Step 3: Mask the Unwanted Objects

• Ensure that you close the mask shape.

Step 4: Adjust Mask Properties

• Expand the layer in the timeline by twirling it open.

• Repeat this process until you reach the end of the footage, adding keyframes for each adjustment.

Step 6: Use the Content-Aware Fill Panel

• Save your project (Cmd/Ctrl + S).
• Return to the Mask settings and ensure the mask is set to ‘Subtract’.
• Open the Content-Aware Fill Panel.
• Set the Fill Method to ‘Object’.
• Change the Range to ‘Work Area’ (or keep it at Entire Duration if you didn't set the Work Area).
• Click on ‘Generate Fill Layer’ and wait for After Effects to analyze the footage.
• The masks should fill in automatically.

Step 7: Preview Your Work
