Definition

Technical specifications relating to a moving image resource.

For information on punctuation, see the Punctuation section below.

Guidelines

Prefer use of a separate field for each unique term. For instance, a wide screen video:

300			1 videodisc (104 min.) : ǂb sound, color ; ǂc 4 3/4 in.
345			ǂc 2.00:1
345			ǂd wide screen ǂ2 rdaar

For guidance on describing and encoding the attributes of video recording carriers see OLAC Online Audiovisual Catalogers' Best Practices for Cataloging DVD-Video and Blu-Ray Discs.

1st Indicator

Undefined. The 1st indicator position is undefined and contains a blank.

	Undefined

2nd Indicator

Undefined. The 2nd indicator position is undefined and contains a blank.

Subfields

ǂa Presentation format

The format used in the production of a projected image (e.g., Cinerama, IMAX). For a list of RDA-controlled terms, see RDA Presentation Format.

RDA 3.17, Projection Characteristic of Motion Picture Film, is explicitly limited to technical specifications relating to the projection of actual motion picture film. Presentation format is treated in RDA 3.17.2 and recorded here in subfield ǂa. This subfield is not to be used for any video format.

Do not confuse presentation format with aspect ratio, which is treated in RDA 7.19. Numerical aspect ratios are recorded in field 345 subfield ǂc. Verbal aspect ratio designators are recorded in field 345 subfield ǂd.

300			1 film reel (approximately 17 min.) : ǂb sound, color ; ǂc 16 mm
345			3D ǂ2 rdapf

300			1 film reel (25 min.) : ǂb sound, color ; ǂc 65 mm
345			IMAX ǂ2 rdapf

300			13 film reels (approximately 129 min.) : ǂb sound, color ; ǂc 35 mm
345			Panavision ǂ2 rdapf

300			1 film reel (69 min.) : ǂb sound, black and white ; ǂc 35 mm
345			standard sound aperture ǂ2 rdapf

300			9 film reels (86 min.) : ǂb sound, color ; ǂc 35 mm
345			Techniscope ǂ2 rdapf

300			1 film reel (11 min.) : ǂb silent, black and white ; ǂc 35 mm
345			standard silent aperture ǂ2 rdapf

300			11 film reels (94 min.) : ǂb sound, color ; ǂc 35 mm
345			Cinemascope ǂ2 rdapf

ǂb Projection speed

The speed at which a projection device must be operated to produce the moving image intended.

RDA 3.17, Projection Characteristic of Motion Picture Film, is explicitly limited to technical specifications relating to the projection of actual motion picture film. Projection speed is treated in RDA 3.17.3 and recorded here in subfield ǂb. This subfield is not to be used for any video format.

300			1 film reel (5 min., 3 sec.) : ǂb silent, black and white ; ǂc 35 mm
345			ǂb 24 fps

300			1 film reel (1 min., 28 sec.) : ǂb silent, black and white ; ǂc 35 mm
345			ǂb 16 fps

300			2 film reels (84 min.) : ǂb silent, black and white ; ǂc 16 mm
345			ǂb 20 fps

ǂc Aspect ratio value

A numerical ratio of the width to the height of a moving image. This subfield may be used for all moving image media including film, video, and online resources.

300			6 videodiscs : ǂb digital, sound, color ; ǂc 4 3/4 cm
345			ǂc 16:9
345			ǂd wide screen ǂ2 rdaar

ǂd Aspect ratio designator

A general description of the ratio of the width to the height of a moving image. This subfield may be used for all moving image media including film, video, and online resources. For a list of RDA-controlled terms, see RDA Aspect Ratio Designation.

300			1 videodisc (approximately 85 min.) : ǂb sound, color ; ǂc 4 3/4 in.
345			ǂd letterboxed

300			3 videodiscs (approximately 8 hr., 35 min.) : ǂb sound, color ; ǂc 4 3/4 in.
