PQ (Perceptual Quantizer) A high-dynamic-range (HDR) transfer function that relates
image signal values to absolute light levels produced by a display. PQ is standardized in
SMPTE ST 2084 and is one of the two supported transfer functions in the ITU-R Rec. 2100
standard for HDR video. PQ is used in formats such as HDR10, HDR10+, and Dolby Vision.
project A project provides a record of your editing decisions and the media you use. You
build your project by adding clips and editing them in the timeline. A project is also defined
by its video, audio, and rendering properties. In most cases, Final Cut Pro manages project
settings automatically based on the properties of the first clip you add to a project.
project properties A project’s video, audio, and rendering properties. In most cases,
Final Cut Pro manages a project’s properties automatically based on the properties of the
first clip you add to a project. If you must modify the project properties, choose video
and audio project properties based on how you intend to share your final movie with your
audience.
proxy files
You can use Final Cut Pro to transcode your original media to create proxy
files, which are smaller files with a lower data rate. Proxy files can be used for offline
editing or for editing when using a slower computer. Final Cut Pro creates video proxy
files using either the Apple ProRes 422 Proxy or H.264 format. You can create proxy
media in a variety of frame sizes from 12.5 percent to 100 percent of the original. See also
Apple ProRes 422 Proxy, H.264, media representation.
QuickTime Cross-platform multimedia technology from Apple. Widely used for production,
post-production, and distribution of video, audio, and interactive programs.
range
Instead of selecting whole clips, you can select a range within any clip in
the timeline or the browser. You can trim range selections, mark them with ratings and
keywords, and modify them in other ways. You can adjust the range start and end points by
dragging either side of the selection. In the timeline, you can also select a range that spans
multiple clips. In the browser, you can set multiple ranges within one or more clips, and you
can select and deselect ranges after you set them.
Range Selection tool The editing tool that allows you to select a range in the timeline. You
can select the Range Selection tool by pressing the R key.
Rec. 2020 Short for Rec. ITU-R Recommendation BT.2020, a color space standard with a
very large gamut (range of color).
Rec. 709 Short for ITU-R Recommendation BT.709, the standard broadcast format for
high-definition (HD) television.
rectilinear A standard video file, as opposed to a spherical 360° video file that has
equirectangular projection (showing all parts of a three-dimensional sphere flattened in a
video frame, similar to world maps that depict the globe as a two-dimensional rectangle).
red laser media Traditional DVD burners and players use a red laser when working with
DVD media. Blu-ray burners and players use a blue laser when working with Blu-ray media.
The blue laser has a shorter wavelength, making it possible to store more data on a disc.

render To process video and audio with any applied effects or transitions, and store the
result on your Mac or storage device as a render file. These render files are stored with
your Final Cut Pro event and project files. When you publish or export a project, it’s also
rendered to create the output files.
