1. MKV vs MP4

As one of the most mainstream video formats, MKV has its strength and weakness in comparison to MP4, AVI, MOV, and among others. Here, I want to take MKV vs MP4 as example to show you the differences from 6 aspects.

(1) Format: Both MKV and MP4 are a container format rather than a media format. They are used to integrate videos, audios, pictures and subtitle tracks into one single file. But MKV supports more files formats than MP4. Almost all formats of videos, audios, pictures and subtitle tracks can be merged to one single MKV file. While for MP4, it only supports specific formats like H.264 and MPEG-4. This is the biggest difference of MKV vs MP4.
(2) Compatibility: MP4 has a stronger compatibility than MKV. You can enjoy MP4 files on almost all devices like iPad, iPhone, and Android, but MKV encoding is not supported by all decorders. So if you want to watch MKV movies, you need to find a special MKV player Mac or Windows.
(3) Size: MP4 is usually smaller than MKV, so there is low bandwidth consumption for MP4 video.
(4) Quality: MKV files are higher than MP4 files in video quality up to 1440x1080/30p (16:9). So if you want to watch HD videos on your laptop, choose MKV as the output format. That's why people are willing to convert Blu-ray to MKV.
(5) Recoverability: MP4 is hard to recover once there is something wrong with your computer, while MKV files are easily recoverable after crash.
(6) Purpose: The generation of MKV is to take the place of AVI, while the coming of MP4 is the upgradation of MPG.

Now, you must be clear about the pros and cons of MKV format compared with MP4. And there is a belief that you are likely to convert MKV to MP4 in order to play MKV files easily on various devices for MP4 format’s strong compatibility. So methods of converting MKV to MP4 are to be introduced.
