M4V vs MKV | Which One is Better? 2021

Crystal Chen updated on Oct 14, 2021 to Video Converter Tips

M4V and MKV are two popular video file formats. So, which one to choose? It depends on how you use your video file. Keep in mind that both are container formats. The codec defines the encoding of the video file data, which stores every pixel of every frame, taking a lot of storage.

There are many codecs available but, container formats don't support all of them. So, it is not wise to ask which video format gives better quality. Because the codec, not the container, defines the quality, one can use the same codec for both formats. What distinguishes the two formats are the features, compatibility, and implementation. Let's find out M4V vs MKV, and which one is better, with a guide on how to convert M4V to/from MKV.

M4V vs MKV: Which One is Better?

You might be confused about M4V and MKV formats for your output videos. Keep in mind that a container file selects and combines different codecs into one file. Before deciding what file container to select, there are three aspects to consider: Video Quality, File Size, and Compatibility.

Video Quality: This matters the most if your video is mainly for watching purposes. You would want a lossless file with good colors and precise details. The low-quality streams play videos in low quality. MKV is open source and is more flexible than M4V. Thus, MKV makes your videos digitally lossless, preserving the little details and colors. The lossless the file, the larger the file size. You should choose MKV for good quality videos in larger sizes and M4V for smaller size videos in low quality.

Compatibility: Both formats are limiting. For Apple users, M4V is great. Those who use media players like VLC should use MKV. Moreover, unprotected M4V is more user-friendly than MKV. You can import M4V video to most of the popular video editors like Adobe Premiere. That is why M4V should be your choice if you want to edit the video. For uploading purposes, M4V being small is more user-friendly than MKV. It takes them less time to upload and stream. 

What is the M4V format?

ITunes has M4V as its primary file format. M4V itself is developed from a container for MP4 files. M4V can support Dolby audios (A3C). If you have a protected M4V file, you can open it with a licensed version of Apple products. Or you can authorize the device on which you are using Apple iTunes.

For unprotected files, any program that accepts MP4 can open M4V. Moreover, many codecs are officially registered for M4V. The most widely supported ones are H.264 and H.265. You can download other codecs and add them to the software you are using for M4V files.

What is the MKV format?

MKV is a container media format that is free and open source. It is supported by a vast number of platforms. It can contain many data streams in a single file. Moreover, an MKV file can have multiple media streams in one file. This means that you can encode a movie in an MKV file to contain dual language audio tracks in a single file.

One MKV file can save individual files separately. You can store multimedia files in an MKV file and play them. Also, it becomes easier to organize a lot of data. Many tools support MKV format on Mac and Windows.
