Is file size a concern?
  • Yes!
  • There is always a limitation on storage, either media or hard drive

  • Consider your audience when choosing your capture size
  • Smaller movies can be played on larger screens without significant loss
  • Not the other way round
is audio necessary
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
what is feedback
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

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

  • Break the information into small segments
  • Shoot for 3 to 7 minutes each
  • Benefits

    • Shorter segments are easier for the user to remember
tips for recording
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
