monoscopic A 360° video file that uses a single projection. This is a flat (two-dimensional)
rendering that can be viewed on any screen. You can navigate monoscopic 360° video
in any direction, but there’s no real depth perception; viewing monoscopic video is like
looking around with only one eye open.
MP3 Refers to the MPEG-1 or MPEG-2 Audio Layer 3 compression standard and file
format. Like AAC, MP3 uses perceptual audio coding and psychoacoustic compression to
remove superfluous information that the human ear doesn’t hear.
MPEG (Moving Picture Experts Group) A group of compression standards for video and
audio, which includes MPEG-1, MPEG-2, and MPEG-4.
multicam clip A set of clips grouped together and synced by a common sync point. You
can use multicam clips to edit footage from multicamera shoots or other synced footage
in real time. While the active angle plays in the viewer, you can also view all angles playing
simultaneously in the angle viewer and easily cut and switch between them.
MXF An industry-standard file format for video and audio. Like QuickTime files, MXF
files contain information about the media inside. This information, also called metadata,
can include frame rate, frame size, creation date, and custom data created by a camera
operator, assistant, or archivist. See also frame rate, resolution.
nested sequence See compound clip.
NLE Short for nonlinear editor. See also nonlinear editing.
nondestructive editing
No matter how you edit clips in Final Cut Pro, the underlying media
is never touched. This is known as nondestructive editing, because none of the changes
and effects you apply to your footage affect the original source media files. Clips represent
your media, but they are not the media files themselves. The clips in a project simply point
to (link to) the source media files on your Mac or storage device. When you modify a clip,
you’re not modifying the media file, just the clip’s information in the project. Trimmed or
deleted pieces of clips are removed from your project only, not from the clips in your library
or from the source media files on your Mac or storage device.
non-drop frame timecode Timecode in which frames are numbered sequentially and no
timecode numbers are dropped from the count. In the case of NTSC video, the video frame
rate is actually 29.97 fps, and non-drop frame timecode is off by 3 seconds and 18 frames
per hour in comparison to actual elapsed time. See also drop frame timecode, NTSC
format.
non-interlaced video The standard representation of images on a computer. Also referred
to as progressive scan. The monitor displays the image by drawing lines, one after another,
from top to bottom.
nonlinear editing A video editing method that allows you to change the edits within a
program without having to re-create the entire program. When you use a nonlinear editing
application to edit a program, all footage used is stored on a computer or storage device
rather than on tape. This allows random access to all video, audio, and images as you edit.
See also linear editing.
NTSC format The video standard defined by the National Television Standards Committee,
the organization that originally defined North American broadcast standards. Analog NTSC
video has 525 interlaced lines per frame, a frame rate of 29.97 fps, and a limited color
gamut. Digital NTSC video has a frame size of 720 x 486 pixels (720 x 480 for DV and
DVD), and a frame rate of 29.97 fps. See also PAL format.
