Motion Blur Methods? Box? Pyramid? eh?

(Before anyone asks, I HAVE already done a search on "box and "pyramid" within our extensive KB.)

I've been recently experimenting with adjusting my Project Properties, and have come across this within the Menu: File > Proj Props > Video > "Motion Blur Type" > PYRAMID & BOX? - Asymmetric or not, just what are they? What do they do? And where would I use this selection?

Sounds terrific - only need to know what they do now!

Just fumbling thru the help file I found this:

"Pyramid
Gives more weight to the central frame in the blur and the least weight to the outer frames. A linear slope is used between the central and outer frames."
Box
Uses an equal weighting for all frames, essentially averaging the frames in the blur.

The Gaussian (asymmetric), Pyramid (asymmetric), and Box (asymmetric) settings use only the left half of each curve, from the central frame back. Asymmetric settings create a hard leading edge with a trailing blur behind the moving object.

Something I learned today.

Sorry Grazie, didn't read your post enough. I should be in bed here in Illinois.

They only make a difference IF you're using Motion Blur via the MB envelope on the Video Bus Master.
