AVISynth and "Reverse"

[Tolwyn]

I've read the documentation, but it assumes that I know what I'm doing or can understand it.

I'm trying to "reverse" an AVI clip.

My AVS is so far:

a = AVISource("c:\temp\foo.avi")
Reverse (a)


What am I doing wrong?

Hi-

How about:

AVISource("c:\temp\foo.avi")
Reverse ()

?

[celtic_druid]

or:
a = AVISource("c:\temp\foo.avi")
Reverse (a)
return a

In the original example, there is no video to output.

You have to remove the space between Reverse and (a), thus

a = AVISource("c:\temp\foo.avi")
Reverse(a)

or just

AVISource("c:\temp\foo.avi")
Reverse

celtic, celtic ... the video is not reversed in your script

[celtic_druid]

Ok, so
a = reverse(a)
return a

This single line script works:

AviSource("source.avi").Reverse()

Or this:

Reverse(AviSource("source.avi"))

In the absense of an explicit Return() AVISynth defaults to returning the result of the last operation.

very good forum.
I posted earlier [2 movies in 1 sceen] and got good leads.
I got the Reverse to work and at last figured out the Stackhorizontal command.
I was trying to create a new movie, let say #3, made of 2 movies (#1 and #2) playing in same screen next to eachother.

here is my script for who ever might be interested (and like me doesn't know much about this world):

Stackhorizontal(AVISource("C:\movie1.avi"), AVISource("C:\movie2.avi"))

works great. thanks to all of you.

I always did it this way:

a=AVISource("c:\temp\foo.avi") 
a=Reverse(a)
return a

or like this

a=AVISource("c:\temp\foo.avi") 
return Reverse(a)

Or this way:

AVISource("c:\temp\foo.avi") 
Reverse()

Unless you need more than one video, labels aren't required. Here's an example of the need for labels:

a=AVISource("c:\temp\foo.avi") 
b=Reverse(a) 
stackvertical(a,b)

[Wilbert]

AVISource("c:\temp\foo.avi")
stackvertical(last,last.reverse)

[SLK001]

Okay, maybe not!
