# Merge Video and Audio with FFmpeg

This simple FFmpeg command merges a video file `video.mp4` and an audio file `audio.mp4` without re-encoding. It copies both streams as they are, ensuring fast processing and no quality loss.  

```sh
ffmpeg -i video.mp4 -i audio.mp4 -c:v copy -c:a copy output.mp4
```
