A lot times when people record themselves, you see their eyes slowly drift down as they read through their script. An easy easy way to make it look like you know what your doing is to use a teleprompter app. It is not perfect, but at least it will keep your eyes in one place. For myself, I tried out two before settling.
Teleprompter by Nokse [link]
This is such a clean interface and very straight forward. I think Teleprompter fits right at home in a clean environment like Gnome. However, I am hoping to see more fine tuning control over the speed of the teleprompter, as I needed it to go just a little bit slower than it would allow me to lower the speed down to. I have opened a request on github for this, and hopefully the creator will be open to doing so, as I love the simplicity of Teleprompter.
QPrompt by Javier O. Cordero Pérez [link]
QPrompt does so many things. It can be complicated if you see the bar at the bottom and get overwhelmed, but it does not need to be. That is all stuff you can play with, but do not have to. Just click the little wrench icon and you can then adjust the “step acceleration,” or the speed of the prompter. This is what I ended up using for my needs, but I felt like this may be a lot for my simple needs. That being said, clearly a lot of effort went into QPrompt and it will probably serve more of the KDE mindset better. You have all the options you need, like opacity, alignment, velocity, countdown timers, backgrounds, and so on. If your like me, you can just paste your text in and set the speed and go as well. It should be noted that QPrompt runs on Linux, Windows, macOS, and Android.
