As a professional broadcaster or live streamer, you must understand the technology that makes or breaks your content. Choosing the appropriate video streaming format is part of that learning curve. A hotly debated topic in the world of streaming is the choice between two video formats: MKV vs. MP4.
Streamers often need help deciding which format works best with their brand. Unfortunately, there isn’t a clear-cut answer. Each video format has pros and cons, so a deeper analysis is required to make an informed decision.
Both the MKV and MP4 video formats are used for streaming content. The newer of the two, MKV, offers better quality than its older counterpart. However, compatible devices, or media players, are more limited for MKV compared to MP4. Most devices support MP4 without any problem because of its backward compatibility. The format you choose depends on your preference and what works best in your situation.
We’ve done a detailed MKV vs. MP4 analysis to help you decide. Keep reading to understand the main differences, areas where each video format shines, and where they fall short. By the end of this article, you’ll be able to answer the question, “Which is better, MKV or MP4?”
MKV: A Quick Overview
MKV is short for Matroska Video, which Steve Lhomme developed in 2002. Today Lhomme works as a Google developer, while MKV is the most common video streaming format.
MKV is a free, open-source container format that allows various audio and video tracks, as well as subtitle files, to be packed into a single file. The name Matroska is derived from the Russian Matryoshka dolls, which come in decreasing sizes and can be placed inside one another.
With an MKV file, you can watch a video that features audio in multiple languages with their respective subtitles. This helpful feature allows for smoother sharing and distribution of such files.
MP4: A Quick Overview
The Moving Picture Expert Group introduced MP4 in 1998, making it their standard video format. Of all the container formats available today, MP4 is one of the most widely used file formats due to its many benefits. It can be used with most devices, such as phones, laptops, computers, and tablets, without any buffering or lagging issues.
While MP4 is a digital container file, MPEG-4 is the standard format for encoding the video content stored within MP4 files. Although several MPEGs are available, the MPEG-4 Type 12 is the standard output format for all your video files. Aside from storing video and audio multimedia, MP4 can also contain subtitles and images.
MP4 supports various audio and video codecs similar to MKV format, including H.264, H.265, and AAC. MP4 is also compatible with the two powerful streaming protocols, Apple’s HLS and MPEG-DASH.
MKV vs. MP4
Now that you know the basics of MKV and MP4 let’s review the major differences between the two formats. Learning the aspects in which they differ will help you understand which format suits you best.
1. Quality
Video and audio quality also differ when it comes to MKV vs. MP4. Although MKV files are typically larger as they pack multiple data files, it does not provide higher video quality than MP4. That’s because the video quality is influenced by the codecs used in the container rather than the container format itself.
Since MP4 and MKV are output formats instead of encoding formats, the final video quality will depend on the video and audio codecs you pack. If the same codecs are encapsulated using the same settings in both MKV and MP4, the quality will be similar.
2. Supported Platforms
MKV format supports a wide range of video and audio tracks, HD quality movies, and movies with numerous subtitles tracks. Other than that, mainstream video editing software like iMovie and Final Cut Pro are compatible with MKV, as are video players like VLC Player and Blu-Ray. Unfortunately, the number of MKV-supported platforms is limited compared to the MP4 output format. Considering the large number of platforms on the internet, MKV is only supported by a select group of video and audio players.
MP4, on the other hand, is compatible with almost every media player, operating system, browser, and operating device, such as Apple, Samsung, Huawei, Windows devices, and more.
3. Compatible Audio and Video Codecs
MKV can store a wide range of supported multimedia content, including video, audio, subtitle tracks, still images, and more. The list of MKV-supported audio-visual encoding formats is extensive, making it ideal for streaming TV shows and movies.
On the contrary, MP4 has a comparatively narrow range of supported audio and video codecs. Another area where MP4 falls behind is that it doesn’t support FLAC. MKV does, which allows for better audio. FLAC is short for Free Lossless Audio Codec, one of the top audio coding formats that allow for lossless digital audio compression.
That doesn’t mean MP4 doesn’t have alternatives for lossless compression. It supports Apple Lossless and ALAC, though it is far less efficient than FLAC. MKV and MP4 can be encoded with the HEVC/H.265 video codec, which supports UHD resolutions such as 4K 2160p and 8K 8320p.
Pros and Cons of MKV and MP4
Understanding the difference between MKV and MP4 isn’t enough to know which of the two container formats would work best in your situation. Both have advantages and disadvantages. Where one video format lacks, the other can shine. So let’s look at the pros and cons of each.
Pros of MKV
- Open Source: The key advantage of using MKV is that MKV container files have no licensing requirements. This helps developers optimize their files and provides better compatibility with the latest systems.
- Active Developer Community: While many might overlook this benefit, it makes using MKV extremely convenient. The highly active developer community helps you navigate the world of MKV while ensuring the format adapts to changes.
- Adaption: MKV file format has enough compatible platforms, devices, and OSes. When compatibility with another platform is required, it usually does not take long before an update is released to tackle and eliminate any errors.
- Support: The range of supported menus is extensive, including those found in DVDs and Blu-Rays. In addition, the audio tracks and subtitles can be assigned in multiple languages, which you can manage independently for each video file. That means users don’t have to keep the subtitles activated at all times.
- Quality: MKV files usually offer higher video and audio as they’re packed with certain additional features. Many prefer MKV over MP4 when projecting the display on a bigger screen to get a higher video resolution.
Cons of MKV
- Audio Quality: While MKV offers high-resolution video, the audio quality is usually compromised when recorded using a low bit rate with subpar equipment. You may also encounter issues with decoders and even experience several pauses in files when the volume goes above a certain level.
- Compatibility: Since the MKV file does not offer compatibility for all devices, it may require frequent updates if it fails on any device.
- Structure: At times, you may need to acquire specific components for playing MKV files, as their structure is independent of most platforms.
Pros of MP4
- Support: As the latest audio and video codec, MP4 files have all the necessary support and compatibility for various devices and platforms.
- Compression: MP4 files are known for improved compression of files compared to their predecessors. This type of compression produces smaller files without compromising the quality of the content.
- Streaming: One of the main advantages is streaming video to MP4, for which MKV files are generally not preferred. Hence, an MP4 container file is the best option for playing videos over the internet. Not just that, you can even use YouTube live stream to MP4 for a smoother experience.
- Compatible: MP4 files are also compatible with preceding format types. That means devices that don’t support MP4 but do support their predecessors will experience no trouble in playing the video encoded in the stated output format.
Cons of MP4
- Compression loss: The compression of MP4 files results in a loss of information in the original file.
- Copyright: MP4 files are copyrighted. However, they are sometimes distributed illegally by removing the metadata.
- Codecs: MP4 files do not support all codecs, so users must acquire them from a third party.
