<h3>Trim</h3>
<h3>Excerpt from beginning</h3>
<p><code>ffmpeg -i <i>input_file</i> -t <i>5</i> -c copy <i>output_file</i></code></p>
<p>This command trims the beginning and end of a video file without re-encoding</p>
<p>This command captures a certain portion of a video file, starting from the beginning and continuing for the amount of time (in seconds) specified in the script. This can be used to create a preview file, or to remove unwanted content from the end of the file. To be more specific, use timecode, such as 00:00:05.</p>
