Downloading ffmpeg (General instructions)
Today, I'll show you the steps to download ffmpeg in your Windows machine. This is needed for tools like rav1e_gui, which uses ffmpeg to pre-process and post-process video files when encoding them to the new AV1 video format.
Below are the steps:
Navigate to https://ffmpeg.zeranoe.com/builds/
Select the nightly build which is the first one shown in "Version". Select the 64-bit Windows version if you have a 64-bit machine, and select "Static" in the Linking column. Then, click on "Download Build".
When the download finishes, press "Open"
Go to the ffmpeg folder
Go to the "bin" folder
Extract the "ffmpeg.exe" executable to your preferred location
