5 Ways to Transcribe YouTube Videos: From Subtitle Extraction to SRT Export

There are many reasons you might want to transcribe a YouTube video: taking notes on content, summarizing videos for blog posts, creating subtitle files, and more.

This article introduces 5 methods for transcribing YouTube videos, comparing them by ease of use, accuracy, and functionality.

Method 1: Use YouTube's Auto-Generated Subtitles

The easiest approach is to use YouTube's built-in auto-caption feature.

Steps

1. Open the target video on YouTube
2. Click the "Subtitles/CC" button at the bottom right of the video player
3. Subtitles will appear on screen

Copying as Text

1. Expand the video description below the video
2. Click "Show transcript" (it may appear in the description or under the "..." menu)
3. A timestamped transcript appears
4. Select and copy the text

Pros & Cons

• Pros: No additional tools needed, free
• Cons: Accuracy can be poor (especially for non-English languages), cannot download as SRT/VTT files, unavailable for videos without auto-captions

Method 2: Use Chrome Extensions

Several Chrome extensions specialize in downloading YouTube subtitles.

Popular Extensions

• YouTube Summary with ChatGPT & Glasp: A Chrome extension by Glasp that extracts YouTube subtitle text with ChatGPT-powered AI summarization

Pros & Cons

• Pros: Operate directly from the browser, mostly free
• Cons: Depend on YouTube's subtitle data (won't work without captions), accuracy matches YouTube's auto-captions

Method 3: Download Subtitles with yt-dlp

yt-dlp is an open-source command-line tool that can download subtitle files directly from YouTube.

Steps

# List available subtitles
yt-dlp --list-subs "https://www.youtube.com/watch?v=VIDEO_ID"

# Download auto-generated subtitles in SRT format
yt-dlp --write-auto-subs --sub-langs en --convert-subs srt --skip-download "https://www.youtube.com/watch?v=VIDEO_ID"

Pros & Cons

• Pros: Direct SRT/VTT file download, supports batch processing
• Cons: Requires command-line knowledge, depends on YouTube's subtitle data

Method 4: Download Video and Transcribe with Whisper

Instead of relying on YouTube's auto-captions, transcribe the actual audio using AI (Whisper). This works even for videos without subtitles and delivers higher accuracy.

Command-Line Approach

# Download audio with yt-dlp
yt-dlp -x --audio-format mp3 "https://www.youtube.com/watch?v=VIDEO_ID"

# Transcribe with Whisper
whisper downloaded_audio.mp3 --model medium --language en --output_format srt

Using a GUI Tool

GUI tools eliminate the need for command-line operations. WhisperApp includes built-in yt-dlp integration, so you can simply enter a URL and it handles downloading and transcription in one step.

Pros & Cons

• Pros: Works on videos without subtitles, high accuracy, directly generates SRT/VTT files
• Cons: Downloading and processing take time, command-line setup required for manual approach

Method 5: Real-Time Transcription During Playback

Transcribe a video in real time as it plays on your PC, without downloading it.

How It Works

This method captures your PC's internal audio (via stereo mix or WASAPI loopback) and feeds it to a Whisper model in real time. Using WhisperApp's real-time transcription feature, you can simply play a YouTube video and get text output automatically.

Pros & Cons

• Pros: No download needed, works with any video streaming service
• Cons: Takes as long as the video's runtime, affected by playback environment noise

Comparison Summary

Conclusion

Choose your YouTube transcription method based on your goals and technical comfort level:

• Ease of use: YouTube auto-captions or Chrome extensions
• Accuracy: Whisper-based transcription
• Subtitle files needed: yt-dlp + Whisper, or WhisperApp

For videos without existing subtitles or when accuracy matters most, Whisper-based transcription is the most reliable approach. GUI tools make it accessible even without technical knowledge.
