Smart Smoother HQ Rendering Speed

Here are some rendering speeds for a 352x480 30fps clip in VirtuaDub when using various filters (examples of effects). All processing was done on an AthlonXP 2600+ system with DDR PC2700 memory.

Temporal Smoother - constant 48fps, regardless of what setting was used (tested at 2/4/6/8 values).

Smarth Smoother High Quality - Radius setting has the most effect, average vs weighted has little effect (roughly 0.5fps difference), difference vs no-difference has little effect. Threshold has the 2nd largest impact on processing speed (radius setting has the largest impact).

r05/t005 - 22fps
r05/t010 - 20fps
r05/t020 - 19fps
r07/t005 - 14fps
r07/t010 - 11fps
r07/t020 - 9fps
r13/t005 - 6fps
r13/t010 - 4fps
r13/t020 - 3fps

For live-action, I like "r5 t10 a254 m5 weighted w/ difference". For cartoons with large areas of flat-color, "r7-9 t10-15 a254 m5-10 average w/ difference" is my preferred (depends on the source).
