MKV2M4V

MKV2M4V

       Mac OS

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.
• Following formats also can be dragged into the main window to open: mp4, m4v, mov, avi, ts, tp, trp, wmv, rmvb, mts, m2ts.
- If it drags the folder that includes 'BDMV', it will automatically search 'm2ts' files in 'BDMV'.

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 video player 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 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.
• If the video track has a wrong timestamp, it will attempt to repair it.
• Although repair it, the converted file’s video track can still have a wrong timestamp. In this case, it may be not compatible with 'OS-based media playback feature' and it requires the re-encoding of the video track. It can do this by other apps.
