MKV2M4V

MKV2M4V

       Mac OS

This app can convert MKV files to M4V (MP4) 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's video track. Also it can decode the FLAC audio codec. And if you have a SRT file, it is available to insert a closed caption.


Features

MKV, FLV files can be converted to M4V or MP4. (Sandbox*)
• Also, you can use MKV2M4V as a simple media info app. And if the source video track's codec is supported in the m4v (mp4) container, you can convert it.
• Following formats also can be dragged into the main window to open: mp4, m4v, mov, avi, ts, tp, trp, wmv, rmvb, mts, m2ts.
- If you drag the folder that includes 'BDMV', it will automatically search 'm2ts' files in 'BDMV'.

• If the source video track is not H.264 codec, it may be not converted normally.
• The copied video track may be not supported on the OS-based media playback App or Devices according to the H.264 settings of the source video track.
- For example, the video track with an 'yuv420p10le' (yuv420p 10-bit) pixel format is not supported on the OS-based media playback App or Devices.
• The video track with a wrong timestamp may be not compatible with 'FFmpeg' and 'OS-based media playback feature'. In this case, it requires the re-encoding of the video track. You can do this by other apps.

* There are some restrictions as the followings by 'Sandbox', if files are NOT in the following folders and its subfolders: ~/Downloads, ~/Movies, MKV2M4V's place to save.
- If you open 'files' (not 'folder') when 'Same as Source file' was checked, it can't write a file to the folder that includes these files.
