AviSynth has no GUI (graphic user interface) that comes with it, so you have to make these scripts in a program like Notepad.
when you save the file, save it as filename.avs (the .avs at the end tells other programs that you want to use AviSynth to do something)
AviSynth scripts can get quite complicated, but all you will put into this script is the following.
- Code: Select all
the parentheses at the end are very important
to address your next concern, you're probably using footage encoded with divx or xvid.
these are bad codecs to use to edit footage (but great codecs for distribution).
You'll probably want to re-encode the footage with a lossless codec such as Lagarith
(get the latest codec and installer, not the source code). You don't want to re-encode entire episodes, just small clips. This can be done in VirtualDub or VirtualDubMod (personal preference, vdubmod is better imo)
there is also a guide on the site that can help you with AviSynth and VirtualDubMod (if you aren't/haven't reading/read it already)
and then go on to the next page too.
if you're serious about making high-quality amvs, you should read the whole guide
