This is a pure Flame newbie question, but how would one go about compositing a shadow on a subject in a 60 frame animation, I dont want to paint it on, I want to create a black spline/mask and overlay it, change the opacity as desired and animate it.
1. I have the clean plate, just the background.
2. The finished composited subject over the background.
3. And a solid black frame. If needed?
How would I do this?
In After Effects, I would simply overlay a black solid layer over the plate I want to draw the shadow on, then I would create a mask so the outside dissapears, then i lower the opacity, feather it, animate it, and walla I got an animated shadow over my composite.
How can I convert this workflow over to Flame 2007? Thanks!
Not sure about the Flame, but in the Smoke, its not that hard.
First you have to look at the shadows in the Background element. Where is the light source coming from that would create the shadows.
If you have undefined blurry shadows, you can just use a matte and create a nice round blurry shadow and adjust the transparency to match the scene.
Another way to do it, is to draw a mask around the subject that is casting the shadow. Use a new layer and make it black. Adjust the rotation of the layer so that it matches the angle of the BG.
Again, not sure how you do this in Flame.
