Creating Online Instructional Videos

1
Creating Online Instructional Videos

• Professor Mary Sue Donsky
• Professor Adrianne Wortzel
• Karen Lundstrem, Director of Instructional
  Technology

2
Cognitive rationale for videos

• Appeals to variety of learning styles, other than
  textual print .
• For example, those with auditory learning styles
  can remember names but forget faces.
• Visual-spatial learning styles remember faces but
  forget names.
• Video has sound and visuals.

3
Say and show what you mean.

• Two tracks of learning visual-spatial and verbal
  tasks run on parallel tracks and do not interfere
  with each other because they are separate systems
  of working memory. Since the two channels are
  separate, it makes sense to teach to both of
  them.
• A video with an audio track is a good example of
  teaching to both channels.

4
Best choices for video

• Case studies Legal Assistant Studies example
• Demonstrations shoot as tight as possible to
  show the procedure
• Scenario/ slice of life

5
Problematic choices

• Talking heads (audio alone would work well and
  not take up bandwidth)
• Complicated scenes with much motion (digitizing
  the motion can cause loss of quality when video
  is compressed)
• Close-ups of BlackBoards and chalkboards. It is
  better to insert digitized type.

6
DONT

• Dont shoot in the dark. Use overhead lights if
  possible.
• Dont use digitized special effects for zooms,
  close-ups, etc. (Use the camera and take a
  close-up with the camera instead.)

7
Writing the script

• Plan each scene in advance.
• Allow room for some spontaneity, which can occur
  among cast.
• Dont plan on jumping between a wide range of
  shots (long shots, close-ups). The less motion in
  digital video, the better the quality. However,
  some cuts and dissolves can be used, so there can
  be some changes.

Digital camcorders

• Choose according to price and needs
• The JVC GR-DV2000U is just one camcorder at a
  good price and is used for demonstration purposes
  throughout this presentation. It includes an
  optical zoom, auto and manual focus, and other
  good features.

9
Wide-angle lens

• The Wide-angle lens is invaluable for capturing a
  wider area without having to pull the camera back.

10
Using the camcorder

• The Auto setting on the camcorder should be
  sufficient for most instructional videos.
• The manual setting allows for more advanced
  settings, such as changing the focus.

11
IEEE 1394

• The IEEE 1394 cable, also known as Firewire or
  Sony i.Link, will be used to connect the
  camcorder to the computer so that you can import
  the video.

12
Editing the video

• There are many choices for editing.
• Adobe Premiere and Final Cut Pro are popular
  editing tools.
• Apples iMovie is a simple, free, and fast
  editing tool. (It comes included with the Mac.)

13
Editing in iMovie

• Switch iMovie to edit mode
• Use this switch to change to edit mode
• Clips from video should be on the right of the
  iMovie screen, on the shelf.
• Copy the desired clips and Paste onto the
  timeline on the bottom of the screen.

14
Editing in iMovie (continued)

• To cut a clip
• Point the Playhead to the desired position
• Go to the edit menu Choose split video clip at
  Playhead
• Time
• 000000 minutes seconds frames
• 30 frames 1 second, 15 frames ½ second

15
Titles, Transitions and Effects in iMovie

• Use the toolbar to switch between the clips
  titles and transitions and other effects
• Choose the desired transition title or effect and
  drag it to the timeline
• Note The title and transition will take a little
  time to render
• Titles
• Choose Titles, the desired title ? type in the
  words ? drag to timeline
• If you make a mistake, reselect Title Clip, make
  changes and hit Update

16
Exporting the Video from iMovie to QuickTime

• Select File ? Export ? Export To QuickTime ?
  Format Expert Settings ? Export Movie to
  QuickTime Movie
• For High Resolution Use DSL/Cable Medium
• For Low Resolution Use Modem
• Click Save

17
Export to Digital Video for other compressions

• Select File ? Export ? Export To QuickTime ?
  Format Expert Settings ? Export Movie to DV
  Stream, Use Default Settings, Click Save

18
Compression

• Compression is used so that dial-up users can
  watch the video on the Web.
• iMovie will compress videos, but only for
  QuickTime.
• Premiere can use the Cleaner plug-in to compress
  the video in various formats.
• iMovie and Premiere already have pre-set
  compressions.

19
Compression High Resolution

• The file size with high resolution can run around
  5 Megabyte per minute.
• High resolution is for users who have a faster
  connection to the Internet.
• A good preset choice for high resolution is Video
  for LAN, cable modem, or xDSL in the Windows
  Media Export.

20
Compression Low Resolution

• The file size with low resolution can run around
  1 Megabyte per minute.
• Mainly for users with slower Internet
  connections, such as 56K modems.
• A good preset choice for low resolution is Video
  for dial-up modems or single channel ISDN for
  Windows Media Export.
