Overview
ISO 1223:2003 - "Cinematography - Picture areas for motion-picture films for television - Position and dimensions" defines the maximum safe picture areas on 16 mm and 35 mm motion‑picture film for transmission or transfer to television. The standard covers film material shot for projection and film specially prepared for television, and applies to formats intended for either or both 4:3 and 16:9 aspect ratios. It harmonizes existing recommendations from ITU‑R, EBU and SMPTE and provides practical guidance for scanning, telecine transfer and film‑to‑TV workflows.
Key topics
- Scope and purpose: Specifies position and dimensions of scanned areas on 16 mm and 35 mm film for TV use, ensuring consistent framing and safe image areas for broadcast.
- Scanning requirements: Differentiates procedures for images shot for optical projection versus those shot for television; identifies non‑standard areas that must be documented if used.
- Scanned area tables: Provides defined scanned area dimensions for:
- Projection film scanned for 4:3 and 16:9 television
- Film specially shot for 4:3 and 16:9 television (including Super‑16 and Super‑35 variants)
- Presentation methods: Recommends how to handle differing aspect ratios on TV - full‑screen (crop to fill) and letter‑box (add black bars) presentations.
- Annex A: Explains the anchor dimensions and principles used to calculate scanned areas and illustrates cropping vs. letter‑boxing.
- Documentation requirement: Non‑standard image areas must be specified in transmission/transfer documentation.
Applications
ISO 1223:2003 is practical for professionals involved in film-to-broadcast workflows:
- Broadcasters and transmission engineers preparing film content for 4:3 or 16:9 TV
- Telecine and scanning operators who set scanned area, framing and centering parameters
- Post‑production and color grading facilities ensuring safe title and composition areas
- Film laboratories, archivists and restoration teams standardizing transfer outputs
- Camera, projector and telecine equipment manufacturers referencing anchor dimensions for design and calibration
Using ISO 1223 ensures consistent framing, avoids unintended cropping of critical picture elements, and facilitates interoperability across production, transfer and broadcast chains.
