When it comes to setting up a media server using Plex, one of the most important decisions you’ll make is choosing the right video file format for your library. Two of the most popular formats for Plex are MP4 and MKV, but which one is better? In this article, we’ll delve into the world of video file formats and explore the pros and cons of each, helping you make an informed decision for your Plex setup.
Understanding Video File Formats
Before we dive into the specifics of MP4 and MKV, it’s essential to understand the basics of video file formats. A video file format is a container that holds the video and audio streams, along with metadata and other information. The format determines how the video is encoded, decoded, and played back on different devices.
There are two primary components to a video file format: the container and the codec. The container is the file format itself, such as MP4 or MKV, while the codec (short for compressor-decompressor) is the algorithm used to compress and decompress the video and audio streams.
Container Formats
Container formats are responsible for holding the video, audio, and metadata streams together. They provide a structure for the file, allowing different devices and software to read and play back the content. Some popular container formats include:
- MP4 (MPEG-4 Part 14)
- MKV (Matroska Multimedia Container)
- AVI (Audio Video Interleave)
- MOV (QuickTime Movie)
Codec Formats
Codec formats, on the other hand, are responsible for compressing and decompressing the video and audio streams. They use algorithms to reduce the file size, making it easier to store and transmit the content. Some popular codec formats include:
- H.264 (MPEG-4 AVC)
- H.265 (HEVC)
- VP9
- AAC (Advanced Audio Coding)

What is the main difference between MP4 and MKV file formats?
The main difference between MP4 and MKV file formats lies in their structure and capabilities. MP4 is a multimedia container format that can store video, audio, and subtitles in a single file. It is widely supported by most devices and media players, making it a popular choice for streaming and playback. On the other hand, MKV is a more versatile container format that can store multiple video, audio, and subtitle tracks, as well as chapters and metadata.
This versatility makes MKV a popular choice among video enthusiasts and content creators who need to store complex multimedia content. However, this complexity can also make MKV files more difficult to play back on certain devices, especially older ones. In contrast, MP4 files are generally more straightforward and easier to play back, but they may not offer the same level of flexibility and customization as MKV files.
Which format is more compatible with Plex?
Both MP4 and MKV formats are compatible with Plex, but MP4 is generally more widely supported. Plex can transcode MKV files on the fly, but this can put a strain on the server’s resources and may not always result in the best playback experience.
