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 <a href="https://kdenlive.org/en/">Kdenlive</a> 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 <code class="language-plaintext highlighter-rouge">ffmpeg</code> a shot.</p> <h2 id="let-the-show-begin">Let the show begin</h2> <p>Like Kdenlive, I have never used <code class="language-plaintext highlighter-rouge">ffmpeg</code> before. Like every normal Linux user do, I opened up a terminal and typed <code class="language-plaintext highlighter-rouge">man ffmpeg</code> to learn how to use it… Just kidding :D I opened a browser and typed <em>“ffmpeg cut video by time”</em>. Not the best search query, but it was good enough to find what I am looking for as the <a href="https://stackoverflow.com/questions/18444194/cutting-the-videos-based-on-start-and-end-time-using-ffmpeg">first result</a>.</p> <h3 id="cutting-the-videos-based-on-start-and-end-time">Cutting the videos based on start and end time</h3> <p>According to answers on the page I mentioned, I run the following commands to cut my video into two parts:</p> <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ffmpeg <span class="nt">-ss</span> 00:00:00 <span class="nt">-to</span> 00:01:55 <span class="nt">-i</span> input.mov <span class="nt">-c</span> copy part1.mp4 <span class="c"># take from 00:00 to 01:55</span> ffmpeg <span class="nt">-ss</span> 00:02:03 <span class="nt">-to</span> 00:05:17 <span class="nt">-i</span> input.mov <span class="nt">-c</span> copy part2.mp4 <span class="c"># take from 02:03 to 05:17</span> </code></pre></div></div> <p>These two commands run <strong>instantly</strong>! Kdenlive was still rendering… The progress was 46%. Meh… I said “Duck it, I am gonna use ffmpeg only” and cancelled the rendering.</p> <h3 id="concatenating-the-video-files">Concatenating the video files</h3> <p>Now we have two videos that we want to join. Guess what will be our next search query? <em>“ffmpeg join videos”</em>. And <a href="https://stackoverflow.com/questions/7333232/how-to-concatenate-two-mp4-files-using-ffmpeg">here</a> is the first result:</p> <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nb">echo </span>file part1.mp4 <span class="o">>></span> mylist.txt <span class="nb">echo </span>file part2.mp4 <span class="o">>></span> mylist.txt ffmpeg <span class="nt">-f</span> concat <span class="nt">-i</span> mylist.txt <span class="nt">-c</span> copy result.mp4 </code></pre></div></div> <p>And we are DONE! How easy was that? Whole process took about 10 minutes including my search on the internet. If I continued waiting for Kdenlive to finish rendering, I would probably be still waiting at that time. I love the power of command line!</p> </section> <footer class="page__meta"> <p class="page__date"><strong><i class="fas fa-fw fa-calendar-alt" aria-hidden="true"></i> Updated:</strong> <time datetime="2022-01-21T20:40:00+00:00">January 21, 2022</time></p> </footer> <section class="page__share"> <a href="https://twitter.com/intent/tweet?text=Using+ffmpeg+for+Simple+Video+Editing%20https%3A%2F%2Fsahinakkaya.dev%2F2022%2F01%2F21%2Fffmpeg-to-rescue.html" class="btn btn--twitter" onclick="window.open(this.href, 'window', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" title="Share on Twitter"><i class="fab fa-fw fa-twitter" aria-hidden="true"></i><span> Twitter</span></a> <a href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fsahinakkaya.dev%2F2022%2F01%2F21%2Fffmpeg-to-rescue.html" class="btn btn--facebook" onclick="window.open(this.href, 'window', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" title="Share on Facebook"><i class="fab fa-fw fa-facebook" aria-hidden="true"></i><span> Facebook</span></a> <a href="https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fsahinakkaya.dev%2F2022%2F01%2F21%2Fffmpeg-to-rescue.html" class="btn btn--linkedin" onclick="window.open(this.href, 'window', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;" title="Share on LinkedIn"><i class="fab fa-fw fa-linkedin" aria-hidden="true"></i><span> LinkedIn</span></a> </section> <nav class="pagination"> <a href="/2022/01/04/build-and-deploy-automatically.html" class="pagination--pager" title="Automatically Build and Deploy Your Site using GitHub Actions and Webhooks ">Previous</a> <a href="#" class="pagination--pager disabled">Next</a> </nav> </div> </article> <div class="page__related"> <h4 class="page__related-title">You May Also Enjoy</h4> <div class="grid__wrapper"> <div class="grid__item"> <article class="archive__item" itemscope itemtype="https://schema.org/CreativeWork"> <h2 class="archive__item-title no_toc" itemprop="headline"> <a href="/2022/01/04/build-and-deploy-automatically.html" rel="permalink">Automatically Build and Deploy Your Site using GitHub Actions and Webhooks </a> </h2> <p class="page__meta"> <span class="page__meta-date"> <i class="far fa-fw fa-calendar-alt" aria-hidden="true"></i> <time datetime="2022-01-04T17:40:00+00:00">January 4, 2022</time> </span> <span class="page__meta-sep"></span> <span class="page__meta-readtime"> <i class="far fa-fw fa-clock" aria-hidden="true"></i> 5 minute read </span> </p> <p class="archive__item-excerpt" itemprop="description">In this post I will explain how you can use GitHub to automate the build and deployment processes that you have.
