  1. Instructional Video Peyton R. Glore Macon State College SSCEL 10/1/05

  2. Why use video? • Show information quickly and concisely • Add a sense of realism • Teach concepts too dangerous or expensive for users to experience personally • Show places, people, animals or events that the user may never have the opportunity to see

  3. Why use video? (con’t) • Emphasizing recording video from your desktop: • Works great for demonstrating software • (Teaching or training) • Show a method or technique • Walk the user through the steps • Show the final product

  4. Who is the video for? • Determine your audience • What is their skill level? • How will they view the movie? • CD/DVD • Streaming • Download

  5. Is file size a concern? • Yes! • There is always a limitation on storage, either media or hard drive • Size should be considered if the video is to be streamed or downloaded • You don’t want to tie up the users connection all day to download a 2 minute movie

  6. File size (con’t) • Resolution, or movie size, plays a big part in the file size • How much space do you need to demonstrate your point? • What size screen will it be played back on?

  7. Resolution • Are you using a window? • Are you going to use you entire desktop? • If so, what is your current resolution? • You may want to change your screen resolution in order to capture the entire desktop

  8. Resolution • Consider your audience when choosing your capture size • Smaller movies can be played on larger screens without significant loss • Not the other way round

  9. Is audio necessary? • No, but it is nice • Benefits the user to hear the instructions while watching the actions • This is called reinforcement • Make sure you have a microphone • Set your input level (for the mic) • Turn your speakers down to reduce feedback

  10. What is feedback? • Feedback is what happens when sound being produced by the computer is being fed back into the computer • This creates a loop • Click the icon to hear the sound

  11. What are you going to cover? • Regardless of the subject matter, you will forget something • Write notes or a script! • This will ensure that you cover key points • If you normally talk fast, reading the script will slow you down

  12. What are you going to cover? (con’t) • Break the information into small segments • Shoot for 3 to 7 minutes each • Benefits • Recording shorter segments means you are less likely to make mistakes • Shorter segments are easier for the user to remember

  13. Tips for recording • Try to limit the background noise; it’s distracting to the user • Check your microphone recording level; make sure it is loud enough • Relax • Be prepared to make mistakes • No big deal

  14. Windows Media Encoder • Download the most recent version of the software from the link on the class page • Demonstrating as I record the lecture will not work, so I will talk you through the set up steps • You will be on your own to actually record

  15. WME set up Click New Session

  16. Choose the type of video you want to make and walk through the wizard

  17. You need to save the profile before you can continue Choose the type of screen capture: the entire screen or just part

  18. Modifying the profile • After you create the basic profile through the wizard, you can modify it to ensure the desired output

  19. Change the location for saving the file

  20. Modify the compression methods to make the files smaller

  21. Forcing the compression into 123 Kb per second for storage. This works well for streaming as well. This is the method I use for recording class lectures.

  22. Select audio parameters Select video parameters

  23. My application • Record lectures live in class • Insert anecdotes • Students ask questions • Online & traditional students watch lectures

  24. File size compared to movie length • 19 MB - 40 mins • 15.5 MB – 46 mins • 35 MB – 57 mins • 25 MB – 60 mins • 32 MB -56 mins • 25.5 MB -74 mins • 21 MB – 52 mins • Average 16 MB – 41 mins • Total 292 MB – 736 mins (nearly 12.5 hours!)

  25. What is in those movies? • Content varies based on subject • Longer , smaller movies audio over slides • Shorter, larger movies audio over application • Movies with lots of color and “actions” increase file size
