HandBrake was originally created in 2003 by the Eric Petit who made this app exclusively for the shortly lived BeOS operating system, but was shortly after ported to Windows, macOS and Linux (Ubuntu). You can apply many great video filters (grayscale, detelecine, decomb, deinterlace, denoise, deblock), as well as set the video codec, quality and framerate, audio codec, mixdown, sample frequency rate and bitrate.
Of course, the app fully supports one of the most popular video conversion processes of all time -transfer of movies from your DVDs to your hard drive by converting them to files in the MPEG-4 format.
It enables anyone to easily prepare their camera videos to be played on a wide variety of devices, including all versions of iPhones, iPads, Apple TVs, Android phones, Android tables and more.
HandBrake for Mac is a free and open source tool for converting video files from nearly any format to a selection of modern, widely supported codecs.
