How to Do MKV-to-MP4 Conversion
In this article, you will learn everything you need about MKV-to-MP4 conversion, the formats themselves, and solutions to commonplace problems related to MKV files.
Cannot open a video or audio file on your device?
Most likely, your TV, tablet, or smartphone does not support the format of the input file. Try to update your device firmware or just convert the file.
Is your video choppy or jerky?
The input file is probably too heavy for your device. But you can make it smaller without any visible loss of quality. No sound? Just change an audio codec using an MKV-to-MP4 converter.
Not enough storage for a new movie?
You can easily reduce the file size from 8 GB to 2 GB and have four times more movies on your smartphone or flash drive. You won’t see any difference.
MKV (Matroska Video) is a free container format that lets you combine multiple audio, video, and subtitle streams – which is why it became so popular for movie storage. One file can keep audio tracks in all languages and many subtitle streams that can be switched on the fly. However, MKV files can have different properties, and the fact that your TV or smartphone is able to play one MKV file doesn’t mean that there won’t be any issues with another. Therefore, many users prefer converting movies to a single format (usually MP4) that will definitely be opened by their devices.
Currently, MP4 is the most popular container format for storing media content: video, audio, subtitles, and even images (for example, images of movie intros). Even though there is an MPEG-4 video codec, files with an MP4 extension can contain videos encoded by other codecs – for example, H.264 or H.265. Due to a good ratio of quality and size, this format has gained immense popularity and is supported by the largest number of devices and platforms, including iOS and Android.
There are different ways to do this conversion – we’ll discuss some of these in detail below.
