Trapcode Particular - repeated photos in grid mode
on Jan 31, 2012 at 6:29:00 pm

I'm sure someone must have asked this question before... but my search didn't result in finding exactly what I need.
Well, here is the problem. I have about 50 photos which I need to put into a grid that will be slowly revealed. I DO NOT want any photo to be repeated. I used Particular in grid mode and used Layer Emitter to make a grid into a certain shape. But no matter what I tried I always end up with repeated photos! BTW photos are precomped into a comp that has one photo per frame. On particular I used Sprite particle type in Random still frame mode - but that repeats the frames. Current frame - freeze mode doesn't work with Grid Emitter too well. In Periodic Burst type I didn't get any results. In Travers type the particles did not want to fill in the shape. For some reason even if they are set to be born 30 fps they are not! and I end up with about 15 particles on the grid instead of 50 that are in my precomp. I was trying to change the frame rate in the comp and the precomp. Didn't get any results. I'm kind of stuck now.
Does it mean that I need to manually create a grid with all 50 photos?!
If so, it amazes me that the guys from Trapcode didn't think of a way to make Particular to be able to NOT to repeat frames in the grid mode!!

Manually placing photos in a grid is fairly easy to do in Photoshop.
However, doing it in AE with an expression would be even better!

Check out the grid code on this tutorial: http://library.creativecow.net/articles/ebberts_dan/noise.php It should help.

Then you could use your grid precomp with Card Wipe for your transition if you wanted to.

Not sure of the final result you're after, but Card Dance may be a better tool.

Another option for manually creating grids -- PlaneSpace [link]. I think this one's a must-have if you need to arrange large groups of objects, but maintain more control over them than a particle system allows.

Walter's right about PlaneSpace - I purchased it as part of the Red Giant Effects Suite, and it's indispensible. If you look on my website in the Video Gallery:

http://bourkemedia.com/?page_id=7

And click on the Waters Corporation clip, at about :42 seconds you'll see a couple of spherical matrices created in PlaneSpace. They were created by simply dropping the clips into a comp, then applying Spheroid Creator, one of the many options in PlaneSpace. To have done this manually would have blown the budget out of the water (no pun intended). The depth of capability in PlaneSpace is huge, with options you have to play around with to see the power. You can even set up a spherical matrix, turn on "animate postion", then go in and change the settings, and you can animate between different sizes and layouts of spheres.

Wow, lots of cool stuff! Definitely got to get my hands on Plane Space...
Still, without Plane Space, what would be the best way to make a photo grid that forms a Christmas tree - 2 dimensional one - and be able to keyframe fading in (opacity) of the rows of photos? And not to have photos repeated.

Thanks!

One way:

In Photoshop place the photos roughly where you want them and then use the align tools to make them a proper grid. (Or even turn on grid options and speed that process up.)

Import the PSD into AE.

Pop the PSD precomp into your main comp.

Create a Ramp (gradient) on a new solid.

Posterize the ramp so that it has a band of color per row of pictures. (Maybe use Mosaic instead?) Line it up with your picture precomp.

Precomp it (move all attributes).

Apply the gradient map transition to the PSD precomp and use your Ramp precomp as the map.

Thanks Michael,
I took some expression class some time ago. I've forgotten most of it but I do remember it was possible to write an expression that if one object intersect with another its opacity will change. Maybe that would be a way, using a big solid for example as an "effector" effecting the opacity of photos to reveal them (by moving the solid) ... The photos would have that expression.

Though, your solution seems to be much easier to execute. But how would you make sure that banding aligns with photos? My photos are sort of rotated randomly and overlapping each other a bit (so it more looks like a random pile).

I like your idea of a large "effector". That's how I would do it in Cinema 4D.

It's a random pile? Well, that changes a few things. I think all of us were thinking your photos were in an actual grid-like form.

Actually, I still think Card Wipe or Card Dance would be the thing for you. You can use fractal noise in a precomp as a map to move the cards around and rotate them to give them the randomness you need. Then you'd do a similar transition to what I mentioned, although you might not even need the posterizing part of it.

Another alternative - ignoring any of the previous suggestions - would be some form of a Follow The Leader expression applied to your photos' opacity. http://www.motionscript.com/mastering-expressions/follow-the-leader.html

Particle Playground is another option. Here's a tutorial I wrote a while ago that will be helpful in this instance - http://library.creativecow.net/articles/kahlenberg_roland/game_pp.php
