description: "Abstract base class for all textual/derived content from videos.\n\n**DEFINITION**:\n\nVideoTextContent is the abstract parent for all text that is extracted,\ntranscribed, or derived from video content. This includes:\n\n| Subclass | Source | Description |\n|----------|--------|-------------|\n| VideoTranscript | Audio | Full text transcription of spoken content |\n| VideoSubtitle | Audio | Time-coded caption entries (SRT/VTT) |\n| VideoAnnotation | Visual | CV/multimodal-derived descriptions |\n\n**PROVENANCE REQUIREMENTS**:\n\nAll video-derived text MUST include comprehensive provenance:\n\n1. **Source**: Which video was processed (`source_video`)\n2. **Method**: How was content generated (`generation_method`)\n3. **Agent**: Who/what generated it (`generated_by`)\n4. **Time**: When was it generated (`generation_timestamp`)\n5. **Version**: Tool/model version (`model_version`)\n6. **Quality**: Overall confidence (`overall_confidence`)\n\n**PROV-O ALIGNMENT**:\n\nMaps\
