<h5>Making FFmpeg Easier</h5>
<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>

<h3>Join files together</h3>
<p><code>ffmpeg -f concat -i mylist.txt -c copy [output] </code></p>
<p><code>ffmpeg -f concat -i mylist.txt -c:a copy -c:v copy <i>output_file</i></code></p>
<p>This command takes two or more files of the same file type and joins them together to make a single file. All that the program needs is a text file with a list specifying the files that should be joined. However, it only works properly if the files to be combined have the exact same codec and technical specifications. Be careful, ffmpeg may appear to have successfully joined two video files with different codecs, but may only bring over the audio from the second file or have other weird behaviors. Don’t use this command for joining files with different codecs and technical specs and always preview your resulting video file!</p>
