Multiple choice

What is the most common type of special effect used in movies today?

  1. CGI

  2. Motion Capture

  3. Animatronics

  4. Practical Effects
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

CGI, or computer-generated imagery, is the most common type of special effect used in movies today. It is used to create realistic images that would be impossible or too expensive to create with practical effects.

Multiple choice

What is motion capture?

  1. A technique for recording the movements of an actor and transferring them to a computer-generated character

  2. A technique for creating realistic facial expressions on computer-generated characters

  3. A technique for creating realistic hair and fur on computer-generated characters

  4. A technique for creating realistic clothing and accessories on computer-generated characters
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Motion capture is a technique for recording the movements of an actor and transferring them to a computer-generated character. This allows the actor's performance to be used to create realistic animations.
