Icons and thumbnails in the main view area provide an intuitive means to navigate the network and volumes. More importantly, the thumbnails provide you with:

• Metadata corresponding to each clip, including the clip’s name, timecode, duration, and tracks.
• A playable, scrubbable representation of the clip.
• A gateway to loading the clip directly into the player.

To play thumbnail previews in the main view area:

1. Navigate to the clip of interest.

   By default, a single-image thumbnail is automatically generated for each clip in the main view area.

   
   

   (a) Current timecode (b) Duration (c) Audio track indicator (d)Video track indicator (e) Clip name (f) Scrubbable progress bar icon (g) Play/Pause icon

2. Click the progress bar to generate the playable thumbnail.

   Thumbnail generation is normally faster than real-time, depending on the network interface and processing power of the WiretapCentral server. Thumbnails are partially playable and scrubbable even when processing or downloading is not yet complete.

   The meaning of the different colours is explained below.

   Time Bar Colour	Description
   orange corkscrew	Thumbnail is not yet encoded.
   grey	A grey progress bar indicates thumbnail is being generated. Grey from start-to-finish indicates thumbnail is generated and resides in your browser’s cache.
   blue	Playable thumbnail has been generated on the server, but remains to be downloaded into your cache.
   yellow	Indicates position when playing or scrubbing.

3. Play the thumbnail by clicking the Play icon.
4. Scrub the thumbnail by dragging over the progress bar.
