Apple Compressor 3 - Manual (Page 175)

• Frame Rate (fps): Use this field and pop-up menu to enter the frame rate at which you
want the still images to be created. The higher the frame rate, the greater the number
of still images created and the larger the output file. For example, if you choose 30 fps,
Compressor creates 30 still images for every second of the video clip you are transcoding.
If you choose 8 fps, Compressor creates only 8 still images per second.
• Create unique output directory: Select this checkbox to create a folder for the resulting
output files. The folder is given the same name as that of the media file, and the files
are stored inside the folder and named frame-nnn. For example, if the output filename
is test, the directory path is destination/test/frame-nnn.
If you don’t select this box, the output files are stored at the top level of your destination
folder and named filename-nnn rather than frame-nnn. Be aware that even at the slow
rate of 8 fps, a large number of files are created when you transcode to this output
format, so creating an output directory is a good way to keep your files organized.
• Add leading zeros to frame numbers: Select this checkbox to add leading zeros to the
frame number. When choosing this method, all the output files consist of multidigit
filenames, such as frame-000001 (or filename-000001 if these files aren’t being saved in
a unique output directory). If you don’t select this checkbox, each file uses a regular
filename, such as frame-1 (or filename-1 if these files aren’t being saved in a unique
output directory).
Configuring Image Sequence Settings
You use the Image Sequence output format if you want to transcode a video clip into a
series of still images.
To create an Image Sequence setting
1 In the Settings tab, do one of the following:
• Make sure that the correct setting is selected.
• Create a new setting by choosing Image Sequence from the “Create a new setting” (+)
pop-up menu.
2 Apply the setting to a job in the Batch window.
3 Make sure the resulting image sequence target is selected.
4 In the Inspector, click the Encoder tab, then choose Image Sequence from the File Format
pop-up menu.
The Image Sequence Encoder pane appears.
5 Use the Image Type pop-up menu to choose one of the following image sequence types
for the output media. For descriptions of these output types, see
