Stabilizing clips

Catalyst Prepare allows you to use metadata from clips to stabilize the image.


  1. Click the Organize button at the top of the Catalyst Prepare window to view the Media Browser.

  2. Select the clip you want to stabilize. An on a thumbnail indicates a clip that contains stabilization metadata.

    The stabilize icon is not displayed for clips on FTP devices, XDCAM Station volumes via CIFS, XDCAM decks, XDCAM Drive units, or Optical Disc Archive volumes.

    For information about camera settings for enabling stabilization using metadata, please see Information on Software Applications.

    Clip stabilization is not supported when changing camera settings or detaching the lens during clip recording.

  3. Perform any of the following actions to display the Correct clip workspace:

    • Click the Stabilize button at the bottom of the Catalyst Prepare window.

    • Right-click the clip in the Organize pane and choose Stabilize clip from the shortcut menu.

    The Stabilize button is not available when multiple clips are selected.

    When the Catalyst Prepare window is resized, the Adjust color , Lens breathing compensation , and Stabilize clip buttons are available in the Adjustments menu .

  4. Use the Correct clip workspace to preview and adjust stabilization settings for the selected clip:

    1. Set the Mark In/Out points to indicate the portion of the clip you want to correct. For more information, see "Marking in and out points for playback."

    2. Choose a Stabilization mode setting:

      • Select the Auto button in the Inspector to adjust stabilization automatically.

        The graph below the preview helps you visualize the stabilization. Please note that the graph is not displayed when multiple clips are selected.

        • The curve (1) represents the amount of stabilization that is required based on clip analysis.

        • The solid line (2) represents the Auto cropping amount after analysis.

        • The dashed line (3) represents the Maximum cropping amount setting.

        Click the Graph button to customize the display of the graph:

        • Turn on the Scale graph to clip switch to adjust the vertical scale of the graph to match the current clip.

        • When Scale graph to clip is off, you can drag the Graph scale slider to set the vertical scale of the graph.

        Description

        Auto cropping amount

        After the clip is analyzed, this indicator represents the amount of cropping that will be used to stabilize the clip.

        Maximum cropping amount

        Drag the slider — or the dashed line (3) in the graph — to set the amount of cropping that can be applied to stabilize a clip.

        • If the automatic adjustment results in a clip that is larger than the maximum cropping amount, the Maximum cropping amount will be used.

        • If the automatic adjustment results in a clip that is smaller than the Maximum cropping amount setting, the automatic adjustment results will be used.

        This setting is persisted when changing the selected clip or exiting the Correct clip workspace.

        When stabilizing a clip using a Maximum cropping amount setting that is too large, clips with significant camera shake may exhibit a black border around the frame. We recommend using a setting that is close to the default cropping size in manual mode. To check the default manual cropping size, click the Manual button or double-click the Cropping amount slider handle to reset the setting to its default.

        Source resolution

        Displays the dimensions of the source media before cropping is applied.

        Corrected crop resolution

        Displays the dimensions of the stabilized frame after cropping is applied.

        Minimum crop resolution

        Displays the minimum dimensions of the stabilized frame based on the Maximum cropping amount setting.

        If source clips captured with Active image stabilization mode exhibit blurring when using Auto mode, choose Manual mode and decrease the Cropping amount setting.

      • Select the Manual button if you want to adjust stabilization settings:

        The graph below the preview helps you visualize the stabilization. Please note that the graph is not displayed when multiple clips are selected.

        • The curve (1) represents the amount of stabilization that is required based on clip analysis.

          Click the Graph button to customize the display of the graph:

          • Turn on the Scale graph to clip switch to adjust the vertical scale of the graph to match the current clip.

          • When Scale graph to clip is off, you can drag the Graph scale slider to set the vertical scale of the graph.

        • Region (3) indicates the minimum cropping amount without displaying black borders around the frame.

        This setting is persisted when changing the selected clip.

        When stabilizing a clip using a Cropping amount setting smaller than the default value, clips with significant camera shake may exhibit a black border around the frame. We recommend using a Cropping amount setting that is close to the default value. You can double-click the slider handle to reset the setting to its default.

        Source resolution

  5. Click the Analyze button to analyze the selected clip and update the preview to show the stabilized clip.

    After analysis, the Summary section of the Info panel displays the corrected crop resolution.

    If you change the selected clip, the preview will indicate that the clip has not been analyzed. Click the Analyze button at the bottom of the workspace to analyze the selected clip and update the preview to show the corrected clip.

  6. Click the Before/After button at the top of the video preview to choose a preview mode so you can compare your original and stabilized video before applying the changes, and then use the transport controls above the timeline to preview the clip.

    • Before: the clip is displayed in its original state.

    • After: the cropped and stabilized clip is displayed.

    • 2 Up: two full frames are displayed in a split-screen view with the original video on the left and the stabilized video on the right.
