I got some trouble with a fluide fx,he was made by someone else and i'm the third person on it.
The movement of the explosion is done with a scale on the fluid box and the camera zoom on the explosion (i know it's a bit corny but ,...ask the realisator)...my problem is, as the camera move closer to the explosion,the top of the nuke fx is flickering,the progression dont look smooth. maybe it's due to the scale?
any id??? or advice???

There are a couple of things you might be referring to.
1. The fluid at the end either hits the top of the fluid volume or the camera near clip, revealing the fluid interior. The fluid could be extended if it is the former, although you will need to rebuild the cache. If the latter then the near clip could perhaps be lowered.

2. The exploding motion of the fluid is not motion blurred and the texture frequency is quite
high, resulting in a jumpy bubbling effect. Motion blurring is not supported on the fluid, although one could render subframes and composite the subframes together. If the fluid is cached on frames it will interpolate the density values for subframe renders, so one doesn't necessarily need to cache at the subframe rate.
