MPEG2toVirtualDub

[BaronVlad]

Hi,

My aim was to capture from DVB and then store to DivX / XVid. Therefor I have to get the MPEG2 Stream finally loaded into VDub(Mod). I know there are many ways to do this, please look here if you want to know more. But why should we all do nearly the same again and again manually ?

Jory Stone (jcsston) wrote a frontend for VirtualDub, that does this job for you.

To quote him:

1. This is what it does Select a set of MPEG-2 files, or separate MPEG-2 video and audio files

Optional: Demux the TS stream with cPVAS

2. Create a d2v project with DVD2AVI commandline
3. Decode the mpa to wav with MADPlay, use DirectShow Decoder, or use the MPASource AviSynth plugin
4. Write a AviSynth script
5. Cropping and various resizing methods
6. FieldDeinterlace, Decomb IVTC, DeinterlaceMAP and/or noise reduction with FluxSmooth
7. Open the script in VirtualDub

IMO it is the easiest way to get a high quality DivX / XVid from your digital caps.

You can get the newest versions from his site at Tripod or Geocities

If you need help with this nearly self explaining program there is also a howto on this page.

The procedure is nearly the same as described in my little guide (german link), that we will hopefully see in the near future on doom9.org in English language.

History of Jorys program is here in the VDub support board.

Although I made many movies without any problems please report probs and bugs here.

Thats all

Thanks again Jory for this great program that made capturing so easy

i didnt find it made it any simpler.

Hi cofferscuffs,

you should just try it, then you will see. No need to use different programs and to do it step by step, just make your settings, then go and drink a beer or milk (whatever you like ) come back and start encoding. For me it is that easy and comfortable, much more than the "hard way"

[cofferscuffs]

i did use it. and "the hard way" isnt that hard after all.... i just found this to be more hassle after i got used to my way of doing it

[BaronVlad]

Since this was exactly my way, it is good to have a proggie that does it for me now...

It is the same as it is always. The "freaks" do it manually, but imagine you were a noob with now clue how avisynth works, what to do with pvastrumento and you dont want to read any guides. Think it is easier then ? Believe me: I am very very lazy and I use it because of that laziness...

...I bet you also use this software but you cant admit it now...

[cofferscuffs]

now, i actually do hate pvastro, ds.jar is much better for demuxing (btw have you noticed pvastro getting less accurate with new versions for damaged gops - meaning that it drops more then it should?)

although i have changed my method quite a bit now;

1) demux source with ds.jar
2) split the video in m2edit and save the timecodes of the split points in a txt file
3) make a dvd2avi project file out of the split video
4) encode to format of choice
5) split source audio with the saved timecodes in besplit
6) encode split audio to format of choice in besweet
7) mux

Hello,

maybe you could use a directshow-decoder (like the latest mpgdec.ax in the moonlight-player from www.elecard.com).

Use it with avisynth2.53`s DirectShowSource() to open your mpeg2 files:

[test.avs]
DirectShowSource("yourmpeg.mpg")

with several sources:

[test2.avs]
a=DirectShowSource("yourmpeg.mpg")
b=DirectShowSource("yourmpeg2.mpg")
c=DirectShowSource("yourmpeg3.mpg")
return a+b+c

then open test(2).avs in vdub(mod), this should be the easiest way...

just to report a minor bug:

when your filename contains any of "[" or "]" it won't work.
Just rename your source files

BTW BaronVlad your bookmark is not working
doom9.de seems to be dead
just put "212.63.136.4" instead of "doom9.de"

[ch@@boom]

just some notes:

1)
i don't know what it causes but when you have chosen your mpeg2 file and try to use fieldDeinterlace
it produces a script with parameters like "wahr", "falsch" and so on.

VirtualDub pops with an error; i guess it cannot handle german

you have to replace it manually with "true" and "false", then it works

2)
the program kills itself when i try to minimize it in the task area

3)
this prog is really great but i have some problems :
i have a direct .mp2 file from my dbox2 over the network.
i use the Mpeg2VirtualDub to feed VirtualDub and encode to DivX.
as it is interlaced i have to deinterlace it (MapDeinterlace).

so far so good, but when i view an encoded test clip on the pc i see blocks when there is a scene with (slight) moving

is this caused by DivX or deInterlace ?

using winXpPro SP1, PIII-800Mhz

Thanks ch@@boom, link corrected
