How Video Transcription Works
AI video transcription extracts the audio track from a video file, processes it through speech recognition, and returns text with timestamps and optional speaker labels — typically completing a 60-minute video in 1-3 minutes.
The process:
- Upload your video file (MP4, MOV, WebM, or other supported formats)
- AI processes the audio track with speaker identification
- Download transcripts in your preferred format:
- TXT — Clean readable text with speaker labels
- SRT — Subtitle format for YouTube, Premiere, Final Cut
- VTT — Web caption format for HTML5 players (W3C standard)
- JSON — Structured data with word-level timestamps
For a detailed format comparison, see our transcript format decision guide or the comprehensive SRT, VTT, JSON format guide.
Platform-Specific Guides
Video platforms like YouTube, Loom, and Vimeo offer native auto-captioning, but professional workflows require exporting SRT or VTT files from a dedicated transcription service like BrassTranscripts to ensure cross-platform compatibility, speaker identification, and SEO indexing.

Video Formats and Captions
SRT is the universal caption standard for video editors like Premiere Pro and DaVinci Resolve, while VTT is the web standard required for HTML5 players and WCAG accessibility compliance. The VTT specification is maintained by the W3C. BrassTranscripts provides all four formats — SRT, VTT, TXT, and JSON — with every transcription.
| Format | Use Case | Video Player Support |
|---|---|---|
| SRT | YouTube, Premiere, Final Cut, DaVinci Resolve | Universal |
| VTT | HTML5 web players, WCAG compliance | Modern browsers |
| TXT | Reading, show notes, blog posts | N/A (text only) |
| JSON | Custom apps, data analysis, search indexing | Developer use |
SRT vs VTT: SRT is more universally supported by video editing software and platforms. VTT is the W3C web standard with better styling options (speaker color coding, positioning). YouTube accepts both.

Accessibility and Compliance
Video transcription is legally required for accessibility under multiple regulations — not optional for public-facing content.
- ADA Compliance Transcription Guide — Requirements under ADA Title III, Section 508, and WCAG 2.1 AA
The W3C's WCAG 2.1 Success Criterion 1.2.2 specifically requires that "captions are provided for all prerecorded audio content in synchronized media" at the Level A (minimum) conformance level — meaning any organization claiming WCAG compliance must caption its video content.
Key requirements:
- All video with audio must include synchronized captions or transcripts
- Applies to websites, educational content, government media, and businesses
- VTT format with proper timing satisfies most web accessibility standards
- Non-compliance risks legal action under ADA and state accessibility laws
BrassTranscripts provides VTT output with speaker labels and precise timestamps, meeting WCAG 2.1 AA caption requirements.
