Abstract
A technique for aligning a plurality of media clips is provided. One or more intra-clip points of interest (POIs) are identified in at least a first media clip. When aligning a first point in the first media clip with a second point in a second media clip, the first point may be snapped to the second point, wherein at least one of the first point and second point is an intra-clip POI. When a snap occurs, at least one of a visual or audible indication is generated, such as a “pop” sound, a snap line, or automatically aligning the first point with the second point when the first point is within a specified number of pixels of the second point. Techniques for representing multiple channels of an audio clip as a single waveform and caching waveforms are also provided.
