MKV Madness

Postby AliceD-25 » Thu Nov 05, 2009 9:23 pm

Hey everyone, I'm new here on this forum. I have been on AnimeMusicVideos.org for some time now, enjoying all kinds of great AMV's, and I finally decided to try to make one of my own. I started out with reading A&E's Technical Guides to All Things Audio and Video, and I downloaded the AMVApp 3.0.

Now the problem I've been having, and a search around the forum showed me that I wasn't the only one, is getting MKV files converted to AVI. I've read about every topic I could find on the subject, read the Various Media Formats Guide. I tried the FFVideoSource en DirectShowSource codes. I tried MKVextractGUI and some other programs, but nothing seems to work. :cry:

The thing that puzzled me was that supposedly I shouldn't have any problems at all if I used the AMVApp. Anyone has some suggestions what the problem might be? I'm completely out of ideas or other methodes to try, so I would be very glad if someone can help me.

Not sure if the amvapp comes with ffmpegsource or not (grab from here, unzip and stick the dll in ...\program files\avisynth2_5\plugins\) but even if it doesn't, directshowsource should've worked.

Please post your avisynth script and any error(s) you see when trying to open it in vdub

the amvapp isn't a silver bullet for editing, just a collection of useful editing stuff.

I realise I'm taking a stick and poking you with it, but with the fact you said you read all the guides, stickies, and you lurked, did you miss the heavy implication that in general your question is connected with illegally obtained source?

There are legitimate uses of MKV but they are rare. Please stipulate clearly this is your situation.

I'm picking on you because I was complaining about this just last night. I won't help someone use MKVs unless they demonstrate their process is one (like storage of ripped BRDs) that follows the Org Code of AMV Ethics. In general this is why your lurking was not fruitful. If you're using MKVs, odds are you are doing something we officially cannot endorse.

@ Kariudo

Thanks for the help, but it didn't work. I downloaded ffmpegsource, and put the .dll file in the plugin directory, but it still gives me an error. So I tried the DirectShowSource command again, and this is what I got.

On a side note, I found a program that converts MKV to AVI with relative quality loss.

@ Kionon

Well yes, I did read that the use of pirated material is forbidden on this site. And I admit, I am guilty. I wanted to use some scenes from the opening of Shigurui, and frankly, I can't afford to buy the whole DVD box for 5 seconds of the material I want to use in the AMV.

Try ffvideosource instead of directshowsource, my 2 cents are on missing directshow codecs.

I've encountered a similar error before. I don't know what caused the problem but it's probably something funny with the mkv file. Try finding a different version of it.

Ziiinnnnn, missed that. I'd try to mux into a ts and load into dgavcindex for the sake of trying something, then. :uhoh:

Windows version of avidemux 2.4.4 gtk?

Avidemux converts MKV files quite nicely. No quality loss, straight to huffyuv.

Well, at the moment I use SUPER to convert the MKV files to AVI which, so far, works fine. :D
The files come out about 100mb bigger, 330mb > 430mb, and I can hardely see any quality loss.
Anyway, thanks for taking the time to help me. :up:

hardly != no quality loss

You really shouldn't edit with anything lossy.

The only hit I got from that error had to do about the filename being malformed, and that it was fixed when the user having the problem changed one character (they of course didn't say anything about what the filename was, or what the character itself was). If you changed the name of the file entirely and went to using the relative path to the file ("test.mkv" instead of "C:\yadda\yadda\yadda\test.mkv"), then maybe it would work. This also goes for the script itself - if the error lies in VirtualDub and not AviSynth, then it would be the script that has a bad filename.

Can you play the script fine in Windows Media Player or Media Player Classic? That should be the very first thing you try, and would reveal whether the error is in AviSynth or VDub (I strongly think it's VDub, as that was the way it was with the other info on the error message that I found).

It might also be of use to update VDub to version 1.9.7, which is the current stable version.

I second getting avidemux. It really is an amazing tool. Even when it says it crashes..... it lies!!

Actually, I do have an idea. If you are tech savvy enough (and want to have fun at the expenses of the ones who will download the files), you can actually hide and split streams of any kind into mkv files, so that if not demuxed properly, the mkv will not be useful for anything else than viewing.
Examples of this are weird hidden video streams that show joke images or whatever else if you try to load the mkv normally.
Overcoming such tricks can be hard to a certain extent, as simply using mkvextract gui to get files out might not suffice...

So your case might just be an encoder having fun at your expenses. :°D
