Pingou's weblog, his fedora's news, his RPMs, his tests, his Linux... :-)2022-02-17T10:46:15+01:00pingouurn:md5:66db5ce1ed1a80cb2f424695b4bb7780DotclearScreencast and editingurn:md5:fed2159c8debdafb97fdd09ccdea5f292021-06-08T16:01:00+01:002021-06-08T16:29:52+01:00Pierre-YvesGénéralDocumentationFedorascreencastvideo editing <p>Recently I have had to prepare a couple of demo about some work I have been doing. As my internet connection isn't the fastest, I chose to do a screencast that I could then upload somewhere and share. This prevented issues with my internet as well as gave me the possibility to show the full thing by editing the recording.</p>
<p>However, I ran into a few problems.</p>
<p>I first tried quite a few screencast apps:</p>
<ul>
<li>The screencast tool that is built-in in gnome (simply pressing ctrl+alt+shift+r). However, this is recording only very short screencast by default, changing this default meant editing a configuration value in dconf (and thus having some idea beforehand of how long the recording will be).</li>
<li>recapp, that one simply didn't start me for</li>
<li>peek, that one seemed to work but intercepted all my mouse clicks, so I could only navigate with the keyboard, could not highlight anything with my cursor and when I looked at the recording, it was all black</li>
<li>SimpleScreenRecorder, could not seem to be stopped once started</li>
<li>OBS studio, recorded a black screen</li>
</ul>
<p>After all this, I gave up and re-log into my session using X11 instead of Wayland. Suddenly all of the screencast app worked fine... :)</p>
<p>So once I was able to record what I wanted to show, I still had over 10 minutes of video to show at a demo review, so I wanted to edit it, cut the parts where there are no progress, increase the speed of the parts where things are happening but do not need to be shown real-time (for example, when a system boots, or when it is being installed, if the speed there is x2, it is fine).</p>
<p>I've looked around at different tools and found:</p>
<ul>
<li>kdenlive</li>
<li>VidCutter</li>
<li>Video Trimmer</li>
<li>ShotCut</li>
</ul>
<p>I ended up settling for kdenlive for two reasons:</p>
<ul>
<li>someone I know uses it and recommended it to me (thus I knew it is able to do what I was looking for)</li>
<li>I've found this tutorial on youtube explaining me exactly how to do what I wanted to do:</li>
</ul>

<p>The kdenlive UI changed a little bit since this video was recorded (like the "Change speed" button is now available via a "right click" on the video track) but this tutorial is enough to give you some basis on video editing with kdenlive.</p>
