Getting Started

We’ll use this clip of a truck moving on a dessert. Here, I will reveal how to remove the entire truck from the shot.

getting started with content aware fill after effects

  • Go to Window > Content-Aware Fill to launch the Content-Aware Fill panel.


  • Add a rough mask, making sure it’s large enough to cover the entire truck.


  • Then you need to track or add keyframes to the mask to follow the truck’s movement.
  • Finally, you need to change the mask tendensi to “Subtract,” else it won’t work.

Disappearing Act

  • You’ll now notice a preview of your mask in the “Fill Target” segment of the Content-Aware Panel. The Fill Target shows you the region that will be analyzed. You can likewise see that the empty area has a red outline.


  • Under the Fill Objek is the “Alpha Expansion,” which enables you to extend the kawasan to be analyzed.
  • You have three different “Fill Method” options. “Object” is the default one and is exceptional at removing moving objects. The next one is “Surface,” used for static shots and kondominium surfaces. “Edge Blur” is the last one and works excellently on stationary objects and surfaces that lack textures.


  • “Range” allows you to specify if you want the Content-Aware Fill to work on the whole composition or just the selected area.
  • In this example, we’ll apply the Object method, and the range will be the entire composition since the shot is of short duration.
  • Click on “Generate Fill Layer” to begin the process of object removal.
  • After Effects will examine the shot, render a fill layer, consequently place a PNG sequence in the composition, and fill up the missing areas in your shot.
  • Once you have followed all these steps, you would no longer see the unwanted objects in your scene.

Reference Frames

At times, when Content-Aware Fill isn’t giving you the kind of results you desire, perhaps using a Reference Frame will provide you with better results. Creating a reference frame will help the algorithm learn how the shot should look like.

  • When you select Create Reference Frame, After Effects directly exports a frame from your video to Photoshop.
  • You would then be able to use the Clone-Stamp tool to fill in the removed area. Save and close the image in Photoshop. This reference image will then be imported back into After Effects and into your composition automatically.
  • Content-Aware Fill will now consider that reference image while creating the fill throughout the video.

  • It is always acuan to remove intricate objects using different masks. For instance, separate a person walking and his shadow — mainly if the shadow movement is quite different.
  • Smaller masks are quicker to render.
  • Fill layers are PNG sequences that may take substantial drive space, so make sure to remove the ones you won’t use.
  • Feather the mask if you see borders in your fill layer. The subsequent mask will provide you with a fill layer with softer edges.
  • You can make selections using a mask, roto brush, eraser tool, or keyframing.
  • High-resolution files such as UHD or 4K take more time to render than HD or SD. So, if your clip is longer than 10 to 15 seconds, I suggest splitting the clip into shorter clips and then applying the content-aware fill.
  • The higher RAM you install, the greater the performance.
