[CaptainMench] “I don’t want it to loop the way it is… it isn’t seamless and would jump every 5 seconds.”

My bad. If the movement isn’t seamless then things get a bit more tricky and is dependent on the actual parameters that are used. You’re in the right direction with the U key, but the UU shortcut key may actually be better in this instance where non-animating parameters may have an effect on the look and speed. Parameters like speed, or any physics-related parameters may not require keyframes to affect the speed or velocity of an effect.

[Aharon Rabinowitz] “I like the way it looks at 1:09 but I want it to look that way at frame 25. So setting a keyframe on the frame I like(1:09), and then moving it to a different frame brings that look (or that value) to the new frame (25).”

I do stuff like this pretty often. When it comes intricate 3D moves with lots of speed changes, it can get really tricky to do something like this. I actually wrote to Adobe to see if they can do something about this.

My idea is that I may have a keyframe at :25 but have my timeline indicator parked at 1:09. What I’d like to be able to do is to keep my timeline indicator where it is but make interactive changes to the value of the keyframe at :25. Right now there is no way of achieving that. My email to the folks at Adobe was to allow for a modifier key and a mouseover, over the keyframe so that scrubbing the values can be initiated.

Ant thoughts on this and perhaps other methods to get this working elegantly?

The easiest way is to loop the keyframes. Ensure that your timeline and layer are set to the desired duration. Then select each parameter’s keyframes and use the Expression flyout menu to sellect Property->Loop. There are four of them to choose from, select the last one in the list.

Thanks for the info Aharon. You may also want to have a look at https://www.synkaudiostudios.com/ which sounds like they have lots in common.

I’d love to take a look at Cinescore. Can you email me your contact at Sony? I’m working on a pro bono for the local ACM SIGGRAPH and it may be useful some time soon.

Apologies – I hit the POST key too quickly. My last post provided for a recipe that works for setting the Lifespan for all particles – on or off-screen.

To kill off particles that are off-screen, well … we’ve gone thorugh this a few times before. I suggest that you perform a search for “particles” and “kill OR Lifespan OR killing”.

Again, we went through that a few times.

Perhaps you are having issues with understanding how simulated particle generation works. I suggest that you look for this topic in the manual. I believe that my Particle Playland COW tutorial covered this paradigm sufficiently.

Cheers!

There is a Lifespan parameter in particle Plagyround. It is found in the Persistent Property Mapper. What you need to do is to create a slightly larger than ‘final comp’ sized mapper that is full-on white and use that for the Lifespan parameter.

‘Final Comp’ is defined as the composition where you will be performing your final render. If it is NTSC D1, which is 720×486, and depending on the size of your particles, you will add 720+bufferArea+width of particle, to the width of the property mapper AND 486+bufferArea+height of particle, to the height of the property mapper. The bufferArea is a userdefineable area which should be perhaps 5-10 pixels in size – just for the sake of ensuring that the buffer works.

This procedure will create a property mapper which can be applied to Lifespan which is larger than your ‘final comp’ size so that particles do not get clipped while they are at the edge of your comp.

You can fade out the particles using the appropriate slider below the propery mapper parameter.

You may want to look at my Particle Playground COW tutorials to have a better understanding of Persistent/Ephemereal Property Mappers.

Try adding a small amount of noise to the blue channel of the image in question. This normally helps to stop the banding.

I have a couple of Particle Playground tutorials here at the COW. Just head on to the AE Tutorial section and do a quick search for Particle Playground.

Dan Ebberts also has one or two here at the COW.
