Walking Through Walls

[Andrew Kramer]

Is your shot locked off (on a tripod)? Is it just a ghost fade, or somehow magical.

If the shot is locked off you could probably dumplicate the part of the wall tha he enters, and overlay it over where he goes through.
Just feather the edges of the wall where he would intercept. You can also use masks to follow and round the edges of the intercepting parts like his hands and body.

Good luck.

Yes probably locked off. Not sure about how you envision the duplicated section of wall. Some of how the effect happens will depend on the camera angle to the wall and how wide the shot is – don’t know that yet.
I’m guessing that if you pasted a section of bkg over the forgnd, that the scale would be off (i.e. he/she would be bigger than they should be at the point they pass through the wall) because they physically have to be some distance from the wall in the shooting process.

There is the green screen and matting/roto route but I was looking for a way where I didn’t need to do that for each time the effect happens.

Thanks for your input.

Basically what I was suggesting is you have a wall on the right and a person on the left walking to the wall for example. Make a freeze frame of the shot where the right wall is not obscured. Then overlay that over the footage with a linear wipe and a feather that cuts off just about where he intercects the wall and then his plate should seem to disappear underneath the piece of wall.

It’s not ILM but it should get you started.

Does this make sense?

Yes, I will test that I just think that it might seem as if he is at the wrong scale.

Thanks.
