Topic: What's the Best Codec for Video Enjoying, Editing and Uploading
If you are video enthusiasts, whether you've ever wanted to enjoy downloaded movies on your media player or render the footages in iMovie for showing your masterpiece on YouTube later on, you'll possibly be aware that codecs possess the black art in dominating the video performance. But things only get more confusing when you turn to in-depth study of the various codecs, not to mention the best video codec that will work for you. If you are the one wanting to know what's the best lossless video codec, the following tips will cover most for you.

Basics of Video Codecs

A video codec is a device or software that enables to encode and decode digital video. To put it another way, the codec is capable of compressing the originally huge video file into smaller one without degrading too much quality and then decompressing it for full-quality playback. Below is the list of the best-known video codecs.


Codecs

Note


MPEG (Moving Pictures Expert Group):

There are 3 different types of MPEG-MPEG 1 (mpg), MPEG 2 (m2v) and MPEG 4 (mp4). MPEG is a codec as well as a container.


MPEG-1:

Old, supported by everything (at least up to 352x240), reasonably efficient. Good format for the web.


MPEG-2:

A version of MPEG-1, with better compression. 720x480. Used in HDTV, DVD, and SVCD.


MPEG-4:

A family of codecs, some of which are open, others Microsoft proprietary.


H.264:

Most commonly used codecs for videos uploaded to the web. Part of the MPEG-4 codec.


MJPEG (Motion JPEG):

A codec consisting of a stream of JPEG images. Common in video from digital cameras, and a reasonable format for editing videos, but it doesn't compress well, so it's not good for web distribution.


DV (Digital Video):

Usually used for video grabbed via firewire off a video camera. Fixed at 720x480 @ 29.97FPS, or 720x576 @ 25 FPS. Not very highly compressed.


WMV (Windows Media Video):

A collection of Microsoft proprietary video codecs. Since version 7, it has used a special version of MPEG4.


RM (Real Media):

A closed codec developed by Real Networks for streaming video and audio.


DivX:

In early versions, essentially an ASF (incomplete early MPEG-4) codec inside an AVI container; DivX 4 and later are a more full MPEG-4 codec...no resolution limit. Hard to find mac and windows players.


Xvid:

Closely related to DivX but less widely used.


Quicktime 6:

Apple's implementation of an MPEG4 codec.


WMV9:

A proprietary, non-MPEG4 codec from Microsoft.


Dirac:

A very new open format under development by the BBC. multimedia


Three Principal Goals for the Best Video Codec

To be frank, knowing the common video codecs is just in the infancy of manipulating video performance. For an ideal result, having a clear idea of the best video codec in mind is the kingly way.

Originally, the video codec regarded as the best usually gets a knack for producing video that closely approximates the fidelity of the original source while delivering the smallest file-size possible in the meantime. But with more and more people being big on cruising the web, speed of compression and decompression shall be also taken into consideration when ranking the best video codec. The typical examples are shown in posting a file to YouTube and streaming a live event.

Which Is the Best Video Codecs for High Quality, iOS, Android and Web

Now that you know speed, quality of final image and size of the compressed file are the paramount importance in judging the best video compression codec, the following four parts will show you the best lossless video codecs respectively for high quality, iOS, Android and web.

1. Best Video Codec for High Definition

MKV: It shall be mentioned that MKV is rather a container than a codec, which is the most popular container for high definition content. It simply stores the bytes from a codec in such a way that MKV-compatible applications know where to find the video, audio and subtitle data (if pres
