To get all captions of a YouTube video, follow these steps, depending on your needs and whether you want a manual or automated approach. Note that captions must be available for the video (either auto-generated or uploaded by the creator).

Manual Method (Using YouTube’s Built-in Transcript Feature)

Open the Video: Go to YouTube in a web browser and navigate to the desired video.
Check for Captions: Click the video to pause it. Look for a “CC” (Closed Captions) icon near the bottom-right corner of the player. If visible, captions are available.
Access the Transcript:
- Scroll down to the video description and click “Show more.”
- Find and click “Show transcript” (if available). This opens a transcript panel on the right side of the video with timestamps and text.
Toggle Timestamps: Click the three vertical dots at the top-right of the transcript panel and select “Toggle timestamps” to show or hide timestamps, depending on your preference.
Copy the Transcript:
- Scroll to the bottom of the transcript, click and hold after the last word, then drag to the top to highlight all text.
- Press Ctrl + C (Windows) or Command + C (Mac) to copy.
Paste and Save: Open a text editor (e.g., Notepad, TextEdit, or Word), paste the text with Ctrl + V or Command + V, and save as a .txt file or your preferred format.

Note: This method only works on the YouTube website, not the mobile app.

For Content Creators (Downloading Captions from Your Own Video)

If you own the video, you can download captions directly from YouTube Studio:

Log in to YouTube Studio: Go to studio.youtube.com.
Select Video: Click “Content” in the left menu, then choose the video.
Access Subtitles: Click “Subtitles” in the left menu, then select the language.
Download Captions: Click the three-dot menu next to the subtitle track and select “Download.” Choose a format like .srt, .vtt, or .sbv.
Edit or Use: Open the downloaded file in a text editor or subtitle editor (e.g., Aegisub) for further use.

Note: You can only download caption files for videos on channels you manage.

Automated Method (Using Third-Party Tools)

If you need captions in a specific format (e.g., .srt) or for videos you don’t own, use a reputable third-party tool:

Choose a Tool: Popular options include:
- DownSub: A free online tool for downloading subtitles.
- Notta: Offers transcription and subtitle downloads with high accuracy.
- 4K Download: A desktop app for subtitle extraction.
Copy Video URL: Open the YouTube video, click “Share” below the video, and copy the URL.
Use the Tool:
- Paste the URL into the tool’s input field.
- Select the desired language and format (e.g., .srt, .txt).
- Click “Download” or “Extract” and save the file.
Verify: Open the file to ensure accuracy, as auto-generated captions may contain errors.

Caution: Use trusted tools to avoid security risks. Some tools may have ads or require payment for advanced features.

Using the YouTube API (For Developers)

For bulk caption extraction or app integration, use the YouTube Data API:

Set Up API Access: Create a project in the Google Cloud Console, enable the YouTube Data API v3, and obtain an API key.
List Caption Tracks: Use the captions.list endpoint to retrieve available caption tracks for a video. Example:
```
GET https://www.googleapis.com/youtube/v3/captions?part=snippet&videoId=VIDEO_ID&key=API_KEY
```
Download Captions: Use the captions.download endpoint to fetch a specific caption track. Example:
```
GET https://www.googleapis.com/youtube/v3/captions/CAPTION_ID?tfmt=srt&key=API_KEY
```
Limitations:
- You can only download captions for your own videos unless the video owner has made them publicly accessible.
- API usage has quota limits (approximately 200 units per caption download).
Alternative: Some developers scrape the timed text URL (e.g., https://www.youtube.com/api/timedtext?...) from the video page source, but this is unreliable, may violate YouTube’s terms, and risks IP blocking.

Additional Tips

Language Selection: If captions are available in multiple languages, select your preferred language from the “Subtitles/CC” settings or the transcript’s dropdown menu.
Auto-Generated Captions: These may have errors due to accents, background noise, or complex audio. Review and edit if accuracy is critical.
Accessibility: Captions enhance accessibility for deaf or hard-of-hearing viewers and improve SEO by making content searchable.
No Captions Available?: If the video lacks captions, consider using transcription services like Rev or Notta to generate a transcript from the audio.

Limitations

Not all videos have captions, especially if the creator disabled them or YouTube’s auto-captioning isn’t supported for the language or audio quality.
The YouTube mobile app doesn’t support transcript viewing, but you can enable captions via the “CC” button.
Some third-party tools or API methods may not work for auto-generated captions or restricted videos.
