That's because the script uses blur tags. Blur effect is very time consuming 
and the algorithm I use do a complicated initiation the first time it is call. 
It is this initiation that cause the playback pause a little while. But once 
the initiation finished, blur operations (of the same strength) get significant 
acceleration (at least 2/3 caculation will be saved.) 
It is a defect, and I'll try to optimize the initiation, but a perfect solution 
may not exist. Sometimes we have to trade accuracy for speed, or in the 
opposite way.

i think it would be better to have 
blur, anti-aliasing, bilinear/trilinear on/off options
