Page 253: Frame number
fps Abbreviation for frames per second.
frame A single still image. Film and video are made up of a series of these images.
Although a film frame is a photographic image, a video frame contains one or more fields.
frame number The last part of the key number. The frame number consists of the footage
number and the frame counter and indicates how many feet and frames into the film a
particular frame occurs. See also

HD video See
high definition video Refers to any of a wide range of video formats, including the 24p
format, providing a higher-quality image than standard definition video. Enhancements
can include increased resolution, a wider aspect ratio, and progressive scanning. See also

identifier In Cinema Tools, a combination of one or more letters, numbers, or both, that
identify a shot, scene, take, video reel, sound roll, lab roll, or camera roll.
ink number A feet and frame count number added to the edge of workprints and
magnetic film soundtracks. Also known as an Acmade number.
interlaced See
interlaced video A video frame format that divides the lines in a frame of video into two
fields, each consisting of alternating odd and even lines, which are scanned at different
times. Used in standard definition video. See also

interpositive (IP) A low-contrast positive film print made from an original camera
negative. It is not projectable as a full-color image, because it has an orange mask on it
like a negative. IPs are typically used as an intermediate step in creating opticals and
duplicate negatives.
key number Latent feet and frame count numbers found on the film edge. Key numbers
are often superimposed by the telecine onto the edge of the video frames (this is called
window burn). Cinema Tools uses key numbers to help match digital edits back to the
original camera negative. Key numbers consist of a key prefix, which is unchanging
throughout an entire roll of film, and a frame number, which consists of a footage number
and a frame count number. Telecine systems also often add a frame type identifier to the
key number. For example, in the key number KJ 291010 5867+07, the key prefix is “KJ
291010” and the frame number is “5867+07.” Also known as edge code.
latent key number A number added to the film edge during its manufacturing process.
Also known as latent edge code. See also
