Magic Music Visuals

Hi,
I have 3 questions. I use MMV for fx on simple music videos of me playing an instrument and/or singing.

1) Is there a gaussian blur? I saw a radio and noise blur under 2D Fx, but not a gaussian one?

2) Is there a way to "mix" the inputs into the main output? The main out being the box that says MAGIC at the end.
So..... I can route a input video directly to the main out.
I can route the same input video to some fx block, and then to the main out.
How can I mix, or set the opacity of the 2, or more, inputs into the main out?
Can I change the mix over time?

3) If I want to use an fx block, but just at a certain time or place in the video. For example if I have a 3 minute music video and I want a glitch fx at say 22 seconds, 1:12 seconds and then at 2:43 seconds..... how to do that? Is there some example project that shows how to do this? I know you can make global variables; but how would you watch the timeline of the video and compare it, or test it to see if it has reached a certain time and then turn on the glitch fx?

Thanks
AJ

There is a Gaussian blur. In ISF->Blur. Perhaps you haven't downloaded the resource pack?
Yes you can mix with the mix or multi mix node. The two (or more) sources go into the mix node then from the mix node to the output (Magic) node. There are many ways to time the mix, you'll have to be more specific.
