In today's digital landscape, creating engaging video content is essential. Adding captions not only enhances accessibility but also boosts viewer engagement. FFMPEGAPI.net provides a powerful hosted solution for video and audio processing, allowing developers to easily transcribe videos and generate stylish TikTok captions with just a few API calls. This article will explore the AI Captions endpoint and demonstrate how it can be integrated into your applications.

Understanding the AI Captions Endpoint

The AI Captions endpoint at FFMPEGAPI.net is designed to extract audio from a video, transcribe it, and render styled captions directly onto the video. This service is particularly useful for creating content tailored for platforms like TikTok, where engaging visuals and clear captions are critical.

  • Transcribes audio with word timestamps.
  • Generates styled captions based on user preferences.
  • Returns caption artifact URLs for further use.

How to Use the AI Captions Endpoint

To utilize the AI Captions feature, you send a POST request to the /api/videos/add-tiktok-captions endpoint. The request must include a video URL and optionally various parameters to customize the captions such as subtitle style, language, and positioning.

  • Video URL is required.
  • You can customize the subtitle style to 'plain-white', 'yellow-bg', 'pink-bg', 'blue-bg', or 'red-bg'.
  • Specify the language with a language code or use 'auto'.
  • Adjust the aspect ratio to fit your video format: 16:9, 9:16, 4:3, or 3:4.
  • Control the caption wrapping limit and maximum lines displayed.
curl -X POST https://ffmpegapi.net/api/videos/add-tiktok-captions \
-H "Content-Type: application/json" \
-d '{"video_url": "https://example.com/video.mp4", "subtitle_style": "yellow-bg", "position": "bottom"}'
import requests

url = 'https://ffmpegapi.net/api/videos/add-tiktok-captions'
data = {
    'video_url': 'https://example.com/video.mp4',
    'subtitle_style': 'yellow-bg',
    'position': 'bottom'
}

response = requests.post(url, json=data)
print(response.json())
