This is the result we will create, a subject that remains sharp and bright, while the background is softly blurred and slightly dark, just like it was recorded with a portrait lens. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. The rotoscoping result can be refined in the Effect Controls. In this episode, we will clean up the edge of the cut, then use it for the popular portrait effect in interview videos.
Prepare the interview composition like in the previous episode. Duplicate the footage into the subject, then separate it with rotoscoping using a green screen on the body and a red screen on the background.
Open the Effect Controls for the subject. There is the Roto Brush and Refine Edge effect. Fill the Feeder 3 so the edge is not sharp like a paper cut, then Shift Edge minus 10 to move the edge slightly inward, removing the remaining bright background from the window. Contrast 20 makes the edge transition more defined without becoming harsh.
Reduce Shutter 30 calms the shaking edge from frame to frame, a common issue with automatic rotoscoping.
Select the bottom footage and apply Gaussian Blur with bluriness 25. The background is softly blurred, while the subject on top remains sharp. This is the effect of a shallow depth of field.
Add Lumetri Color to the bottom footage with exposure minus 0.5 so the background is slightly darker. On the subject, add exposure plus 0.2. The viewer's eyes immediately focus on the subject.
Rotate the preview. The subject is bright and sharp in front of the blurred background. Without Refine Edge, the edges of the hair and shoulders will look rough against the blurred background.
Done. We have used Fader, Shift Edge, Contrast, and Reduce Shutter on Roto Brush and Refine Edge, then created the portrait effect with Gaussian Blur and Lumetri. In the next episode, we will perform manual rotoscoping using a tracked mask. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films?
