Quicktime Player is a simple video recorder and editing app which is included on Mac computers and available as a paid app upgrade on PCs. It is a small program, so it loads up quicker than more powerful video editors such as iMovie.
Quicktime Player is useful for:
recording the screen or a part of the screen
recording from the webcam
recording audio
trimming movies
reducing the size/resolution of movies
Use a spotlight search for Quicktime on your Mac
Quicktime Player will load, and the menu bar will change to display options.
Choose File and select the option required.
When you have finished recording, Save the file or export as to specify a format.
