Abstract

Systems and methods for linking time-based media and temporal metadata provide single command control during editing of media having associated temporal metadata. A single control enables an editor to switch between monitoring both source media and its corresponding temporal metadata and monitoring both a pre-recorded version of the media and its corresponding temporal metadata. Another single control enables an editor to start and stop the recording of a source media track and its corresponding source temporal metadata. In one application, the editing is performed for media tracks having time-based spatial metadata for playback in immersive environments with the spatial metadata defining an apparent location of sound objects within the immersive environment.

First claim

What is claimed is:

1. A media editing method comprising:
on a first media editing system:
storing a track of time-based media;
storing time-based metadata that pertains to and is temporally synchronized with the track of time-based media;

while playing back the stored time-based media track and the stored time-based metadata on the first media editing system:
receiving media and time-based metadata from a second media editing system, wherein the received media and metadata includes at least one of an edited version of the time-based media track and an edited version of the time-based metadata;
enabling a user of the first media editing system to:
actuate a first single control of the first media editing system to toggle between:
(i) monitoring playback of the stored time-based media track and the stored time-based metadata; and
(ii) monitoring playback of the media and time-based metadata received from the second media editing system; and

actuate a second single control of the first media editing system to start and stop recording the media and time-based metadata received from the second media editing system, wherein recording the media and time-based metadata received from the second media editing system overwrites a temporally corresponding portion of the media track and the time-based metadata stored on the first system.

2. The method of claim 1 , wherein the time-based media tracks of the first and second media editing systems are audio tracks; and
the time-based metadata of the first media editing systems comprise panning automation data that define an apparent location of a source of audio data on the audio track stored on the first media editing system in a space within a venue for playing back the audio track stored on the first media editing system; and
the time-based metadata of the second media editing systems comprise panning automation data that define an apparent spatial location of a source of audio data on the audio track received from the second media editing system within a venue for playing back the audio track received from the second media editing system.

3. The method of claim 1 , wherein the time-based media tracks are audio tracks and the time-based metadata comprise reverberation settings for audio data on the audio tracks in a venue for playing back the audio tracks.

4. A media editing system comprising:
a first digital audio workstation comprising a first automation system and first audio storage, the first digital audio station in data communication with a second digital audio workstation, the second digital audio workstation comprising a second automation system and second audio storage, wherein the first digital audio workstation is configured to:
receive from the second digital audio workstation an audio track and time-based metadata pertaining to the audio track;
enabling a user of the first digital audio workstation to:
actuate a first single control of the first digital audio workstation to select whether the first digital audio workstation (i) monitors playback of the audio track and the time-based metadata received from the second digital audio workstation; or (ii) monitors playback of a corresponding audio track and time-based metadata pertaining to the audio track stored on the first digital audio workstation; and
actuate a second single control of the first digital audio workstation to cause the first digital audio workstation to start recording both the audio track and the time-based metadata pertaining to the audio track received from the second digital audio workstation, wherein recording the received audio and time-based metadata overwrites a temporally corresponding portion of the audio track and time-based metadata stored on the first digital audio workstation.

5. The media editing system of claim 4 , wherein the time-based metadata stored on the first digital audio workstation and the time-based metadata received from the second digital audio workstation are panning metadata that define an apparent spatial location of a source of audio data of their corresponding audio tracks in a venue for playing back the audio tracks.

6. The media editing system of claim 4 , wherein the first digital audio workstation outputs audio data and time-based metadata that is being monitored by the first digital audio workstation to a rendering system, wherein the rendering system generates signals for a plurality of speakers to generate audio that appears to originate from a source location determined by the time-based metadata being monitored by the first digital audio workstation.

7. A computer program product comprising:
a non-transitory computer-readable medium with computer program instructions encoded thereon, wherein the computer program instructions, when processed by a first media editing system instruct the first media editing system to perform a method for media editing comprising:
on the first media editing system:
storing a track of time-based media;
storing time-based metadata that pertains to and is temporally synchronized with the track of time-based media;

while playing back the stored time-based media track and the stored time-based metadata on the first media editing system:
receiving media and metadata from a second media editing system, wherein the received media and metadata includes at least one of an edited version of the time-based media track and an edited version of the time-based metadata;
enabling a user of the first media editing system to:
actuate a first single control of the first media editing system to toggle between:
(i) monitoring playback of the stored time-based media track and the stored time-based metadata; and
(ii) monitoring playback of the media and metadata received from the second media editing system; and

actuate a second single control of the first media editing system to start and stop recording the media and metadata received from the second media editing system, wherein recording the media and metadata received from the second media editing system overwrites a temporally corresponding portion of the media track and the time-based metadata stored on the first system.

8. The computer program product of claim 7 , wherein:
the first media editing system and the second media editing system are digital audio workstations;
the tracks of time-based media are audio tracks; and
the time-based metadata of the first and second media editing systems comprise panning automation data that define an apparent spatial location of a source of audio data on their corresponding audio tracks within a venue for playing back the audio tracks.
