is alike [pix_biquad] (but faster) and [pix_blur] (but more flexible). You can give 2 arguments: the number of feedback-taps and the number of feedforward-taps (in this order). No yuv-optimization is made (because of genericity). A test: [pix_blur] takes (on my machine) between 16% and 26% (mean: ~20%) [pix_tIIR 1 0] takes approx. 24% to 28%.
cool. i will have to take a look at this and see about writing yuv and altivec code for it. i have some FIR code as well. can you post some specifics of your testing like cpu/ram/movie file and frame rate so we can compare performance?
CPU: p3-1.2GHz RAM: 256MB-DDR movie: anim-1.mov fps: 20
