I'm going by this:
http://avisynth.org/mediawiki/Dissolve
In my case I will be dissolving more than 2 clips. So far I had been trying with three and haven't succeeded in getting it right.
My script:
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
Dissolve(a, b, 30)
Dissolve(b, c, 30)
The first video ends up not showing, second video starts instead.
I've tried the "Last" parameter for the first video "A" but somehow the second video plays again.
Better yet, is there a script that will take say segmented video pieces and apply the dissolve at the joined parts? |

If you read your script as
| QUOTE | My script:
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
last=Dissolve(a, b, 30)
last=Dissolve(b, c, 30)
return(last) |
You should see the problem
You're throwing away the first dissolve
(I hate that implicit 'last' and usually use variables instead)
How about
| CODE |
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d=Dissolve(a, b, 30)
e=Dissolve(b, c, 30)
f=Dissolve(d, e, 30)
return(f)

Here is an example with 6 videos:
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d = DirectShowSource("Vid.04.mp4")
e = DirectShowSource("Vid.05.mp4")
f = DirectShowSource("Vid.06.mp4")
g = Dissolve(a, b, 30)
h = Dissolve(b, c, 30)
i = Dissolve(c, d, 30)
j = Dissolve(d, e, 30)
k = Dissolve(e, f, 30)
Return(g + h + i + j + k)
Seems to work but the videos between the first and last repeat twice. Getting close.
though.
Once I get this down all I need are the fade parts on the start and ends which I can use the "fadeio" in avisynth for. |

My mistake. The code I gave should have been
| QUOTE |
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d=Dissolve(a, b, 30)
e=Dissolve(d, c, 30)
return(e) |
Your second one should be
| QUOTE |
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d = DirectShowSource("Vid.04.mp4")
e = DirectShowSource("Vid.05.mp4")
f = DirectShowSource("Vid.06.mp4")
g = Dissolve(a, b, 30)
h = Dissolve(c, d, 30)
i = Dissolve(e, f, 30)
j = Dissolve(g, h, 30)
k = Dissolve(j, i, 30)
Return( k)
|
or (same result, just a different way of writing it)
| QUOTE |
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d = DirectShowSource("Vid.04.mp4")
e = DirectShowSource("Vid.05.mp4")
f = DirectShowSource("Vid.06.mp4")
g = Dissolve(a, b, 30)
h = Dissolve(g, c, 30)
i = Dissolve(h, d, 30)
j = Dissolve(i, e, 30)
k = Dissolve(j, f, 30)
Return(k)
|
This....
| CODE | g = Dissolve(a, b, 30)
h = Dissolve(b, c, 30)
i = Dissolve(c, d, 30)
j = Dissolve(d, e, 30)
k = Dissolve(e, f, 30)
Return(g + h + i + j + k) |
gives you doubled parts because...
g= a + b
h = b + c
put them together and its a+b+b+c
and so on
until you get
return a+b+b+c+c+d+d+e+e+f

Just looking at the wiki page you gave
According to the specs
Dissolve(clip clip1, clip clip2 [,...], int overlap)
You should be able to
| CODE |
a = DirectShowSource("Vid.01.mp4")
b = DirectShowSource("Vid.02.mp4")
c = DirectShowSource("Vid.03.mp4")
d = DirectShowSource("Vid.04.mp4")
e = DirectShowSource("Vid.05.mp4")
f = DirectShowSource("Vid.06.mp4")
g = Dissolve(a, b,c,d,e,f, 30)
Return( g) |
That's normally what the [,...] means "repeat as required"

Thanks! Both of those examples worked. I like the simpler one which was the last one though.
Now all I need to do is use the fade in to black and fade out to black which should be easy.
Before anything else, I will need to convert the MP4 segments to some other format. Loading 72 avc segments and you get an "out of memory" error, guess I don't have enough memory to load that many through avisynth, lol. |
