Introduction

In this video tutorial, we will explore five different ways to clean up faces in videos using After Effects. These methods range from basic blurring and color correction to more advanced techniques like texture cloning and content-aware fill. By following these methods, You can enhance the appearance of facial features and achieve smoother, more polished results in your video projects.

Method 1: Blurring and Color Correction of Selected Skin Zones

The first method we'll discuss involves using blurring and color correction techniques on specific areas of the skin. This method works well for cases where there is smooth skin or when the face texture is not clearly visible. To implement this method, follow these steps:

1. Identify the areas of the face that need to be blurred or color-corrected.
2. Use the ellipse tool to Create a mask around each selected area.
3. Track the masks using the tracking feature in After Effects.
4. Create a new adjustment layer and name it "patch."
5. Copy all the masks onto the patch layer.
6. Apply the fast box blur effect to the patch layer and adjust the blur radius to match the surrounding skin color.
7. Fine-tune the patch edges by adjusting the mask feather and expansion values.
8. Optionally, add a bit of digital noise to reduce the visibility of the blurring effect.
9. Apply the noise effect and additional fast box blur effect for a more natural appearance.
10. To correct any darkened areas, duplicate the mask and apply color correction using the curves effect.

Method 2: Blurring Method with Face Tools Presets

If you have a large number of spots to blur, using the face tools presets can save you time and effort. With this method, you can create a blur map and apply it uniformly to multiple spots without tracking each one separately. Here's how to use this method:

1. Use the ellipse tool to detect the face and create a mask around it.
2. Track the mask using the detailed features tracking method.
3. Set the rest pose and extract face measurements.
4. Open the face tools library and select the desired preset from the makeup holder category.
5. Open the makeup holder composition and create a blur map.
6. Add a white circle over each spot you want to conceal.
7. Apply the fast box blur effect to each circle layer and adjust the blur radius.
8. Duplicate the circle for other spots and adjust accordingly.
9. In the makeup adjustment composition, apply the same blur effects used in Method 1.
10. Adjust the mask feather and expansion values to refine the blurring effect.

Method 3: Texture Cloning

For footage with close-up views of the face, the blurring method may not be suitable, as it can result in visible blur fragments. Texture cloning can be used as an alternative approach in such cases. Follow these steps to implement this method:

1. Duplicate the footage and name it "source."
2. Detect spots on the source footage using the ellipse tool and subtract mode.
3. Track the masks for each spot.
4. Slightly shift the patch layer beyond the mask to conceal the spot.
5. Adjust the mask feather and expansion values to make the patch edges less visible.
6. Duplicate and shift the patch layer for other spots, ensuring they don't overlap.
7. Refine the patch edges by outlining them with masks.

Method 4: Using Patch Clone Preset

To address texture shifting when the camera angle or head position changes, a patch clone preset can be used. This preset takes into account the inclination and Scale changes to maintain a consistent texture. Follow these steps to utilize this method:

1. Create a new adjustment layer and name it "patch."
2. Apply the patch clone preset to the patch layer.
3. Add the mocha effect to the original footage and track the spot to remove.
4. Save the project and export the track data.
5. Adjust the mask position, Shape, and feather values as required.
6. Specify the clone point position and adjust the size and inclination of the texture.
7. The clone texture will now seamlessly Blend into the patch area.

Method 5: Content-Aware Fill

Content-aware fill is a more complex method that can effectively remove multiple spots while preserving the skin texture. Here's how to use this method:

1. Open the content-aware fill panel and create a reference frame in Photoshop.
2. Use the healing brush and clone stamp tools to clean up the face in the reference image.
3. Save the reference image and return to After Effects.
4. Apply masks to the areas that require cleanup and add the mocha effect.
5. Track the masks using mocha and set the subtract mode for the produced mask.
6. Generate the fill layer Based on the reference frame.
7. Overlay the original footage on the fill layer, focusing on the eyes, mouth, and nose.
8. Use mocha to create X-planes for healthy skin areas and make necessary adjustments.
9. Finally, refine the results with additional methods if needed.

Pros and Cons of Each Method

• Method 1 (Blurring and Color Correction)

  • Pros: Simple and effective for minor touch-ups.
  • Cons: May not work well for footage with close-up views or noticeable texture.

• Method 2 (Blurring with Face Tools Presets)

  • Pros: Saves time by applying a uniform blur to multiple spots.
  • Cons: Limited customization options compared to other methods.

• Method 3 (Texture Cloning)

  • Pros: Works well for footage with close-up views of the face.
  • Cons: Requires more manual adjustment for each spot.

• Method 4 (Using Patch Clone Preset)

  • Pros: Maintains consistent texture regardless of camera angle or head position.
  • Cons: Requires mocha effect and additional tracking steps.

• Method 5 (Content-Aware Fill)

  • Pros: Can remove multiple spots while preserving skin texture.
  • Cons: More complex and time-consuming than other methods.

Conclusion

Cleaning up faces in videos is an essential step in achieving professional-looking results. By utilizing the various methods discussed in this tutorial, you can effectively remove imperfections and enhance the appearance of facial features. Experiment with these techniques to find the best approach for your specific video projects.
