trim After you’ve assembled your clips in rough chronological order in the timeline, you
begin to fine-tune the cut points (or edit points) between clips. Any time you make a clip in
a project longer or shorter, you’re trimming that clip. In Final Cut Pro, you can use a variety
of techniques to trim timeline clips and edit points, including ripple edits, roll edits, slip
edits, and slide edits.
Trim tool The editing tool that allows you to trim items in the timeline. You can select the
Trim tool by pressing the T key.
ultra-high-definition (UHD) Refers to video with a minimum resolution of 3840 x 2160
pixels. See also high-definition (HD).
uncompressed 8- and 10-bit 4:2:2 Video formats that can be used to store 8-bit or
10-bit 4:2:2 Y'CbCr video without employing data compression. Bypassing compression
reduces the computer’s processing load but increases the data rate considerably. A large-
capacity RAID storage system is typically required to work effectively with uncompressed
video. In many cases, Apple ProRes is a better choice. The data rate of uncompressed
4:2:2 video varies according to frame size and frame rate. As an example, at a frame size
of 1920 x 1080 and a frame rate of 29.97 fps, the data rate is 1.0 Gbps for uncompressed
8-bit 4:2:2 video and 1.3 Gbps for uncompressed 10-bit 4:2:2 video.
upstream Refers to clips that are to the left of the current clip in the timeline. When
you perform actions that ripple the project, upstream clips are not affected. See also
downstream, ripple edit.
value slider A type of numerical slider control that appears as a number, often to the
right of a basic slider. There are two ways to adjust a value slider: by dragging over the
number to decrease or increase the parameter value, or by double-clicking the number and
entering a new value.
variable speed Speed that varies dynamically, in forward or reverse motion, in a single
clip.
VCR Abbreviation for videocassette recorder. Generally refers to consumer equipment
used for recording video from various sources. Sometimes referred to as a VTR. See also
VTR.
vectorscope
A video scope in Final Cut Pro that shows the distribution of color in your
image on a circular scale. The vectorscope is useful for comparing the hue and intensity of
colors between two clips for the purposes of color correction. See also hue.
Video Animation editor You can show the Video Animation editor for clips in the timeline
to adjust effect parameters, create fade-ins or fade-outs, or change effects over time
using keyframes. See also Audio Animation editor, keyframe.
viewer When you play clips selected in the browser and the timeline, they appear in the
viewer.
VTR Abbreviation for videotape recorder. Generally refers to professional equipment used
for recording video from various sources.
watermark A visible graphic or text overlay applied to an image or video clip to indicate
that it’s protected by a copyright. Watermarks are used to discourage the use of images or
video clips without the copyright holder’s explicit permission.
WAVE (or WAV) An audio file format most commonly used for storing uncompressed linear
pulse code modulation (LPCM) audio data.
