A sample in a sequence of temporally compressed samples that does not rely on other samples in the sequence for any of its information. Key frames are placed into temporally compressed sequences at a frequency that is determined by the key frame rate.
a frame of the underlay which has a mask associated with it that determines objects to be tracked. The key frame is a property of the tracking segment, and is not subject to change.
If the video portion of a movie has been compressed using both intraframe compression and interframe compression, a decoder cannot decompress the majority of the video frames without referring to preceding--and sometimes succeeding--frames. However, the first frame in the movie, and usually other frames as well, do not have interframe dependencies and can be decoded in isolation. These frames are called key frames. Key frames, besides the one that starts the movie, enable the decoder to decompress other frames without playing the movie from the beginning.
a complete frame containing all of the information
a complete frame that contains all the information needed to view the frame, and it sets a new starting point for frame differencing
a completely recorded frame, with all of its information intact
a frame in which you define a change in an animation or include frame actions to modify a movie
a frame or cell in animation which is used asa guide for the other frames, or inbetweens
a frame rendered without compression
a frame that has an actual picture of a character in the animation, it either shows where the object starts and ends in a scene, or it show the important scenes where certain actions or features are captured
a point in encoded video where the data for the entire frame is transmitted, rather than just the changes
a reference frarne in your video sequence that the CODEC uses to assess where redundant and changing information appears
a single still image (frame) in an animated sequence that occurs at an important point in that sequence
A fully self-contained, independent frame of video that can exist without reference to any other frames.
A frame that a codec uses to save images that don't change, such as a background.
A video frame containing all the data needed to construct an image without reference to previous frames. See Also: delta frame
Consisting of front and center-rails of hard maple, the key frame with its front and center-pins, provides for the proper location and spacing of the piano keys.
A video frame in which all of the video information is recorded in compressed fashion. If the clip has a large amount of motion, better playback will occur with every frame being a Key Frame. If there is very little motion, such as a narrator, a higher number of Delta Frames will give satisfactory playback. In general, making every 3rd frame a Key Frame is a good choice with the current Indeo technology algorithm. Also see Delta Frame.
Part of a compressed video that contains the complete information of picture. The frames that occur between two key frames only contain information that represents the change that occurs from one frame to the next, thus greatly decreasing the amount of information needed and reducing the file size.
A frame of video that contains the data for the entire frame rather than just the differences from the previous frame.
In movie compression, the key frame is the baseline frame against which other frames are compared for differences. The key frames are saved in their entirety, while the frames in between are compressed based on their differences from the key frame. In Media Convert, for example, if you set the Key Frame option to 10, every 10th frame will be a key frame. This translates to a higher level of compression and playback speed than a movie that was compressed with the Key Frame option set at a lower number. However, if you want to stop a movie in different places, in order to view different frames, a lower Key Frame option will provide better stop and start viewing.
Markers within an effects sequence that are used to adjust the profile of any transition.
Is a special purpose marker that denotes the change in value to an applied affect parameter.
A video frame with all the data for a single image. They are always the first frame of a video file and can be inserted at any point to avoid image degradation.
In animation, key frames (also keyframes) are the drawings which are essential to define a movement. They are called "frames" because their position in time is measured in frames on a strip of film. A sequence of keyframes defines which movement the spectator will see, whereas the position of the keyframes on the film (or video) defines the timing of the movement.
