All right, things are getting more clear for me. I tried the “source channel mapping” settings. I selected all clips and inverted channel 1 and 2. So now channel 1 is playing track 2 and channel 2 is playing track 1. But in the source monitor I still need to put the audio from track 1 (which has audio) to track 2 (which doesnt has audio) and back to track 1 to actually hear something.

This doesnt make any scense. Please help me out on this one!

I allready thought I needed to go to the expression forum. But this will help me out big time!! Thanks for the help and quick reply!

Hi Dan,

Thanks for your quick reply. I allready tried another way. It works a little now.

What I actually try to accomplish is that (i use the suretarget plugin from videocopilot) when I move around between target, the camera zooms out a bit.

I got this expression now:

nummer = thisComp.layer(“Null 5”).effect(“SureTarget”)(“Slider”);

if (nummer == 1 || nummer == 2 || nummer == 3 || nummer == 4 || nummer == 5 || nummer == 6 || nummer == 7 || nummer == 8 || nummer == 9 || nummer == 10 )
{5}
else
{2}

It’s a bit amature I guess, but it works for now.

My new problem is how to let the camera ease while its zooming in or out.

The current situation is:

I got 1 Null object witch controlls the suretarget plugin. It’s manually keyframed.

Another Null is copying the output from the slider witch the plugin use, into its own slider control. On this one I have the expression witch you saw above.

Finally, my camera (cam optionszoom) has the expression:

thisComp.layer(“height”).effect(“Slider Control”)(“Slider”)*100

That multiplies the output 5 or 2 from the second Null to give the camera some altitude.

But how can I ever manage to let the cam ease its zoom?

Hi Filip,

Thanks for your reply. I allready thought it would be complicated. What I try to accomplish is something like this:

https://www.istockphoto.com/stock-video-3446726-cells-under-a-microscope-seamlessly-dividing-in-1080-hd.php

I need a microscopic view of cells. But if I set up a particle system with Trapcode Particular, they just go over each other. And it doesnt seem to have a function witch let bounce of individual particles.

Excuse me for my bad english.

Greetings Marten

Never mind. I found something that looks like what I was looking for:

delay = 5;
thisComp.layer(thisLayer, +1).transform.opacity.valueAtTime(time – delay)

[Marten Kopp]

Thnx man. That worked out great!

Hi dan,

Thnx for the help. But it still doesnt do what Im looking for. Solid 2 scale’s along with Solid 1 but it needs to go the oposit direction, like this:

s1 = 100
s2 = 100

s1 = 150
s2 = 50

s1 = 200
s2 = 0

etc..

[Marten Kopp]

Thnx for your reply. But that wasnt exactly what i ment.

What I’d like to know is this:

What expression is needed to let one layer shrink the size the other layer grow?

[Marten Kopp]

It’s actually your final solution witch fixed mine.. just 2 hours for my deadline.. with no sleep 😀
