In animation and filmmaking, a key frame (or keyframe) is a drawing or shot that defines the starting and ending points of a smooth transition.These are called frames because their position in time is measured in frames on a strip of film or on a digital video editing timeline.
Sophisticated animation software enables the animator to specify objects in an image and to define how they should move and change during the tweening process. The software may be used to manually render or adjust transitional frames by hand or may be used to automatically render transitional frames using interpolation of graphic parameters.
Frames 2–4 are smear frames, those being elongated inbetweens. In animation, a smear frame is a frame used to simulate motion blur. Smear frames are used in between key frames. [1] This animation technique has been used since the 1940s. [1] Smear frames are used to stylistically visualize fast movement along a path of motion. [2] [3] [4]
Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognized as an artistic medium, specifically within the entertainment industry.
Traditional animation (or classical animation, cel animation, or hand-drawn animation) is an animation technique in which each frame is drawn by hand. The technique was the dominant form of animation of the 20th century, until there was a shift to computer animation in the industry, such as digital ink and paint and 3D computer animation .
Onion skin of frame 7 of this image showing previous 3 frames. In 2D computer graphics, onion skinning is a technique used in creating animated cartoons and editing films to view several frames at once. This way, the animator or editor can make decisions on how to create or change an image based on the previous image in the sequence.
Computer animation is the art of creating moving images via the use of computers. It is a subfield of computer graphics and animation . Increasingly it is created by means of 3D computer graphics , though 2D computer graphics are still widely used for stylistic, low bandwidth, and faster real-time rendering needs.
Normally, 24 frames are needed for one second of film. In ordinary filming, the frames are photographed automatically, one after the other, in a movie camera. In special effects or animation filming, the frames are often shot one at a time. The size of a film frame varies, depending on the still film format or the motion picture film format.
