FCPX Photo Depth

If your mask is not lined up with your media this could be because your media is a different resolution than your project resolution. In order to fix this make sure to compound your media by selecting the clip in your timeline, right click on it, and select New Compound Clip. The compound layer created will be the same resolution as your project. You can then apply the plugin to your compound clip and create the masks.

The masking tool uses the resolution of the project so if your media is not at the same resolution the masks will appear off target once applied. Compounding the media before applying the effect will solve this issue because it will effectively make the compound clip the same resolution as the project.

This plugin will primarily be used on photos. If you wish to apply it to a video you will need to first create a hold on the frame in which you want to apply the effect then extend the hold for your desired duration.
