Wondershare Filmora enables you to add as many filters or overlays as you want.
In the Media Library, select the filters or overlays that you want to add to your project.
Drag the filter/overlay from the Media Library to the Overlay Track on the Timeline. You can add background blur filters to replace the black bars if you are editing a 'portrait' clip in a 16:9 video.
2 Remove Filters/Overlays
There are two ways to remove filters or overlays from your project.
Select the target filter/overlay in the overlay track and hit Delete on the keyboard.
Right click the target filter/overlay in the overlay track and select Delete from the menu.
3 Find Filters/Overlays
All filters/overlays are albumed in the index section on the left side of the media library. Look for the filters by clicking on the albums.
4 Customize Filters
Wondershare Filmora allows you to customize effects in different ways, such as by changing the duration or effect opacity.
To change the duration
The default length is 5 seconds. But you can drag the edge of the icon to change the duration.
To change the alpha of the filter/overlay
The alpha opacity property can take a value from 0-100. A lower value makes the filter more transparent. Double click the filter to customize the alpha opacity of the filter. Then you can view how your clip looks with the filter applied to it in the Preview Window.
Note: click Reset to go back to the default alpha setting of the filter.
5 Favorite Filters/Overlays
Right click one filter effect from the list and select “Add to Favorite”. The filter effect will be stamped a heart icon. Then you can go to the Favorite category to check your favorite filter effects.
