What is HandBrake? What can you do with it?


HandBrake is an open source video conversion program. It can read from DVDs, video files, and other video sources. It also produces video files in a wide variety of formats.
Supported Sources:
Any DVD-like source: VIDEO_TS folder, DVD image or real DVD (unencrypted--protection methods including CSS are not supported internally and must be handled externally with third-party software and libraries), and some .VOB and .TS files
Most any multimedia file it can get libavformat to read and libavcodec to decode.
Outputs:
File format: MP4 and MKV
Video: MPEG-4, H.264, or Theora (1 or 2 passes or constant quantizer/rate encoding)
Audio: AAC, MP3, Vorbis or AC-3 and DTS pass-through (supports encoding of several audio tracks)
Features
Encoding
Users are able to customise the output by altering the bit rate, maximum file size or bit rate and sample rate via "constant quality".
HandBrake supports batch encoding through the Mac OS X, Linux and Windows graphical user interface (GUI) and command line interface (CLI). Third party scripts and UI’s exist specifically for this purpose, such as HandBrake Batch Encoder and VideoScripts. Both make use of the CLI to enable queueing of several files in a single directory.
Video filtering
HandBrake also supports deinterlacing, decombing, scaling, detelecine, and cropping.
DVD
HandBrake’s developers removed libdvdcss (the open-source library responsible for accessing and unscrambling DVDs encrypted with the Content Scramble System (CSS)) from the application in version 0.9.2. Removal of digital rights management (DRM) in HandBrake is possible by installing VLC, a media player application that includes the libdvdcss library.
Blu-ray Disc
As with DVDs, HandBrake does not directly support the decryption of Blu-ray Discs. However, HandBrake can be used to transcode a Blu-ray Disc if the digital rights management is first removed using a third party application, such as MakeMKV. MakeMKV is a popular application for decrypting Blu-ray Discs and is often used in conjunction with HandBrake.
Unlike HandBrake, MakeMKV does not transcode; it removes the digital rights management from a Blu-ray Disc and creates an exact copy, at its original frame size and data rate, in a Matroska (MKV) multimedia container which can then be used as a source in HandBrake.
