In this tutorial we will guide you on how to change face on video using Adobe After Effects.
For this tutorial, we will be working on a free stock footage which can be downloaded from the following link:

In the video, we will add face to video using meme facial expressions. For that, we will use some of these meme faces which can be downloaded from the link below:

The idea is to keep changing the faces as the guy is surfing, starting from a concentrated meme face when he's trying to stand up on the surf board, followed by a smile meme face and lastly the rage meme face when he falls off.

Step 1 -- Adding the first meme face
So let's drag and drop the meme face layer on the top of the video footage layer. Once done, locate the concentrated meme face and make a selection around it by using the selection tool available in the toolbar menu. For the face, you can pick up the Ellipse tool to make a selection.
Step 2 -- Making the selection over the meme face
Now all you have to do is simply draw over the meme face using the Ellipse tool. After Effects will automatically mask the shape's path. You can now change the position of the shape according to the meme here. This way you can successfully add face to video.
Step 3 -- Replacing the face with the meme image
Once the selection mask is applied, reduce the size of the layer so that we can position the image on the surfer's face. To do that, make sure the image layer is selected and now press the "S" key. You should now see the scale option appearing here. Now let's change the scale to 18%. With that done let's position the meme face over the surfers face.
Step 4 -- Reducing the opacity of the image
Now we will reduce the opacity of the image so that we can see the background and position the image accordingly. For that, make sure the image layer is selected and now press the "T" key. You will now notice the opacity option appearing over here. So let's reduce the opacity to 30%.
Step 5 -- Animating the position of the meme face
Next, let's bring up the position option by pressing the "P" key. Notice that as we change the position of the image, the values here change. That means you can use these values to change the position of the image on the screen.
Moving on, now what we would need to do is animate the position of the image so that it follows the surfers face. For that, let's click on the "Position stop watch" icon
Now all you have to do is move forward in the timeline, and change the position of the image. Make sure that at each frame the image should be positioned over the surfers face.
Just keep manually moving the timeline forward, and keep changing the position of the image according to the video.
Step 6 -- Marking an end point
When it comes time to change the meme face, you need to clip the image layer timeline. For that, simply press the "Alt + ]" key.
Step 7 -- Double checking to see if you missed a spot
Now let's change the opacity back to 100 and drag the timeline forwards. See the image below, you can sometimes miss a spot when animating the image. That's why it's a good idea to keep checking back in case you might have missed a movement. Make sure you drag the image on the face properly.
Step 8 -- Changing the shape's mask path
Now let's move the timeline forwards and again let's add face to video using a different meme face.
This time, add the happy meme face. You can use the same technique that we did before for masking the meme face. That is, using the ellipse tool and drawing over the image. Remember, you can alter the anchor points of the ellipse, by simply dragging them, to better cover the image.
Step 9 -- Marking the start point
Now let's press the "Alt+[" key to crop at the current frame. This way, the image will start from this frame only.
After that, we'll use the same steps that we did before to position the image over the face and to animate it according to the video.
At the end, when the surfer is about to fall, you can add the rage meme face as well.
And that's it for how to change face on video in Adobe After Effects.
