In this tutorial, we will show you how to create and track the portal transition effect using Adobe After Effects. Follow these steps to achieve this impressive visual effect.

**Step 1: Prepare Your Footage**
Download the two video files provided in this tutorial or shoot your own footage. Ensure you have a shot where a person turns and looks ahead, and another shot in a different location doing the same movement.

**Step 2: Import Footage and Portal**
Import your footage and the portal image into Adobe After Effects. Create a new composition with your footage, ensuring it is set to 24 frames per second and full HD.

**Step 3: Track the Portal**
Track your portal into the scene. Use the tracking tools in After Effects to match the movement and perspective of the portal with your footage. Adjust the size of the portal to fit seamlessly into the scene.

**Step 4: Blend the Transition**
Blend the portal transition by adjusting the colors and contrast of your footage. This will help integrate the portal effect into the scene more naturally.

**Step 5: Fine-Tune the Effect**
Add additional effects such as glow or blur to enhance the portal effect. Make sure to fine-tune the timing and animation of the transition to ensure it looks smooth and realistic.
