Rolling shutter reduction

Rolling shutter distortion refers to the phenomenon where unique distortions occur in captured images when photographing or filming moving subjects.

In Catalyst Browse, you can reduce the rolling shutter distortion that occurs while shooting. Distortion from object movement will not be corrected.

To use the rolling shutter function, the stabilization metadata must be included in the clip.

  1. Click the Browse in the upper part of the Catalyst Browse window to show the media browser.

  2. Select the clip you want to correct. By clicking the thumbnail of Adjust Clip , you can check whether or not that clip includes the Rolling shutter reduction metadata.

    You can only use clips containing blur metadata.

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

    The rolling shutter reduction icon is not shown in the FTP device, the volume of the CIFS-mediated XDCAM Station, the XDCAM deck, the XDCAM drive unit, or the clip in the Optical Disc Archive volume.

      Rolling shutter reduction is only applied to distortion caused by camera movement.

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