Hi

I am quite inexperienced with after effects and created a project using a template.  I have gone in to make a few changes and it seems that the fast blur effect is now obsolete.  Can someone tell me how I can fix this in this template?  Any help greatly appreciated.

    Correct answer David Arbor

    It was actually replaced with the Fast Box Blur, which is the GPU-accelerated version of the now obsolete effect. Gaussian Blur is the Premiere version with different math, so if you're looking for the classic Ae-style Fast Blur but faster, go Fast Box Blur.

    There is also directional blur which does the same thing

    Each of the blurs has slightly different math, and will have a different look than the old Fast Blur, especially at large values.  I found that the old Fast Blur is still accessible, though hidden, if you want to use it.  If you convert an older AE project that already has Fast Blur in it, it will still work in AE 2020, with the name "Fast Blur (Legacy)."  From there, you can create an effect preset to apply it more easily.  I'd recommend getting accustomed to using Fast Box Blur.

    Replace with the new Gaussian Blur. It is GPU accelerated and now it has the edge treatment option.
