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.
Claims15
A method comprising performing a machine-executed operation involving instructions, wherein the machine-executed operation is at least one of:
- A) sending said instructions over transmission media;
- B) receiving said instructions over transmission media;
- C) storing said instructions onto a machine-readable storage medium;
- and
- D) executing the instructions;
- wherein said instructions are instructions which, when executed by one or more processors,
- cause the one or more processors to perform the steps of:
- generating a first visual representation of a first media clip;
- generating a second visual representation of a second media clip;
- receiving input that moves one of the first visual representation and the second visual representation relative to the other of the first visual representation and the second visual representation;
- while receiving said input, automatically generating at least one of (a) a visual indication or (b) an audible indication, in response to a first point of the first visual representation becoming approximately aligned with a second point of the second visual representation;
- wherein at least one of the first point and the second point identifies an inter-clip point of interest (POI).
A method comprising performing a machine-executed operation involving instructions, wherein the machine-executed operation is at least one of:
- A) sending said instructions over transmission media;
- B) receiving said instructions over transmission media;
- C) storing said instructions onto a machine-readable storage medium;
- and
- D) executing the instructions;
- wherein said instructions are instructions which, when executed by one or more processors,
- cause the one or more processors to perform the steps of:
- generating a digital image representing an audio clip waveform;
- durably storing the digital image to a persistent storage;
- in response receiving input that requires regenerating a display of the audio clip waveform, reading the digital image from the persistent storage instead of generating a new image representing the audio clip waveform, and displaying the digital image via a user interface.
A method comprising performing a machine-executed operation involving instructions, wherein the machine-executed operation is at least one of:
- A) sending said instructions over transmission media;
- B) receiving said instructions over transmission media;
- C) storing said instructions onto a machine-readable storage medium;
- and
- D) executing the instructions;
- wherein said instructions are instructions which, when executed by one or more processors,
- cause the one or more processors to perform the step of:
- generating a single audio waveform based on a plurality of audio channels within an audio 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 audio clip based on the single audio waveform.
