Video Transcription: Complete Guide (2026)

Video transcription converts spoken content from YouTube, Loom, Vimeo, TikTok, and other platforms into searchable text, captions, and subtitles — making video content accessible, repurposable, and indexable by search engines. This guide covers every major video platform, output format options, accessibility requirements, and workflows for turning video into written content.

Quick Navigation

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:

  1. Upload your video file (MP4, MOV, WebM, or other supported formats)
  2. AI processes the audio track with speaker identification
  3. 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. These guides cover the complete workflow for each platform.

YouTube

Business Video Platforms

Social Media & Streaming

Meetings as Video

Zoom, Teams, and Google Meet recordings are video files that benefit from the same transcription approach:

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.

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.

Content Repurposing from Video

A single video transcript can be transformed into 10+ marketing assets — including SEO-optimized blog posts, social media snippets, and email newsletters — by using LLM prompts to extract key insights and structured summaries from BrassTranscripts output. These guides cover the workflows.

Choosing a Video Transcription Service

Choosing a video transcription service depends on the trade-off between convenience and capability — built-in platform tools like YouTube auto-captions handle basic use cases, while dedicated AI services like BrassTranscripts provide speaker identification, multi-format export (TXT, SRT, VTT, JSON), and pay-per-file pricing with no subscription.

Approach Best For Cost Formats
YouTube auto-captions YouTube-only content Included On-screen only
Loom/Vimeo built-in Platform-specific captions Plan-dependent Limited export
BrassTranscripts Any video file, all platforms $2.50-$6.00/file TXT, SRT, VTT, JSON
Descript Video editing + transcription $24-33/mo SRT, VTT
Rev.com Human-reviewed accuracy $1.50+/min SRT, VTT, TXT

BrassTranscripts approach: Upload any video file, get speaker-identified transcripts in all 4 formats. No subscription, no platform lock-in. Works with recordings from YouTube, Loom, Zoom, or any video source.

Frequently Asked Questions

How do I transcribe a video to text?

Most services accept MP4, MOV, WebM, and other common video formats directly — no need to extract audio first. BrassTranscripts provides output in TXT (readable text), SRT (subtitles), VTT (web captions), and JSON (structured data).

BrassTranscripts accepts 11 audio and video formats including MP4, MOV, WebM, MPEG, MP3, WAV, M4A, FLAC, OGG, OPUS, and WMA. Files up to 250MB and 2 hours in length are supported. Most video platforms (YouTube, Loom, Vimeo) export in MP4, which works directly without conversion.

How do I add captions to YouTube videos?

Yes. Under ADA Title III, WCAG 2.1 AA, and Section 508, video content with audio must include synchronized captions or transcripts.
