Apple ProRes RAW The Apple ProRes RAW and Apple ProRes RAW HQ codecs preserve
all of the camera sensor’s pristine raw data to deliver extraordinarily high-quality images.
ProRes RAW brings to raw video the same great performance, quality, and ease of use that
ProRes has brought to conventional video, in a format ideal for HDR content creation. Being
able to use the raw image sensor data directly in Final Cut Pro during post-production
gives you more control over the processing of the image, including demosaicing, linear-to-
log conversions, and custom LUTs.
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. See also keyframe, Video Animation editor.
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.
audio sample rate The number of times an audio signal is measured, or sampled, per
second. A higher sample rate produces higher-quality audio and larger file sizes, and a
lower sample rate produces lower-quality audio and smaller file sizes.
Audio Units The standard real-time audio effect format for audio applications used
with macOS.
audio waveforms Visual representations of the actual sound. An audio waveform’s
amplitude and length change according to the underlying sound’s volume and duration. A
short, loud sound such as a drum beat has a sharp, peaked waveform, whereas low-level
crowd noise has a lower, more uniform waveform. These properties make it easier to find
specific edit points when trimming clips or keyframing effects.
audition
In Final Cut Pro, you can organize related clips into sets, called auditions, from
which you can choose one clip to use. You can create an audition composed of different
clips to try out multiple takes, or you can create an audition composed of multiple versions
of the same clip to preview different effects. Auditions appear in the browser and timeline
as clips with an audition icon in the top-left corner.
automatic audio sync The “Use audio for synchronization” option in the multicam clip
creation process makes precision sync adjustments using audio waveforms in the angles of
a multicam clip. This is the same audio sync technology that you can use to automatically
analyze and sync clips together into a compound clip. See also compound clip, multicam
clip.
AVCHD A high-definition (HD) video format that uses Advanced Video Coding (AVC)
compression (also known as MPEG-4 part 10 or H.264). Many Blu-ray players can play red
laser discs with AVCHD format content, making this a common way to distribute short HD
video projects using a standard red laser disc.
Background Tasks window
A window in Final Cut Pro that shows the progress of
importing, transcoding, analysis, rendering, sharing, and other tasks performed in the
background.
