How to Rotoscope Text Behind Objects in Adobe #aftereffects

Introduction

In this guide, we will walk you through the process of placing text behind objects in Adobe After Effects using the Roto Brush tool. This technique is perfect for creating compelling visual effects where your text interacts seamlessly with the elements in your footage.

Step-by-Step Instructions

1. Copying and Pasting Your Layer

First, take the layer you wish to work on. You can use Command+C to copy and Command+V to paste the layer. This duplication will help in manipulating the object separately from the background.

2. Selecting the Roto Brush Tool

Next, find the Roto Brush tool, which is usually located in the top toolbar. This tool permits you to paint over the areas you want to select. Initially, After Effects does an excellent job detecting the edges and identifying the object you intend to select.

3. Refining Your Selection

To refine the selection, hold down the Alt (or Option on Mac) key, changing the cursor color from green to red. This action allows you to specify the areas you do not wish to include in the selection.

4. Adjusting the Timeline

Once you have a reasonable selection, locate the small blue marker on the timeline. You can click and drag this marker to extend the selection throughout the entire duration of the clip.

5. Freezing the Selection

Click the "Freeze" button to begin the freezing process. After Effects will analyze the footage frame by frame, adjusting the mask according to the initial selection. This step ensures a consistent mask through the entire clip.

6. Adding Text

Finally, you can type out your desired text. Place this text layer between the background layer and the cutout layer. Now, the text will appear behind your selected object, creating a dynamic and professional effect.
