S/N Ratio
The Signal-to-Noise Ratio, measured in decibels, is the ratio between the
maximum signal level and the noise level with no signal present. The higher
the value, the better the sound reproduction.
Source
In Profile operations, a source is any signal (video, audio, or timecode)
presented to the machine inputs. A VTR output, a satellite downlink, a
camera output, and a facility router output are all examples of sources.
Status bar
The status bar at the bottom of most windows provides status information,
short explanations of commands and errors.
Tape
See Cartridge Tape.
Text insertion point
The I-shaped pointer which appears in a text input area. Clicking the mouse
in a text input area causes the text cursor to appear in that area. Whatever
information you type on the keyboard appears in the text input area
displaying the text cursor.
Tool Tips
A tool tip is a small pop-up window that displays a single line of text
describing the purpose of a control in a window. A tool tip is hidden most of
the time, appearing only when the user puts the cursor on a tool and leaves it
there for approximately one-half second. The tool tip appears near the cursor
and disappears when the user clicks a mouse button or moves the pointer off
of the tool.
Tracks
Clips and masters are made up of individual tracks. A clip may consist of any
combination of a video track, timecode track, and up to 16 audio tracks. A
master may consist of any combination of a timecode track, 0-4 video tracks,
and 0-16 audio tracks.
