Multiple choice

How has the use of motion capture technology impacted the creation of realistic and expressive character animations in films?

  1. It has led to a decline in the need for traditional animation techniques

  2. It has facilitated greater accuracy and realism in character movements

  3. It has resulted in a decrease in the quality of character animations

  4. It has contributed to the rise of deepfake technology
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The use of motion capture technology has facilitated greater accuracy and realism in character movements in films. Motion capture involves recording the movements of actors or performers using sensors, which are then translated into digital animations. This technology allows filmmakers to create realistic and expressive character animations that closely match the performances of the actors, enhancing the overall visual experience of the film.

Multiple choice
