Part 3: MKV VS AVI
What is MKV?
MKVis a multimedia container format that supports unlimited video, audio, image, and subtitle tracks (such as .SRT, .SSA, .USF) into a single file. MKV has certain features that set it apart from the other previous file formats. Firstly, MKV can contain virtually all kinds of video and audio codecs. Secondly, it also supports multiple streams of video, audio, subtitles, or chapters, making it the most flexible format now.
The greatest advantage of MKV is that it supports many advanced codes such as H.265/HEVC and H.264/AVC, which are not even supported by AVI. H.264/H.265 are the two most popular formats for HD and 4K content, making MKV the preferred format for HD videos and Blu-ray rips. However, this also means that MKV files are often large in size.
What is AVI?
AVI is the container file format used by the majority of PC media players, mobile devices, and millions of online video sharing sites. It has become the most popular file type for sharing high-quality videos on the Internet. Thus, sometimes we do need to convert MKV to AVI. AVI files support a range of video and codecs, and many AVI files shared today are DivX files (comparing with MKV video, AVI has relatively fixed video/audio codecs).
AVI describes the manner in which the streams of audio and video are broken down into huge part of data and still organized in a strict timeline. This allows AVI to be read linearly during playback, which would not be possible if streams were written in their entirety one after the other. This makes a critical difference for optical storage solutions like CD, DVD, and Blu-ray, where seeking back and forth can be extremely slow.
Why do You Need to Convert MKV to AVI?
1. Convert MKV to AVI for mainstream media players
One of the main advantages of converting MKV to AVI files is the fact that AVI can be played by more different players. If you store or distribute your own movie through an AVI file, it could be seen in Real Player, VLC Media Player, Windows Media Player and QuickTime.
2. Convert MKV to AVI to keep excellent video quality
Early AVI files were limited on choice of video and audio codecs, quality, and resolution. Even the AVI file size is restricted to less than 2GB. However, with the introduction of DirectShow, AVI became a very flexible and powerful architecture. Some newer codecs including DivX and XviD enable AVI files to have similar or even better quality than DVD.
After converting MKV to AVI, the output quality is still favorable. Besides, thanks to some masterful MKV to AVI converter software like HD Video Converter Deluxe, you can save AVI videos in standard resolution, 480p, 720p, even 1080p HD without quality loss.
3. Convert MKV to AVI for easier playback
If you have some unfriendly video files like MKV, AVCHD, M2TS, BDAV video, you have to find a collection of the most common decoding drivers (usually called codec packs). As to play back MKV video, if you do not worry to install other MKV players, then you need install CCCP to make MKV video playable on your Windows Media Player.
Sure, the way has its benefits, but it really wastes resources to download and install MKV codecs that are in reality never needed. Besides, it is simply the fact that every Windows user knows - the more software you install to your computer, the more unstable and "wobbly" it becomes (this is the point why MKV to AVI conversion still leads the trends even MKV video is somehow more advanced).
