dissolve-filter + AviSynth1.0beta5

Wilbert · 17th January 2002, 17:10

A couple of days ago I installed the new version of AviSynth 1.0 beta 5, I've never used AviSynth before. I wanted to use this to fade in/fade out my videoclips. The fade out filter exists and works perfect. There doesn't exist a fade in filter but one could use the dissolve and blackness filters for this. The blackness filter works fine only the dissolve doesn't work. When I try:

Dissolve(AVISource("f:\file1.avi"),AVISource("f:\file2.avi"),10)

to make an avs-file, it only returns the first avi file when opening in TMPGEnc or VirtualDub. Am I doing something wrong, is it a bug ???

Same problem for me

I think it's a bug

But you can use FadeIn in combination with Reverse.

Trim the part you want to fade out. Reverse it. Do fade in. Reverse again.

This should work...

Yes, the Dissolve problem is a bug, but there is an easy fix for it. I can dig it up if anyone cares, but I posted it somewhere else.

You can grab a fixed binary at http://web.mit.edu/rjr/www/avisynth.dll if you want. It also fixes a problem with the BicubicResize, although the arguments are reordered to put the optional floats at the end. Also, it has broken IPC support, since the source code available seems to be missing the IPC source and includes a broken object file.

You might want to read this thread. While the methods discussed therein do not use dissolve, I find them to be an effective means of fading video clips in and out...
