The size of the selection determines the size of the clip group. The selection can start and end on any clip boundary, empty space, or even in the middle of a clip. Selections starting or ending within a clip will separate the clip at the selection boundary when you create a clip group. Clip groups created from object-based selections include all selected and unselected clips between the first and last selected clip on the track.
The clip group appears as one clip with the clip groups icon in the lower left corner. Clip groups also appear in the Clip List.
Clip groups are created in the same timebase format (samples or ticks) as the tracks on which they are created. Multitrack clip groups can include both sample-based and tick-based tracks.
