Okay, so I was staring out my window in my bedroom and I was looking at a bunch of trees and beyond those trees there are alot of mountains(I live in AK)
All of a sudden I just visualized a HUGE nuclear explosion, and automatically thought to myself, I should put that into a movie.
And I was wondering if anyone on here could help me. I looked in Visionlab Presets but couldn't find exactly what I was llooking for. I decided I'd probably have to create my own.
What I am honestly looking for, is just a huge Mushroom cloud type explosion.
Could someone help me?
Aside from that.
I wanted to make a scary movie that had a ghost or phantom haunting a house, it would be sort of a smokey like figure. Any advice on how to go about this, or either of these effects?
Replies would be greatly appreciated.
Thanks

A proper mushroom cloud is a bit tricky, and will either require a very advanced particle engine, such as is found in high-end 3D applications, or stock footage. You could conceivably use multiple emitters in Vlab to create a similar effect, but I'm dubious that you could get quality results with Vlab's engine.

As far as a ghost or phantom, that should be fairly straightforward. Film the person playing the phantom on greenscreen, composite them into the scene, reduce the transparency so they are see-through, and perhaps use a glow composite to get them all glowy. Throw in a few grading filters to shift them toward a blue hue (or whatever color you prefer)and I'd probably create a duplicate layer and blur it a bunch to add to the glow and soften their appearance.

If you want them to move without walking things get a bit tricker, as you will either have to use a harness to hang them (somewhat dangerous, tricky, and possibly expensive) or create a rolling platform they can stand on (even a skateboard could work) that could be painted green and also keyed out.IF you want them to float in the air, this is probably easiest to just animate after the fact, shifting their position so they are off the floor.
