OpenShot is a very easy-to-use video editor that anyone can understand. A large number of video and audio formats are supported, it is possible to insert transitions and use effects, both video (brightness, contrast, white balance, sepia, old film effect, etc.) and sound. It is possible to insert 3D titles created in Blender. The program easily integrates into the GNOME environment; files can be added to the project by simply dragging and dropping. Exporting files makes it easy to have ready-made profiles.

This is an alternative to commercial programs like FL Studio (R), which allow you to create music on your computer.
It includes creating melodies and beats, synthesizing and mixing sounds, and organizing samples.
You can have fun with the MIDI keyboard and much more, all in a convenient and modern interface.
