MKV to MP4/M4V: Convert Video from MKV(Matroska Video) to MP4/M4V(MPEG-4 Video) with River Past Video Cleaner, MKV2MP4/M4V converter, conversion


What is MKV?

Matroska aims to become THE standard of multimedia container formats. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers.

It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is completely open source. Matroska file types are .MKV for video (and audio) and .MKA for audio-only files.

To convert MKV files to other video formats, please have CCCP installed.


What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

To encode MP4 video, you will need River Past MPEG-4 Booster Pack in addition to your video software. Do not forget to have the latest QuickTime installed.


Additional Requirements 

To convert from MKV(Matroska Video) to MP4/M4V(MPEG-4 Video) video with River Past Video Cleaner, you must have River Past MPEG-4 Booster Pack installed.

Change the "Audio language priorities" and "Subtitle language priorities". For example, use "eng" for English or "jap" for Japanese.

Select the file you want to convert and click "Open". The file will be added to the conversion file list.

If you cannot add the file, please make sure CCCP is installed. You may also need other codecs depending on the video and audio compression used to encode the MKV file.

Select output format

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Output Format" label to expand the panel. Select "MP4 - MPEG-4" as the "File Type".


Troubleshoot

If you have MPEG-4 Booster Pack installed, but don't see M4V as an output option, you have a problem with QuickTime installation.

Please make sure you have the latest QuickTime installed. Occasionally, QuickTime may be corrupted due to conflict with some other software. In any case, reinstalling QuickTime should fix this problem.

Note: To convert to MP4 (MPEG-4) video files, you must have Apple QuickTime installed.

Note: The MPEG-4 Booster Pack must be installed for the "MP4" output option to show.

Change Video Settings

Click on the toggle to the left of the "Video Settings" label to expand the panel.


Select "Specify" under "Size" and/or "Frame rate" to enter the video resolution and/or frame rate.


You can change the compressor, quality, size, and frame rate of the video.

The bitrate is in the unit of kbit/second. Use this formula to calculate the video size per minute:

Video size/minute (KByte/second) = bitrate / 8 * 60.

Change Audio Settings

Click on the toggle to the left of the "Audio Settings" label to expand the panel.


Select the audio compressor for the conversion. Depending on the compressor, you may also change the sample rate, channel (stereo or mono), bits/sample, and bitrate.


Select output directory

Expand the "Output Directory" panel. Use the "Browse" button to select an output directory.



Convert

Click the "Convert" button on the tool bar.
