For developers integrating video functionality into applications or streaming platforms choosing the right video format is key to delivering a good user experience. As a developer or content creator, you need a format that balances quality, compatibility, and performance. At FastPix, we help our users make informed decisions for their streaming needs by providing flexible and powerful video solutions.
Think about the videos you stream on Netflix or YouTube. Ever wondered why they play so smoothly and look great on your device? It’s usually because they use MP4. But where does MKV fit in? Let’s dive into the details to help you make an informed choice.

A video format is a type of file format for storing and encoding video data in digital form. It contains a container for video, sound, subtitles, and metadata while the codec is used to compress and decompress the video. The selected format will determine things like file size, video quality, and compatibility with devices.
Codecs are software used to compress and decompress video files. Major ones include:
MP4 is like the universal remote for video formats—it works almost everywhere. Streaming platforms like Netflix and YouTube favor MP4 because it’s compatible with virtually every device and operating system. It’s optimized for fast loading times and minimal buffering, making it perfect for streaming. Imagine it as having a phone charger that fits every device.
MKV: MKV is an open-source format licensed under GNU L-GPL for personal use and available under a BSD license for commercial use. This means you can use it freely without worrying about royalties or DRM restrictions.
MP4: MP4 is not inherently royalty-free; it’s just a format for storing content. The content within them can be, depending on licensing agreements and permissions.
Quality: The quality of both MKV and MP4 is influenced more by the codecs used within the container rather than the container format itself. Therefore, if the same codecs are used in both formats with similar settings, the quality will be comparable. However, MKV files are typically larger because they support additional features such as multiple audio tracks and subtitles, but this doesn’t necessarily mean they offer higher video quality than MP4.
File size: The file size for both MKV and MP4 is influenced by the codecs and bitrate used. MKV files tend to be larger due to the inclusion of extra features, but with advanced codecs, they can be more space-efficient. If you find an MKV file that is smaller in size compared to an MP4 file, it may be due to more efficient codecs being used in the MKV format.
MKV: MKV is supported by a range of video players and editing software like VLC Player, iMovie, and Final Cut Pro. However, it is less universally supported compared to MP4. While MKV can handle multiple subtitles and audio tracks, its compatibility with various platforms is more limited.
MP4: MP4 is compatible with almost every media player, operating system, and device, including Apple, Samsung, Huawei, and Windows devices. This broad compatibility makes it a preferred choice for streaming and sharing.
MKV: MKV supports a wide range of audio and video codecs, including FLAC for lossless audio, which is ideal for high-quality audio content. It also supports advanced codecs like HEVC/H.265 for high-resolution video.
MP4: MP4 supports a narrower range of codecs. It does not support FLAC but offers alternatives like Apple Lossless (ALAC). MP4 can also be encoded with HEVC/H.265, supporting high resolutions such as 4K and 8K.

For developers, selecting the right video format is essential for delivering a seamless and high-quality user experience. MP4 is the format of choice for streaming due to its efficiency and compatibility, while MKV excels in high-quality archiving and flexibility. Understanding these formats and their features will help you make the best decision for your project.
At FastPix, we’re here to let you focus on creating great video experiences for your viewers, while we take care of technical complexities in video with different codecs and formats. With features like multiple input formats, you can upload video content in various formats and codecs, such as H.264, VP8, MP4, AVI, MKV, MOV, etc. This eliminates any need to convert. Therefore, speeding up the video generation workflow and reducing turnaround time. Developer and product builders can integrate video uploads into their applications without worrying about format compatibility. FastPix handles the conversion and processing of different formats, providing a consistent experience across all platforms.
MP4 is generally better for streaming due to its compatibility with streaming protocols and devices.
MP4 is preferred for online streaming because of its optimization for performance and widespread support.
MP4 is widely considered the best format for streaming due to its balance between quality, file size, and compatibility.
MKV supports higher quality with less compression, while MP4 provides good quality with more compression.
MKV offers superior quality and flexibility but is less compatible with streaming services compared to MP4.
MKV: Pros include high quality and flexibility; cons include larger file sizes and limited compatibility. MP4: Pros include broad compatibility and efficient compression; cons include potential quality loss and fewer advanced features.
