What are common file formats for transcripts and associated media in digital court reporting?

• A. HTML for final transcripts; AAC for audio; CSV for machine-readable transcripts
• B. PDFs for final transcripts; WAV/MP3 for audio; XML/ASCII for machine-readable transcripts
• C. DOCX for final transcripts; MP4 for video; JSON for metadata
• D. RTF for final transcripts; FLAC for audio; YAML for machine-readable transcripts

Answer: (B)

Transcripts and their media are organized to ensure reliability, accessibility, and machine readability. PDFs are used for final transcripts because they lock in the exact formatting, pagination, and appearance of the document, making them dependable and easily archivable across systems. For the accompanying audio, WAV or MP3 are the common choices: WAV provides high-quality, lossless audio that preserves the verbatim record, while MP3 offers smaller file sizes with broad playback support. For machine-readable data, XML or ASCII are favored because XML provides a structured format that can carry metadata and be parsed by software, and ASCII (plain text) ensures broad compatibility when raw text needs to be ingested without special formatting.

Other formats tend to fall short in this context: HTML doesn’t preserve fixed formatting like a court record requires; editable formats such as DOCX or RTF can introduce disputes over authenticity; video formats (like MP4) aren’t needed for transcripts themselves; and while alternatives like AAC or FLAC exist, they’re not as universally adopted for official archival and interoperability as WAV/MP3 for audio and XML/ASCII for machine-readable data.
