wherein the project file generator is configured to export the supplemental material data to the project file to generate an editable video sequence file included with the editable video sequence.

9. The editing apparatus of claim 8 , wherein the editable video sequence file is configured to be edited by the video editing application by trimming at least a portion of the supplemental material data.

10. The editing apparatus of claim 8 , wherein the margin quantity setter is further configured to receive a margin quantity that identifies a time length for the supplemental material data and to automatically determine a time length of the supplemental range of the original material data based on the received margin quantity.

11. The editing apparatus of claim 10 , wherein the margin quantity setter is further configured to automatically determine the supplemental range based on the margin quantity having the time length that is specified based on a user input by a user of the editing apparatus.

12. The editing apparatus according to claim 8 , further comprising a reference range generator configured to set a reference range that identifies the time position and the time length of the editable video sequence to be edited by the video editing application.

13. The editing apparatus of claim 12 , wherein the reference range generator is further configured to automatically set the reference range for the clip of the original material data based on a user input by a user of the editing apparatus.

14. The editing apparatus of claim 8 , wherein the project file generator is further configured to generate a single editable video sequence file when the video editing application is configured to perform nondestructive editing, and to generate a pair of editable video sequence files when the video editing application is configured to perform destructive editing.

15. The editing apparatus of claim 14 ,

wherein the margin quantity setter is configured to automatically determine a pair of supplemental ranges of the original material data that consecutively precede and consecutively follow, respectively, the reference range of the original material data, and

wherein the supplemental content identifier is configured to automatically access the supplemental material data in the original material data based on the determined pair of supplemental ranges of the original material data.

16. An editing apparatus for generating and exporting a project file configured for video production, the editing apparatus comprising:

means for generating a project file that includes an editable video sequence and an editing data file that includes metadata that indicates a time position and time length of the editable video sequence referred by a video clip of original material data;

means for analyzing requested settings for the project file to determine whether an entirety of the editable video sequence referred by the video clip is included in the project file based on the time position and the time length in the editing data file;
