1)remove x=1; from the dynamic movements, its of no use when a variable is a constant,
2)secondly use a static movement ( movmnent ), there's no need to use a dynamic one
3)Remove the Misc/Set render mode from the effect list in the effect list.
4)Instead of using two fast brightness' use one Multiplier APE ( By UnconeD ), I think that will be faster.
5) TIP( Not to improve speed ): For a better looking preset, in the effect list, put the fade out before the effect list. so the position of the fadeout will be:
+ Effect List
