Convert MKV to QT?

Question

I did search but cannot find anything that specifically addresses the proble of "converting" MKV files to QT.
I can play the mkv's that I have using videolan, or MPlayer, but I want to be able to get them into a QT format. I have QT 7 Pro; I also have Flip4Mac which handles WMV conversions very well. But not, it seems, mkv.
Any help with converting? Thanks

This is command line only....

The decision about the output format is based on the track type, not on the extension used for the output file name. The following track types are supported at the moment:
V_MPEG4/ISO/AVC
H.264 / AVC video tracks are written to H.264 elementary streams which can be processed further with e.g. MP4Box from the GPAC package.
V_MS/VFW/FOURCC
Fixed FPS video tracks with this CodecID are written to AVI files.
V_REAL/*
RealVideo tracks are written to RealMedia files.
A_MPEG/L3, A_AC3
These will be extracted to raw MP3 and AC3 files.
A_PCM/INT/LIT
Raw PCM data will be written to a WAV file.
A_AAC/MPEG2/*
All MPEG2 AAC files will be written into an AAC file with ADTS headers before each packet.
A_AAC/MPEG4/*
All MPEG4 AAC files will be written into an AAC file with ADTS headers before each packet. The ADTS headers will not contain the deprecated emphasis field.
A_VORBIS
Vorbis audio will be written into an Ogg/Vorbis file.
A_REAL/*
RealAudio tracks are written to RealMedia files.
A_TTA1
TrueAudio tracks are written to TTA files. Please note that due to Matroska’s limited timecode precision the extracted file’s header will be different regarding two fields: data_length (the total number of samples in the file) and the CRC.
S_TEXT/UTF8
Simple text subtitles will be written as SRT files.
S_TEXT/SSA, S_TEXT/***
SSA and *** text subtitles will be written as SSA/*** files respectively.
Tags are converted to a XML format. This format is the same that mkvmerge supports for reading tags.
Attachments are written to they output file as they are. No conversion whatsoever is done.
Chapters are converted to a XML format. This format is the same that mkvmerge supports for reading chapters. Alternatively a stripped-down version can be output in the simple OGM style format.
Timecodes are first sorted and then output as a timecode v2 format compliant file ready to be fed to mkvmerge. The extraction to other formats (v1 and v3) is not supported.
EXAMPLES
Let’s assume you’ve made a Matroska file with one video track, two audio tracks and two subtitle tracks, and you need the second audio track and the first subtitle track. So first fire up mkvmerge with the --identify option:
$ mkvmerge -i movie.mkv
File ’movie.mkv’: container: Matroska
Track ID 1: video (V_MS/VFW/FOURCC, DIV3)
Track ID 2: audio (A_MPEG/L3)
Track ID 3: audio (A_VORBIS)
Track ID 4: subtitles (S_TEXT/UTF8)
Track ID 5: subtitles (S_TEXT/UTF8)
Now you can call mkvextract like this:
$ mkvextract tracks movie.mkv 3:audio.ogg 4:subtitles.srt
Another example. Let’s assume you have a Matroska file with one RealVideo v10 track, one Vorbis audio track and one RealAudio (COOK) track. The identification output might look like this:
$ mkvmerge -i movie2.mkv
File ’movie2.mkv’: container: Matroska
Track ID 1: video (V_REAL/RV40)
Track ID 2: audio (A_VORBIS)
Track ID 3: audio (A_REAL/COOK)
Let’s further assume you want only need the video and the RealAudio track but both in the same output file. This is possible for RealMedia files by using the same output name for those tracks that you want to end up in the same file:
$ mkvextract tracks movie2.mkv 1:extracted.rm 3:extracted.rm
Sometimes the raw data of a track might even be useful, e.g. for MPEG-1 tracks. In this case you can use a track flag like this:
$ mkvextract tracks movie3.mkv --fullraw 1:extracted.mpeg
If you need the timecodes for all the blocks of track 2 from a file then you can let mkvextract create a timecode v2 format file like this:
$ mkvextract timecodes_v2 input.mkv 2:timecodes-track2.txt
