Web Tutorial
- Events, on the right side, will lead you to multipanel pages of videos related to a particular event or phenomenon.
- Temporal View leads to a page in which you indicate the time interval of videos you want to see. Then you Submit and see the video clips.
Video Clips are displayed in chronological order, most recent first. If you cursor over a video clip, you will hear the sound associated with it. If you left click on a video you will see it at full resolution. If you left click on that larger version you will go back to the multi-tile display page. Most videos are made at QVGA (320x240), but some are made at VGA (640x480).
When you cursor over a video clip, there will be an informative subtitle just below the tiled display, with date, time, long/lat, etc, for that video. If there is a caption, it too will be displayed. If you click on that subtitle, you will get a location map if there is latitude and longitude information.
- Spatial View gives you a map, and if you left click on a pointer you will see the video associated with it.
The archive of video clips is organized in a searchable spreadsheet that includes the date/time and GPS information, the caption, group, keywords, etc.
IF YOU HAVE PERMISSION, you can use the Event Manager to select a group by which cellphones made the videos and by a time interval. (The cellphone user can also insert a group indication.). Using the list of videos at the right bottom of the Temporal display, you can delete videos (left click on the x’s), or you can choose (left click on the +’s) ones for a Custom Display. The spreadsheet listing all videos and their URL’s and content information is downloadable from the [internal] site.
