Question for the scripting wizards…

[Filip Vandueren]

Ok, this is just theoretical, I’m not saying this is the best way, or that render-times will kepp you sane 😉

1. Add the comp or layer to a new comp,
2. Give it two “Linear Wipe” effects
3. The first one needs these settings:
   Transition Completion: expression: 100*((index-1)/height)
   Wipe Angle: 180

Wow- thank you very much.
Never thought about the linear wipe.
Thanks again 😉

Hi,

i created a script that uses masks;

It’s much better, render-times are mcuh better:

just create a comp with 1 layer in it (movie or pre-comp), then run this script:

It asks for 2 values at the beginning: line-height & time-Offset in millisecs, but you should be fine with the defaults (1 pixel, minus 1 frame).

(BTW, if you use a time-offset other than 1 frame, enable frame-blending for a much smoother result.)

[Ruediger Chmielus]

Filip you really,really rule!
WOW!
Thanks a million time;)

Hey Rook,

here’s it’s ‘sister-script’ it does the same thing with vertical masks:

I just dont know what I can say anymore….
you are really flattened me….
….wow….

[Filip Vandueren]

Forget about it 😉

It’s a nice effect and I had thought about it before;
I just need someone else to get me going before I go and find a solution 😎

By The way, I think you get the best effects when you use something like 10 ms, and maybe 2 pixels instead of 1.
As I said with frame-blending enabled (if it’s a video layer, if it’s a pre-comp you need to enable the frameblending there.)
You can use positive or negative values to get a different effect, and the vertical sometimes gives way better results.
Depends on the motion.

I look forward to seeing your final movie if you can upload it somewhere ?

Filip, you can be sure that you will be the first to see;)
I hope that we can shoot the footage in the next weeks. You are right about the frame blending and the pixel width -ah those wonderful possibilities;)
If you need any help with anything I would be happy to support you – I owe you much.
Keep up with your outstandig work.
I will keep you informed about the Project.
