One and a Half Natures of Human Beings - Additional Materials. How to Record Video Lectures and Presentations? Advice on Software

Both students who need to give a presentation in a distance course and teachers preparing online lectures may find useful advice on free, open, cross-platform software that can be used for such work.

A software option that is free and cross-platform:
LibreOffice Impress is a program for creating presentations. It is a component of the free LibreOffice package, which is an analogue (in my opinion, a better one) of the closed and paid Microsoft Office. Impress is an analogue of PowerPoint. When the author worked with PowerPoint (this was quite a long time ago), it was difficult to insert high-quality video into it; switching to Impress removed these problems. Illustrations and diagrams can be created both in Impress and in Draw, which is part of the same package.
OBS Studio is a program for internet broadcasts and screen recording. It allows recording a presentation (with video and sound if necessary), the cursor position, the lecturer’s voice, and overlaying video from a camera showing the lecturer on the screen.
OpenShot Video Editor is an editing program. It allows assembling video from fragments, adding and removing sound, cutting and composing the video sequence (even cutting out an unsuccessful phrase or replacing it with another fragment).
GIMP (GNU Image Manipulation Program) is a raster image editor. Among other things, it makes it convenient to obtain a set of slides corresponding to a presentation (for example, to add them to a video recording of a presentation so that the slides themselves can be examined in more detail).
Audacity (with the LAME codec for working with mp3 format) is a free audio editor that, among other things, allows removing excess noise from a recording.
