Part 2. 4 Desktop MKV-to-MP4 Converters to Convert MKV to MP4

Desktop converters are generally suitable for large video files, batch processing, and offline use. They also tend to offer more control over encoding settings.

1. HandBrake

HandBrake is a software program that can be used to convert videos from one format to another. The program can be downloaded freely. It can encode videos from various sources such as DVDs and MKV videos into MP4 formats. It gives various encoding settings to allow users to customize their preferences.

Conversion of the MKV video file is done by opening HandBrake, selecting the video to be imported, choosing the MP4 container and finally proceeding with encoding using a preset of your choice.

Limitations: HandBrake generally re-encodes video instead of simply changing the container. This can take time and may affect quality depending on the settings. Its many options can also be confusing for beginners.

2. Aiseesoft Video Converter Ultimate

Aiseesoft Video Converter Ultimate is a desktop media conversion program designed for users who prefer a graphical interface. It allows you to work with popular video formats and has an easy process to convert MKV files to MP4 with fast speed. The software can be very helpful if you have to convert several video files at once. Aiseesoft can preserve the original quality, like 4K, 1080p, 720p, etc.

All you have to do is import the MKV file, set the MP4 format from the list of formats, change the settings if required, specify the location, and begin the conversion process.

Limitations: Some features may require a paid license.

3. VLC Media Player

The VLC Media Player is an open-source video player that comes equipped with the ability to convert media files. Using the VLC video player for conversion will save you the trouble of having to install yet another application when you already use it for viewing videos.

In VLC, select the conversion interface from the menu, load your video file, select a compatible profile with MP4 format, give the file name for your converted file, and click on the convert button. Ensure that you have selected the correct profile.

Limitations: Conversion process in VLC is less user-friendly compared to that of a converter software. The available settings could also need tweaking, while some codecs or subtitles might not migrate as expected.

4. FFmpeg

FFmpeg is a free, open-source multimedia tool that supports various containers and codecs. It is especially effective in cases where you have many files to convert or process automatically.

If your MKV file has codecs compatible with those of the MP4 format, then the conversion can be done without re-encoding. This command will help:

ffmpeg -i input.mkv -c copy output.mp4

The software does not encode but only duplicates the audio and video streams. The method is very fast, and there will be no quality reduction if the streams are compatible with the MP4 format.

Limitations: The software operates through a command-line interface and hence may prove difficult for novice users. The stream compatibility should be checked; otherwise, re-encoding of streams might become necessary in case of non-compatible codecs.
