How to Install FFmpeg on Windows

Understandably, most people are a little lost when it comes to using command-line programs like FFmpeg. But don’t worry, I was there not too long ago, and now I’ll try explain as thoroughly as I can how to install it and start using it.
But first, a little info from their site:
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge.
So really, you’re doing yourself a huge favour by installing it, you just need a little help to get started.

1: Download

2: Unzip

3: Add to Path

Finally, we need to add the bin folder, which contains the ffmpeg.exe file, to our system path to allow us to run the commands easily.
Technically, you could always do something like C:\ffmpeg\bin\ffmpeg.exe -codecs,
but it’s much easier to type ffmpeg -codecs.
If you try that right now, you’ll get an error saying that the ffmpeg is not recognized as an internal or external command.

That basically means windows has not idea what you’re talking about.
All we need to do is add C:\ffmpeg\bin to our system path, and it’ll understand us.
So, in the Start Menu, right click on Computer and choose Properties.

Then select Advanced system settings:

Open up the Environment Variables:

And then edit the Path variable:

The Path is just a list of folders that contain commands you’re allowed to use without typing in the full path of the exe files.
So, go ahead and add C:\ffmpeg\bin to the end of the line, making sure that there’s a semi-colon (;) after the previous folder:

4: Use it!

That’s it!
