Cookie Cutter (Sony Vegas)

[xFredo]

Well, I'm a bit new to the AMV making business. I've seen several AMVs where people used the cookie cutter fx to cut out a bar of the clip and make that bar the same clip but in black in white. Now my question is how do they make the effect last for like 1 second? (just for when the beat hits so it can go with the music) When I try to do it, it stays there for the rest of the video. Then I tried to make a key frame right after it to make it go away but then it fades away (becomes smaller till it goes away) I just want to make it go away instantly so I can make another right away to go with the music. Can anyone help me?

So... as far as I got it... you want to change the cookie cutter instantly to the beat? Well... The simple way is to cut the clip with ever beat into parts of your original clip and apply the cookie cutter style you want to every bit.

Is this the solution you were looking for?

This is the least comprehensive answer ever but as a quick fix, if you're having a problem with something fading out instead of cutting off, just put the next clip on the layer above it on the timeline. If the next clip is the same one and you just don't want it to fade, put the same clip on two tracks and apply the effect to the one underneath. Cover up the fading out footage with the clip without the effect.
You will probably need to learn more about keyframing and masking but this might help you at the moment if I understand the problem...
Always remember to think in layers!
