by

Adobe After Effects is a robust tool used by professionals in various creative fields. A frequently performed action in After Effects is modifying or eliminating the fill of an object. In this brief tutorial, we will provide a detailed walkthrough of the process for removing the fill in Adobe After Effects.

Step 1: Import your Clip

The first step is to import your footage or the file you want to work on. From the menu bar, click on File > Import > File. Select the file and click on the Open button.

Step 2: Draw a Mask Around the Area

Next, you need to draw a mask around the area where you want to remove the fill. Select the Pen tool from the toolbar or press the G key. Draw a mask around the object you want to remove fill from.

Step 3: Apply the Fill Effect

Once the mask is drawn, select the layer and go to the Effects & Presets panel. Type Fill in the search bar and drag and drop the effect onto the layer.

Step 4: Change the Fill Colour

In the Effect Controls panel, change the fill color to match the background color of your footage. By doing this, you are effectively removing the fill from the object.

Step 5: Fine-tuning

If necessary, you can adjust the mask’s properties to better blend the object with its background. This can involve changing the mask feather, expansion, and opacity.

The following code shows how you can manually change these properties: 

        // Change mask feather
        layer.mask("Mask 1").maskFeather = [5, 5];
        
        // Change mask expansion
        layer.mask("Mask 1").maskExpansion = 2;
        
        // Change mask opacity
        layer.mask("Mask 1").maskOpacity = 80;

Conclusion

With a basic understanding of masks and the fill effect, you can manipulate your footage to achieve the desired visual result.
