You can encode clips into QuickTime. You can export files of almost any size and, depending on the QuickTime file format, you can apply variable compression rates to create video files with a suitable trade-off between image quality and file size.

If your video clip contains audio that extends before or after the video portion, ensure that the Consider Audio Head/Tail button is enabled. See Audio Preferences.

You can export QuickTime video files by adding them to the render queue and rendering them as a background process. When you export video files, the following frame size requirements must be met.

When exporting QuickTime MPEG-4 files, ensure that you export the clip in Progressive mode, rather than Interlaced mode. QuickTime MPEG-4 clips exported in Interlace mode are not supported properly on Mac computers.

You can also use Cleaner XL to export video file formats. The advantage of using Cleaner XL rather than native video export is that it offers a much broader range of export formats and compression options. Its export process also runs on a separate computer, which is dedicated to the encoding process. See Exporting Media to Cleaner XL for Encoding.

To export a video file:

1. Open the clip library containing the clip that you want to export.
2. Select the clip.
3. Click Export Image.

   The Export Image menu appears.

4. In the file browser, browse to the directory where you want to export the clip.
5. From the File Format box, select QuickTime.

   
   

6. Optional: Change the default file extension.
7. To change the name of the exported image file, enter a name in the Name field.

   
   

   NoteTo avoid filename compatibility issues upon export, underscores will be substituted in your filename in place of any of the following characters: ` # ~ @ $ % ^ & * ( ) [ ] { } < > \ | / ! ? , ; : ' "
8. Select a video codec. If you are using DVCProHD resolutions, note that the available progressive framerates (not fields) are listed for each.
9. Select a predefined codec profile for the selected video codec. See Working with Codec Profiles.
10. If an audio track is available, enable Include and select an audio codec.

    AudioDesk settings are always applied to the exported audio track.

11. Select a predefined codec profile for the selected audio codec. See Working with Codec Profiles.
12. In the Frame/Clip box, specify whether you are exporting a single frame or an entire clip.
13. To resize the exported video, use the resizing options, such as Width, Height, and Fit Method. See Resizing Group.
14. To apply gamma correction or to use a predefined LUT, load it using the Colour Correction Type box.

    
    

    When exporting files to a Mac, use Convert 2.2 to 1.8 for gamma correction.

    See Applying a LUT on Import or Export.

15. Select an option from the Add to Queue box.

    
    

    Select:	To:
    Add to Queue	Add the job to the queue.
    Add to Queue & Execute	Add the job to the queue and execute it automatically. If there are any jobs in progress, this job (and any others already added to the queue with the Add to Queue & Execute option) is triggered upon the completion of its predecessor.

    Selecting an option from the Add to Queue box adds the export job to the Background Import/Export Queue. Video files can only be exported as a background process.

16. Swipe left or right to display the Import/Export Queue menu.
17. Select the files in the export queue that you want to export, and then click Execute Selected.

    
    

    The selected clips are exported. When the export is finished, you are returned to the clip library.
