Step-by-Step Instructions

Set Video Quality: Start by changing the video quality to 'Full' to ensure you can see all the details while editing.
Locate the Starting Point: Go to the very beginning of the video timeline where you want to start removing the background.
Select the Rotobrush Tool: In the toolbar at the top, click on the Rotobrush tool. This will allow you to isolate the subject.
Double-Click on the Subject: Double-click on the subject in the video. This action will initiate the Rotobrush tool and provide you with a working interface.
Adjust the Brush Size: Choose an appropriate brush size for your work. You can increase or decrease the diameter of the brush depending on the area you are painting.
Select the Subject: Paint over the subject using the brush. This process will highlight what you want to keep in the footage.
View Selections: By selecting the red box displayed on your screen, you can see what is included and excluded from your selection. Red areas indicate parts that will be removed.
Include/Exclude Areas: If any areas are incorrectly included or excluded, hold the Option key on Mac or Alt key on Windows to adjust the selection. Paint over the unwanted areas to exclude them and vice versa.
Analyze Footage: Once satisfied with your selections, press the Space bar. After Effects will analyze the footage and adjust the selection accordingly.
Refine Edges: If you notice issues with fine details like hair or fuzzy edges, go back to the view where you can see all adjustments. Drag down the Rotobrush tool to access the Refine Edge tool, which will help refine those tricky areas.
Finalize and Play Back: After making any necessary adjustments, allow After Effects to reanalyze the footage again by pressing Space. Once complete, return to your composition window and play back the video to see the subject seamlessly removed from the background.
