Visual Effects (VFX) are used in almost every movie, game, and TV show today, they bring imagination to life and make impossible scenes feel real. But to create amazing VFX, artists must learn the basics first—starting with rotoscoping and compositing.

Whether you dream of working in Hollywood or joining a creative studio in India, these two skills are the building blocks of VFX. If you’re planning to join an animation degree course or looking for a VFX course in Odisha, this guide is just for you!

What is Rotoscoping?

Rotoscoping is the process of tracing objects or people in live video, frame by frame. This helps remove or separate them from the background.

Basic Steps of Rotoscoping:

Start with a clean background that has no people or motion.
Add onion skinning to view multiple frames at once.
Apply motion tracking to keep the movement smooth.
Create mattes for tricky parts like hair, glass, or smoke.

This technique is important when green screen (keying) doesn’t work well. Rotoscoping helps create clean masks to blend real video with digital effects and break your object into small, simple shapes and it gives you more control.

What is Compositing?

Compositing is when you combine different visual elements into one final scene. For example, placing an actor in a digital background or adding smoke and fire to a battle scene.

Main Compositing Techniques:

Layer-based compositing: Combine multiple video layers with blending effects.
Keying: Remove green or blue screens.
Matte painting: Add new digital backgrounds.
Matchmoving: Make CGI match the movement of the real camera.
Color grading: Match lighting and colors between layers.
Adding effects: Insert fire, rain, fog, or explosions.

These techniques make the final shot look natural and believable.
