Based on this, attribute data such as UMID data, V / A_C data and EM data stored as KLV data (V) is extracted.
Step ST3:
The CPU 18 generates image data to be displayed in the file attribute display field 42 shown in FIG. 5 that displays the attribute data extracted in step ST2, and outputs the image data to the display 16 via the interface 12.
Thereby, the attribute data such as the UMID data, V / A_C data and EM data extracted in step ST2 are displayed in the file attribute display column 42 of the GUI screen 30 shown in FIG. Is displayed.
[0032]
Step ST4:
The CPU 18 generates an image signal of an image to which the EM data in the file data FILE_1 to FLIE_N input from the external devices 3_1 to 3_N connected in step ST2 is based on the EM data extracted in step ST2. Output to the display 16 via the interface 12.
As a result, a preview of the image specified by the EM data is displayed in the preview column 43 in FIG.
When a plurality of file data are stored in the external devices 3_1 to 3_N connected in step ST2, the CPU 18 displays the preview of the file data specified by the user.
[0033]
Step ST5:
The CPU 18 determines whether or not the import instruction button 48 shown in FIG. 5 has been designated by the operation of the operation unit 14 by the user. If it is determined that the import instruction button 48 has been designated, the process proceeds to step ST8. If not, the process proceeds to step ST6. Return.
Step ST6:
The CPU 18 connects the portion (range) defined by the IN point and the OUT point specified by the columns 61 and 62 in the file data FILE_1 to FILE_N being previewed to the preview column 43 shown in FIG. Input from 3_N (import).
[0034]
Step ST7:
The CPU 18 converts the data input from the external devices 3_1 to 3_N in step ST6 into a native format for non-linear editing (Non Linear Edition) to generate clip data. The clip data is given the name input in the clip name input field 47 shown in FIG.
The CPU 18 stores the clip data in an editing memory (not shown).
Thereafter, the CPU 18 reads and uses the clip data in the editing process.
Step ST8:
The CPU 18 determines whether or not a predetermined end condition is satisfied. If it is determined that the predetermined end condition is satisfied, the process ends. If not, the process returns to step ST4.
[0035]
As described above, in the editing device 4, in addition to the file name (NAME), size (SIZE), and update time (TIME) of the file data input from the external devices 3_1 to 3_N designated as the connection destination, The file attribute display field 42 shown in FIG. 5 showing the presence / absence of UMID data and the presence / absence and number of V / A_C data and EM data obtained by parsing the file data is automatically displayed.
Therefore, it is possible to easily determine whether or not the content to be imported is included in the file data only by looking at the file attribute display column 42.
Further, according to the editing device 4, the user can easily grasp the progress of the image being previewed in the preview column 43 based on the preview progress display column 44.
Further, the mark EM_M is displayed on the time axis 60 in the preview progress display column 44, and the mark 65 is displayed on the preview screen of the image to which the EM data is added. Can be easily identified.
Further, according to the editing device 4, a preview of the file data displayed in the file attribute display column 42 can be displayed in the preview column 43 by a simple operation, and the user can input the IN point and the OUT in the columns 61 and 62 shown in FIG. By specifying a point and subsequently specifying the import instruction button 48, clip data can be automatically generated.
