You can export numbered image sequences in various formats using the Export Using QuickTime Conversion command. If you want to export just a part of a clip or a sequence, you can do so by setting In and Out points before exporting.
Select a clip or sequence in the Browser or open a sequence in the Timeline.
Do one of the following:
For more information about In and Out points, see Setting Edit Points for Clips and Sequences.
Choose File > Export > Using QuickTime Conversion.
Choose a location and enter a name for the file.
Note: You may want to create a new folder for the sequence of numbered image files.
Choose Image Sequence from the Format pop-up menu.
Choose a setting from the Use pop-up menu.

If none of the options you need are listed in the Use pop-up menu, see step 7.
To select custom settings, click Options.
In the Export Image Sequence Settings dialog, choose your settings, then click OK.

When you’re ready to export, click Save.
A dialog shows you the progress of the export. To cancel your export, press Esc or click Cancel.
Each file of the image sequence is named in the form of “Filename 001.ext,” where “Filename” is the name you gave, the number (001) is the number of the frame, and “.ext” is the filename extension indicating the format.
