What are the advantages of converting a mask path to a Shape layer path?
A related question...I have shot a clean plate BG, then talent walks into shot with a big card in hand. What I'm having to do is shrink the card in his hand. Pretty simple I've duplicated the layer with the card in hand masked out the card on one layer select Add for the mask on the other select Subtract so when I scale down the card the clean BG covers the scene.
After scalling down the card the perspective is a little off so how can I move the mask points to change the perspective of the card in the scene because if I move then in their current state they just eat into the masked image.
Is it possible to do this?
Right-click on footage --> Track motion. No masks required at all, just a conventional 4 corner pin. Feel free to use mochaAE or explore all sorts of otehr workflows using combinations of tracking and masks.
Turn the layer into a 3D layer and rotate it into position or, and this is usually much easier, add Effect>Distort>Corner Pin.
