MKVtools v3.3.2 Mac OS X | 36 MB
MKVtools is a Mac OS X application used for the creation and editing of MKV videos. It is an update and more specialized version of the original MKVtools, so if you are familiar with its operation, you should be comfortable using this rebranded version.
As the name might imply, MKVtools is a graphical interface for a variety of tools useful for processing video files. Mencoder, Mplayer, and the binaries from Mkvtoolnix do the brunt of the work. Limitations to MKVtools' capabilities are most often due to limitations with these applications. When you open a video file in MKVtools, you will be presented with a list of video, audio and subtitle tracks contained in the file. Sometimes there will be enough information for you to determine what each track represents. If not, you can select a video and an audio track (and optionally a subtitle track) to preview the tracks in an mplayer window. Once you've determined which tracks you are interested in, you can either convert the tracks into an MKV video, or you can extract the tracks individually to manipulate in your favorite video application. You also can edit MKV files by either splitting or joining videos, or you can add tracks to the video.
