900Final Cut Pro User Guide
source media files The original files (video, audio, and still images or graphics) that you
import into Final Cut Pro. A clip you use in Final Cut Pro points to the location where the
source media file is stored (either on your Mac, a storage device, or a camcorder, camera,
or device). Changes made to clips within Final Cut Pro do not affect the source media files.
special effects Visual effects applied to clips and projects, such as motion, compositing,
keying, and retiming effects.
spill suppression A color correction operation that neutralizes any green or blue fringing
or light bounce that’s tinting the subject being keyed. Spill suppression works by applying
the complementary (opposite) color of the color that’s being made transparent.
split edit
Final Cut Pro allows you to set separate video and audio start and end points
in an individual clip. These edits, known as split edits, are a common technique in most
dialogue scenes in films and television shows. You can use split edits to introduce the
sound of a new shot or scene before cutting to the video of that shot or scene. Conversely,
you can use a split edit to extend the audio of a shot over a subsequent shot.
SRT (SubRip Text) A subtitle format supported by Facebook, YouTube, and Vimeo. The
SRT format is simple: Each caption has a number, a start and end timecode (in decimal
timecode), and one or more lines of text. SRT captions can be imported or exported as
separate files. Unlike captions in other formats, exported SRT captions can be read and
edited in a plain text editor. SRT caption files have the filename extension .srt.
standard-definition (SD) Refers to the original NTSC and PAL video frame sizes. NTSC
uses 480 or 486 active lines per frame, and PAL uses 576 active lines. See also high-
definition (HD).
standard dynamic range (SDR) The conventional technique for processing luminance
(brightness) and color values in images, developed in the mid-1900s, with a nominal
maximum brightness of 100 nits (candelas per square meter) and a dynamic range of
6 to 10 stops. Some newer imaging devices can display high-dynamic-range (HDR) images,
representing a much wider range of brightness levels.
stereo Short for stereophonic, which describes audio that contains two different channels.
Audio level changes are automatically made to both channels at the same time.
stereoscopic A 360° video file that is split into two views designated for the left and right
eyes. This type of video is designed to be viewed through a special headset or glasses that
can project each of the two views into the appropriate eye. Stereoscopic video simulates
the depth perception (in three dimensions) that people experience in the real world when
they have two eyes open.
storylines All instances of the timeline contain a primary storyline, which is the main
sequence of clips you build to create your movie. Storylines are sequences of clips
connected to the primary storyline. You can use storylines for the same purposes as
connected clips (such as creating cutaways, compositing titles and other graphics, and
adding sound effects and music). See also compositing, cutaway shot.
straight cut A cut in which both the video and audio clip items are cut at the same time.
subframe A subframe has 1/80 the duration of a video frame and is thus a more precise
unit of reference when editing audio at the sample level.
