June 2026 FFMPEG API Team

In today's content-driven world, merging videos programmatically can significantly enhance your workflow, especially for developers creating SaaS applications or automation tools. FFMPEGAPI.net offers a powerful hosted REST API to streamline video processing tasks with minimal setup. In this article, we'll explore how to use the API to compress and merge videos effectively.

What is FFMPEGAPI.net?

FFMPEGAPI.net is a hosted REST API designed specifically for FFmpeg-powered video and audio processing. It eliminates the need for server setup or managing FFmpeg infrastructure, allowing developers to focus on creating and deploying their applications.

  • No server setup required.
  • API-key authentication for secure access.
  • Ideal for developers, SaaS apps, content pipelines, and AI agents.

Using the Compress Video Endpoint

One of the key functionalities provided by FFMPEGAPI.net is the ability to compress videos. This can be achieved using the '/api/compress_video' endpoint, which allows you to compress a video to a smaller H.264/AAC MP4 format.

  • Supports compression using quality-first CRF settings.
  • Allows setting of maximum dimensions to prevent upscaling.
  • Can handle large videos with asynchronous processing.
import requests

url = 'https://ffmpegapi.net/api/compress_video'

payload = {
    'video_url': 'https://example.com/video.mp4',
    'crf': 28,
    'preset': 'medium',
    'max_width': 1280,
    'audio_bitrate': '128k',
    'async': true
}

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

Parameters for Video Compression

The '/api/compress_video' endpoint accepts various parameters to customize the compression process.

Here are the key parameters you can utilize:

  • video_url (string): The URL of the video to compress (required).
  • crf (integer): Quality value from 18 to 35 (default is 28).
  • preset (string): H.264 encoding preset options.
  • max_width (integer): Optional maximum output width.
  • max_height (integer): Optional maximum output height.
  • audio_bitrate (string): AAC audio bitrate options (default is 128k).
  • target_size_mb (number): Optional target output size in MiB.
  • async (boolean): Enables background processing for large videos.

To sum up, FFMPEGAPI.net provides the best way to merge videos programmatically with its easy-to-use hosted REST API. With no server management required and a robust set of features, it simplifies video processing tasks for developers. Whether you need to compress videos or facilitate automated content workflows, FFMPEGAPI.net is your go-to solution.
