Free programs to improve the quality of a video

When we have to edit a video we cannot rely on the first program that Google gives us (perhaps all automatic or a trial of a much more expensive program) but we will have to use a program that allows us to act on different parameters, so as to improve the quality of a video without having to re-shoot (which is often impossible, especially if we have "seized the moment").
Among the parameters to get your hands on certainly stands out the volume (to be optimized), the removal of the blur effect (to make it more defined), the cutting of a few too many scenes, the addition of additional scenes but also adding effects or increasing them. the resolution of the final video. Some of these jobs can be easy, others rather complicated if we don't use the right program.
Not wanting to bother with professional-grade and consequently very expensive programs, in this guide we will show you the best free programs to improve the quality of a video that we can download on PC; in addition to the programs in the strict sense we will also show you the Web apps, ie video editing programs accessible directly from the browser without installing anything on your computer.
