<p>FFmpeg is a powerful tool for manipulating audiovisual files. Unfortunately, it also has a steep learning curve, especially for users unfamiliar with a command line interface. This app helps users through the command generation process so that more people can reap the benefits of FFmpeg.</p>
|
||||
<p>Each button displays helpful information about how to perform a wide variety of tasks using FFmpeg. To use this site, click on the task you would like to perform. A new window will open up with a sample command and a description of how that command works. You can copy this command and understand how the command works with a breakdown of each of the flags.</p>
|
||||
<p>For FFmpeg basics, check out the program’s <a href="https://www.ffmpeg.org/" target="_blank">official website</a>.</p>
|
||||
<p>For instructions on how to install FFmpeg on Mac, Linux, and Windows, refer to Reto Kromer's <a href="https://avpres.net/FFmpeg/#ch1">installation instructions</a>.</p>
