Why do it this way?

  • Virtual worlders are already familiar with making videos in virtual worlds.  
  • And we are familiar with editing those videos in Shotcut
  • We will make our podcasts in virtual worlds, since we are familiar with meeting there.
  • And we already know educators who will collaborate with us on the project.
  • Collaboration is the secret sauce for educators in virtual worlds.

You need Shotcut installed

Detailed steps

  • Start as you would to edit the video:
  • Drag/drop the video file into the source panel (upper left)
  • Put the cursor where you want to start the sound clip.
  • Press i (for in) on the keyboard.
  • Put the cursor where you want to stop the sound clip.
  • Press o (for out) on the keyboard.
