I was watching some After Effects video tutorials on videocopilot.net, and I think it would be incredibly useful if the Blender compositor had a node that worked the same way as AE’s wiggle expression.
For those who don’t know, the wiggle expression basically allows you to add camera shake to a shot as a post-pro effect. What it does is translate your layer a certain number of pixels that you set in a random direction. The direction changes however many times per second you specify.
So a node would need magnitude and rate controls at a minimum, and a separate set of rotation controls. (Rotation magnitude would be in degrees of course, rotational wiggle should still have its own rate control.) The final element needed would be a scaling value so that you don’t end up seeing beyond the edges of your composition.
Perhaps this might be better as a VSE effect, I don’t know. I think the VSE and compositing system should be merged together somehow anyway… At any rate, I’d appreciate your thoughts.
