In this blog post, we’ll guide you through the step-by-step process of cutting out the background in After Effects, sharing expert tips and techniques along the way.

Step 1: Preparing Your Project

Begin by importing your video or image file into After Effects and creating a new composition that matches your desired output settings. Right-click on your file and select “New Comp from Selection” to get started.

Step 2: Using the Roto Brush Tool

Use the Roto Brush tool (Alt/Option + W) to select the background or the subject, depending on which is easier to outline. Use the “Invert Foreground/Background” button to ensure the selection includes the part of the video you want to keep. Adjust various parameters in the Effect Controls panel to refine your selection. Step 3: Refining Your Selection

Go through your video frame by frame to ensure the selection is accurate. Once you are satisfied with the selection, click the “Freeze” button at the bottom of the composition panel to lock the selection in place.Step 4: Adding a New Background

After cutting out the background, replace it with a new one. This can be a solid color, an image, or even another video clip. Position the background layer below your subject layer and make any necessary adjustments. Adding effects like shadows or reflections can enhance the realism of the composite. Alternatively, you can make the background highly contrasting to the subject for a dramatic effect. Step 5: Preview and Final Adjustments

Use the preview function to ensure the result looks as expected. Make any final adjustments to your composition to achieve the desired effect.Conclusion
