CGI (Computer-Generated Imagery): 

creating 3D or 2D images and animations using computer software. that are seamlessly integrated into live-action footage.

Compositing: 

This is the process of combining multiple visual elements into a single image or scene. involves layering video, images, and CGI to create a cohesive final look.

Matte Painting: 

Digitally or traditionally created landscapes or sets used to extend physical sets or create entirely imaginary settings.

Motion Capture (MoCap): 

Actors' movements are recorded using sensors or cameras to animate digital characters. This is widely used for creating realistic character movements.

Simulation Effects: 

This includes creating dynamic elements like fire, smoke, water, explosions, or particle systems. Physics-based simulations help in achieving realistic behavior.

Match-moving/Tracking:

It involves tracking camera movement or object movement in a scene for elements align perfectly with the motion of live-action footage.
