This app can convert MKV files to M4V (MP4/MOV) files. It is very fast because “it converts only audio tracks” but does not convert a video track. (it just copy a video track.) For the same reason, it can convert while preserving the original quality of the source video track. And if it has a SRT file, it is available to insert a closed caption.
MKV, FLV files can be converted to M4V, MP4 or MOV. (Sandbox*)
• Also, it can use MKV2M4V as a simple media info app. And if the source video track's codec is supported in the m4v (mp4/mov) container, it can convert that.
• If the format filter is ‘ALL’,
- Following formats can be opened: mkv, flv, mp4, m4v, mov, avi, ts, tp, trp, wmv, rmvb, mts, m2ts.
- If it opens the folder that includes 'BDMV', it will automatically search 'm2ts' files in 'BDMV'.
• Audio for 'Mac', 'iOS Device', 'Apple TV'.
• It can use 'Mac' preset for the playback on 'iOS devices’/‘Apple TV' via the iTunes's 'Home Sharing'.
'Closed Caption' (Sandbox*)
• If it has a SRT file, it is available to insert a closed caption to the converted file. (up to 2)
• Source srt files should be in the same folder as the video file or in MKV2M4V’s the place to save.
• Source srt files should have a name like this; ‘video_file_name’, ‘video_file_name*’.
• Supported text encodings are UTF-8, UTF-16.
'Internal Subtitles Extraction'
• It currently supports only the internal subtitle that is recognized as 'SSA', 'ASS (Advanced SubStation Alpha)’, ‘SUBRIP’ type.
'Audio Preview' support.
'Automator' support. (Sandbox*)
'Move to Trash' support.
• Two audio tracks in the one source file can be used for the conversion with the 'Custom' mode.
- Depending on the supported audio codec of the media playback app, the converted file with only AC3 audio tracks may be not played normally.
• It is available to add a second audio track encoded with AAC for the one source audio track.
• Pass-through option works only if the source audio codec is supported in the target's file format.
• It normalizes audio volume if it is not ‘Pass-through’.
• ALAC option only works with M4V or MOV file format.
• AAC option's bitrate is up to 320Kbps.
• If the source video track is not H.264 codec, it may be not converted normally.
• The copied video track may not be supported on the OS's default media feature according to the H.264 settings of the source video track.
- For example, the video track with 'yuv420p10le' (yuv420p 10-bit) pixel formats or interlaced frames is not supported on the OS's default media feature.
• If the video track has wrong timestamps and is encoded with H.264/YUV420P/Progressive, it will attempt to repair it.
It can get more informations about these features at 'MKV2M4V Support'.
* Related to ‘Sandbox’
- As for ‘MKV2M4V’ app, if it opens not folders but video files, srt files should be in the following folders or its subfolders to use them automatically. If not, it should open it manually;
- As for ‘Add and Convert’ action, because ‘Automator’ doesn’t support ‘Sandbox’, video and subtitle files (folders) should be in (be) the following folders or its subfolders;
- Folders that once opened while the app is running, MKV2M4V’s the place to save.
※ MKV2M4V is a front-end to 'FFmpeg', 'MP4Box' licensed under the LGPLv2.1. Also MKV2M4V uses some dynamic libraries of 'FFmpeg' licensed under the LGPLv2.1. It can get more informations about 'FFmpeg' (http://ffmpeg.org), 'MP4Box' (http://gpac.wp.mines-telecom.fr/mp4box).
• Fixed the issue that os type options are not applied to the closed caption.
• Fixed other minor bugs.
• Improved parsing for ASS/SSA format.

Best 3 Dollars I've Spent in the App Store Thus Far - This app does EXACTLY what I want it to do: It converts my MKV backups of certain media to MP4(M4V.) No video reencoding. (I have Handbrake for when I need to do that.) Video is passed through losslessly. But what's REALLY great (for me) is that I can pass through the audio losslessly as well. That's a welcome feature I was not even expecting. The option is also there to convert the original AC3, 5.1. etc. to AAC @160 Kbps (required for playback on most devices like the iPhone, iPad, and iPod Touch.) This works also with encoded video files that are already lossy (like Handbrake rips.) "Pass through" means there will be no generational loss of quality from the source. Source-to-lossy is one thing, but lossy-to-lossy is generally a bad idea and will turn your video and audio files into poor-quality sonic/visual garbage. Conversion is very fast. It's not like reencoding, say, a BD where you'd start it and go to sleep hoping it's done in the morning. Minutes. This program has a very simple and intuitive GUI. No shock and awe…it's utilitarian and all business. I'm pretty happy. I sort of gambled by paying to try it out, but I'm glad I did. I was sick of searching the web for outdated programs that don't even come close to this sort of simple functionality. They are seemingly nonexistent anyway. I would give it six stars if I could due to MKV2M4V's usefulness to me and also the fact that I've not experienced a single problem with it.
I demand a refund - User interface is just awful, took me 10m to only start converting, convertion takes hours, and even when the convertion is over I've got 3 files, 1 video and 2 audio files! I am really disappointed from this! I DEMAND a refund!
