I'm using glow + blur effects on still images (Titles and credits). I've added 4 keyframes so that the text appears to "blur in" / "blur out".
I'm not sure what the right terminology is, but, I'm looking for a way to improve the "frame rate" or the "rate of change" so that the effect looks less choppy when rendered. Currently if the rate of change for the glow is too fast, then it appears to "jump" between levels of glow. Even if i can just increase the number of jumps, i'd be happy with a tiny bit of choppyness.
