Wrinkle & Basic Blemish Removal with Mocha AE and After Effects CC

mocha_AE_logo

Beauty retouching has evolved throughout the ages. First, we had make up artists who would do their best to mask and cover various blemishes. Over time, it became possible to retouch photographs by hand to cover any blemishes the makeup artist was not able to clear. Now, we are not only able to retouch images, but high resolution video itself. Right now there is a growing niche market of beauty retouchers and artists taking on the role of a “digital make up artist,” retouching and removing various wrinkles, blemishes, shine, and more. I will show you how to remove wrinkles and basic blemishes using a combination of Mocha AE and After Effects CC in three easy steps:

– Create a Main Track in Mocha

– Create cover layers in Mocha

– Export and Composite in After Effects

 CREATE A MAIN TRACK IN MOCHA

With your footage in Mocha, first look at your subject and decide where exactly your will be focusing.

Looking at my subject, I can see she has some general light blemish marks along her left cheek. Additionally, as she scrunches up her mouth she creates a dimple in the corner of her mouth which will act as a good “wrinkle” example for us, as well to show the range of this techniques use.

The goal here is to smooth out that dimple in the corner of her mouth while also blending away those light blemishes along her cheek. In the footage, she keeps her head in that general direction. This allows certain features of the face to be ideal for motion tracking, such as the eyebrows, chin, and nose (the ear and hairline is also good, however, in this sample the hair is covered by the ear and the wind is blowing her hair around her forehead, making these options not possible). Using the X spline tool, create a generic shape around the eyebrows, chin, and nose and TRACK FORWARD.

You can label that layer in your LAYERS PANEL as MAIN TRACKER to help stay organized. We will not create an additional layer that we can animate over the course of the clip while linking it to the Main tracker for general motion.

CREATE COVER LAYER IN MOCHA

The Main track is to capture the overall movement of the camera and of subject’s head and face. Throughout the clip, the subject moves their mouth slightly with a few other facial muscles contorting. We need to create a cover layer that will focus on the wrinkle and blemish area while also remaining flexible as the subject contorts their face and mouth. From here, I am going to create a cover layer focusing on the areas mentioned.

The mask at first seems a bit jagged, so highlight all the points, right click, and go to POINT > SMOOTH

Now, make sure you have that new cover layer highlighted and go to LINK TO TRACK > MAIN TRACKER. This will now link the cover layer to the main tracker allowing it to follow along with the camera and facial movement. For the fine tuning of the face contorting throughout the clip, scrub through the footage. As you see the mask intersecting with areas of the mouth and her movement, grab the points and adjust accordingly. This will create a keyframe on the timeline indicating that the mask will be in that form at that exact point on the timeline. Continue to scrub through the footage adjusting all remaining points as needed.

Once you think you are finished, let the footage playback a few times and watch the facial movements against your keyframed layer to make sure everything meets your expectations.

EXPORT AND COMPOSITE IN AFTER EFFECTS

Once you are ready to export the cover layer, go to EXPORT SHAPE DATA located in the lower right of the program window. At the pop up window choose COPY TO CLIPBOARD.

Back in After Effects, create a new Adjustment Layer (CMD + OPT + Y) and then paste the mocha mask shape onto the adjustment layer by going to EDIT > PASTE MOCHA MASK.

With the cover layer now composited on top of your source clip in After Effects, go ahead and add a BOX BLUR to the Adjustment Layer. Increase the BLUR RADIUS to 10 and open the mask settings and feather the edges to about 15.

And now take a look at with the cover layer on and off

You can see the blemishes have been removed and there is a general smoothness to the dimple around her mouth as well. As you increase the BLUR RADIUS, you can further smooth out the wrinkle. Be warned that increasing this too much will distort the image and will not look realistic whatsoever. You’ll need to use finesse. In another lesson, I will go into more detail on how to eliminate glaring blemishes, scars, and birth marks.
