About the Image Sequence Encoder Pane

This section contains detailed information about the elements of the Image Sequence Encoder pane in the Inspector window. You make your image sequence settings using this pane, by either modifying an existing setting or creating a new setting in the Settings tab.

The Image Sequence Encoder pane contains the following items to help you create your image sequence output files:

  • File Extension: This field displays the TIFF file extension (.tiff) automatically after the Image Sequence output format is chosen from the File Format pop-up menu or the (+) pop-up menu in the Settings tab. Don’t alter this field. You can change the output format with the Image Type pop-up menu. This field will update automatically with your choice of output format.
  • Allow Job Segmenting: This checkbox allows you to turn off job segmenting. It is relevant only if you are using Compressor with distributed processing and with multi-pass encoding. For more information, see Job Segmenting and Two-Pass or Multi-Pass Encoding.
  • 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).
  • Scale image to preserve aspect ratio: Affects only video media using non-square pixels, such as NTSC and PAL formats, and only when you are not intentionally changing the video frame size. Select this checkbox to scale the output files to use square pixels and maintain the original aspect ratio (which results in an increase or decrease in the number of horizontal and vertical pixels). If the checkbox is not selected (the default setting), the output files use the same pixel aspect ratio and have the same number of horizontal and vertical pixels as the original video.
