Animating Lens Blur
Hi there,
I’ve just come back to an age old problem…. Namely animating the Lens Blur effect. However you do it; animating the depth matte, animating the aperture size, 8-bit, 32-bit…. whatever….. it seems to increase the blur in discreet and obvious jumps. In other words it’s not smooth.
Does anyone know of any workaround for this or is the only solution an expensive one? i.e. Frischluft Lenscare?
Thanks,
Ben.

I’ve tried most things. At higher blur values, the blur moves in discreet steps… it will hold the same frame for four or five frames and then change. And this regardless of whether you use keyframes, linear, eased, continuous or use a smoothly changing depth matte layer in 8, 16 or 32 bit.
For instance, animating the Blur Focal Distance without using a depth matte in 16 bit, the property’s value on frames 2,3,4,5 are 20580, 20797, 21015, 21232 respectively – a uniform change of 218 per frame. Yet frames 2,3,4 are identical and 5 is suddenly different.
I think there’s something kooky with the maths inside the plug-in.
