What is FFmpeg?

FFmpeg is a powerful, cross-platform tool for handling multimedia files. It consists of a suite of programs and libraries designed to handle video, audio, and other multimedia files. The software is free and open-source, and runs on all major operating systems including Windows, Mac, and Linux.

Whether you need to convert, transcode, or stream multimedia files, FFmpeg has you covered. It's well-suited for professionals who work with multimedia files on a daily basis, as well as for hobbyists who want to encode videos for personal use.

Why Convert from WMV to MP4?

WMV is a common video format used by Microsoft on its Windows operating system. While it's a popular format, not all devices and media players support it – which can be problematic if you want to view your WMV videos on other devices.

As a result, many people choose to convert WMV files to the MP4 format, which is a widely-supported video format that can be played on most devices and media players. Additionally, MP4 files tend to be smaller in size than WMV files, which can be an advantage if you want to save storage space on your device or upload the video to the internet.

How to Convert WMV to MP4 with FFmpeg

Converting a WMV file to MP4 using FFmpeg is a straightforward process that involves using the command line interface. Follow the steps below to convert your WMV file to MP4:

Step 1: Download and Install FFmpeg

Before we can begin converting WMV to MP4, we'll need to make sure we have FFmpeg installed on our system. You can download FFmpeg from the official website.

Step 2: Open a Terminal

Next, open a terminal or command prompt window on your computer. On Windows systems, you can do this by pressing the Windows key + R, type in "cmd", and hit enter. On MacOS, open Terminal from the Launchpad or Spotlight.

Step 3: Navigate to the WMV File Location

Navigate to the location of the WMV file you want to convert using the command line. For example, if your WMV file is located in the "Downloads" folder, type:

cd Downloads/

Step 4: Convert the WMV File to MP4

Finally, we can begin the conversion process by typing the following command into Terminal or Command Prompt:

ffmpeg -i input.wmv output.mp4

In this command, replace "input.wmv" with the name of your WMV file, and "output.mp4" with the desired name for your MP4 file. For example, if your WMV file is named "video.wmv" and you want to convert it to "video.mp4", the command would look like this:

ffmpeg -i video.wmv video.mp4

FFmpeg will start converting your WMV file to the MP4 format – the process should only take a few minutes depending on the size of your original file.
