MKV vs AVCHD: which is better? What are the differences between MKV and AVCHD? This post from MiniTool Video Converter gives you the right answer. In addition, it talks about how to convert MKV to AVCHD or vice versa. Now, let’s see it together.

Videos are stored, shared, viewed, and edited with a program called codecs. Codecs encode data to compress large video files to store and share. Codecs decode the data to decompress video files to view and edit. Video files include two parts: the codecs and the container. The video format is the form of storing digital video data.

There are various digital video formats, like MP4, AVI, WMV, MOV, MKV, F4V, WEBM, and so on.  Every format has its advantages and disadvantages. Most video formats will lose data in compression to reduce the file size.

Here, we are going to make a comparison between the two most common digital video formats-MKV VS AVCHD, including what they are, what differences they have, and how to convert them.

What Is MKV

Launched in December 2002, MKV is a free and open-source container video format. It’s a video file saved in Matroska Multimedia Container developed by Steve Lhomme.

The Matroska involves four kinds of file extensions, they are .mkv for video (also include subtitles or audio), .mk3d for stereoscopic video, .mka only for audio files (may include subtitles), and .mks for subtitles only.

The MKV format supports storing an unlimited number of video, audio, image, or subtitle tracks in a single file. Besides, it allows you to mix and match file formats, such as H.264 video and MP3 audio, or add multiple files of the same type, such as two audio files for multilingual support.

The MKV files are usually used to store short video clips, movies, and TV shows. So, it’s becoming more and more popular in the anime fan subtitles community. MKV is a good choice if you expect to watch your video on a TV or computer by using open-source media players like VLC or Miro.

The Matroska team is aimed at creating a modern, cross-platform, extensible, flexible container format. They also seek to extend Matroska support to applications. Until now, it’s supported by many applications, including, notably, MPlayer, MPV, VLC, Foobar2000, Media Player Classic-HC, BS.player, Google Chrome, Mozilla Firefox, Blender, Kdenlive, Handbrake, MKVToolNix as well as YouTube.

AVCHD, short for Advanced Video Coding High Definition, is a format for the digital recording and playback of high-definition videos, such as recordable DVD media, hard disk drives, and memory cards. It was developed by Sony and Panasonic in 2006.

To compress video, it adopted the MPEG-4 AVC/H.264 format, which supports a lot of standards, high-definition, and stereoscopic (3D) video resolutions. Compared with conventional image compression formats, the MPEG-4 AVC/H.264 format can compress images more efficiently.

To compress audio, it used both Dolby Digital and uncompressed linear PCM audio. The audio data rate can vary from 64 kbit/s to 640 kbit/s.

Moreover, the 3D (MVC format) and 1080/60p(1080/50p) video formats have been added as an extension to make the AVCHD Version 2.0 (AVCHD 3D, AVCHD Progressive) format.

To handle AVCHD Version 2.0-related videos, the device must be compatible with AVCHD Version 2.0.

In addition to this, AVCHD supports not only standard definition (AVCHD-SD) and high definition (AVCHD 1080i) interlaced video, but also 720-line progressive recording mode.

MKV VS AVCHD: What Are their Differences

Next, let’s see the differences between MKV and AVCHD. The details are as follows.

MKV VS AVCHD: Compatibility

In the compatibility respect, you can easily notice the difference between them. The AVCHD format is compatible with the Blu-ray Disc format, xv.Color technology, and several recording media devices. It is mainly used in the video recording field, and some devices don’t support this.

On the contrary, the MKV format is compatible with most mainstream media players and video editing applications like VLC, KMPlayer, Adobe Premiere Pro, and so on. It means videos in MKV format could be played and edited on almost all devices. Thus, MKV wins AVCHD in this aspect.

MKV VS AVCHD: Video/Audio Codecs

MKV is a universal container that can contain virtually any video or audio codec, while AVCHD is a video container widely used in camcorders for high-definition video recording and playback.

About video codecs, MKV uses MPEG-1, MPEG-2, MPEG-4 (A)SP, H.264/MPEG-4 AVC, H.265/HEVC, VC-1/WMV, Real Video, Theora, Microsoft MPEG4 V2, VP8, VP9, and MVC. However, AVCHD uses H.264/MPEG-4 AVC only.

As to audio codecs, MKV has MP3, WMA, Vorbis, Opus, AAC, AC-3, DTS, PCM, LPCM, FLAC, ALAC, MLP/Dolby TrueHD, and DTS-HD codecs, whereas AVCHD uses Dolby AC-3 or uncompressed linear PCM.

MKV VS AVCHD: File Extension

Once the video is stored on your computer, the file extension of the Matroska video is .mkv, while the AVCHD format has three kinds of file extensions: .mts, .m2ts, and .ts.

In video quality and file size respects, there is no obvious difference between the two containers.

After making a comparison between MKV and AVCHD, you should know more information about them. However, MKV VS AVCHD: which is better to choose? There is no right answer. Every video format has its advantages and disadvantages. It depends on the specific occasion.
