By "smoothly changing", you mean, perhaps, "crossfading" (non-instantaneously)? Check out jit.xfade (and Jitter Tutorial 8).

Hi,

I have some abstractions that might help: http://www.hellbender.org/ikehmope.php

Look at ike.xfade_auto, ike.xfade_auto_dualstate, ike.toggle_xfade and ike.mix_xfade. I haven't touched these in a few years, but they should work fine with current versions of Max/Jitter.

links at the page you pointed are not working.

Try it now...

I connected more than 3 different input to router, only one video comes out from message command 'patch'. the router output doesn't xfade with anyother matrix. how can I make self video easing itself? delay? alphablend? gl command would be better.

try jit.slide perhaps? does a kind of blurring over a specified duration. not really an xfade, but can accomplish similar results with only one stream.
