| RCA cable | cable that usually has a yellow, a red, and a white plug that is used to connect a camcorder to a VCR, DVD, or capture card on a computer |
| Aspect ratio | ratio of width to height in the dimensions of a frame; i.e., frame aspect ratio of NTSC video is 4:3, some motion-picture frame sizes use a more elongated aspect ratio of 16:9 |
| Timeline | part of video editing window that displays tracks |
| Title | adding words to video |
| Transition | special effects, such as fade in and fade out, that can be set to occur between frames in an animation |
| Video capture | the process of transferring video to the computer |
| Video editing | making changes to taped footage |
| Voice overlay | a voice track over music or video |
| Video Home System (VHS) tape | a strip of magnetic media – usually consisting of a plastic/Mylar base, a layer of metallic particles, and a bonding agent – onto which video and audio signals can be recorded |

| Animation | a simulation of movement or the perception of motion created by the rapid display of a series of still images |
| Frame | a single still image in a video or animation |
| Looping | repeating a function until a certain condition is met |
| Morphing | animation technique in which one image is transformed into another image |
| Transition | special effects, such as "fade in" and "fade out," that can be set to occur between frames in an animation |
| Warping | a special effect that results in distortion of an image |
| Vector animation | moves an object along a predetermined path on the screen; the path could be a straight line or it could include any number of curves; often the object does not change, although it might be resized or reshaped; also known as path animation |
| Frame animation | a type of animation that is based on the changes that occur from one frame to another; sometimes known as cell animation |
| Rendering | the final step in creating a 3-D animation that involves giving objects attributes such as colors, surface textures, and degrees of transparency |
