Each event has a 30 second highlight video, which is stitched together from those 3 second clips plus a slideshow, including some of the pics. Zoe can be used as a regular image gallery with photos stacked together by folders, but Events groups photos by when and where they were taken. All that information is required for the advanced features of Zoe. When you use the camera in Zoe mode, every time you press the shutter key, the phone captures up to 20 full res shots and a 3 second video (1 second before you press the shutter key and 2 seconds after). HTC Zoe is more advanced than any other gallery on a phone and it was made possible by the dedicated ImageChip 2 that the One uses.
