offline editing A post-production process in which raw footage is copied and edited
without affecting the original camera media (film, tape, or file-based media). After a
program has been completed in the offline edit (typically using proxy media at a lower
resolution), an online edit is performed to re-create the edit using the original media.
opacity The level of a clip’s transparency.
optimized files
You can use Final Cut Pro to transcode your original media to create
optimized files in the Apple ProRes 422 format, which provides better performance during
editing, faster render times, and better color quality for compositing. See also Apple
ProRes 422, media representation.
outgoing clip The clip a transition segues from. For example, if clip A dissolves to clip B,
clip A is the outgoing clip. See also incoming clip.
Out point See edit point.
overwrite edit In an overwrite edit, one or more source clips overwrite any clips in the
primary storyline or a selected storyline, starting at a range selection start point or at
the skimmer or playhead position. No clip items are rippled forward, so the duration of
your project remains the same. Overwriting is purely duration-based and works on range
selections only, irrespective of clip boundaries. See also range, storylines.
PAL format Acronym for Phase Alternating Line, a 25 fps (625 lines per frame) interlaced
video format used by many European countries. Digital PAL video has a frame size of
720 x 576. See also NTSC format.
parallax The difference between the horizontal positions of the two cameras, or eyes, in
stereoscopic 360° media. See also stereoscopic.
Photos and Audio sidebar
A pane in the Final Cut Pro sidebar that provides access to all
of your photo and audio collections. When you select an item in the sidebar (such as an
album in Photos or a category of sound effects), the item’s contents are displayed in the
browser. Depending on which apps and which version of macOS you’re using, you may see
photo libraries from Photos or other photos apps, or music and sound libraries from Music,
GarageBand, or Logic Pro.
pitch Sounds are perceived as high or low depending on their frequency, or the number of
times per second a sound wave cycles from positive to negative and back to positive. The
word that musicians most commonly use for frequency is pitch. The higher the frequency,
the higher the pitch. Modifying the speed of a clip affects the pitch of the audio. Slow
motion creates low pitch, and fast motion creates high pitch.
pixel One dot in a video or still image. The more pixels in an image, the higher the
resolution. See also resolution.
playhead A gray vertical line that marks the current position in a project in the timeline or
a clip in the browser. You can move the playhead by dragging it or clicking another area of
the timeline or browser. You use the playhead to scrub, or move through your project and
play it back from different locations. The playhead is fixed in place unless you move it or
click elsewhere. See also skimmer.
Position tool The editing tool that allows you to place items in the timeline. You can select
the Position tool by pressing the P key.
post-production The phase of film or video editing in which all of the production elements
are organized, assembled, and output.
