  • matching layer with 3d perspective

    Posted by Pablo Gonzal on September 9, 2008 at 9:21 pm

    Hi!, just a simple trouble… hope so…

    I have a live-action footage showing the stage of a theater from the stage perspective. The stage has two parts, one lower than the other. The footage has no movement, the only thing i need to do is moving up the lower level, to match the upper level. I’ve been trying to do it just by ‘eyeballing it”. I duplicated the layer, mask the lower level, activated the 3d box in the layer, and tried to make the effect just by make keyframes and combining position and x rotation. But i just painful.. i just dont get it…

    If I’m seeing things correctly and understanding your issue, it looks like all you need to do is to mask off the bottom and move it upwards. the edges will get cut off but that can be fixed with things like brush cloning, motion tile or duplication and offsetting.

    Hi Roland, i’ve been trying to shift up the layer with a mask, the problem i’m having is that the movement doesnt match the perspective of the frame, and when i try to softly rotate the layer as is goes up, its just doesnt look real. Thxns! any ideas??

    Take the still into Photoshop. Push the balcony up a row, clone the corners, and the repeat. Save it as a still. Then track your footage. Combine the two elements, by attaching your still to the tracked footage, since your comp is extra tall you can add in a pan down if you need too. Last step, match the grain of the film footage to make sure it doesn’t look too static. Hope that helps.

    Sorry Pablo, I just can’t visualize the precise issues you’re having. If it’s an angle/perspective problem then perhaps a pinch of corner-pinning may help.

    Good Luck
