 &lt;p&gt;Today, I have recorded a video for one of my classes and I was required to upload it till midnight. The video was perfect except for a few seconds where I misspelled some words and started again. I had to remove that part from the video before uploading it. Since I was low on time, I thought that I better use a GUI program to do this job. I opened up &lt;a href=&quot;https://kdenlive.org/en/&quot;&gt;Kdenlive&lt;/a&gt; and jumped into editing my video. It was my first time using it so I spent some time to cut and delete the parts that I want to get rid of. When I was ready, I clicked Render button to render my video. It was waaay too slow than I expected. Since I have nothing to do while waiting for render to finish, I thought I could give &lt;code class=&quot;language-plaintext highlighter-rouge&quot;&gt;ffmpeg&lt;/code&gt; a shot.&lt;/p&gt;
