Alfred is a single track video editor, which represents a rearrangeable series of Clips, stacked end to end in time.

• Clip - a section of time of a media file. Clips have:

  • filename: name (url) of media
  • inpoint: start time
  • outpoint: end time
  • duration: (outpoint - inpoint)
  • description: text

• Edl - Edit Decision List. An ordered list of Clips

  • An Edl represents the entire state of the desired finished video.

• Timeline - a visual representation of an Edl

  • Clips are displayed as blocks sized proportionately to their durations, and scaled according to the Scale bar.
  • Clips can be resized as the length of the source media allows.
  • Clips can be rearranged by dragging and dropping.
  • When possible, adjacent Clips wrap to the next line in the browser depending on available space in the window.
  • the Timeline can be scaled to any size needed with the Scale bar.

• Monitor - an html <video> monitor

  • This follows the current time of the active Clip in the Timeline

• Tools - a panel of selectable Monitor controls

• TimelineTools - a panel of selectable Timeline tools

• Slider - a slideable (and throwable) input
