Thank you!

• Thank you for speaking at BbWorld 09. Your
  efforts are what make BbWorld an event to
  remember! A few reminders
• Weve included a two suggested slides to help you
  quickly introduce yourself and your institution.
• Clients have told us that most effective
  presentations do not focus on institution
  specifics, but rather provide best practices that
  can be applied anywhere. So we encourage you to
  refer back to the learning outcomes you provided
  in your session proposal and focus on those
  highlights.
• Your session is 45 minutes long and there will
  likely be another session in your room
  immediately following yours, so please be aware
  of the time!

Common mistakes while deploying videos in an
online environment

• Videos for online courses are often long clips of
  classroom lectures
• They often depict instructors teaching a lesson
  in a classroom
• Teaching aides (PPT, images, video clips) are
  often excluded from the video
• Videos are often encoded and delivered in a non
  accessible format.
• Files tend to be too large.

10
Why is it important to produce your videos?

• Videos produced in controlled and timed
  environment
• Instructors prepare the scripts in advance and
  record exactly what is needed
• Multimedia elements such as images, supplementary
  videos, PPT slides can be added during production
• All videos are delivered in a common format with
  similar file compression
• Online videos decrease student alienation and
  increase retention rates

• Techniques you just saw
• Utilizing external video clips and imagery from
  sources such as
• YouTube, Google video, Films.com, stock footage
  sites (Fotolia.com, iStockphoto.com etc.),
  clipart collections
• Utilizing animation and static imagery to clarify
  complex problems - Adobe Flash
• Scripted and non scripted training videos
• Mix of PowerPoint slides and chroma keyed video

13
Studio Equipment

• Camera
• Lavaliere microphone
• Green screen cloth (green screen, Datavideo or
  Reflecmedia fabric)
• Teleprompter
• Lighting
• LED preferred (cold, low energy, portable)or
• Halogen lamps (Very hot, minimum of 2000 watts,
  blinding)

Preparations - script

• Prepare the speaker in advance by telling him/her
  what to expect during the shoot
• Script should be no more than 4-5 pages long
  (10-15 minutes)
• Make sure scripts are written in a conversational
  tone
• Avoid dating the scripts (e.g. on May 2nd we will
  have an exam)

24
Preparations - speaker

• Avoid patterned shirts (checkers, stripes)
• Tell the speaker what to expect
• Relax the speaker with light conversation and
  jokes
• Make sure there are beverages available
• Always do a dry run (dont tell them its a dry
  run ?)
• Adjust the lights so they dont blind the speaker
• Observe the speaker and give him/her hints after
  the dry run

25
Video shoot

• If new presenter have someone run the
  teleprompter
• Observe the presenter and watch out for things
  such as
• Nervousness
• Overacting
• Not smiling
• Dry mouth
• Dont be afraid to call cut, even if you are
  not sure if they missed the line or not. You have
  one chance for video shoot and Premiere is not
  Photoshop.

26
Putting it all together post production

• Video production machine
• Windows machine with Matrox RT.X2 hardware
  accelerated video board
• Video storage (2-3 Terabytes, preferably in RAID
  configuration)
• Video editing software (Premiere CS3 or CS4)with
  chroma keying filter (Mattenee) and Moyea FLV
  video importer
• Adobe Photoshop, Irfanview
• Compression
• On2 Flix Pro (.Flv) and Apple QuickTime (.Mov)

27
Post production workflow
28
Gathering resources

• Stock image services such as
• Fotolia.com
• Istockphoto.com
• Photos.com
• Search engines such as
• Google
• AltaVista
• Bing?
• Other handy resources
• MS Word Clip art
• YouTube
• Films.com (Films for the Humanities Sciences)
• Your own camera and Photoshop

29
Psychology behind video production

• Alan Paivio Dual coding theory
• Information is best presented in dual channels
  Visual and verbal (audio).
• Richard Mayer expanded on this and came up with
  theory of multimedia learning.
• Refer to Nine ways to reduce cognitive load in
  multimedia learning (Mayer, R. E. Moreno, R.
  (2003) for a full list of design principles.

30
Psychology behind video production

• Avoid showing multiple visuals on the screen
  (speaker text narration). If you must, use
  with moderation.
• Avoid multiple verbal inputs (Speaker narration
  another audio channel (music, another speaker)
• Exclude extraneous materials (unnecessary
  glitter)
• Simultaneously present images with corresponding
  words/narration

31
Psychology behind video production

• Spatially connect words with images
• Avoid simultaneous textual and verbal redundancy
• Personalize your lessons/scripts
• Use clean design (simple backgrounds, virtual
  sets)
• Dont be tempted by the excessive visual effects

32
Putting it all together
33
Exporting Compressing your Footage

• Export in DV format (non compressed)
• Use the best quality when exporting
• Avoid exporting from video production software
  (Premiere)
• Use third party compression software to finalize
  your videos
• ON2 Flix Pro
• Sorenson Squeeze

34
Exporting Compressing your Footage

• Compression is an art
• Determine you audiences average connection speed
• Based on average connection speed, experiment
  with various file bitrates and dimensions

35
Exporting Compressing your Footage

• Our online videos
• FLV Hi (480x360)
• Video - ON2 VP6, VBR, 600 kpbs, 30fps
• Audio 22KHz, 64 kbps, mono
• FLV Low (370X278)
• Video ON2 VP6, VBR, 100 kpbs, 15fps
• Audio - 22KHz, 32 kbps, mono
• MOV (370x278)
• Video - H.264, 200 kbps, 15fps,
• Audio AAC, 22KHz, 24 kbps, mono
• iPhone (352x288)
