How do I make a shockwave from video copilots shockwave pack make another layer disappear?

Not sure exactly what you’re trying to do, but this will get you started. Put your shockwave layer above your footage layer. Set your footage layer’s track matte to “Alpha Matte Inverted”. When the shockwave appears, the footage underneath will begin to disappear.

Hi

Thanks for taking the time to reply.

Basically im am trying to get footage of someone’s head to be masked away by the shockwaves revealling just a background behind them. Its like the shockwave is eating away the body and making them disappear.

So at first its just the actors head but then the shockwave starts and consuming the body and making the actor disappear.

I have a clean plate. and dont mind a bit of roto.

You see what I mean?

Thanks.

The clean plate will make things easier. Can you mask or rotoscope the head and use the track matte technique described above?

it seems Im missing a step here or its just 2D limitations. Im going to end up doing some serious mask path keyframes to make this look good. Cheers anyway for pointing me in the right direction
