Overview
IEC TR 62712:2011 is a Technical Report from the IEC that summarizes a market and product survey of professional tape-less camera recorders and provides guidelines on the possibilities for standardization. It focuses on file-based camera recorders and addresses five core components: codec, file format, metadata, recording media, and interface. The report documents current product practice (eight product families surveyed) and recommends paths for interoperability and future standard work.
Key Topics
- Codec
- Video codecs observed: MPEG‑2, MPEG‑4 AVC / H.264, JPEG2000, DV. These are industry-supported codecs referenced to ISO/IEC or SMPTE where applicable.
- Audio: majority use uncompressed linear PCM; one product used AC‑3 (ATSC A/52B).
- File format
- Widespread use of MXF (SMPTE ST 377/378/379 etc.) with OP‑1a and OP‑Atom operational patterns for single-file and clip-per-file workflows.
- Other containers noted: MP4 (ISO/IEC 14496-12/14), AVI Type 2, QuickTime, and MPEG‑2 TS for stream-based containers.
- Metadata
- Differentiates technical metadata (essence playback and decoding parameters) and descriptive metadata (content, shooting context). MXF-based products commonly include metadata specification examples.
- Recording media
- Surveyed both proprietary and non‑proprietary removable media types used by camera recorders.
- Interface
- Investigation limited to file transfer and compressed bit-stream transfer interfaces to support file-based workflows.
- Standardization guidance
- Discusses two approaches: product-based standardization and essence-technology-based standardization. Notes MXF revision activity in SMPTE and the desirability of IEC alignment.
Applications and Who Uses It
IEC TR 62712 is practical for:
- Camera and recorder manufacturers planning interoperable tape-less devices
- Broadcasters and production houses evaluating ingest and editing workflows (MXF vs MP4 vs TS)
- Post-production and asset management teams implementing metadata and file-transfer workflows
- Systems integrators and procurement managers specifying compatibility across devices
- Standards developers and test labs assessing standardization priorities for codecs, containers, and metadata schemas
