description: "Full text transcription of video audio content.\n\n**DEFINITION**:\n\nA VideoTranscript is the complete textual representation of all spoken\ncontent in a video. It extends VideoTextContent with transcript-specific\nproperties and inherits all provenance tracking capabilities.\n\n**RELATIONSHIP TO VideoSubtitle**:\n\nVideoSubtitle is a subclass of VideoTranscript because:\n1. A subtitle file contains everything a transcript needs PLUS time codes\n2. You can derive a plain transcript from subtitles by stripping times\n3. This inheritance allows polymorphic handling of text content\n\n```\nVideoTranscript VideoSubtitle (is_a VideoTranscript)\n\u251C\u2500\u2500 full_text \u251C\u2500\u2500 full_text (inherited)\n\u251C\u2500\u2500 segments[] \u251C\u2500\u2500 segments[] (required, with times)\n\u2514\u2500\u2500 (optional times) \u2514\u2500\u2500 subtitle_format (SRT, VTT, etc.)\n```\n\n**SCHEMA.ORG ALIGNMENT**:\n\nMaps to `schema:transcript` property:\n\
> \"If this MediaObject is an AudioObject or VideoObject, \n> the transcript of that object.\"\n\n**CIDOC-CRM E33_Linguistic_Object**:\n\nE33 is the class comprising:\n> \"identifiable expressions in natural language or code\"\n\nA transcript is a linguistic object derived from the audio track of\na video (which is itself an E73_Information_Object).\n\n**TRANSCRIPT FORMATS**:\n\n| Format | Description | Use Case |\n|--------|-------------|----------|\n| PLAIN_TEXT | Continuous text, no structure | Simple search indexing |\n| PARAGRAPHED | Text broken into paragraphs | Human reading |\n| STRUCTURED | Segments with speaker labels | Research, analysis |\n| TIMESTAMPED | Segments with time markers | Navigation, subtitling |\n\n**GENERATION METHODS** (inherited from VideoTextContent):\n\n| Method | Typical Use | Quality |\n|--------|-------------|---------|\n| ASR_AUTOMATIC | Whisper, Google STT | 0.80-0.95 |\n| MANUAL_TRANSCRIPTION | Human transcriber | 0.98-1.0 |\n| PLATFORM_PROVIDED\
\ | YouTube auto-captions | 0.75-0.90 |\n| HYBRID | ASR + human correction | 0.95-1.0 |\n\n**HERITAGE INSTITUTION CONTEXT**:\n\nTranscripts are critical for heritage video collections:\n\n1. **Discovery**: Full-text search over video content\n2. **Accessibility**: Deaf/HoH access to spoken content\n3. **Preservation**: Text outlasts video format obsolescence\n4. **Research**: Corpus analysis, keyword extraction\n5. **Translation**: Base for multilingual access\n6. **SEO**: Search engine indexing of video content\n\n**STRUCTURED SEGMENTS**:\n\nWhen `segments` is populated, the transcript has structural breakdown:\n\n```yaml\nsegments:\n - segment_index: 0\n start_seconds: 0.0\n end_seconds: 5.5\n segment_text: \"Welcome to the Rijksmuseum.\"\n speaker_label: \"Narrator\"\n confidence: 0.94\n - segment_index: 1\n start_seconds: 5.5\n end_seconds: 12.3\n segment_text: \"Today we'll explore the Night Watch gallery.\"\n speaker_label: \"Narrator\"\n confidence:\
\ 0.91\n```\n\n**PROVENANCE** (inherited from VideoTextContent):\n\nAll transcripts include:\n- `source_video`: Which video was transcribed\n- `generated_by`: Tool/person that created transcript\n- `generation_method`: ASR_AUTOMATIC, MANUAL_TRANSCRIPTION, etc.\n- `generation_timestamp`: When transcript was created\n- `overall_confidence`: Aggregate quality score\n- `is_verified`: Whether human-reviewed\n"
