Suggestions for effects
Somebody wants me to add background effects to this trailer I cut together for them last year, only there are no greenscreens, the background isn’t a solid color, and I’m not sure how to add the star and light effects they’re asking for without at LEAST a solid background color so I can key everything in. And also without it looking terrible and fake. Does anyone here have any suggestions, or can guide me to some tutorials that can help me through this issue? So far I’ve tried creating a twinkling star background, but I’m not sure how to make it so it doesn’t overlap the actors (who move around quite a lot).
(and, yes, I am extremely new to After Effects so I’m sure there is some obvious solution I’m overlooking. I’m basically having to teach myself so I would appreciate any sort of guidance at all)

It’s hard to offer suggestions without actually seeing the video. My initial impulse (without seeing anything) would be to do some 3D motion tracking and add some graphics stuff that “sticks” to the moving camera or objects moving in the scene.

Here’s the video (it’s not great, I know): https://www.youtube.com/watch?v=ieB-_-vnJ2k&feature=channel_video_title
I’ve also been thinking of using some still images of stars and messing the blending to try to make it look like it’s part of the wall rather than something separate.

One thing you could try are particle effects. You’d essentially create a 3D layer that follows a skate, an arm, a hand, etc — then you cause that layer to emit particles. You’d have to do a fair amount of rotoscoping whenever someone passes in front of a particle, etc. This can get pretty complicated but it’s also a lot of fun. Here’s a tutorial I just came across that shows the basic technique (there are others out there, but I can’t find them at the moment):

Thanks so much! Hopefully I’ll be able to do the rotoscoping.

Thank you! That’ll certainly come in handy.
