Description

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.


Features

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 Preset'
• 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.

Audio
• 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.

Video
• 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.

Ratings and Reviews

Works well on limited cases only

marchetype

Works well but some limitations need to be addressed. First, if video is in H265 HEVC, although the app should just be copying the video stream, the output file produced is unplayable.
Second, I have not found it possible to select any of the subtitle tracks in the input to have them copied to output. Third, it’s not clear in the interface, but you have to select Custom profile in order to process more than one audio track. Finally, after a conversion, it’s not possible to change the settings and convert the same file again: have the shut down and restart the app. This app has potential but it obviously in need of an update.

Good thinking!

Visualhub was what I used before, but after Lion it's been tricky to use even with the manual updating.. It always frustrated me that the difference between MKV and M4v were minor, I just wanted a program that merely changed the jackets and encoded the audio different, and $2 for a nice simple interface to do it, and the fact its on the App Store, i feel i can trust it in some ways.. I'll gladly pay that over some $15 nonsense that comes up in google. Only real comment, is it would be nice to be able to drag multiple files into the source area. Otherwise was exactly what i was looking for, and is obviously faster than Visualhub.. i'm sure there is some other method to do this for free.. but when you're tired and about to go on a flight, and just want to convert MKVs for your iPad, and you aren't the most clued up geek.. what else can you do.. good thinking whoever made this app, and decided to price it at $2!

Subtitles .ttf files locked?

Transcoding an MKV to an M4V or MP4 works great. This app does that job well and it does that job fast. On my last review, I noted that the subtitle support did not work. This has been fixed - for the most part. Many animes and movies use a .ttf file to give their subtitles a font, font size, and look to them. These .ttf files are visible in the options, but are unable to be selected. Not being able to convert with these files results in videos with large, obtrusive subtitles - because the app uses default subtitle settings. I really hope this gets fixed - then this app will be PERFECT and I will be happy to give 5 stars and recommend it to everyone I know. I hope this gets fixed soon.
