1. Download the latest FFmpeg build from a reputable source (e.g., gyan.dev or BtbN).
2. Extract the downloaded archive to a directory of your choice (e.g., `C:\ffmpeg`).
3. Add the FFmpeg `bin` directory (e.g., `C:\ffmpeg\bin`) to your system’s `PATH` environment variable. This allows you to run FFmpeg from any command prompt window.
* **macOS:**
1. The easiest way to install FFmpeg on macOS is using Homebrew. If you don’t have Homebrew installed, install it by running the following command in your terminal:
`/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”`
2. Once Homebrew is installed, run the following command to install FFmpeg:
`brew install ffmpeg`
* **Linux (Debian/Ubuntu):**
1. Open a terminal window.
2. Run the following command to install FFmpeg:
`sudo apt update`
`sudo apt install ffmpeg`

**Step 2: Open a Command Prompt or Terminal**

* **Windows:** Open the Command Prompt by searching for “cmd” in the Start menu.
* **macOS:** Open the Terminal application (located in `/Applications/Utilities`).
* **Linux:** Open a terminal window.

**Step 3: Use the FFmpeg Command to Convert MOV to MP4**

The basic FFmpeg command to convert MOV to MP4 is:

bash
ffmpeg -i input.mov output.mp4

Replace `input.mov` with the actual name of your MOV file and `output.mp4` with the desired name for the converted MP4 file. For example:

bash
ffmpeg -i myvideo.mov myvideo.mp4

This command will use the default settings for the conversion. To customize the conversion, you can add various options to the command.

**Common FFmpeg Options:**

* **`-c:v libx264`:** Specifies the video codec to use (H.264). This is generally the best choice for compatibility.
* **`-c:a aac`:** Specifies the audio codec to use (AAC).
* **`-b:v 2000k`:** Sets the video bitrate to 2000kbps. Adjust this value to control the video quality. Higher values result in higher quality and larger files.
* **`-b:a 128k`:** Sets the audio bitrate to 128kbps.
* **`-vf scale=1280:720`:** Scales the video to a resolution of 1280×720. Change the values to your desired resolution.
* **`-crf 23`:** Use Constant Rate Factor encoding. This is a quality-based encoding mode. A CRF of 23 is a good starting point. Lower values result in higher quality and larger files.
* **`-preset slow`:** Sets the encoding speed. Slower presets result in better quality but take longer to encode. Possible values are: `ultrafast`, `superfast`, `veryfast`, `faster`, `fast`, `medium` (default), `slow`, `slower`, `veryslow`.

**Example Command with Options:**

bash
ffmpeg -i input.mov -c:v libx264 -c:a aac -b:v 2000k -b:a 128k -vf scale=1280:720 -crf 23 output.mp4

This command will convert `input.mov` to `output.mp4` using the H.264 video codec and AAC audio codec, set the video bitrate to 2000kbps and the audio bitrate to 128kbps, scale the video to a resolution of 1280×720, and use CRF encoding with a value of 23.

**Step 4: Run the Command**

Press Enter to execute the command. FFmpeg will begin the conversion process, and you’ll see progress information in the command prompt or terminal.
