Rotoscoping, also known as roto, is an animation technique in which animators trace a projection of live-action footage frame by frame to produce realistic character movements. In early animated films, animators traced over glass panels to create 2D animation with characters that moved like real people. The technique was especially useful for creating lively dance sequences.

Rotoscoping was pioneered by animator Max Fleischer who developed the rotoscope tool to create the animated character Koko the Clown in the early 1900s as part of his *Out of the Inkwell* series. Fleischer captured footage of his brother, Dave Fleischer, performing as Koko the Clown. Fleischer used the live-action footage of Koko the Clown as a reference to create the animated character. Fleischer also used this technique to make the character Popeye in 1929, Betty Boop in 1930, and the animated *Superman* film series in 1941.

When Fleischer’s patent for the rotoscope tool expired in 1934, Walt Disney <a href='https://masterclass.com/articles/how-to-create-an-animatic-for-your-next-film' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/how-to-create-an-animatic-for-your-next-film","linkCopy":"Animation","category":"automated-link"}' automatic='true'>Animation</a> Studios adopted the technique. For films such as *Snow White and the Seven Dwarfs* (1938), *Cinderella* (1950), *Alice in Wonderland* (1951), and *Sleeping Beauty* (1959), live actors performed scenes that animators used as references when rotoscoping. 

Today, filmmakers use computer programs like Rotoshop, Adobe After Effects, and Adobe Photoshop to rotoscope digitally. Animators use rotoscoping to create animated films and video games, and filmmakers can create visual effects (<a href='https://masterclass.com/articles/how-visual-effects-work-in-film' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/how-visual-effects-work-in-film","linkCopy":"VFX","category":"automated-link"}' automatic='true'>VFX</a>) for live-action films with the help of mattes. Some anime artists manually trace live footage frame by frame to create realistic anime characters. 

Rotoscoping requires attention to detail and is time-consuming. Other drawbacks include the animation timeline, which depends on the live footage production schedule. Also, the footage captured can limit the movements and actions the animators can use for characters and sequences.
Some well-known feature films made with the rotoscoping process include:

1. __*Star Wars* (1977)__: In George Lucas's classic science-fiction film, rotoscoping was used to create the lightsabers. The actors held a prop stick covered in reflective tape; then, the animators added the glow in post-production using rotoscoping. 
2. __*The Birds* (1963)__: Alfred Hitchcock used rotoscoping to animate birds attacking people in his horror film *The Birds*.
3. __*The Lord of the Rings* (1978)__: Ralph Bakshi's animated *The Lord of the Rings* used the rotoscoping technique. Bakshi rotoscoped the battle scenes by using live actors to make the scenes look more dynamic. Peter Jackson's live-action *The Lord of the Rings* (2001) used motion capture, a process similar to the rotoscope technique, to create the character of Gollum, which was entirely made from computer-generated imagery (CGI). 
4. __*A Scanner Darkly* (2006)__: In Richard Linklater’s animated film, the animators traced over live-action footage of Keanu Reeves, Robert Downey Jr., Woody Harrelson, and Winona Ryder to animate versions of those actors. 
5. __*Guardians of the Galaxy* (2014)__: In this Marvel superhero film, rotoscoping was used to create the character of Rocket Raccoon. Footage of a real raccoon was captured; then, the animators traced the Rocket Raccoon character onto the live-action footage.
