player, encoder, & production software Windows Media Format (WMV) Creates Web-based or server-based streaming movie RealNetworks proprietary -- viewer & developer RealMedia RM Typical Use Background Streaming Type
  13. 13. Cables, Cameras, Software, More <ul><li>http://www.arp.sprnet.org/curric/video/equipment_index.htm </li></ul>
  14. 14. Common Video Capture Software Features <ul><li>Pre-record playback to screen </li></ul><ul><li>Digital Video Device Options (MS 1394, USB) </li></ul><ul><li>Compression Options (MPEG-4, MPEG-2) </li></ul><ul><li>Renaming & Save File Location Options </li></ul><ul><li>Direct Monitoring of the Recording Process </li></ul><ul><li>Playback of Recorded Movie </li></ul><ul><li>Variations on the Video Capture Theme </li></ul><ul><li>Special Effects (A/B roll, Titling, Digital Effects) </li></ul>
