Hi, this tutorial is partly a feature request/plugin request, yet I have a fully working .CAPX that is probably more complicated than it should be.
Exactly like cartoons interpolate cross-faded frames in between key-frames, this method can make a stuttery low-frame animation last long and animate smoothly while using low video memory.
Check out the included .CAPX and let me know what you think and any ideas you have to make this method easier to achieve.
