In today's digital landscape, engaging video content is more important than ever. Adding captions to your videos not only improves accessibility but also enhances viewer engagement. With FFMPEGAPI.net's AI Captions feature, you can effortlessly transcribe videos and render TikTok-style captions—all without dealing with server setup or FFmpeg infrastructure management.

What is the AI Captions Endpoint?

The AI Captions endpoint at FFMPEGAPI.net allows developers to transcribe a video and create stylish TikTok-style captions. This feature extracts audio from the video, transcribes it with word timestamps, and integrates rendered captions directly into the video.

This API is ideal for developers looking to automate video processing tasks, enhance SaaS applications, or streamline content pipelines.

  • Transcribes audio with word timestamps.
  • Renders styled captions in various formats.

Here’s a breakdown of the parameters you can use:

  • video_url (required): The URL of the video you want to process.
  • subtitle_style (optional): Choose from styles like plain-white, yellow-bg, pink-bg, blue-bg, or red-bg.
  • language (optional): Specify the language code or use 'auto' for automatic detection.
  • aspect_ratio (optional): Define the aspect ratio (e.g., 16:9, 9:16).
  • max_chars_per_line (optional): Control caption wrapping from 5 to 80 characters.
  • max_lines (optional): Set the maximum number of caption lines from 1 to 4.
  • position (optional): Position the captions on the screen (top, center, or bottom).
