Stitching clips

Catalyst Prepare allows you to use combine several clips to create a single clip.


  1. Select the clips you want to export in Organize or Edit mode.

    The left pane allows you to navigate the folders in your library, and the middle pane displays the contents of the selected folder

    • Click a file to select it.

    • Hold Shift and click the first and last file you want to select to select a range of files.

    • Hold Ctrl (Windows) or ⌘ (macOS) to select multiple files.

      Click the Select button to select multiple files without using keyboard modifiers.

  2. Click the Export button at the top of the Catalyst Prepare window.

  3. Enable the Use advanced settings switch in the Export pane.

  4. Select the Stitch clips check box to combine the selected clips into a single continuous clip. The order of the clips in the new clip will match the order they are displayed in Organize or Edit mode.

    If you want the new clip to include continuous timecode based on the source clips' timecode, select the Use continuous timecode check box. Clip order will be adjusted as needed, and black frames will be added between clips to ensure the timecode in the new clip is not interrupted.

    Use continuous timecode is not available if the selected clips contain overlapping timecode, if interlaced and progressive clips are selected, if clips with mixed frame sizes or frame rates are selected, or if clips with drop and non-drop timecode are selected.

    Use continuous timecode can change the order of the selected clips. For example, assume you selected the following three clips:

    • 1.mxf 00:00:10;00 - 00:00:20;00

    • 2.mxf 00:00:40;00 - 00:00:50;00

    • 3.mxf 00:00:30;00 - 00:00:40;00

    When Use continuous timecode is not selected, the clips would be rendered in the following order: 1.mxf, 2.mxf, 3.mxf.

    When Use continuous timecode is selected, the clips would be rendered in the following order: 1.mxf, 10 seconds of black frames, 3.mxf, 2.mxf.

    Use the controls in the Export pane to choose a destination and format for your exported file. For more information about the controls, please see "Exporting media from a library."
