Abstract

Some embodiments provide a method performed by a digital slate. The method receives input of a first set of metadata for a particular video clip from a user. The method receives a second set of metadata for the particular video clip from a camera as the camera films the particular video clip. The method embeds the first and second sets of metadata in a data storage structure. The method transmits the data structure for later use in matching the first and second sets of metadata with the particular video clip. Some embodiments display at least a portion of the stored metadata about the particular video clip in front of a camera at the start of the particular video clip.

creating an association between the subset of the metadata generated by the handheld device and the particular video clip.

2. The method of claim 1, wherein identifying the particular video clip as being the single video clip to which the subset of metadata pertains comprises:

extracting timecode information from the subset of metadata; and

identifying the particular video clip based on the extracted timecode information.

3. The method of claim 2, wherein the set of video clips are received from a digital tape of the video camera.

4. The method of claim 1, wherein identifying the particular video clip as being the single video clip to which the subset of metadata pertains comprises:

extracting a file name from the subset of metadata; and

identifying the particular video clip based on the extracted file name.

5. The method of claim 4, wherein the set of video clips are received from a hard disk of the video camera.

6. The method of claim 1, wherein the set of metadata is received as an XML file, the method further comprising:

parsing the XML, file to identify a plurality of subsets of metadata as pertaining to a plurality of separate video clips based on tags in the XML file that separate the plurality of subsets of metadata, each subset of metadata pertaining to a different one of the plurality of video clips;

for each subset of metadata, identifying the separate video clip to which the subset of metadata pertains; and

creating an association between each subset of metadata generated by the handheld device and the separate video clip to which the subset of metadata pertains.

7. The method of claim 1, wherein identifying the subset of the metadata as pertaining to a single video clip and identifying the particular video clip are performed by the video editing application without user intervention.

8. The method of claim 1, wherein the subset of the metadata generated by the handheld device comprises at least scene and take information for the particular video clip.

9. The method of claim 1, wherein:

the metadata generated by the handheld device prior to the camera capturing the video clip comprises at least one of a take number for the video clip, a scene for the video clip, a project with which the video clip is associated, a director of the project, and camera and sound information for the video clip;

the metadata generated by the camera during the capturing of the video comprises at least one of a timecode information and a file name for the video clip; and

the metadata generated by the handheld device after the capturing of the video clip comprises comments regarding a quality of the take to which the metadata corresponds.

10. A non-transitory machine readable medium storing a video editing application for execution by at least one processing unit, the video editing application comprising sets of instructions for:

receiving a set of metadata from a handheld device that is a separate device from a video camera, the metadata pertaining to the set of video clips and at least partially generated by the handheld device;

receiving a set of video clips from the video camera;

identifying a subset of the metadata as pertaining to a single video clip, the subset of metadata comprising (i) metadata generated by the handheld device prior to the camera capturing the video clip, (ii) metadata generated by the camera and transmitted to the handheld device during the capturing of the video clip, and (iii) metadata generated by the handheld device after the capturing of the video clip by the camera is completed;

identifying a particular video clip from the set of video clips as being the single video clip to which the subset of metadata pertains; and

creating an association between the subset of the metadata generated by the handheld device and the particular video clip.

11. The non-transitory machine readable medium of claim 10, wherein the set of instructions for identifying the particular video clip as being the single video clip to which the subset of metadata pertains comprises sets of instructions for:

extracting timecode information from the subset of metadata; and

identifying the particular video clip based on the extracted timecode information.

12. The non-transitory machine readable medium of claim 11, wherein the set of video clips are received from a digital tape of the video camera.

13. The non-transitory machine readable medium of claim 10, wherein the set of instructions for identifying the particular video clip as being the single video clip to which the subset of metadata pertains comprises sets of instructions for:

extracting a file name from the subset of metadata; and

identifying the particular video clip based on the extracted file name.

14. The non-transitory machine readable medium of claim 13, wherein the set of video clips are received from a hard disk of the video camera.

15. The non-transitory machine readable medium of claim 10, wherein the set of metadata is received as an XML file, wherein the video editing application further comprises sets of instructions for:

parsing the XML file to identify a plurality of subsets of metadata as pertaining to a plurality of separate video clips based on tags in the XML file that separate the plurality of subsets of metadata, each subset of metadata pertaining to a different one of the plurality of video clips;

for each subset of metadata, identifying the separate video clip to which the subset of metadata pertains; and

creating an association between each subset of metadata generated by the handheld device and the separate video clip to which the subset of metadata pertains.

16. The non-transitory machine readable medium of claim 10, wherein the sets of instructions for identifying the subset of the metadata as pertaining to a single video clip and identifying the particular video clip are performed without user intervention.
