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.
Claims20
A method comprising:
- generating a single audio waveform based on a plurality of audio channels within a media clip;
- wherein the single audio waveform reflects a combined characteristic based on audio information from each of the plurality of audio channels;
- and
- generating a depiction of the media clip based on the single audio waveform;
- wherein the method is performed by one or more computing devices.
One or more non-transitory computer-readable media carrying instructions which, when executed by one or more processors, cause:
- generating a single audio waveform based on a plurality of audio channels within a media clip;
- wherein the single audio waveform reflects a combined characteristic based on audio information from each of the plurality of audio channels;
- and
- generating a depiction of the media clip based on the single audio waveform.
An apparatus comprising:
- one or more processors;
- one or more storage media storing instructions which, when executed by the one or more processors, cause:
- generating a single audio waveform based on a plurality of audio channels within a media clip;
- wherein the single audio waveform reflects a combined characteristic based on audio information from each of the plurality of audio channels;
- and
- generating a depiction of the media clip based on the single audio waveform.
