Can you open the .avs with Virtualdub, but something is wrong with the
video that virtualdub displays (or doesn't display)? Then it's not a problem of
Avisynth, but of something else.
|
| 1) |
Did you install everything?
I know computers can be frustrating. But I assure
you you won't be able to convince computers to do
what you want, if you don't install SOFTWARE first.
Install avisynth and all other needed programs as I write on the main page. No, the
.avs file won't work if you didn't install Avisynth. Read the manual of Avisynth to see how it can be installed.
Otherwise you will get errors like "Cannot
determine file type".
|
| 2) |
Too stupid to mention, but you have to replace the term "Yourmovie.avi" by the name of your movie. |
| 3) |
Did you forget the quotation marks?
(Yourmovie.avi) must be ("Yourmovie.avi") |
| 4) |
The file has to be in the same folder or an absolute folder
path must be specified
("Yourmovie.avi") fails if there isn't a "Yourmovie.avi" in the same folder as the .avs
If the location of the .avs and .avi files differ use a proper path.
("c:\Yourmovie.avi")
|
| 5a) |
Typo attack? Did you write ("Yourmovie.avs") instead ("Yourmovie.avi")? |
| 5b) |
Typo attack? Did you write ("seperatefields") instead ("separatefields")? |
| 6) |
The videofile itself has to be readable
by Avisynth. That means:
| a) |
Can you play
Yourmovie.avi with the standard
Windows Media Player? No? This is a hint that the
system cannot handle the file. |
b)
|
Did you
install any codec needed to play the
video? If you get an
error saying something like: "Couldn't locate
a
decompressor for fourcc XXXX" that means that the codec, which
is needed to play your video is missing.
The name XXXX tells you what codec is
missing. Every codec has a 4-digit code
(=four character code=fourcc) that
identifies (=abbreviates) it. If the DivX
codec is missing the error would be "Couldn't
locate a decompressor for fourcc divx",
if a DV codec (usually shipped with your
camcorder or capture software) is missing the fourcc
is usually dvsd. Please check fourcc.org
for a list of codec codes.
|
| c) |
If you want to open
a DV .avi (from your
camcorder) you need to have a type-2 DV file.
An error like "Can't find video stream" is
typical in that case. Please use a freeware like DVIO
to record to type-2. There is also freeware flying
around in the internet that converts type-1 to
type-2 |
| d) |
Is the video
file in a special format like
mpeg2 or wmv (in other words: not an .avi)? Then you have to install even
more programs to make it work with avisynth.
For example you have to use mpeg2dec.dll
to be able to read mpeg2 files with AviSynth.
And the .avs file has to be adjusted:
So instead of the normal way for .avi
files
AVISource("c:\Yourmovie.avi")
separatefields
|
You need to do it the special way for
mpeg-2 files:
| 1. |
Demux
(=split audio from video) the mpg2.
This will extract the pure audio
stream into a .mp2 / .mpa
file (=audio file). You need special
software to demux an mpg2 file.
There are freeware programs that can
do that. |
| 2. |
Convert
the audio file to a .wav file (e.g.
with the freeware lame) |
| 3. |
Use this
.avs file to get the file into
Virtualdub
LoadPlugin("c:\mpeg2dec.dll")
video=mpeg2source("c:\Yourmovie.mpg2")
audio=wavsource("c:\Yourmovie.wav")
audiodub(video,audio)
|
|
| 0. |
As a step
before Step 1 you could try to
correct the mpg2 file, if it's
recorded from TV, since pretty all
mpg2 recorded from TV/DVB need to be
corrected. The problem is however
that there is no program on the
market at this time (neither
freeware, nor buyware) that is able
to do it. The only program that can handle nearly all (but still
not all) problems of mpg2 files is ProjectX
(formerly known as ds.jar)

Do not ask me for guides for avisynth,
virtualdub, mpeg2dec, lame, ds.jar and other
software. Please
find the appropriate guides in the internet.
Do not ask me for links. Ask Tigoo.com
(Google). |
