Most people think that the production of a video is all that matters and after that all they should do is to export the video and share it. But this “sharing” is exactly where they should dig in more. Because as your purpose for video making changes, the file you’ll share your video through it should change. Video files are varied in size and quality so to determine the best video file format for your video, you must consider three elements, the purpose of the video, the desired quality and size limit. 

A video file consists of two parts, the “codec” and the “container”. The name of a video format is usually the name of the container only, so let’s start with knowing what that is.

Video containers

As the name represents, a container is where every element of a video is collected. Elements like video, audio, subtitle, codec, etc. Each container is in tune with a specific codec(s) to create a special video format. So you need to know them to find the best one for your need. Some of the common containers are as below;

MP4

MP4, which is the short form of MPEG-4, is developed by Motion Pictures Expert Group. It’s considered as one of the most popular video formats for online and offline use as the size it produces is rather small but the quality is high. It’s also compatible with a list of players and is matched with H.264 and H.265(HEVC) codec.

FLV

FLV, is encoded by Adobe Flash software and is more useful for online video viewing but it’s also supported in some offline players. Because of its small size which made it easy to load while keeping relatively good quality it was popular once, but it’s not so common these days.

MOV

MOV, is developed by Apple for its Quicktime player. Its quality is very good but at the cost of a large file size. Although it’s designed for Mac OS, you can use the windows version of Quicktime to play MOVs on your computer or use some third-party players.

AVI

AVI, is one of the oldest video formats which is produced by Microsoft for Windows OS. It is a widely accepted format as it works with a number of codecs and it can be played on many video players. But the file size is usually large which makes AVI a better option for offline use.

WMV

WMV, somehow a specialized format for emailing videos as its size is the smallest possible. But an intense lack of quality in this format is the drawback which makes it suitable only for preview videos. The main player that supports this format is Windows Media Player that exists on all versions of Windows OS.

Video Codecs

Video codec implies the process of compression and decompression of a video in which some your data might be lost. If the compression deletes some of your data, then it’s a lossy compression and the result would be a smaller file size but also lower quality. But if the compression keeps all the data in, then it’s a lossless compression that results in a high quality video with a large size. Below are the codecs you need to know about;

H.264

This one works out pretty good for most projects. It’s specialized for HD and higher quality videos and is well-matched with MP4. so it can be played on many players and also a perfect option for video streaming. Needless to say that it produces small size and high quality as it goes with MP4. In fact H.264 does lower the quality but minimally and that has made it an ideal codec.

HEVC

It’s developed by JCT-VC and is also called H.265. Its focus is on 4K and Blu-ray videos and is famous for high efficient compression that reduces the size to almost half of what it is while maintaining the quality. It’s mainly used by GoPro cameras. But keep in mind that HEVC is very resource-heavy and it needs a high spec device in general.

DivX

Another codec with high-quality video in mind that produces large files is developed alongside its open source version XviD. the common case for this codec is for lengthy videos and cases with no size limit.

MPEG-4

It’s a very useful codec because of its high compatibility and perfect matching for online video streaming. It also has features for 3D rendering using VRML(Virtual Reality Modeling Language) which makes it even more practical.

MPEG-2

This is the compression standard mostly used for DVD and Blu-ray but can also work for the digital cable and satellite industry. The quality it produces is rather normal but it’s somehow lossy. So you shouldn’t expect it the highest rate possible. However, It would be much better if you do the compression in 6Mbps range but the file size will increase.

What File Format for What Video Platform?

In general, choosing the right format for your video is completely depending on the way you’re going to use or distribute it. But a very common combination especially for platforms like Youtube is MP4 and H.264 that also works on many platforms and players. If you want a hierarchal list of the formats you can check this table by ESA/Hubble that includes all the formats.

Video Players
