  • Subtitle URL: Burn in subtitles from an ASS/SSA file.
  • Watermark URL: Add a watermark image to the merged video.
  • Async processing: Start the merge job and get a job ID immediately.
curl -X POST https://ffmpegapi.net/api/merge_videos \n-H 'Content-Type: application/json' \n-d '{"video_urls": ["https://example.com/intro.mp4", "https://example.com/main.mp4"], "dimensions": "1920x1080"}'
