HandBrake is a handy tool that enables you to convert almost any video file or DVD to MP4 or MKV format. This means that you can import DVDs to files on your hard drive (depending on the protection used on the disc), as well as convert video files to different format. You can apply video filters (grayscale, detelecine, decomb, deinterlace, denoise, deblock), as well as set the video codec (H.264, H.265, MPEG-4, MPEG-2, VP8, Theora) frame rate and quality, audio codec (AAC, HE-AAC, MP3, AC3, OGG), mixdown, sample frequency rate and bitrate.
