The term "key frame" is commonly used in digital animation and refers to a specific frame in a sequence that sets the starting point for a movement or change. The spelling of "key frame" is straightforward and is pronounced as [kiː freɪm], with the "k" and "f" sounds being pronounced as they appear. The diphthong "ey" is pronounced as [i:], while the "r" sound is pronounced as a soft tap or flap rather than a full "r" sound. Overall, the phonetic transcription of "key frame" accurately reflects its spelling and pronunciation.
A key frame is a fundamental concept used in animation and video editing. It refers to a specific frame in a sequence of frames that serves as a reference point or anchor for the animation or video effects. Key frames allow animators and editors to define specific points in time where the movement or characteristics of an object or element are defined.
Key frames play a pivotal role in various animation techniques like digital, traditional, and computer-generated animations. They help in creating smooth and realistic motion by defining the beginning and end points of a movement or transition. By establishing the key frames, artists can then fill in the intermediate frames to achieve the desired motion.
In video editing, key frames are used in a similar way but focus more on the alteration of properties of an effect or an object over time. For instance, in a video editing software, key frames can be set to mark the beginning and ending of a color change effect, allowing the software to automatically interpolate and adjust the properties of the effect over the determined time frame.
Overall, key frames are essential tools in animation and video editing as they provide a foundation for creating fluid and dynamic movement or effects. They enable artists and editors to define and control the changes and characteristics of objects or effects throughout a sequence, resulting in visually appealing and engaging animations and videos.
The word "keyframe" originated from the field of animation and refers to a significant frame that holds important information. The etymology of "keyframe" can be traced back to the early days of traditional hand-drawn animation, known as cel animation.
In cel animation, a sequence of drawings is created to give the illusion of movement. Each drawing in the sequence is called a frame, and animators would often start by creating important or defining frames for the movement they wanted to achieve. These key frames acted as reference points or milestones in the animation process.
The term "keyframe" likely evolved from the concept of a "key drawing" or "key pose", which were pivotal frames that dictated the overall motion. Animators would draw these key poses, and the other frames in between, known as "in-between frames", were filled in by assistant animators to complete the smooth motion.
