Pedro,
Well, I like Fotomagico for this as well, but the Noise Industries plug is nice too. But, no one here told you about optimizing your stills for this kind of thing. 300×300 images are going to blur or pixelate at a broadcast size. You may need to upscale them with PhotoZoom Pro, which does a great job. As a rule, photos for animating in FCP should be twice your frame size at 72 dpi. FCP chokes on hi rez files.
Have a wonderful day.
