MKV stands for 'Matroska Video'. Matroska is a container file format, capable of holding unlimited number of video, audio and subtitile tracks, along with any metadata. Practically this means that it is possible to put entire movie with multiple sound and subtitle tracks, chapters information and movie thumbnail into single file. Being open and patent-free Matroska gained broad support recently and quickly becomes de-facto standard for storing movies. More information can be found at Wikipedia article.Why MKV
Matroska file format (and Matroska video in particular) has a number of advantages.- MKV is open and free. No one holds patents or licenses and anyone can implement it freely. As a result nearly every software player and many hardware devices support it. The best software players out there ( VLC, MPlayer ) have full MKV support and are absolutely free.
- MKV files do not have evil features attached.
- You can play them on any capable hardware. No need for HDCP-certified video card or any 'trusted' environment.
- You can copy them to your laptop and watch anytime, even if your laptop lacks DVD or Blu-ray drive, or any drive whatsoever.
- One file is one title. If you don't want to watch dozen trailers before the movie, you don't have to. And fast forward button always works, too.
- There are no restrictions where to play the file. There are no region-based restrictions. You have control over the content you've paid for.
- MKV files are easy to change. Want to remove unneeded audio track from the file? Thought about converting MPEG-2 video into H264 to make the file 5 times smaller? All of it can be easily done with free software.
- MKV files are compact. For exactly the same content MKV files are about 10% smaller than DVD files and roughly 40% smaller than Blu-ray files.
While MKV is a good storage format not always it can be played directly. Playing MKV files on a computer is not an issue - there are many players and codec packs that enable MKV playback on any platform, be it Windows, Mac or Linux. However many hardware players do not play MKV directly - for that MKV files need to be transcoded into format that particular hardware player understands. Since all meta information is preserved in MKV and compressed media data (video, audio, subtitles) is not changed in any way it is always possible to transcode MKV files into original format. For example, MKV files produced from a Blu-ray disc may be transcoded back to a Bly-ray image or set of M2TS files without any losses by freeware transcoding tools[1].
Playing MKV files
Freeware players that support MKV natively:
- Videolan VLC is a free and very good player for Windows, Mac and Linux that supports MKV directly.
- MPlayer is another free player with MKV support.
- CCCP is a free codec pack for Windows that will enable MKV playback in Windows Media Player and all other DirectShow-based players.
Transcoding tools:
- tsMuxeR is a free tool that can transcode MKV file produced from DVD or Blu-ray back into Blu-ray disc or M2TS file[1].
note
- Please note that commercial blu-ray discs are proteced by technologial measures preventing unauthorized duplication (including, but not limited to, 'Cinavia' technology). MakeMKV doesn't remove such measures, so MKV file produced from a commercial blu-ray disc will not play on a blu-ray player, even when converted back to M2TS format.
MKV is the shortened version of Matroska Video. It gathers multiple types of files, including subtitles files, audio tracks, multiple video tracks, etc. to one file. That is to say, MKV video is usually in much larger file size. And due to its large file size, we may meet some troubles when uploading MKV to certain vidoe sharing sites, and plan to store more MKV movies on our storage device. Sometimes, we even find the screen resolution of our devices do not support the playback of large resolution file size of MKV. So is there any free ways to compress big MKV file to smaller size? Yes, of course there is. Just follow the tutorial below to compress big MKV files with no quality loss.
Part 1: Parameters that affect MKV file size
Before compress big MKV file, we need to learn these video parameters that affect video file size, which will help us make sense of the options we have while compressing MKV.
Codec: This is a method that computer uses to decide on the amount of change that occurs between frames.
Keyframe: This is a reference frame. The codec will determine a keyframe every few frames. This is the base frame for the next few frames of change. Your keyframe interval will have a large impact on the size of your MKV file. Lots of keyframes will make the file large but higher quality. Infrequent keyframes will leave lots of artifacts.
Artifacts: These are blocky pieces of image that are the result of the keyframe not being updated correctly. The lower the quality of the compression, the more artifacts that will appear.
Bit/data rate: This is the amount of data that each second of video uses. Typically, this is measured in kilobits per second. Bit rates can be either Constant or Variable. A constant bit rate stays the same throughout the video, which can lead to larger video files. A variable bit rate changes depending on the amount of action on the screen, which will lead to smaller files.
Frame rate: this is the number of frames per second. Videos are typically shot in 24 or 30 frames per second. Keep the compressed copy's frame rate the same otherwise playback will be affected and audio may not sync properly.
Resolution: This is the size of the outputted video. It is measured in pixels, width x height.
Part 2: How to Compress MKV Files on Mac/Windows?
After comprehending these video parameters that affect MKV file size, let's start compress big MKV file to smaller one. As I know, there are mainly two methods to compress MKV video file size:
Method one: Compress MKV by converting MKV to H.264 MP4With same video quality, MKV file size is much larger than H.264 MP4. To shrink MKV without quality loss, we can convert MKV to H.264 MP4.
Method two: Shrink MKV by adjusting MKV video bit rate, resolution, frame rate, etc.This method helps to shrink MKV files to achieve a good balance between quality and file size.
To successfully compress big MKV, you can choose method one to change video format, or use the second method to shrink MKV file size. You can also utilize the two methods at the same time to compress video file size.
Then, here comes the question: how to convert MKV to MP4 and how to adjust MKV parameters? Here I highly recommend iMedia Converter for Mac, which is a easy-to-use video converter and compressor for Mac users (support macOS 10.13, macOS Sierra, Mac OS X 10.11 El Capitan, etc). It is capable of converting and compressing 4K/ UHD/1080p large video file like H.265, MKV, XAVC S, MXF, MTS, M2TS, AVCHD, etc. to small file size in the file format of MP4 with H.264 codec. Futhermore, this MKV compressor also provides video editing functions for you to reduce video file size, such as cut out unwanted segments, lower the file resolution or bit rate of the output video, etc.Apart from compressing common video file, this program also gives you a chance to compress Blu-ray or DVD to your desired file format or device preset profile formats. Here is an equivalent version for Windows: Pavtube Video Converter Ultimate.
