It is working.

You are great.

Once again many many thanks for prompt reply.

Sir
I am using the following expression from your document Mastering Expressions.

delay = 5; //number of frames to delay
d = delay*thisComp.frameDuration;
thisComp.layer(index – 1).position.valueAtTime(time – d)

Following expression is applied to the Top layer (to create a circular motion):
[(thisComp.width/2), (thisComp.height/2)] + [Math.sin(time)*250, -Math.cos(time)*250]

Subsequent layers are having your expression to create a trail.

Now I would like to STOP the TRAIL at some point of time. So that the entire trail is visisble. Normally what happens all the layers acquire same position after completing the circular motion (if I made to stop the TOP layer).

Kindly help me.

Thanks Mr. Kevin for useful suggestions. I will try them and get back with report.

Dear Mr. Kevin

Thanks for reply to my query. Actually I have tried SIMPLE SPARKLE effect of PARTICLEILLUSION3.0.4 in AE CS4 and able to get good results. However the bumpy effect and shining of STAGE LIGHTs could not be achieved. The real problem is the GLOW available in ParticleIllusion STAGE LIGHT effect. I am not available to generate it.
Is there any plugin required to generate the similar effect or can be achieved with present AE CS4 software.
I have already tried EXPRESSIONS (written by Mr. Dan Ebbert) and found them very useful with layers. Please convey my best regards to Mr. Dan Ebbert for useful information.
My idea is to generate those effects using shape layers. Whether I could get it in AE CS4.

Thanks and regards

Please try to render individual composition one by one. Once I had the similar problem. I created AVI files for individual composition and everything was fine till I get the real culprit to be the less Hard Disk Space. However I completed my video by importing and rearranging all the AVI files in AE CS4 and creating the final AVI file. Good Luck.

Can anyone help please.

Found very useful. Please illustrate how to use the following: –
Inertial Bounce is like making your moves “rubbery.” Layers will overextend, then settle into place on position and rotation keyframes.

// Inertial Bounce (moves settle into place after bouncing around a little)
n = 0;
if (numKeys > 0){
n = nearestKey(time).index;
if (key(n).time > time){
n–;
}
}
if (n == 0){
t = 0;
}else{
t = time – key(n).time;
}

if (n > 0){
v = velocityAtTime(key(n).time – thisComp.frameDuration/10);
amp = .05;
freq = 4.0;
decay = 2.0;
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{
value;
}
