A method for creating transparency, such as a bluescreen key or a chroma key.
Start and end points for animated effects. Adobe Premiere Elements automatically generates the frames between keyframes to create
smooth movement. See also interpolation and tweening.
Replacing part of one TV image with video from another image. Also called blue screen. See also chroma key.
An edit in which the video ends before the audio, which acts as a subtle transition from one scene to the next. To perform an L-cut in the
Timeline window, hold down the Alt key and drag the right edge of the video to the left; the result looks like the letter L.
A technique used to preserve the original aspect ratio of a motion picture when played on a TV. Letterboxing adds black bars to the top
and bottom of the screen.
A compression scheme that doesn’t affect signal quality, such as the transfer of DV via an IEEE 1394 connection.
A compression scheme that degrades quality. Lossy algorithms compress digital data by eliminating the data least sensitive to the human
eye, and offer the highest compression rates available.
The effect of the combined values for brightness and contrast.
A method for creating movies that combines traditional filmmaking, animation, and virtual 3D gaming technology. Machinima is the
combined form of “machine/cinema” or “machine/animation.”
DVD markers indicate chapters, scenes, and stop points for a DVD menu. In Premiere Elements, DVD markers are also called scene
markers. Clip markers signify important points within a clip. Timeline markers indicate scenes, locations for titles, or other significant points within
an entire movie. Clip markers and timeline markers are used for positioning and trimming clips.
See matte.
The transparent area of an image, typically defined by a graphic shape or a bluescreen background. Also called a mask.
Musical Instrument Digital Interface. A standard used to share data between electronic music equipment and computers.
A timeline that appears at the bottom of the Monitor panel when the Sceneline is displayed. (See also timeline.)
Motion JPEG. A compression standard used to convert each video frame into a compressed JPEG image. MJPEG is best suited for
broadcast-quality video, and is preferable over MPEG for footage that contains a great deal of movement. See also MPEG.
A DVD menu that has a moving background image instead of a still image, animated buttons, or both.
MPEG-1 Audio Layer 3. Both a compression standard and a file format for digital audio.
Motion Pictures Expert Group. Also, a type of compression and a video format. Unlike JPEG, where individual frames are compressed,
MPEG compression calculates and encodes only the differences between one frame and its preceding frame.
Compression standard used to convert analog video for use in digital applications. It was designed to deliver near-broadcast-quality
video through a standard speed CD-ROM. The compression ratio is about 100:1.
Extension of the MPEG-1 standard. It was designed to meet the requirements of TV broadcast studios. MPEG-2 is the broadcast-quality
video found on DVDs and requires a decoder for playback.
Developed for HDTV but became obsolete when MPEG-2 was discovered to adequately meet HDTV requirements. Often confused with
