shadow on key footage and 3D layer
help help please, i have a video footage of a girl with alpha channel, I have to add a reflection
…well a little bit hard to explain for me in english , whatch this site http://www.boulaburton.com
the reflection stay close to the dog even if feet are not on the same line, with 3D layers it would be like duplicate the layer and reverse it …the result is that feet dont match in space if they are not on the same line. How to do that please help -

That footage was probably shot on a green floor with a clear perspex laid over it. The perspex provides the reflection, and the green is then keyed out.

thanks, but this is not a solution, the solution in the tutorial is easy and you can do that in different ways, but it works only if all the part of footage lay at the bottom on the same plane. I upload a still of the video at this address https://www.no1.it/cafi/reflex.jpg as you can se the foot behind does not match. In http://www.boulaburton.com they did it,
so….any solution? I’ve used IL real shadows but it only allow to project a color shadow …..not a reflection on a white floor.

yes, this could be. It was probably shoothed with the reflection in it. At the moment It would be ok for me if I find a way to put the reflection/shadow that always match with the actor even if dosen’t get in distance when the feet of the actor is not on the floor. Someone know how to have an effect like IL real shadows that proiect the footage instead a solid color shadow ?
Thanks -
hey mister la ronde,more focused and less assumptive next time. thx

It looks to me as though you are assuming the floor plane to be horizontal.
Draw an imaginary line between the feet in each layer. These lines need to be matched up. Rotate and position your reflection layer (in 3d space) to match the imaginary lines up. This’ll put your reflection layer at about 30 degrees (give or take) to its current position.
You’ll probably have to keyframe both rotation and postion. If there’s a lot of motion involved, you might even need to motion track.

[WOWfactorX] “This’ll put your reflection layer at about 30 degrees (give or take) to its current position.”
Actually, it’ll probably be more like 60 degrees, once you get the perspective right.
