How to Remove Unwanted Objects from Video in Adobe After Effects
Education
Introduction
Removing unwanted objects from videos can be a daunting task, but with Adobe After Effects, it can be accomplished effectively using the Pen Tool and the Content Aware Fill feature. In this guide, we will walk you through the essential steps needed to neatly mask an object and remove it from your footage.
Step 1: Create a Selection with the Pen Tool
Select the Pen Tool: Begin by using the Pen Tool to carefully create a selection around the object that you want to remove from the video.
Layer Panel Settings: In the Layers panel, set the mask to subtract. This ensures that the area inside your mask is what will be affected by your edits.
Add Keyframes for Animation: Click on the stopwatch icon next to 'Mask Path' in the mask settings. This allows you to set keyframes, enabling you to adjust the mask as needed throughout the timeline.
Adjust the Mask: As you progress through the video, make adjustments to the mask so that it follows the object smoothly. Setting the mode to 'None' while you do this can help you see your edits clearly.
Step 2: Implement Content Aware Fill
Return to Subtract Mode: Once you are satisfied with the mask outline, switch the mask back to subtract mode.
Access Content Aware Fill: Navigate to the Content Aware Fill section of After Effects.
Generate Fill Layer: Click on ‘Generate Fill Layer’. This action will analyze the surrounding footage and create a new fill layer that fills the area where the unwanted object was masked out.
Review Your Work: A new fill layer will appear in your layers panel. The quality and effectiveness of the removal will depend on the selection made and the specific footage.
Adjust as Necessary: You may need to make further adjustments depending on your footage and the length of the area you are trying to cover.
By following these steps, you can efficiently remove unwanted objects from your video, resulting in a cleaner output that enhances the overall quality of your project.
