With a single-line script, you can add support for segmented capture files,
AVI files of more than 2 gigabytes, QuickTime MOV files, or MPEG files to
applications which don't support them natively. With Trim, Splice, and Dissolve,
you can select and rearrange scenes from raw video footage. With ReduceBy2,
BilinearResize, and BicubicResize you can resize video frames (with a quality
similar to Photoshop and better than Premiere). With SeparateFields and
Weave you can edit interlaced video on field boundaries. With Pulldown you
can remove 3:2 pulldown. With SpatialSoften and TemporalSoften you can de-noise
your video for much-improved quality in output formats like MPEG.
Installation of Avisynth
The installation of AVIsynth is easy. First make sure that there is no old
version of Avisynth present on your system. (you can check this by searching
for avisynth.dll on your hard drive). Secondly, you have to download AVISynth
from the download page. Inside the zip- file, avisynth.dll is present. Copy
this file to the \SYSTEM directory of Windows 9x (\SYSTEM32 for WinNT/W2000).
When this is done, run the install.reg file which is also included in the
zip-file. The installation is done by double clicking on this file. A popup
window should tell you that it is installed. Now Avisynth is registered
and working. With the installation of AVIsynth, the encoders are able to
read the *.avs files.
Tested operating systems:
I have personally tested it on Windows 98, NT and 2000. So this should be
Ben Rudiak-Gould started with AVIsynth. It was a very nice tool but it had
some bugs. The most annoying to me was the audio misalignment bug (v0.3).
Because it irritated me so much, I started programming and solved the bug.
Back then, Ben was still active and helped me with enhancing AVIsynth. While
releasing that new version, Ben made a new version too (v1.0beta3). Unfortunately
this version had no IPC module in it. Ben asked me to put my IPC code in
the new AVIsynth program, so I did and sent him the code. But then Ben disappeared
(October 2000). He has never responded to my e-mail again. Because of this,
I decided to release this version myself. At that time I noticed that Ben
was asking a financial contribution for his work. Since then, I never heard
anything of him. From that time I tryed to solve the bugs that were present
in AVIsynth v1.0beta3.
The Premiere plugin is totally rewritten and has changed a lot since then.
I hope I can find the time and energy to further enhance avisynth and the
There is one known bug in AVIsynth that forces you to disable the DirectShow
filters in TMPGEnc. If you still run into problems, please read the FAQ
on my web site. If you discover new BUGs, please post them in the project
on the sourceforge server.
- TMPGEnc behaves strangely when using the AVS scripts (e.g. is
Disable the DirectShow filters in TMPGEnc when using AVIsynth. You can
find out on my site how to do this.
- Encoder/player will not read the AVIsynth scriptfile ?
I noticed that many "new" programs do NOT use the Windows functions
to read the AVI files. If they do NOT use those standard Windows functions
AVIsynth will not work. Known programs that do NOT use those routines
are CCE 2.62 SP and Windows Media Encoder Vx.x. Furthermore, I heard
that there are problems with Windows Media Player 7.
