MKV, CCE and AviSynth Question

[Maikeru-sama]

A poster recently asked me why I convert MKV files to AVI. I thought it was neccesary to convert MKV->AVI->MPEG-2 if you wanted to put the original MKV files onto DVD?

I thought to myself, that is a very good question.

I did some research on the Internet and that is ongoing, but I wanted to ask, is there a way to load an MKV file, even one with H264 into CCE via a AviSynth Script, so I could totally bypass converting to an AVI file?

I tried a couple of things (including the script below) but pretty much got errors in CCE. VdubM said something about "No combination of filters could be found to render the stream"

<SCRIPT>
DirectShowSource("C:\input.mkv", audio=false)
LanczosResize(720,368,0,1,600,336)
AddBorders(0,56,0,56)
ConvertToYUY2()
</SCRIPT>

Is this even possible or must I continue with what I have been doing?

Yes, something like that should work if you have a Directshow MKV splitter like Haali and a Directshow codec installed.

Some codecs used in MKV support variable frame rates. You may need to add frame rate arguemnts to DirectShowSource():

DirectShowSource("file.mkv", fps=23.976, convertfps=true)

The fewer conversions, the better, in terms of encoding time and quality

You should be able to frameserve just about anything with avisynth scripts.

"No combination of filters could be found to render the stream"
=> Check to see if you have haali media splitter properly installed

FYI, convertxtodvd and avidemux natively accept h264 encoded mkv files without scripts and they can be used to make dvds.

Here is a guide for avidemux DVD authoring: http://www.avidemux.org/admForum/viewtopic.php?id=3570

And convertxtodvd is so simple it doesnt even need a guide

EDIT: HAHA I see Jagabo beat me to the punch

FAVC is basically automating what you are trying to do, but uses HCEnc to encode. DVD Flick also does it. The only time I have had issues are a) when the mkv file is full of extra crap - jpgs etc - and a quick demux/remux fixes that, and b) correct channel mapping of AAC 5.1 to AC3 5.1

MKV and Haali Splitter both come with CCCP right?

When I drag the avs script into CCE, I see the splitter stuff come up on the systems tray but still get an error. I also get the same error when I drag it into VDM.

I don't know.

Is there an error message? Can you open the AVS script in a media player?

[guns1inger]

Open the script in virtualdud to see any avs errors

Think DGMPGDec for h264 streams.

forget it, i.e., forget the use of AVISynth DS directly

- VSO ConvertXtoDVD accepts almost all MKV sources

- Almost all-in-one with AVISynth DS that directly renders a MKV will work sometimes, and fail in much other cases

Do you have all needed codecs installed and you can play them in WMP ? fine...then you are able to convert outside VSO bigbrother

but does this simple script :

DirectShowSource("High def source.mkv")

work ?

it's your case, it works 80% of the times. You must use another workaround

it is easy to test, just Google for this keywords :

mkv aac sample rapidshare

you will get a bunch of samples that doesn't work with avisynth's DS directly

any free tool that uses AviSynth's DS directly will fail in that samples over 99%, period...unless....

I have also found that often an mkv that will not open in avisynth will happily open if demux and remuxed without all the associated crap. mkv authors love to dump all sorts of bullsh*t into their files - stills etc. I just extract the audio and video streams, and remerge to a clean file. This usually then processes fine.

yeah...because you are a experienced user, but let them google for this keywords :

mkv aac sample rapidshare

99% of the samples doesn't work with AViSythn's DS, and period

I tested them all, and failed

unless you build your DS Graph filter and input that in AVISynth's DS like this :

DirectShowSource("my_hd_movie.grf")

of course, you must know how to make that DS Graph Filter, it is easy using GraphEdit...but it is hard to do dynamically by a all-in-one soft

TFM was close, but fails also...there is bugs in the DS Graph, bad connection of pins

and more : all-in-one must be able to select only audio and video from multi-tracks mkv containers...period !

that's why I deprecated AVISynth' DS with MKV...this weekend
