<h5>Making FFmpeg easier</h5>
<p>FFmpeg is a powerful framework for manipulating audiovisual files. Unfortunately, it also has a steep learning curve, especially for users unfamiliar with the command line. This app helps users through the bash command generation process so that more people can reap the benefits of the FFmpeg library. </p>
<p>This project is very much a work in progress. Each button displays a form to help fulfill a popular user request. To use, click on the button and fill out the form. After clicking the Generate button, a command line will appear in the box below. That line can be copied and pasted into a Terminal, with the assumption that the video file is located in the same directory that the user currently is in.</p>
<p>For FFmpeg basics, check out their <a href="https://www.ffmpeg.org/">official website.</a></p>
<p>For bash and command line basics, try the <a href="http://cli.learncodethehardway.org/book/">Command Line Crash Course</a></p>

<li>-vf fps=fps=1/60: -vf is an alias for -filter:v, which creates a filtergraph to use for the streams. The rest of the command identifies filtering by frames per second, and sets the frames per second at 1/60 (which is one per minute).</li>
<li>out%d.png: Names the output file. The %d is a regular expression that adds a number (d is for digit) and increments with each frame (out1.png, out2.png, out3.png…)</li>
