Format: Sometimes this refers to a file type (.avi, .mov, etc.), but more commonly it refers
to the specific frame size (image size), frame shape, pixel shape, and sometimes frames per
second.
Frame: This means one whole image. Video is made up of a series of frames that play fast
enough to appear to be a continuous image. The number of frames playing per second is
called the frame rate and is often measured in frames per second (fps).
Import: When you bring a media file into a Premiere Pro project, nothing is really moved
into the project file. Instead, shortcuts are created that contain information about the media,
and it’s those shortcuts that you combine when editing.
Media: This is your original content. This could be video files, graphics, photos, animation,
music, voice-over, or audio special effects (like a sword clash or explosion).
Metadata: Metadata is information about information. There are many forms of metadata,
but they always include information about something. For example, metadata associated
with a video file might include the camera system used to record it or the name of the
camera operator.
Pixel: This is a single dot, or point of light. Pixels have color settings (sometimes called
values) that are often (but not always) measured as a combination of red, green, and blue
color.
Project: This is the container for all of your clips and sequences. A project is stored as a
file that stores all your creative work.
Sequence: This is a series of clips, combined in a particular order, often in multiple layers.
Most of the creative work you will perform in Premiere Pro will be on sequences and on the
clips in sequences.
Timecode: This is a system for defining a particular moment in time in a piece of recorded
media in terms of hours, minutes, seconds, and frames. Professional video recording
systems always record timecode for every frame, and this is the primary system used to
record time when working in a nonlinear editing system.
Transition: In a sequence, when one clip ends and another begins, the transition between
the two is most commonly a cut. However, there are many transition effects available to
add visual interest or enhance storytelling. A dip to black, for example, usually tells the
viewer some time has passed.
