About this file

The document is an Excel spreadsheet (Attachment E) detailing file naming conventions for AV (audiovisual) final deliverables for a National Park Service project. The comprehensive naming protocol specifies a 30-character maximum filename structure with specific fields including park alpha code, AV number, audio configuration, accessibility features, language options, and file extension.

The naming convention breaks down complex file specifications across multiple dimensions, including resolution types (UHD, 4K, HD, SD, 8K), audio configurations (5.1 surround, stereo, mono), accessibility features (audio description, open captions), language options (English, German, Spanish, etc.), and supported file extensions (.mov, .mp4, .scc, .srt, .wav). The document provides detailed guidelines for creating standardized audiovisual file names, likely for interpretive films related to Pecos National Historical Park, with precise rules for representing technical and linguistic characteristics of the media files.
