Correction… It did work solve it for a little while. But then about a half hour later it stopped working again. I’m not going to restart my computer 16 times a day. Any suggestions?

It depends on what program you are using to create particles. In Trapcode Particular you can set your emitter as a single point… an entire area like a cube or sphere… A light… a Grid… or for your purposes a layer.
If you reference your Resolved logo you can set each of your particles (Birds) to only emit from where your logo is. I would suggest changing your velocity to zero and your particle life to more than the duration of your comp. You may need to keyframe the particles per second amount from however many you need to zero and then drag your layer to the left so that your particles are born before your animation starts. This way you won’t have birds popping on the screen out of nowhere. After your birds have been on the screen for the amount of time you feel you need your logo to resolve… keyframe some of the physics attributes within Particular, especially under AIR (Wind, Turbulance Field, Spherical Field), and it will allow you to disperse your birds from their original logo formation. Keep in mind you will be reversing this entire motion so don’t make it too abrupt.
Other’s may have different techniques for this, but this is how I would go about pulling off your effect. Also I should mention this was based on Trapcode Particular 1, it may be different or far easier in Particular 2.

Yes that tutorial should help. Think about the problem in reverse. Your particles can start in the shape and then generate from there. Then take that clip… Pre-comp it and reverse it.
Trapcode Particular is good for this technique.

CMYK is strictly print (ink). Why not create your effect in AE with the Particles… Export a single frame or frame sequence… then convert that to CMYK?

You can use many different programs to make it, but after effects will work just fine. It depends on what parts you are trying to create. Some of the scenes have the camera rotating around the character. With a shot like that you would need to use some sort of 3D tracking software like Syntheyes or BouJou. If you just have a locked off or single direction shot you can use after effects alone. The light wisps can be created with techniques like this: https://www.videocopilot.net/tutorials/3d_stroke_effect/ or https://www.videocopilot.net/tutorials/audio_to_animation/ or https://library.creativecow.net/articles/kramer_andrew/nano.php_2/ or https://library.creativecow.net/articles/kramer_andrew/nano.php I realize all of these are from Andrew Kramer’s site, but that was just the first place I remember seeing these. Creative Cow , Aaron Robinowitz, and many others have these tutorials as well.

I don’t think greenscreen is the big trick there. The Chrome effect was either a rubber suit or completely CG. Is the transition what you are trying to figure out or is it the effect itself?

ahh… I think I understand what you are trying to say. Are you trying to get the points themselves to animated, thus changing the shape of the triangle? If that is the case you should be using the puppet tool rather than Nulls alone. If you put a puppet tool pin on the point of each triangle corner, you will be able to animate each point individually and it will change the shape of your triangle. If you are using motion tracking:
Apply the track to a new NULL.
Set an expression for the Pin Point that you would like to be attached to that NULL. ( option click the stopwatch and pick whip to the position attribute of the NULL. )The point on your triangle should follow the position of the NULL.
**** This technique might result in the lines of your Triangle Bending in either direction. You can fix that by decreasing the amount of triangles in the mesh to as low as possible. If there are any bends in the triangle after that set Stiffness pins to an incredibly high percentage and position them near the bends.Another work around for this is to use Corner Pin Effect. You can set each of the corners to different tracked Nulls. You can even set two to look at one Null, but you may need to add a -1 or +1 to the end of the expresssion string of one of your Corner Pins. Otherwise you may get wierd results.

This works, but only for limited applications. The problems come when a pixel that is part of the moving object is exactly the same as one on the still background. Then you will have a transparent pixel in your moving object. Also you need to have a very good quality camera because if there is any slight lighting change in the Background or any artifacts that pixelate, you will have holes in what is supposed to be your BG Matte. Either way you might end up doing a decent amount of rotoscoping.

Trapcode Form does an excellent job of making this type of effect easy. Modifying this type of project would pull off the look you are going for: https://www.trapcode.com/movies/TextToSand_h.mov
