Part 1. A full guide to using FFmpeg to convert MP4 to WebM
The free and open-source software project, FFmpeg, converts MP4 to WebM using command lines. It consists of many programs and libraries that handle audio, video, and multimedia files and streams. They include an audio/video codec library used by several other projects, libavcodec, an audio/video container mux, a demux library, libavformat, and FFmpeg command line program. The FFmpeg program is designed for command-line-based processing of audio and video files and format transcoding and video scaling.
FFmpeg is developed mostly on Linux but is compliable under most operating systems such as Windows, Mac OS X, and others like iOS, Android, MorphOS, and AmigaOS.
Use the following guide to convert MP4 to WebM using FFmpeg:
Step 1: Get FFmpeg
For FFmpeg to convert MP4 to WebM in high quality, go to https://www.ffmpeg.org/download.html and download it. You will acquire it as a .zip file. Now unzip the above file that you have downloaded to a folder. For instance, you can unzip to C:\ffmpeg, and inside that folder, the contents will resemble the image below.
Step 2: Start Video conversion
