Glossary 478
Apple ProRes 4444 XQ The highest-quality version of Apple ProRes for 4:4:4:4 image sources
(including alpha channels), with a very high data rate to preserve the detail in high-dynamic-
range imagery generated by today’s highest-quality digital image sensors. Apple ProRes 4444 XQ
preserves dynamic ranges several times greater than the dynamic range of Rec. 709 imagery—
even against the rigors of extreme visual effects processing, in which tone-scale blacks or
highlights are stretched significantly. Like standard Apple ProRes 4444, this codec supports up to
12 bits per image channel and up to 16 bits for the alpha channel. Apple ProRes 4444 XQ features
a target data rate of approximately 500 Mbps for 4:4:4 sources at 1920 x 1080 and 29.97 fps.
Apple ProRes 4444 An extremely high-quality version of Apple ProRes for 4:4:4:4 image
sources (including alpha channels). This codec features full-resolution, mastering-quality 4:4:4:4
RGBA color and visual fidelity that is perceptually indistinguishable from the original material.
Apple ProRes 4444 is a high-quality solution for storing and exchanging motion graphics and
composites, with excellent multigeneration performance and a mathematically lossless alpha
channel up to 16 bits. This codec features a remarkably low data rate compared to uncompressed
4:4:4 HD, with a target data rate of approximately 330 Mbps for 4:4:4 sources at 1920 x 1080 and
29.97 fps. It also offers direct encoding of, and decoding to, both RGB and Y’C

pixel formats.
Apple ProRes 422 HQ A higher-data-rate version of Apple ProRes 422 that preserves visual
quality at the same high level as Apple ProRes 4444, but for 4:2:2 image sources. With
widespread adoption across the video post-production industry, Apple ProRes 422 HQ offers
visually lossless preservation of the highest-quality professional HD video that a single-link
HD-SDI signal can carry. This codec supports full-width, 4:2:2 video sources at 10-bit pixel depths,
while remaining visually lossless through many generations of decoding and reencoding. The
target data rate of Apple ProRes 422 HQ is approximately 220 Mbps at 1920 x 1080 and 29.97 fps.
Apple ProRes 422 A high-quality compressed codec offering nearly all the benefits of Apple
ProRes 422 HQ, but at 66 percent of the data rate for even better multistream, real-time editing
performance. The target data rate of Apple ProRes 422 is approximately 147 Mbps at 1920 x 1080
and 29.97 fps.
Apple ProRes 422 LT A more highly compressed codec than Apple ProRes 422, with roughly 70
percent of the data rate and 30 percent smaller file sizes. This codec is perfect for environments
where storage capacity and data rate are at a premium. The target data rate of Apple ProRes 422
LT is approximately 102 Mbps at 1920 x 1080 and 29.97 fps.
Apple ProRes 422 Proxy An even more highly compressed codec than Apple ProRes 422
LT, intended for use in offline workflows that require low data rates but full-resolution video.
The target data rate of Apple ProRes 422 Proxy is approximately 45 Mbps at 1920 x 1080 and
29.97 fps.
aspect ratio A film or video frame’s width-to-height ratio on any viewing screen. Standard-
definition (SD) video (used for regular television screens) has an aspect ratio of 4:3. High-
definition (HD) video has an aspect ratio of 16:9.
Audio Animation Editor You can show the Audio Animation Editor for clips in the Timeline
to adjust effect parameters, create fade-ins or fade-outs, or change effects over time
using keyframes.
audio components Audio files can contain a single audio channel or multiple audio channels.
Final Cut Pro automatically groups audio channels into audio components according to how the
channels are configured for the clip. In Final Cut Pro, you can expand the audio portion of clips to
view and edit audio components down to the individual channel level.
