Video Filter Edit Tool


This tool allows you to modify the settings of an applied filter. It is opened by clicking the Filter Edit Tool button on the Video Filters panel. When you open this tool and the selected Media Item has no current filter, the edit controls will be disabled (grayed out). In this case, click the Add Filter button on the toolbar to create a new filter for the Media Item. Filter changes are saved when you save the Media List.

The best way to use this tool is to apply it to a loaded Media Screen and view the changes to a live video as you modify the Filter settings.
