interlace/aliasing unwanted effects
Well, i’m dyin’ here, and need a life because i’m posting on christmas eve, but here goes:
all i’m trying to do is rotate a still image (pict file) about the Y axis (left to right rotate, not top to bottom) over a moving background, and at the 90 null point, rotate another pict back around on the other side. simple move. done it a hundred tmes in my accom affinity. i have a beveled border around them and they are squeezed down to about 80% of normal size. i have about 2 dozen of them to do.
i’m getting TERRIBLE interlacing artifacts on the edges of the picture. i have put the de-interlace filter on them, and the flicker filter. i’m using the “basic 3d” filter to effect the y-axis rotate. i’ve tried the anti-aliasing filter, but all it seems to do is soften the pict file. i attempted to add a motion blur filter, but the render time seemed unreasonable.
the motion/edges seems ok in the canvas window, but the output on the ntsc monitor (thru the firewire out to the dsr-1500 tape deck, and then out to the monitor) looks like CRAP!
i’m using FCP 3.0.2 on a single proc. G4 450, with os X.3.9.ANY help you can give me would be appreciated.

Ok, you’re using DV, that’s a crappy format for effects, especially when you start rotating stuff. The only way to get clean edges is to apply some crop, as little as .25 will suffice, then feather the edges a little. That will give you edges that are not aliased.
FCP 5 does a MUCH better job with effects and edges, especially using the High Quality video processing settings.
