It is often useful to record the activity on your screen. Gamers do it to share and impress others on their game skills. Instructors do it to illustrate the things they are teaching. It is very useful as documentation, troubleshooting, and more

The process is to first select what area of the screen to record; the entire screen, a specific region, or a specific window. You can usually also select the sound source and many of the details of the type of file format and processing options.

Once configured, you would start the recording process. While recording you would perform whatever tasks on screen you intend or want captured, all while narrating the process.

Once you have recorded the material you want, you would stop the recording and save it to a file.

That file can then be edited (sound and/or video) using a program like Kdenlive. Kdenlive not only allows you to edit the video in great detail, it allows you to then save it to other file formats such as wav and mp4.

Windows 10/11 have several tools available for screen recording.

Install SimpleScreenRecoder

$ sudo apt install simplescreenrecorder

When launched, you will see the title window. Click 'Continue' at the bottom to continue.

Here you can select 'Record the entire screen', or more often you would click the 'Select window...' button followed by clicking on the window you want recorded. At the bottom you can select the audio input, the sound source. If the default does not work, you will need to select a different 'Backend', and/or the 'Source'.

Now click 'Continue'

On this next screen set the 'Save as' line to the path and filename you want to save the recording to. Go ahead and use the 'Matroska' 'Container'. You can convert this to mp4 or what ever later with Kdenlive.

Click 'Continue'

This screen will show you what you have configured. When you are ready, click 'Start Recording' at the top to record the portion of the screen you have selected. When you are done recording, click 'Pause' to stop the recording. These two are displayed in the same location, the button title simply changes.

When you are done, click the 'Save recording' button at the bottom right.

You can now work with the saved file in Kdenlive or other tools.

Rather than document the current details, which seem to change with each OS version, you should check the documentation for your OS to see how to take a screenshot and save it as an image file.

Besure of what you saved your video or image file to. You will want to move it to where ever you are working on your project.

And on that topic, for each project (creating a video in this case) you should create a new directory that is descriptively named for that project. That is where you should gather all image, video, text, temp, or any other type or file associated with that project. This is also where you should do all your work on that project.

Be sure that this and any other projects are backed up regularly! And that means to copy the everything to another media (USB drive, Internet file server, something other than the computer you are working with).
