Top Video File Formats for Streaming

What are Video File Formats?

Video file formats are unique file formats used to store video data digitally. Every video clip you come across on your mobile, desktop, or TV has a unique format — MP4, WEBM, AVI, MOV, MKV, and more. For instance, the file format of the audio/video content you post on social networking sites differs from that on VOD streaming services.

A video file typically comprises a container consisting of visual and audio data present in the different video and audio coding formats, respectively, and a video codec; that encodes and decodes audio and video files. Once encoded, the compressed data is stored in the container—or file format. Containers also contain subtitles and other metadata— reflected in the file’s extension.

The most commonly used container formats are MP4, WEBM, MOV, and so on. Some widely used codecs are H.264 and H.265 — both highly efficient at preserving video quality after video compression.

Different codecs are paired with varying formats of containers to enhance the compatibility of a video file with different devices and programs.

List of Top Video File Formats

With the sheer number of video file formats out there, choosing the right file format for your videos can be confusing. Here's deep-diving into the top video file formats to give you a deeper understanding of video file formats:


MPEG-4 Part 14, or MP4, is a highly versatile video file format that offers compatibility with various players and devices. Launched in 2001, it is currently the most widely used video file format globally for encoding video. MP4 is highly efficient at compressing video files while retaining high video quality.


MP4 is most commonly used for streaming over the internet. For instance, videos posted on social networking sites like YouTube, Facebook, Twitter, and Instagram.

Pros and Cons

It allows high-level compression without majorly affecting video quality. It is a “lossy” compression format—which means that repeat encoding can lead to loss of information and visible quality deterioration.
You can store text, audio, video, and images and attach metadata to MP4 files, making it compatible with most digital platforms and devices. MP4 files are susceptible to the unlawful distribution of content since you can easily remove the metadata.
MP4 can be used with a wide array of players like Microsoft Windows Media Player, and QuickTime Player, VLC. MP4 files tend to use significant computing power because they contain both audio and video data.


Created by Google, WebM is one of the most efficient video formats for distributing multimedia content to a broad audience base. This open-source video format compresses videos to relatively small sizes, which makes it a popular format for playing videos directly on your web browser. It should be noted, though, that the video quality of the WebM video format is not at par with other high-quality file extensions on this list.


  • The WebM video file type is used for playing videos on HTML5-based live streaming platforms like YouTube and Streamlab.
  • It is primarily used for immediate playback and video sharing on major web browsers like Chrome and Edge.

Pros and Cons

It has higher compression ratio as it is built for the internet. It is not the most suitable format for mobile devices.
It doesn't require significant computational power because of smaller file sizes. It is unlikely to support older players and browsers.
It is ideal for internet-based video services; Best option for live streaming. The high compression ratio of WebM can deteriorate the original video quality.


AVI is among the earliest and most widely supported digital video file formats in existence today, alongside MP4. Developed by Microsoft in 1992, it is compatible with a range of codecs, and video creators/editors can trade off quality with size and vice-versa, should they need to do so.

However, AVI files are still relatively larger in size than MP4, MOV, and WebM, which makes them unsuitable for the web and live streaming.


AVI is supported by every major web browser and operating system like Windows, Mac, or Linux. One of its most common use cases is the TV — which could be the reason behind AVI's decline in recent times.

Pros and Cons

It is mostly used to store large files on computers or share short videos like trailers, advertisements, and more. Uncompressed AVI files can be relatively large. However, compressing beyond a limit can cause a significant deterioration in quality.
Supported by all the major players, OS (Microsoft and non-Microsoft), and internet browsers. It demands greater storage space than other video file formats.
It is known to maintain high-end video and audio fidelity. It is not suitable for live streaming.
It can be used for creating DVDs. It does not preserve video quality after compression and other video formats.


MOV is a digital video file format developed by Apple to support playback on the QuickTime player. The MOV file format consists of multimedia elements such as timecodes, videos and audio, subtitles, and more. It requires high computational power and storage space since it generates very high-quality video.

Barring QuickTime Player and a few other multimedia playback platforms, MOV is incompatible with most players and platforms.

It is supported by a host of codecs and social media platforms, like YouTube and Facebook. File sizes over 4GB on internet-based platforms like Facebook and Instagram are not supported by MOV.
Provides exceptionally high-quality video since compression barely affects video quality. They require more storage space because of larger file sizes.


Launched in 2002, MKV—or the Matroska Multimedia Container—is a free, open-source file format used for storing an unlimited amount of audio and video content, including movies and TV shows. MKV is similar to MP4 in that both file formats can store text, images, subtitles, and other metadata. However, MKV's distinct features give it an additional advantage in terms of support for a greater number of codecs for encoding and decoding and higher video quality.

In addition to this, since MKV is a non-proprietary software, it is considered a universal file format.


  • MKV is most commonly used for streaming HD and online videos.
  • It is used by the VLC Media Player, Windows Media Player, DivX Player, and more.
  • It is an all-in-one video file format that is compatible with almost all video/audio coding formats — even those not supported by mp4.

Pros and Cons

It is a universal, open-source file format. It does not offer widespread support for platforms and devices.
It undergoes regular updates to improve compatibility with novel platforms. The compression technique employed by MKV is relatively complicated.
It can store any number of still images, subtitles, and metadata. MKV's compressed files are comparatively larger, despite the similar quality.


WMV—or Windows Media Video—is a popular video file format developed by Microsoft. It provides high compression, which ensures smaller file sizes—but not without significantly deteriorating video quality.

WMV is supported by Windows Media Player and most other Windows programs but has limited compatibility with other platforms. It works both as a container and codec as opposed to other video file formats. Another advantage is that WMV video files often come protected by video DRM technology.


  • WMV format is best-suited for storing large-sized video content since it doesn't require much storage space.
  • It is supported by Windows-based programs, including earlier version software such as the older PowerPoint.

Pros and Cons

It can store copious amounts of data without requiring considerable storage space. It is not considered a standard, versatile video File format due to its limited support for different platforms.
WMV is quite useful if you need to send a video to someone who uses an older version of Windows. Barring Windows systems, WMV does not offer extensive compatibility with other platforms and devices.
It offers twice as high compression as the MPEG-4 file format. You do not have the option to alter the compression ratio manually.


AVCHD—or Advanced Video Coding High Definition—the file format is used for creating HD recordings for playback on an HDTV. Developed by Panasonic and Sony, it is used by digital camcorders to store DVD and Blu-ray media on hard disk drives and memory cards.

AVCHD is a file-based format that uses the H.264 codec or MPEG-4 codec for the playback of HD video. Compared to MP4, AVCHD video files are harder to move, copy or upload to the internet or other portable devices.
