MKV2MP4 1.2.10

convert MKV videos to more compatible MP4 files

MKV2MP4

MKV2MP4 is an application that can convert video files in the MKV container format to more compatible MP4 video files. MKV2MP4 can convert most common MKV files very quickly and has a queue for converting hundreds of files at once. MKV2MP4 can be configured to either produce files with perfect compatibility (at the expense of conversion speed) or to do conversion extremely quickly by producing files that are playable on most, but not all players (see F.A.Q.). Because MKV2MP4 doesn't re-encode the video track, conversion is fast and the resulting video has the exact same high video-quality as the source file. Note that most subtitles are supported (see F.A.Q.) but some players do not display them.

Usage:

0.) Download MKV2MP4 from the „Mac App Store“ and once it has finished downloading start it from Launchpad or your Applications folder.

1.) Drag the MKV file(s) you want to convert onto the MKV2MP4 icon in the Dock or onto its main window

2.) Select the audio-track to convert and press the „Start Conversion“ button

Hint: Leaving the „Destination“ popup at „Ask…“ will ask you for the file destination when clicking „Start Conversion“. You can also select destination folders like you Movies or Downloads folder.

BATCH CONVERSION: In the preferences you can opt to start converting files as soon as they are dropped, which could be helpful for converting a very large number of files. For best results select a default destination folder for converted files and make sure the default audio language matches your preference.

HIGH SPEED CONVERSION: Note that conversion can be much faster if you select „High Speed & Quality“ in the „Audio Conversion Settings“ in the Preferences. The resulting files will play perfectly on most devices & players, but on some devices the files will not play or only play without sound (e.g. iOS devices). Just give it a try and leave it on if your target device supports it.

FAQ

  1. On what devices can i play the converted video files? 

    The converted files are compatible with every device and player that can play MP4 files (Video Players on Mac/PC, Smart TVs, Gaming Consoles, iPhone/iPad etc). 
    Downscaling:
    The only exception is that some devices play MP4s, but not of any resolution. For example, the iPhone 3G will not play full HD videos. The iPhone 5 plays HD videos converted by MKV2MP4 fine.
    Since MKV2MP4 does not do video downscaling, it is not suited for converting HD videos for playback on devices that don't support HD resolutions (like the iPhone 3G).
    If you change MKV2MP4 preferences to do a faster but less compatible conversion, the resulting files will still play perfectly on most devices/players (PS3, VLC, QuickTime), but not everywhere (notably not on iOS devices).

  2. What limitations does MKV2MP4 have? Are all audio-tracks and sub-tiles converted?

    Limitations:
    • MKV2MP4 does not do video downscaling, it is not suited for converting HD videos for playback on devices that don't support HD resolutions.
    • Some files (that contain too many ref-frames, 10-bit video or are larger than FullHD) will not play on some devices like the PS3 that don't support these features.
    • Some rare MKVs contain video in non-standard formats like VP9, these videos will fail to convert or play.
    • At this time MKV2MP4 only converts the selected audio track from the MKV to the MP4 file. All additional audio tracks are discarded. (Exception, there is the option to include additionally a 5.1 surround channel of the selected language, if available).
    • Some (image-based) subtitle formats are not transcoded (see subtitle question) and even subtitles that are properly converted may not be displayed on some devices that do not support subtitles embedded in MP4 files (like the PS3).

  3. Does MKV2MP4 support subtitles?

    Yes, most subtitle formats are supported, and converted into proper native MP4 subtitles, however some players/devices will not display subtitles in MP4 files (notably the PS3). The subtitles display properly in more standards-compliant video players (like VLC and MPlayer).
    Note that you currently have to explicitly enable conversion of embedded subtitles from the preferences because this can cause conversion to fail under rare circumstances.
    Note that Apple's devices and players like QuickTime only show subtitles for files with the M4V extension, there is a preferences setting to use the M4V extension by default.
    To convert subtitles they must either be embedded in the MKV file or be located in another file in which case they will only be picked up if:
    • the subtitle file has to contain the name of the MKV (but can contain suffixes like ‚.en‘, ‚-eng‘ or ‚-forced‘) and
    • the subtitle file is located in the very same folder (as the MKV) and
    • the subtitle file is dropped onto MKV2MP4 (together with the MKV file)
    Supported subtitle formats: 
    • SubRip (.srt)
    • SubViewer (.sub)
    • MicroDVD (.sub)
    • SubStation Alpha (.ssa / .ass)
    • SAMI (.smi)
    Other subtitle formats and most notably image-based subtitles like VobSub (.sub + .idx) are NOT supported. If you absolutely need to import these subtitles in the MP4 we recommend opening the resulting MP4 with Subler and adding the subtitles from the MKV to the MP4 manually. Subler can import image-based subtitles with an optical character recognition (OCR) engine, which of course is error-prone and only works for english subtitles by default, but it might just work well enough for your movie.

  4. What is the difference between MKV2PS3 and MKV2MP4?

    Basically the difference is that MKV2PS3 can only generate files that contain „AC3“ audio tracks. These files are playable fine on the PS3 and on most other devices and players but only play without sound on some devices (iOS). The benefit of this is easy usage and a very fast and high-quality conversion (most MKVs already have the AC3 audio track, so no conversion is necessary). 
    MKV2MP4 can be configured to produce files with perfect compatibility (which is slower) or to work just like MKV2PS3. It also allows full customization over the audio track conversion.
    If you need files with perfect (standards) compatibility, choose MKV2MP4.
    If you want fast conversion for a device which supports „AC3 in MP4“ (like the PS3), choose MKV2PS3.
    If you are unsure whether your target device supports „AC3 in MP4“, just download the free demo of MKV2PS3 or just settle for MKV2MP4 which can do everything that MKV2PS3 can, and then some.

  5. How can use MKV2MP4 to create videos for the AppleTV?

    MKV2MP4 creates AppleTV compatible MP4 movies by default. The key setting here is to choose „Perfect Compatibility“ in the „Audio Conversion Settings“ in the Preferences, which is selected by default. You should also check the „Convert HE-AAC audio tracks to AAC“ to support some rare movies because the AppleTV only supports HE-AAC v1 but not v2.
    If you also want perfect 5.1 surround sound on you AppleTV, also make sure to check the „Additionally include 5.1 surround audio track“ and „Convert 5.1 DTS tracks to 5.1 AC3“ checkboxes. Note that you need an AC3 compatible 5.1 audio receiver connected to your AppleTV, but this is also true for movies from other sources.
