How to create educational videos. Some suggestions

Creation of educational videos
Continuing with our series of suggestions on open source tools that can help during the pandemic, we are going to dedicate this article and the next to the programs and web services that will be useful for creating educational videos.

What is an educational video

Educational videos are those that They are used to demonstrate, transfer knowledge, explain concepts, or show how to do something.

En this link from Youtube we have, for example, a mathematical proof.

An educational video can be used as much as a temporary substitute for class attendance as a way of teaching people to save moneyor doing your own repairs.

Types of educational videos

In the next article we will further develop some available tools. In the paragraphs that follow I quote some names with links to their website.

Some types of educational videos are

  • Micro procedural videos: They are short videos that focus on a specific task. For example make an Origami bird. For this type of video, the mobile camera is usually enough, but keep in mind that every time you record a vertical video, a kitten dies.
    You may need a conversion tool between formats such as Winff or the conversion wizard VLC.
  • Tutorials: In this type of video, what is explained is a procedure divided into a series of steps. For example a cooking recipe or the installation of a Linux distribution. This type of material requires a larger pre-production. If it is a question of demonstrating the use of a computer program, it is best to use a screen capture application, the best of which is OBS-Studio.
    In the case of a real-world tutorial, you will need a camera with more capabilities than the phone and a video editing program. For my taste the easiest to use is Opportunity.
  • Training Videos: They are videos designed for the viewer to execute the steps as they are seen. For example those who teach physical exercises. Its pre-production is much more complex and requires careful editing. You may need to record and process the audio separately. A good tool to do this is Audacity.
  • Explanatory videos; They are short videos in which concepts are developed without demonstrating them. Visual aids such as photos or graphics are often used. Any presentation program and a screen capture application such as the one mentioned can be used. OBS STUDIO.
  • Virtual class: It is the video recording of a face-to-face class. The camera's zoom can be used to record the content of the whiteboard, or take screenshots of programs that interact with graphics tablets such as  Xournal ++.

What you should keep in mind is that you are not filming the latest installment of The Fast and the Furious . You don't need the equipment of a Hollywood super production company. You just need a camera with a decent resolution, reasonable lighting, and equipment that supports rendering and screenshots. without slowing down the operation.
Gary Vaynerchuk, a successful video blogger specialized in wine and management recounts his beginnings;

On February 21, 2006, on a YouTube channel with zero followers, the world's first wine video blog was launched. Without fanfare, it started with a guy in a blue sweater - maybe it was black, bad lighting made it hard to tell - sitting in front of a plain beige wall. On the table in front of him sat three bottles of wine and a small, dark bucket that looked like it might once have been a flowerpot. Her skin was yellow from the sickly fluorescent light that barely illuminated her face, but she had a wide, optimistic smile. Looking directly at the Flip cam, he announced to his nonexistent audience in a soft, serious but friendly voice: "Hello everyone and welcome to the first episode of Wine Library TV."

Although the quote is a bit off topic, considering that we are talking about educational videos, it does serve to prove my point. Gary has more than a thousand episodes of his blog and although he improved his technology, the important thing is still the content.
