matroska-logoIn this guide I will describe you the steps on how to easily convert MKV video files to  AVI. Of course someone would ask why to do this, MKV along with the H.264 codec has better quality. Well a simple answer is in order to reproduce the video file on a standalone divx player and watch it in your TV or in any other portable device that doesn't support mkv files. Just for the record MKV stands for Matroska Multimedia Container and it is an open standard free container format, in other words it's a file format that can hold video, audio and subtitles in a single file.

First of all we have to check what is the video codec of our MKV file. To do so open the video with VLC (download VLC). Go to Tools > Codec Information and check the video codec. Now there are two cases:



Case avc1:

If the video codec is avc1 it means that our video is encoded with H.264 and therefore we must convert it to DivX. Download and install Xvid4PSP, a freeware software which allows many video types convertions.

Load your video file and choose the following:

Format > AVI Hardware or AVI Hardware HD
Video encoding > Xvid HQ Ultra
Audio encoding > MP3 CBR 128k

Press E next to Video encoding

Encoding Mode > Constant quality if you want a fast convertion or 3-pass quality if you want a good quality/size ratio

If you choose the 3-pass quality and you want the best quality set the Quantizer to 1. If you want a smaller video file set it to 2.5 - 3.0



Finaly press the Encode button. Depending on the original video size, your options and your computer it might need a lot of time for the convertion to be accomplished..



Case XVID, DX50, DIVX or 3ivx:

If the video codec is XVID, DX50, DIVX or 3ivx it means that the MKV files is encoded with Divx and therefore we will just have to demux the video and audio from the mkv file and then put them in an AVI container.

First download MKVTollnix and install it. Next download MKV extractGUI and unzip it in the same directory with MKVToolnix. The default location of MKVToolnix is C:\Program Files\MKVtoolnix . Run MKVextractGUI2.exe

Now open the mkv file and check the video and audio tracks and press Extract.



Two files will be created a .avi (video) and a .mp3 or .aac (audio).

Next download AviMux (the binary file is the one you want), run it and open the .avi file and the .mp3 or .aac file. Press generate data from source files and finally press Start.



This case is much faster than the previous one sinve no convertion is needed. In a couple of minutes you will have your avi file ready to be played in any standalone DVD player!

Barack, which case have you followed? Did you follow all the steps as mentioned above?

avc1 is the first case Tidus. Just read it from the start.

I get an error from xvid4psp when trying to convert
0
vlc reports
Stream 0:
Codec: H264 - MPEG-4 AVC (part 10) (avc1).
Stream 1:
Codec: DTS Audio

VLC can play it without problems.
But when I ask XviD4PSP 5.0 to convert it, I can see the ffd is launched, then it says audio demuxing, but then I get an error, it says that ffmpegsource: can't create decompressor: Unsupported compression method.
Then what?

I Love your post, and also love http://www.winxdvd.com/resourc...to-mkv.htm(rip Blu-ray movie to MKV), and http://www.winxdvd.com/resourc...to-mkv.htm(Convert M2TS to MKV), because the MKV is so flexible that has quickly become the preferred file extension for high definition video on the Internet.

How about subtitles?
0
Hi axel,

I just have a question.

I want to convert my MKV file to an AVI but it has some subtitles on it because this file is an English subbed video. So I was wondering if the subtitles will remain there once it has been converted into an AVI?

Some advice would be appreciated. Thank you.

Hi Bendee,

In mkv files the subtitles aren't hardcoded in the video. They are different streams. Therefore they won't remain when you convert it into an avi file.

Hi again axel,

I tried converting those MKV files(which are 'fan subbed' episodes btw) that I was talking about before and it actually worked. The subtitles remain there. I may need to do more testing though just to see if they stay there once I have burned them as AVI files into my DVD disc.

I have another question. Is there any way that I can make the conversion process a bit faster? I am using the first case solution and it usually takes me 1 hour and 20 mins per file. Any suggestions? smilies/cry.gif

Thanks.

What I just said in the title: Thank you for this. You, sir, are a gentleman and a scholar and all that.

I'm an all-around self-thaught geek and I'm usually good by myself, but I was going mad with this. I went through about a dozen programs and three times as many discs and I couldn't figure the whole thing out. I guess it pays to ask to the people who actually know every now and then.

What about languages?
0
Hi, I was just wondering if there is any way to include the different languages I have here in this file also in the conversion. I have used example 1. The file has demuxed audio files for each language. I just kept the one that I needed but since it is an extra file....
Any suggestions?
And thanks a lot for the good explanations, I was totally helpless so far.

Best AVI quality conversion for DLNA/HDTV purposes
0
Well, actually there's another reason to convert mkv files to avi: DLNA. I have a Sony BDP-270 and it isn't capable to receive wirelessly in any other format from my Windows PC. It's a mix of Sony & DLNA limitations.

I have my video files in mkv containers (mostly h264 video) and I don't want to reduce the quality (have an excelent HDTV connected to the bd above). I need to know if is it possible to make this convertion keeping the original video quality.

Thank you a lot in advance! Excelent guide...

DLNA get Samsung
0
My Samsung HDTV [6 series] streams mkv over the DLNA connection. It isn't wireless, but my router is already in my entertainment center. Just a note if someone is looking for a tv.

Thanks for the guide, hoping this will work on my Coby V-ZON.

Any way to define file size ?
0
Hi,

This is a fantastic method and I am trying it while I am typing this. My appreciation goes to you for posting this guide and also your efforts. I used to use Megui and I have a question. I am trying to convert an MKV to AVI to be viewed on my DVD player. Hope it works! My question is, is there a way we can define the size of the output in xvid4psp similar to Megui or do we have to rely on the software ? If there is not, is there an alternative to keep the size to 700mb or near about ?
Any help will be greatly appreciated. Thanks in advance

Hi,
Sorry I forgot to add....defining a size without losing much quality...

Thank you

Hi ace_ventura2. Play with the video encoding settings such as the Quantizer or the Profile to see if you can get your desired file size.

Only to make something clear:
Mkv is not better quality than Avi. Only uses little space in comparison, but quality of video is the same.
Last Xvid codec, used in avi videos, can work with 1080p.
Example:
1 mkv(h264) video 1080p 2gb = 1 avi(xvid) 1080p 3.5gb

Dont believe it?
Try it before any kind of complains.
