    Luma Corrector, HLS and Unsharp Mask video effects dramatically slow rendering

    SMG720 Level 1

      Hey fellas - I'm troubleshooting some very slow rendering to H264 of a 10s MOV file and it's taking a very long time to render.  When I don't have any video effects, it takes only 15s to render.  With all the effects, it takes 300s to render.  My system is a i7-2600K, 16GB RAM with GeForce 560 GTX 2GB VRAM card. By disabling video effects one at a time, I've narrowed it down to the Luma Corrector, HLS and Unsharp Mask that account for a large percentage of the churn.  Anyone else notice this and any ideas on improving it?

      Many thanks.
