Important: If your Mac's operating system is version 10.15 or newer, then install Elmedia Player instead of VLC. To check your Mac OS: Click on the Apple icon in the top left, select 'About This Mac', then the version will be at the top listed under the MacOS name (Catalina). VLC is free, safe, and has a easy frame-by-frame option. The other versions of VLC cause the frame-by-frame to freeze, so download version 2.2.8 and do not install newer versions. There is an alternative to Elmedia Player for Mac users called VLC Media Player Version 2.2.8.
