EDITOR NOTES
Version 2.0 is still free and available here.
DESCRIPTION
MKVtools is a collection of tools used to manipulate .mkv and .ogm video files. It's primary purpose is to convert .ogm and .mkv files into more user friendly formats - either .avi files, .mp4 files or as individually extracted track files. MKVtools is trialware - only $4.99 for full functionality, though it will function unregistered, with some minor limitations.
Key features include: - Convert .mkv and .ogm videos to either .avi files or .mp4 files.
- Extract the selected tracks as individual video, audio and/or subtitle files.
- Intuitively select desired video, audio and/or subtitle tracks to proces, with the ability to verify the selections using video preview.
- Use presets for one step encoding .mp4 files for playback on iphones/ipods.
- Though still a work in progress, use presets for one step encoding .mp4 files for playback on Apple TV/Playstation 3/Xbox 360.
- Embed selected subtitle track (i.e., hard subtitles) into the video.
- Control the font, size and positioning of the embeded subtitles.
- Split .mkv videos into sections of a specified file size or by start/end time.
- Delete tracks from .mkv files.
- Join, mux and change the pixel aspect ratio of .mp4 videos.
- Add jobs to a queue either individually or in batches via drag and drop so you can process multiple files overnight (registered copies only).
WHAT'S NEW
Version 2.1:
- can now mux tracks/files into .mp4 files
- can now split mkv files and join mp4 files which may prove useful for processing very large mkv files
- added the abiltiy to delete tracks from mkv files and change the pixel aspect ratio of mp4 videos
- improved video information gathering and checking
- improved muxing speed
- added pass thru video for mp4 conversions
- will change the avc level of passed thru h264 videos to 4.1 which may trick your device into playing the video without the need to re-encode
- added presets for Apple TV, PS3 and Xbox 360
REQUIREMENTS
Mac OS X 10.4 or later though may work on older systems. Power PC processors may have issues with converting to aac low complexity audio for ipod/iphone use.

BEIGE Beware - the license is tied to your machine so now I'm stuck using this on my mac mini...

JOSHMUNKEY This is a jack-of-all-trades application, but a master of very little when it actually comes down to it. The handling of .ogm files is wonderful to see, and the ease of file extraction really sings to me as I am constantly tinkering with the streams of my files, but there's so many bumps all over the place that leave me scratching my head, such as a lackluster interface and feature set when actually converting files (a lack of automatic bitrate calculations becomes a bother, as well as the half-assembled height/width bar that leaves some of my .h264 files oddly squished when the original file under Quicktime has differing normal size and current size, natively). In a way I suppose that I keep coming back to this application because the more efficient and robust ffmpegx has all but kicked the bucket and I am hoping to see the same sorts of innovation that that old and decaying application brought, but... maybe they are just two separate and differing things all together. It's a sad feeling knowing that I need to jump to a Windows partition to do even the most rudimentary of tasks with AVC files if I want exacting quality, but it just seems that for now that is the way it is.

AIKOUSHA I don't know what form of mkv files those who gave this a 5 were converting, but it wasn't x264 based... I've been trying this on and off since it was version 1 of mokgvm2DVD. I had EXACTLY one conversion come through correct and easily on the video portion, but the subtitles were screwed up (tiny with no way to change the size or position, yup I know about the options button). However, probably not due to the GUI or tools in this package, it can't cleanly convert any of the stupid matroska files I need to convert. I actually have to give these to people outside the company to deal with. The video that results from this and it's previous versions have stalls, drop outs, jumping blocks and in ALL cases now, have a really bizarre form of horizontal digital streaking. My guess this is due to a popular windows x264 (not a compliant H264) codec that has no Mac/Unix/Linux equivalent, and it screws up like this due to improper header information and something critical in the actual image processing that is not completely compliant with H264. On top of that, nothing I have given this new version (MKV Tools), can even get the subitles to burn into the video. Since everything I deal with has subtitles of one form or another, this is a deal breaker. I do like the fact that matroska files converted with this maintain audio sync correctly, even though there isn't a single player out there that can maintain sync while playing the mkv files I deal with, live. I'm sorry I can't give this a recommendation, even if the main problem is most likely with the idiots on the Windows encoding side, but a Matroska converter that can't convert matroska files to make them watchable (regardless of whose fault it is), is fairly useless.

EMMGUNN Not true. See here - http://www.gnu.org/philosophy/selling.html - which specifically discusses the selling GPL code.

FROMAGE-HEAD "mokgvm2DVD had trouble determining how long your video is. Enter the lenght (in second)" Is it a joke ?

JDUB800 This doesn't make playable DVDs. Who wants to use MPEG-2? I certainly don't...

ANDY49 I don't know how many people know this, but Roxio Toast 8 and 9 converts and burns these files perfectly into playable DVD's. No need for this.

TRONDAH You are aware that this app is $3.50 while Toast Titanium is $99.99 right?

ANDY49 This does not convert mkv files on 10.5. It says complete within seconds.

HAGOUN Mplayer is able to read mkv files quite well (containing rv9/10, h264 or wm9 video track). Just download last xcode package to compile it. Otherwise, nice to extract subtitles and other extras from mkv files

DOUG S. Thank god someone finally did this! I'm sick of getting Matroska files when I download fan-subs and having to watch them in VLC player. Now I can use them all in Front Row! Features: It does everything you'd want it to do and then some, giving you lots of options to have the final product suit your tastes perfectly. Ease of Use: You just drop in the files, select the parts you want, and either extract or export. It's that easy. Value: It's free. What's better than free?! Stability: I've not used it extensively as of yet but from what I've seen it runs perfectly smoothly.

DOUG S. OK I've used it much more extensively now so count this as an extension of my review. I've noticed two minor glitches. (1) With subtitles changing the size they're supposed to be when embedded, at least on some of the MKVs I've been using, doesn't actually change the size when I got to test. (2) Sometimes the sound is lower than the original output. This is a rare occurrence but still a bit of an annoying one. Otherwise every MKV and OGM I've tossed at it it's spat out in pretty good time while giving me now audio/video sync issues and being 100% stable.

MIKURO In case you don't know, Perian lets QuickTime-based apps (that includes Front Row) the ability to play MKV files. It also has great subtitle rendering which puts VLC to shame. I haven't used this app yet. It certainly does sound promising, Perian or no Perian. There's no way to play OGMs in QuickTime, and few (if any) MPEG4-compatible DVD players support MKV or OGM.

DOUG S. I am indeed aware of Perian and have been for quite some time. There are other plugins as well that support MKVs and OGMs but I just haven't played with Quicktime's subtitle functions that much in how they render. I'm curious to find out what settings it has that I can mess with, if any.
