1、 1 Scope This practice describes the data format of a list generated by electronic film editing systems to be used as the master reference for a film negative cutter when conforming the original negative to the electronic work tape. The scope of this format does not consider the needs of the pre-ass
2、embler whose job is to pull the appropriate negative prior to the actual cutting and splicing of specific edits. A separate format for such a task will be developed. The negative cutters task is one of precision coupled with speed, and the reference cutting list must strive to provide only the essen
3、tial information with a minimum of clutter for that specific task, and in a form immediately recognizable. As a result, white space and accurate and familiar representation of data may be as important as the data itself. The columnar layout and negative edge identifier/coding scheme replication is t
4、herefore considered crucial. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this practice.

9、ly. 3.1.2 duration: The number of frames used in an overlapping transition effect. 3.1.3 film feet: That unique part of the key number which increments by one regularly along a continuous section of film, typically each foot. This is also referred to as the footage indicator. 3.1.4 film frame offset
10、: The offset, not included as part of the key number, which is the frame count away from a film feet indicator. This offset may be an increment (+) or decrement (-) to an associated film feet indicator. 3.1.5 film prefix code: That common part of the key number which is used to identify the stock an
11、d batch of film. The code, as used in this practice, is an exact replication of the code marked on the film edge, including all alpha and numeric characters. 3.1.6 head: The first frame of original negative to be included in the finished product. 3.1.7 roll: The unique identifier for the original ca
12、mera negative roll containing the footage to be spliced. 3.1.8 runtime: The cumulative running time, beginning with the first cut in the list. This information is displayed in two forms: film feet and film frame offset, and the corresponding SMPTE time code as it appears on the work tape. 3.1.9 shot
13、: A sequence of negative frames, cut to cut. 3.1.10 shot duration: The number of negative frames in a shot, measured in feet plus remaining frames. 3.1.11 tail: The last frame of the original negative to be included in the finished product. 3.1.12 white space: Blank, unprinted space on a line with b
14、eginning and ending columns specified. 3.2 Terms defined by SMPTE 254, ANSI/SMPTE 270, and SMPTE 271 3.2.1 frame line: The junction between two exposed film images on the film. 3.2.2 key number: A number (sometimes imprecisely referred to as an edge number or footage number) that is printed with ink
15、 or exposed onto film at the time of manufacture. The numbers are placed at regular intervals, typically submultiples of one foot. A key number is composed of a film prefix code and a film feet count. 3.2.3 latent image key number: A key number which is exposed onto the film at the time of manufactu
16、re. 3.2.4 reference mark: A mark, usually a dot, which is included in the latent image of the key number, and which is aligned to a perforation on the film. 3.3 Term defined by SMPTE RP 195 3.3.1 perf offset: The count of the number of perforations from the frameline to the reference mark (the count
17、 includes the perforation adjacent to the reference mark). The procedure for determining the perf offset on any given exposed film format is specified in SMPTE RP 195. RP 194-2004 Page 3 of 6 pages 3.4 Term defined by SMPTE RP 197 3.4.1 film feet edge number: The string of characters which defines a
18、 single film frame, including the key number, film frame offset, and perf offset, and is both human and machine readable. The syntactic definition of a film feet edge number is given in SMPTE RP 197. The following types of edge numbers are defined: BAR Machine readable latent-image bar code per SMPT
19、E 254, ANSI/SMPTE 270, or SMPTE 271. LHR Human readable version of machine readable latent-image barcode. LAT Latent image characters not conforming to the above standards. INK Other printed characters applied to the film after processing. 4 Layout 4.1 Header information Information placed at the he

21、indication of whether the frames are counted ahead from the previous start of foot (+) or back from the next start of foot (-). The count direction may be different for the head and tail columns (see 4.2 for a description of the data). 4.1.3 Page information Columns 60-80, first line of header infor

RP 194-2004 Page 4 of 6 pages 4.2.2 Roll Columns 7-14, eight alphanumerics (upper case alphas) identifyin
24、g the source camera negative roll. 4.2.3 Transition Columns 17-21, alphabetic characters, identifying the type of transition. The text may be C, indicating a cut, or MATCH, indicating that the head of this shot matches the tail of the preceding shot - if, for instance, an optical is to be intercut w
25、ith a camera roll. 4.2.4 Prefix Columns 24-32, nine alphanumerics. The film prefix code, exactly as it appears on the film. In the uncommon case where the film prefix codes of the head cut and tail cut differ, the film prefix code of the head cut should be used. In this case, the film prefix code of
26、 the tail cut may be noted in a user comment. 4.2.5 Head Columns 36-42, four numerics indicating film feet, one increment/decrement symbol (+ or -), plus two numerics indicating film frame offset (with leading zeros). The head cut of the shot to be spliced. The + or - indicates whether the frames ar
27、e counted ahead from the previous start of foot (+) or back from the next start of foot (-). Either notation may be used; however, the same notation should be used throughout the list. 4.2.6 Head perf offset Columns 44-46, the letter P followed by one or two digits indicating the pert offset at the
28、start of the foot. This field is required for film and key number formats where the key number repetition rate is not divisible by the frame repetition rate (for example, 35-mm 3 perforations). For formats not requiring the perf specifier, this field must be blank (refer to SMPTE RP 195 for an expla
29、nation of the perf offset). 4.2.7 Tail Columns 49-55, four numerics (film feet), one increment/decrement symbol (+ or -), plus two numerics (film frame offset) with leading zeros.

This field is required for film and key number formats where the key number repetition rate is not divisible by the frame repetition rate (for example, 35-mm 3 perforations). For format
32、s not requiring the perf specifier, this field must be blank (refer to SMPTE RP 195 for an explanation of the perf offset). 4.2.9 Shot duration Columns 60-67 (right justified from column 67), up to five numerics indicating footage (no leading zeros) plus an increment symbol (+) plus two numerics ind

Standard SMPTE format (using SMPTE standard drop frame/nondrop frame notation
35、 for NTSC, as defined in SMPTE 258M).

Preferred s
37、ize is 10 characters per inch; the column assignments given in 4.2 should be used. This example of the negative cutters conform list is formatted in typewriter font (Courier, 12 CPI). In this example, perf offsets are used; and both head and tail frames are counted forward from the preceding start o
38、f foot (+). The column ruler is provided for information only. It is not part of the required format (see example 1). 5.2 Proportionally-spaced font When printed in a proportionally-spaced font, the following formatting rules should be observed: a serif font is preferred for legibility; character si
39、ze should be no smaller than 10 points, 12 points is preferred; the same font should be used throughout. Enlarged characters may be used for emphasis of the head, tail, and runtime columns, as shown in example 2; tab stops corresponding to the column assignments in 4.2 should be used in order to pre
40、serve ample white space. This example of the negative cutters conform list is formatted in 12-point Times, with emphasized columns in 14 point. In this example, perf offsets are used, and both head and tail frames are counted forward from the preceding start of foot (+). RP 194-2004 Page 6 of 6 page
