Animation & Video

3. “Animation can enhance your multimedia applications by significantly improving learning, motivation, and attitudes and to reducing the time needed for learning. An animation gives apparent life to a graph by representing a series of images that change over time. This motion resembles a video sequence, except that an artist creates that animation with a computer tool or sequence of manual drawings rather than a film of real objects in motion. For this reason, you may find video production easier than animation.” Walsh, 1995, p. 166

4. High labor requirements tend to make animations a costly type of resource. Nontrivial animations usually require a labor-intensive process to complete. You can buy many generic animation clips on CD-ROM that will enhance multimedia presentations and productions. However, it can be difficult finding ones that meet specific needs. Some Considerations

5. More and more animations are appearing on the Internet. These can be simple animated gifs, or more sophisticated VRML sites. Just as with sound on the Internet, animation files must first be downloaded to the client computer, and then they are played. We will also examine the streaming of animation/video when we examine multimedia on the Internet. Don’t Forget the Web!

15. “Video can be the most stimulating element of multimedia because it includes the simultaneous playback of graphic images with synchronized sound. Video is the real life element of multi-media. When video is playing on the screen, a person’s attention will more likely be captivated than with the other elements. The video subtopic presents information about video techniques, compression, uses of video, computer generated effects and file formats.” Sprankle and Johnson

29. FILE FORMATS

30. Animation/VideoFiles • .AVI (PC) • .MOV (Mac) • .MPeG • .3g2 • .GIF (Office2000/XP/2003/2007 & Browsers) • .SCM (Lotus) • .SWF (Shockwave) • .RA (streaming)

31. SOFTWARE

32. Animation/Video Software • Basically there are three typesof software to: • Create/Capture • Edit • Play Note: These are not mutually exclusive.

33. Animation Creation Software GIF Construction Set - www.mindworkshop.com/alchemy/gifcon.html Kai’s Power Tools ($125) & Digital Morph($19) - Camtasia ($299)- www.techsmith.com/products/studio/default.asp

34. Purpose of this software is to capture, and compress video, and to interleave it with incoming audio. May be bundled with video capture hardware. Range in price and functionality: Mid Range – Pinnacle Studio High End – Adobe Premiere Video Creation Software

35. VIDEO COMPRESSION

36. Uncompressed video takes huge amounts of storage space. With compression, anywhere up to to 72 minutes of MPEG quality compressed video will fit on a CD-ROM. Because of low bandwidth, the Web requires “streaming” video such as RealVideo, VIVO, or Shockwave.

37. CODEC - COmpression/DECompression • Popular Codecs include Cinepack, Indeo, Indeo Interactive, RLE, and Microsoft Video. • Purpose is to eliminate redundant video artifacts/data via prediction between frames. • Keep user platform in mind when choosing a Codec.

39. High Compression

40. Consider the following example: In my computer literacy courses I have used FLOPPY.AVI to demonstrate how a floppy disk drive works. Let's see what happens if I placed this file on a streaming server… Floppy(.AVI – 8.9MB) Floppy(56k – .357MB) Floppy(LAN – 1.7MB)Floppy(28k – .214MB)

41. Consider the following example: In fall 1999, I used Distributed/Distance Leaning to teach EDC500. Since the file sizes were large, I used ScreenCam to narrate my PowerPoint presentations and placed them on a CD-ROM. I recently revised the videos using Camtasia, and, because of widespread broadband connections, I have placed these files on a Web server. Another method could be to stream them using RealPresenter. But since this software does not produce a clear screen image, I rejected it.

46. Animation Sources I have found the best source for animation to be on CD’s. This is especially true of the supporting materials that publishers are supplying with conventional textbooks. We are presently examining new literacy texts, and all major publishers are producing CD’s to accompany their texts. As may be expected, the quality of these varies greatly. One of our decisions is how to use them - optionally packaged with the books or do we place a copy on the LAN?

47. Video Sources Once again, I have found the best source for video to be on CD’s. This is also true of the previously mentioned supporting materials that publishers are supplying with their computer literacy textbooks. Since this a large market and students are already using the computer as a component of these courses, publishers have begun to produce multimedia materials on CD-ROM to supplement their textbooks. This may not be true for other subject areas.
