video alpha with videoplane

Hello,

I’d like to fade between two videos that have been scaled (using videoplane and jit.gl.render)

I tried to use jit.scalebias (jit.qt.movie >> jit.scalebias to change the alpha value >> jit.gl.videoplane), but the result was a fade between one of the videos and the background.

I’m sure there is a simple solution…

Anybody can help?

Thanks

But it’s not much more complicated to do this sort of thing with jit.gl.slab, which will certainly give you better frame rates with bigger videos:

Hello,
and thanks very much for the reply.

I’m trying to learn more about slab object right now.

I couldn’t open the linked patch. It looks like “1006.3oc0Zt0aZCCEG etc…” in my browser.
Is there another way to receive it?

- select everything from the first dash to the last
- copy to clipboard
- paste into empty max patch
- read documentation someday
