Abstract

A computer implemented method and system provide for automatic selection and extraction of metadata and media content from projects in a craft tool. Automated identification, classification and management of such metadata and content is provided using including techniques such as pattern recognition for audio and visual content. The automatic tracking and centralised storage of metadata and content for compliance purposes can be facilitated, and can enable querying of organized metadata stored in a central database. In an example, metadata and media content are extracted automatically from a project in a craft tool at a client system and are forwarded to a host system for the creation of a cue sheet including timings for media files from timing metadata in a project file to create the timings on the cue sheet.

Claims

1. A computer-implemented method of generating a metadata record representative of media content from at least one sequence of at least one project from at least one craft tool, the method comprising steps, performed by at least one first computer system, of:

extracting stored metadata for a project defined by the craft tool and adding the extracted metadata to a project file, the craft tool being a computer-implemented tool for audio and/or visual editing and being operable to define a project using media content and metadata for the project, wherein the media content is stored in media items;

extracting media content for at least one stored media item of the project and adding the extracted media content to the project file; and

outputting the project file,

wherein the extracted media content is processable to generate a representation of the extracted media content, and wherein the representation includes a fingerprint of the extracted media content.

2. The method of claim 1, further comprising:

performing pattern recognition with respect to stored reference data using the representation of the extracted media content to determine metadata identifying the extracted media content; and

generating an output comprising the extracted metadata and the determined metadata identifying the media content.

3. The method of claim 2, wherein:

generating the output includes transmitting the extracted metadata and the representation of the extracted media content to at least one second computer system.

4. The method of claim 3, comprising the at least one second computer system performing pattern recognition at the second computer system with respect to stored reference data using the representation of the extracted media content, and where a match is not found, updating the stored reference data.

5. The method of claim 2, wherein:

the representation of the extracted media content is a Fourier transform of the extracted media content; and

the stored reference data comprises Fourier transforms of respective reference works associated with metadata identifying the reference works.

6. The method of claim 1, further comprising:

transmitting the project file to at least one second computer system configured to perform pattern recognition with respect to stored reference data using the representation of the extracted media content to determine metadata identifying the extracted media content and generate a metadata record file comprising the extracted metadata and the determined metadata identifying the media content.

7. The method of claim 6, further comprising encrypting the project file prior to transmission to the at least one second computer system.

8. The method of claim 6, wherein:

the representation of the extracted media content is a Fourier transform of the extracted media content and wherein the extracted media content is processable to generate a Fourier transform of the extracted media content;

the stored reference data comprises representations of respective reference works associated with metadata identifying the reference works; and

the stored reference data comprises Fourier transforms of respective reference works associated with metadata identifying the reference works.

9. The method of claim 1, wherein the stored media content comprises at least one of audio, text, image and video.

10. The method of claim 1, wherein the metadata includes metadata identifying a rights holder in respect of the stored media content.

11. The method of claim 1, wherein the representation of the extracted media content includes a representation of one or more items selected from the group consisting of:

faces, images, voices, moods, product placement opportunities, a plurality of tracks of a project, and a complete project.

12. The method of claim 1, further comprising generating a metadata record comprising a cue sheet.

13. A non-transitory computer-readable storage medium comprising program code forming a data extraction module for processing a project defined by a craft tool implemented on at least one computer system that comprises a processor and storage, the data extraction module being executable to:

extract stored metadata for the project defined by the craft tool and add the extracted metadata to a project file, the craft tool being a computer-implemented tool for audio and/or visual editing and being operable to define a project using media content and metadata for the project, wherein the media content is stored in media items;

extract media content for at least one stored media item of the project and add the extracted media content to the project file; and

output the project file;

wherein the extracted media content is processable to generate a representation of the extracted media content, and wherein the representation includes a fingerprint of the extracted media content.

14. A system comprising at least one computer system comprising a processor and storage, wherein:

the at least one computer system stores program instructions executable to implement a craft tool, the craft tool being a computer-implemented tool for audio and/or visual editing operable to define a project using media content and metadata for the project, wherein the media content is stored in a plurality of media items;

the at least one computer system stores program instructions executable to implement a data extraction module operable to;

extract stored metadata from the project sequence and add the extracted metadata to a project file;

extract media content for at least one stored media item of the project sequence and add the extracted media content to the project file; and

output the project file,

wherein the extracted media content is processable to generate a representation of the extracted media content, and wherein the representation includes a fingerprint of the extracted media content.

15. The system of claim 14, further configured:

to perform pattern recognition with respect to stored reference data using the representation of the extracted media content to determine metadata identifying the extracted media content, and

to generate an output including the extracted metadata and the determined metadata identifying the media content.

16. The system of claim 14, wherein:

the stored media content comprises at least one of audio, text, image and video,

the metadata includes metadata identifying a rights holder in respect of the stored media content and the system is operable to generate a metadata record in the form of a cue sheet;

or

the representation of the extracted media content includes a representation of one or more items selected from the group consisting of;

faces, images, voices, moods, product placement opportunities, a plurality of tracks of a project, and a complete project.
